Modified car tuning knowledge of Nissan Consult 3 brake

No matter what kind of car, the brake system is to protect the most important part of the traffic safety, more essential, powerful brakes with high-powered modified car fans, after all, the car is light strong acceleration forces can not easily stop under, will lead to serious consequences. Therefore, before further enhance the speed performance of the car, we must first to enhance the performance of the braking system.

    Let talk before conversion to understand the theory of the brake system, a 200hp horsepower, weight 1300kg car accelerates from a standstill to a speed of 100km / h may take 9-10 seconds, but the same car in violent brake case by the speed of 100km / h deceleration to a complete standstill, it only takes less than 3 seconds, indicating that the negative power of the braking system can be several times larger than the power of the power system. In physics, energy is not going away, it will only be converted from one form to another form, such as the kinetic energy is converted to heat, light, etc.. In the above example, a large number of vehicles "momentum" is the brake system at the moment all converted into heat energy, accumulated in the brake member, wheels, and road surface. And, if the brake without locking the wheels, then most of the heat absorbed by the brake parts. If the heat can not be quickly lost, would lead to overheating of the brake pads or brake fluid, making them lose their most important role - security, modified braking system, every aspect and temperature related.
Brake pads

    Original brake pads due to the care to the cost, durable, the cleaning (Brake powder) and the low-temperature efficacy requirements, generally not very high coefficient of friction (mu) (about 0.4 or less), but mostly not withstand more than 300 ℃ temperature, after repeatedly occurs performance of a recession. Therefore, the replacement of the high-performance brake pads is the first step in the modified braking system. To select high-performance brake pads do not do too large mu number of ultra-high temperature, high friction coefficient makes braking action becomes too sensitive in slow motion, every time you touch the brake pedal will make the car's passengers off their feet, in addition to brakes will wear increases reduce life expectancy.

BMW GT1 engine modification technologies

Engine internal components modified high-precision components for the use of lightweight, high strength material in order to reduce the wear and tear of the internal dynamics, reliability and balance to enhance more to take into account in addition to achieve the purpose of power upgrade. Both lightweight and high strength depends on the material advancement of technology, the application of high-tech alloys or composite materials with precision machining technology, making the horsepower generated by modern high-performance engines not only per unit volume can significantly enhance the reliability and economy resistance can be simultaneously improved.

 The modification of the valve
    Valve technology have made great progress in the past few years, the main change is that the improvement of material progress and precision. High intake and exhaust efficiency, environmental regulations, have to rely on material well valve. Valve modified principle is: does not affect the strength of the case as much as possible to reduce the weight of the valve. The precise movements valve basic elements of high-performance engine, professional tuning usually combined for consumers to choose different valve engine retrofit projects more and more stringent accuracy requirements of the valve bodies, so set the steam the door must be considered with the camshaft and rocker arm. Original valve usually have the appropriate material and size, but if there is a need to moderate replaced with a larger or smaller size. The valve material is very important, the current modified steam valve is usually with the requirements in order to the intensity enhance and lightweight titanium alloy as a material, but a set of titanium alloy valve price is not low
Valve heat via contact with the valve seat, came through the valve seat to achieve the purpose of cooling the steam valve is the most important thermal path. Therefore, the configuration of the valve seat must be very careful, if too close to the edge of the valve or steam door edge is too thin may result in poor microleakage. In addition, the surface accuracy of the precision and surface smoothness of the valve sleeve and valve, rocker arm and valve holder must be strictly require otherwise at high speed will cause serious damage. Set the strength of the valve spring must be just right, to take into account the valve microleakage not cause difficulties open spring strength greater than that camshaft to open the the steam door when overloading horsepower output is very unfavorable. The fixed seat of the valve is also a potential problem with this device is with a clip of the spring fixed in the steam on the door, which will result in the sudden acceleration and lift the engine distorted or broken, and therefore must meet to make a change.

