Your jiakong free test drive commemorative edition from elm327

Let me control a like sports cars suitable for a family of three open  elm327  , can be considered in some ways playing, but from the qualities that may be able to find some other people hardly noticed. Furui Di is a plain-looking Kia, however, opened up and made me very pleasant.I test drive this lucky di Premium Commemorative Edition appearance basically no change, the color and material of the interior is more beautiful than the regular version, look more on the grade, so the price of 122,800 yuan before the price remains the same . In general we will discover it in the utilization of space, ride comfort and economy, but when I pressure a speed of 40km / h over a speed hump to get a family car, I feel can dig out Furui Di unknown secret.1210kg curb weight of the lucky di 123 horsepower 1.6L inline four-cylinder aluminum engine, traction, the initial stage of accelerated particularly sensitive, low-speed torque very satisfactory, you can even give the passengers in the car to push back, but After all, 4-speed automatic transmission gear ratio designed to reasonably can not make up for the halfway accelerate the weak, but a 4AT the timing of the shift is very satisfactory, basic normal driving speed is maintained at below 2000rpm.4AT not only did not let me down, but very good fit with the driver shift frustrated, even in the case of a cold car almost imperceptible. I think in terms of fuel consumption also plausible, $ 300 gasoline ran 470km in city traffic, 80km / h, cruising in the loop, the engine speed is maintained at 2000rpm. MIIT manual transmission and automatic transmission fuel consumption per hundred kilometers short of the 0.1L, so no need to worry about the high fuel consumption.The  elm327  same 1.6L 4AT Buick Excelle, Ministry of Industry and fuel consumption of 8L/100km, the the 0.9L Bifuruidi high; 1.5L new generation CVT Dongfeng Nissan Sunny hundred kilometers to the 5.8L one hand, accounted for the technical light, on the other hand curb weight full light 200kg is the most fuel-efficient one of the main reasons. Furui Di 1.6L hundred kilometers in the best score of 12.2 seconds, still good as a family car.Driving Furui Di commemorative edition I tried to break the dull atmosphere, because the hard road feel clear suspension system have given me a hint of some of the challenges, so in an open corner impose a 60km / h speed through my period hope in the tires screaming and disappointing understeer did not happen, instead of the rear of the vehicle steering wheel hesitate to follow last through at the same speed, the tires of the new Focus has long protested this point, I Furui di handling another layer of confidence.

Principle of full grasp of automotive uobd2 airbag

With the development of transportation, despite the travel more convenient, but also more security risks. When the major automobile uobd2  manufacturers in the design models more consideration to the safety factors of the car, which is consumers would like to see and in line with market trends. The last straw as a car airbags role. The following, we are concerned that some of the wide range of automotive airbag.

    
The body passive security the auxiliary configuration, airbag increasing attention has been paid. When car collides with an obstacle, it is called a collision, collision crew and car components, called the secondary impact, the airbag in a collision, before the second collision quickly open a gas-filled cushion, so the crew due to inertia moves "flutter in the air cushion" thereby alleviating the crew have been hit and absorb the impact energy, reducing the degree of occupant injury.

    
The driver's seat, at the most, however, vice driver's seat, dual airbags, is often said. In some high-class models, front side airbags, front and rear head airbags, etc., in luxury models, the rear side airbags, front seat with knee airbags. The care of the passengers can be described as looking around all sides. But then a comprehensive security configuration, also need to drive carefully.

    
The principle of the structure of the airbag

    
Modern airbag system is provided by the crash sensor, buffer airbag, the gas generator and a control block (PC). . Wherein the control computer is the core, and is generally integrated in the microcomputer. When the car involved in a collision, the electronic control unit receives different locations of the body deceleration signal coming from multiple sensors, after repeated continuous analysis, comparison, calculation, and decide whether to issue an ignition signal. Request control means can very accurate judgments made in the complex case of collision, the ignition timing must be precisely controlled.

    
Old and new airbags distinction

    
The the old airbags disposable blasting, the sudden release of energy, will inevitably hurt the vehicle occupant. The new airbags Add scalable the inflatable or release of pressure device, to prevent a sudden point explosion generated enormous pressure on the human head injuries, particularly in the passenger not wearing a seat belt when. This is about the ignition of the rocket. Length booster pusher first combustion, and then burning the next.

    
Airbag release limited

    
In order to ensure the airbags opened at the appropriate time, the car manufacturers are provisions of the airbag detonation conditions, only to meet these conditions, the airbag will pop up. Come crashing in the number of traffic accidents, the vehicle occupant, even life-threatening, the vehicle close to retirement, but the explosive conditions amounted to less than the airbag, the airbag or not open.

    
The airbags Open need the right speed and impact angle. Theoretically, only the front of the vehicle of approximately 60 ° between the position of the impact on the stationary object, the speed is higher than 30km / h, when the airbag is only possible to open. The speed is not understood in the usual sense of the speed, but the speed of the collision of the vehicle relatively rigid fixed obstacles in the test chamber, the actual collision speed of the car is higher than the test speed airbag in order to open the mentioned here.

    
Note airbags

    
The airbag cause greater harm to children, so the children as much as possible not to take the passenger seat and must sit to close co-pilot front airbags. Some senior models equipped with pressure sensors under the seat, under pressure to determine the size and weight, which control airbag release or not to open, which is actually very advanced. Airbag is life, generally 10 years to be replaced, or the chemical composition failure, the airbag not open.

    
Passenger airbags in the top of the right side of the center console, do not put in here what items.
Otherwise, once the airbags work becomes slingshot. May be subject to greater harm. With airbags, even if the whole car has airbags, must wear a seat belt, the fixed pulling no seat belts, airbags can not play a bigger role. According to the survey, a separate airbag accident mortality rate can be reduced by about 18%, the use of seat belts alone accident mortality rate can be decreased by about 42%, while the accident mortality rate can be reduced by about 47% when the airbags and seat belts used in conjunction with . Shows that only the two complement each other to the maximum possible reduction accident mortality.

Test drive Wuling Rong Guang lexia 3 upgraded version

The car the countryside Engineering pulling the slightly off the market's rapid development, driven mini cars to enter the nascent rural market. Slightly off the market, Wuling has a great market awareness, and opened up a large new upgraded version of Wuling Rong Guang slightly off the market, up to 4300 liters of cargo space, as well as the power of the 1.5-liter twin VVT engine performance, fully meet village up the goods manned transportation needs, and Wuling durability of the product over the years has been recognized by the user, monthly sales of 30,000 units of performance, becoming the highest brand awareness of slightly off the market.For micro-off, we are more accustomed to call it "facet, no a prominent engine compartment and trunk, rectangular body shape, both to meet the function of manned and can easily use up the goods. Although micro-off facing the the vast rural based low-end market, but its cargo capacity was able to bring greater value in use. Wuling glory upgraded version of the standard wheelbase models, the Dimension 4105 × 1620 × 1900mm, wheelbase reached 2700mm, maximum load space of 4300 liters nearly 620kg of cargo can be loaded, high roof height and larger The side of the door, providing greater convenience for loading cargo.Than we are still stuck in the impression of a small plane in the early 1990s, today's micro-off comfort has been greatly improved, Wuling glory seat layout MPV-like form of the second row with a stand-alone seat, and the seat can be adjusted according to the needs of users backrest angle and distance of the front and back to improve second-row passenger seating environment. Second row and third row seats can flip the higher utilization of internal cargo space, flip up rear seats, an absolutely impressive cargo space inside. In space, reducing the tailgate the threshold ground clearance, so that the user is more convenient loading and unloading cargo up and down when.Slightly off the market, you need not only it has plenty of torque to meet the power needs of cargo traveling, more need to have the best fuel economy, saving car costs, and increase the user's operating profit.Wuling Rong Guang to provide users with three engine displacement of 1.2 liters and 1.5 liters configuration models, we test drive this equipment 1.5 liter engine with 79kW of maximum power and 145Nm of maximum torque, and with a double The the VVT ​​technology well VGIS variable length intake manifold technology to enhance the power of the engine performance while reducing fuel consumption. In the field of micro-off, this 1.5-liter engine is not only on the dynamic performance, but also on the technical standards ahead of the competitors of the same type.For cargo function of the micro-off of the engine torque demand is particularly concerned about the Wuling Rong Guang 145Nm torque among the best in the same type of micro-off, but the engine is still somewhat lower than 2000rpm at high load operation, fatigue. The driving continuous climbing sections below 2000rpm traveling block 3, the engine speed feeling some fatigue, reduced to 2 block, pulled the engine speed to 2500rpm to feel some easily. When fully loaded, and only rely on low gear, the throttle to ensure that the needs of the speed.

Seven parts driders should pay attention to elm327

In more or less , elm327  will be some of the symptoms experienced several days of wind and rain and a long bumpy like overworked unwell. When the holiday is over, the journey back, we need to do the following seven parts of the car detect.
Check the appearance and paint here said the appearance of the body surface, and you can see all parts. Is inevitable due to the high speed hit the gravel road bouncing damage the finish, when checking method is to drive a thorough rinse, then two laps around the vehicle around on careful observation of the paint for scratches and other parts for damage.
Check tire after long-distance travel, some wheels visible injuries, excessive wear and tear or trauma, this time, depending on the specific circumstances, you can choose to put on the spare tire as soon as possible for further examination to the 4S shop. In addition, after a long bumpy, the positioning of the tire may fail this time the most significant feature is the vehicle appear the vehicle deviation, beating, if this happens to the 4S shop to check.
Check the engine oil Generally lack of oil after the long-distance driving is a relatively common phenomenon, and if you forget to oil the label previously added this time was not to blindly add new oil, because the different grades of oil mixed with possible adverse consequences . The experts said that the correct approach is to clear the original oil label and then select the same label to add. If your warranty period is coming, it is all simply the original oil discharge clean, then add new oil.
Check the internal parts of a part of the engine compartment after a trek need to focus on inspection, it is the air filter. If you are traveling on the way dust than the city, the air filter at this time there may be attracted too much dust and dust from entering the engine will cause wear of engine parts; air filter blocking another cause poor engine intake, a loss of power. Therefore, remove the air filter, check is very necessary.
Check the brake system through the tire to aluminum alloy rims visual Bremsscheibe surface. Brake Disc original smooth surface, if there are obvious recess, may be when the vehicle is traveling on a gravel road surface, some of fine gravel stuck in the friction surface of the brake disc between the brake disc and the mudguard, and continuously, so there are recesses . When this occurs, the vehicle may be walking issued Barang Barang "sound also heard the screams, and in some cases lost.
Check chassis owners can recall scratched chassis in the process of moving experience. Contrast before and after the car leave if there is significant change if the chassis abnormal sound, steering wheel jitter vehicles parked position grease and other phenomena, it shows that the chassis has been damaged. This is because after the the road obstacle scratch chassis, resulting in deformation of the chassis with some components, especially the upper and lower arm, the right-left direction rod, etc. are prone to deformation. Some slight touch scratch the same cause slight leakage of the machine sump or gearbox sump, which are the owners of their own detection can not be found in a timely manner. Recommendations to the 4S shop do the chassis rust care professional or sprayed with paint do the chassis "armor" to never troubles.
Speaking of glass maintenance check the entire vehicle glass you must be wondering, the glass maintenance in addition to washing with water, what else can? In fact, the glass maintenance is very knowledgeable, not all questions rinse with water can be solving the problems. For example, the glass in the soiled with oil after the naked eye may not be observable, but the wiper wiper performance will be greatly decreased, then you must use to go lipids cleaning agent to remove oil and grease. There is a permanent scratches caused on the windshield wiper inclusions gravel and stones hit the glass, resulting in trauma, and therefore can not ignore the detection of the whole car glass.

Autocom engine structure types parsing

Engine as a source of power for the Autocom, just like the human heart. However, different size and structure of the human heart is not very different, but the internal structure of the car's engine has a vastly different, different engine constructor What? Let's look together.The source of power is the engine of the car, while the engine's power is derived from the interior of the cylinder. Engine cylinder is a fuel the inner can be converted to the kinetic energy of the place can be understood as a simple, fuel combustion in the cylinder, great pressure to promote the vertical movement of the piston, the force is transmitted to the crankshaft through a connecting rod, and finally converted to a rotary motion, and then power transmission through the transmission and drive shaft to the drive wheels to push the car forward.Cars in general are mostly four-cylinder and six-cylinder engines, since the main driving force of the engine from the cylinder, it is not more good? Cylinder more In fact, with the increase in the number of cylinders, engine parts also a corresponding increase in the structure of the engine will be more complicated, which also reduces the reliability of the engine, the other will also improve the engine manufacturing costs and maintenance costs are. So, automotive engine cylinder number tradeoff choices made are based on the use and performance requirements of the engine. Like the V12 type engine, the the W12 type of engine and W16 engine is only used in a small number of high-performance car.In fact, the V-type engine, simple understanding is that adjacent the cylinder at a certain angle together, from the side look like a V-shaped, that is, the V-type engine. The V-type engine with respect to the inline engine, the decrease in the height and length, so that can be made lower engine cover, to meet the aerodynamic requirements. Cylinder V-type engine is an angle to the disposed part of the vibrations can be counteracted, but bad is necessary to use two of the cylinder head, the structure is relatively complex. Although the height of the engine is reduced, but its width is also a corresponding increase, so that for the fixing space of the engine compartment, the installation of other devices is not easy.Small angle staggered on both sides of the V-type engine cylinder, that is, the W-type engine. W-type engine with respect to the V-type engine, the advantage that the crankshaft can be shorter, and weight can also be lightweight, but the width increases correspondingly, the engine compartment will be more full plug. The drawback is that the W-type engine structure is divided into two parts, the structure is more complex, the operation will generate a lot of vibration, so only a small number of the car application.Boxer engine can be understood as the angle of the V-type engine was expanded to 180 ° adjacent cylinder arrangement (the bottom of the piston to the outside), into opposing boxer engine. The advantage is well offset by vibration, the engine running more smoothly; low center of gravity, the front can be designed to be lower, to meet the aerodynamic requirements; direction of the power output shaft with the drive shaft in the same direction, a higher efficiency of the power transmission. Disadvantages: complex structure, maintenance inconvenient; Production demanding, high cost of production, the well-known brands of cars, only Porsche and Subaru still insist on the use of horizontally opposed engine.A steady stream of power, the engine is able to benefit from the cylinder intake, compression, acting, four stroke exhaust the methodically cycle operation. The intake stroke, the piston moves from the upper dead point is moved within the cylinder to the lower dead point when the intake valve opens, the exhaust valve is closed, the gas mixture of fresh air and gasoline is sucked into the cylinder.
Compression stroke, the intake and exhaust valves closed, the piston from the lower dead point is moved to the upper dead point, the mixed gas is compressed to the top of the cylinder, in order to increase the temperature of the gas mixture, and prepare for the power stroke.
Power stroke, the spark plug will compress the gas to ignite the mixed gas within the cylinder "explosion" occurs great pressure pushing the piston from the upper dead point to the lower dead point, and driven through a connecting rod crankshaft rotation.
An exhaust stroke, the piston moves from the lower dead point to the upper dead point, the intake valve closes, the exhaust valve opens, the exhaust gas after combustion through an exhaust manifold discharge outside the cylinder. 

The  Autocom engine is able to generate power is actually derived from within the cylinder explosiveness. The combustion chamber in a sealed cylinder spark plug to a certain percentage of the gas mixture of gasoline and air in the right moments instantly ignite, it will have a tremendous explosive power, the combustion chamber is at the top of a fixed tremendous pressure forces the piston downward movement crankshaft by the connecting rod to promote, through a series of institutions the power to the drive wheels, and ultimately drive the car.

Audi RS5 get rid of the MB Star C3

Audi RS5 is bound to be a handful of dishes, I also know that this does not include me. However, this did not affect the enthusiasm of our the Cock wire family of this performance models. The reason to use such a title with gunpowder, because of M3's arrogance in the country is very assertive. In order to contend with M3, Mercedes-Benz has come up with a C63 AMG, and the Audi RS5 will also introduce the latest this point, this three pillars of the war kicked off soon.
 
Performance: 4.2-liter V8 engine freeze let one hundred kilometers acceleration in 4.5 seconds to open the hood, bright red cylinder head and the top of the carbon fiber panels bright spots, of course, this 4.2-liter V8 engine is not just the surface dressed. The maximum power of 331kW (450PS), maximum torque of 430N · m carrying data compared to the Audi S5 improved leaps and bounds (ignoring the phrase nonsense). Of course, if it is strong enough to have to look at the strength of M3 to say.Benz C63 AMG displacement up to 6.2 liters, the power of competition on the Audi RS5 and M3 contest seems to be a "perfect match" multi. Accounts, the maximum power and maximum torque of the Audi RS5 should be a small victory M3 a chip, and the final 100 kilometers acceleration performance, RS5, M3 only 0.1 seconds ahead. However, in racing culture against the clock, 0.1 seconds difference turns into a spike and spike the relationship. I write to you, I have a premonition of M3 allegiance is not satisfied with the powder.In order to gain time, Audi RS5 using the 7-speed S tronic dual-clutch gearbox. Compared to the previous gearbox, engineers improved the hydraulic system of the transmission system to further improve shifting efficiency. In addition, the four-wheel-drive system engineers still relay gearbox above the start of the article. If you remember correctly, from A5, Audi imported cars above to start using a new generation of quattro all-wheel-drive system. Set the system to replace the original Torsen central differential with a crown gear differential, the crown gear as a purely mechanical structure, under the control of the multiple disc clutch, to achieve a greater proportion of the torque of the Bi Tuosen differential adjustment range, and the front and rear torque distribution is also more flexible.Chassis part, most of the Audi RS5 using the five-link front suspension and trapezoidal-link rear independent suspension components are aluminum components. In addition to this, in RS5 who also applied proprietary damping technology: enhanced sport suspension with dynamic driving control functions, and has a three-stage variable damping characteristics. The diagonally arranged two shock absorbers by hydraulic tube and central valve connected to increase the stability of the outer wheels when cornering at high speed.To take full advantage of the powerful power output as well as to ensure the speed controllability, the the Audi RS5 selected Pirelli P-Zero series tires. The series of the tire is characterized by the use of an asymmetric tread pattern, to improve the braking performance and handling ability. Three wide longitudinal grooves on the tread to ensure high drainage performance, good performance in the case of wetlands.In order to check the head good at running the beast, Audi for its standard steel brakes, in which the front wheel brakes size from S5 13.6 inches to 14.4 inches. It is worth mentioning that the real shot models front wheel hidden set of six-piston brake calipers and 15 inches optional carbon - ceramic with cross-drilled ventilated discs, optional 12.8 inches in the rear wheels with cross-drilled steel ventilation plate.

Prevent being cheated! The J2543 maintenance

After buying a car, do routine maintenance on a regular basis to the car owners are "compulsory". However, due to the auto repair market varies greatly, some black aftermarket "aimed at owners of the weakness of the general lack of knowledge of car maintenance, add unnecessary items in the customer maintenance vehicle, or shorten accessories replacement mileage, to make a profit; while the majority of owners lack of understanding of the real situation, the deceived do not know. Recently, one engaged in the usual automobile maintenance industry for many years to "come out to admit there is a vehicle maintenance" Fudge "trick.Maintenance of the conversion of three filterWe usually air filter, fuel filter, oil filter collectively referred to as the three filters. A lot of cars are every 5000 km or so to do a maintenance each maintenance of some repair shop will be recommended for the three filters, so you can have more profits to be made. Some repair shop, always cut corners to maximum to two for the air filter to the province is often a matter steam filter may also be omitted. In fact, the car manufacturers ask for more changed every 5000 km, but also depending on the use and maintenance of the car. If the car all year round in a small gas station to refuel, running a J2543  rural dirt road, long-distance travel in the mountain hills, and 2000 km should be changed once. Well maintained vehicle condition, city driving 1-2 million km for once. In general, three filter changed every 15000-20000 km once In other words, after a lapse of maintenance time change once is enough.Maintenance of the washMay throttle when the car is not easy to fire dirty, the repair shop would advise you to be a "wash". Now the street many small repair shop banner advertising professional avoid demolition cleansing ". First with the "professional avoid demolition cleaning fluid inlet cleaning, commonly known as" playing bottle, then cleaning the throttle, spray carburetor cleaner up, the oil black Nigou rub down, tangible efforts did not waste time charge for dig 100 yuan. After three washed, the problems really disappeared In fact, as long as you wash the throttle problem can be solved more than half of the. And real effect of cleaning the inlet is fully removed, wash the job like cleaning range hoods, but it is very troublesome maintenance workers, they think that the trouble is not to make money.Maintenance of change spark plugsOil increases, may be considering a career change spark plugs, and general repair shop will recommend two or three million kilometers on the exchange. In fact, this is the quality of the spark plug, ordinary spark plugs changed every 40,000 km, Platinum, Iridium 6 to 80,000 km for the once. Here describes a way to save money: their own to buy a spark plug, dozens of dollars only expensive, but also on the hundred dollars to find a medium-sized shops, you can spend twenty dollars watched was filled. So there is a greater benefit is that we can prevent the repair shop to give your car fitted semi-new spark plug removed from the others on board.Maintenance of the engineThe engine is the heart of the car, do not understand the car is very afraid of "heart disease" car, if the car is whirring to take the blue smoke, but one the not the thing. Sent to the repair shop, they said the engine was overhaul, we have to obediently give them the car. But they do, maybe just deal with aging valve stem seals, piston ring wear, stuck ailments can be resolved. If normal driving in the city, engine overhaul to wait until after the 100,000 to 150,000 km, feel the car go up Meijin Er, could not get the speed to talk about it.Maintenance of an oil changeThere are ways to save money in the repair shop, an oil change is an opportunity. General Jetta takes about oil 4.5 liters, Beverly need at least 3.2 liters Alto you will need about 3 liters. The standard is the upper limit of the oil filler dipstick bend area. But even if you saw the maintenance Add the oil to the position is not necessarily believing. Because, like magic, he let you see, so you believe must be prepared first, he's ready to work in when to let go of the old oil. Jetta, they usually only let go four liters oil, so when injecting new oil, it can save half a liter habits do Who we do not have the rest of the oil away. For other illnesses of the car repair shop diagnosis is even more elusive, unless we live to be old to learn, or can not overpower.