How much do we know about modified launch x431 spring

Spring suspension system plays an impact to support the body absorb uneven road conditions and other force on the tire, where other forces, including acceleration, deceleration, braking, cornering, the force exerted on the spring. More important is the absorb shock process to ensure that the wheels do not leave the road to ensure that the tracking of the car, and ensure adequate grip and good handling.Many people say that with 4K, 6K spring, but the K value in the end what it? According to the the physical formula F = K • X we can know that the value of K is the coefficient of elasticity of the spring, by the formula indicates that the greater the value of K, the case of the same force, the stroke of the spring is also smaller, and the K value is small, and will cause spring soft enough support. Specifically, 4K spring is when you applied a 4Kg the strength to spring, and spring will be compressed or elongated 1mm, 6K is also true. K number of select depends on your orientation and shock absorber damping settings to determine. Why do some people not to see the original shock machine coupled with the short spring, because once you spring K number of inappropriate choice of damage to the original shock machine is a very large number of K will lose a certain amount of comfort, K the number of small, easily exhaust stroke of the shock machine, a mismatch it is easy to lose the car tracking.Spring type is divided into two types: straight coil springs and progressive spring. Straight coil spring the name suggests is a spiral direction, diameter, pitch throughout the spring. The formulation of the above-mentioned K-value, only for a straight coil spring because it is the value of K is a constant, for a progressive spring, the value of its K with the changes in the amount of compression change.Straight coil spring is most characteristic of the spring coefficient K value is constant, K value unchanged direct benefits is to regulate the vehicles easy to grasp, more suitable for athletic suspension optional. In the game, the K value of the constant is very important, it can provide a more rapid response, also can make the tune associated with the shock absorber damping to be more precise. Stir tooth shock most with matching tuning easily and accurately than the progressive spring. Smaller straight coil springs processing difficulty, we can do a little experiment to experience: The "spring" and a period of gradual "spring" with a wire roll for some straight, take a look at what kind of "spring" easy to make. The answer is of course a straight coil spring, the wire circle wound on the cylindrical mold, and then releasing it. The progressive spring, the need to control each turn of the winding diameter and spring distance, need a special spring coiling technology. Of course, not to say that the difficulty of processing large or small, on behalf of its performance is high or low, but their applicable conditions are just not the same.
 Another is a progressive spring, also known as variable coefficient of elasticity spring. It uses ranging from pitch circle diameter ranging design, that both ends of the circle diameter is small, the large diameter of the middle circle. Large circle diameter spring rigidity will increase accordingly, is also true for the pitch. Both ends of the spring is compressed by the force to be less than the intermediate portion, to pass only the both end portions so when small bumps and when a small impact force can be absorbed, can guarantee a certain comfort.
 Respond to body subduction because the braking, steering roll status by the middle of K values ​​larger portion to provide support and can better suppress body scroll (Rolling). The K value of the progressive spring is increased with the increase of the amount of compression will produce contact between the partial line, ranging pitch of the spring under compression, so that the effective number of turns to change, thereby causing the elastic coefficient K changes. Through the spring up and down circle diameter change is the most direct way to change the elastic coefficient K.

Off-road vehicles increased body modification

Many people already no stranger to the body for increased off-road vehicles, products now on the market to see that is spring plates and shock absorber. Body rise will affect a lot of all aspects, such as the front toe, steering system, rear propeller shaft angle and drive shaft length.
General import body increased product prices in the 8000-10000 yuan, some domestic alternative products prices between 6000-7000 yuan, this part of the product can only preliminary vehicle height by 2-3 inches, while the vehicle other basic performance does not improve, or because of the increased influence to other properties of the vehicle without any correction.
The body elevated impact and response measures
1 simply say that The body rises directly affect vehicle stability and steering system, the most affected stability can be improved by correction of the wheel alignment.
2 most of the front axle structure change due to elevated body turned to the kingpin angle and toe angle, independent suspension will directly affect the camber to solve the above problems can be adjusted by the replacement of the upper and lower arm and front wheel alignment .
Elevated make steering rod angle becomes larger, large undulating road driving is not easy to control the vehicle, to replace the steering rod and steering arm. In order to play in off-road vehicles increased the advantage while ensuring the stability of the vehicle on the road specially balanced rod connected device by the user for connection / disconnection.
Modified elevated the vehicle's center of gravity will affect vehicle stability, this problem can be resolved through external flange.
Rear suspension problems encountered larger drive shaft angle increased prone to noise and vibration, once the breakthrough reasonable angle specified by the manufacturer, and even prone to cracking, you need to reduce the transfer case and change bridge The input shaft angle.
In order to be able to play the body increased performance, with the steel plate with longer lug or collapsible lug, but these products will more or less affect the stability of the vehicles traveling on the highway. Raised may require a longer drive shaft or even completely change the driveshafts and transfer case export connection guarantee modified firmness.

Automotive interior parts cleaning nursing skills

In fact, the car interior cleaning and care with stress, before making interior cleaning, for example, should first car lights and other electrical appliances, the instrument is turned off, and then remove the dust inside the car, sweep the dirt, then vacuum cleaner compartment within various parts carefully vacuuming.Such as plastic products under the sun and wind oxidation cracking and loss of gloss leather goods appears to aging, wear, fade, fiber dust stolen goods contamination and oxidation fade, thus affecting the internal comfort and beautiful, but also shorten life.
Car seat cleaning points

   There are two general types of car seats, villi class, leather. Velvet cleaners, cleaning fluff chairs must be dedicated and absolutely can not use bleach. The leather seats real leather and artificial leather. Must not use water or detergent cleaning, otherwise not only cleaning is not clean, but also cracks. Should use specialized cleaning products leather protector cleaning leather chairs, not only can quickly clean and polish, more effective removal of static electricity, enhanced protection.
 For a dirtier leather surface, the first pre-treatment using velvet cleaning agent, because some dirt may induration on the leather surface, using velvet cleaning agent can effectively wetting and decomposition of oil, so that the next cleaning work more smoothly.
Instruments and other equipment cleaning to be properly
Dashboard panels and other plastic or leather products, the surface more pinstripe, contaminants multi possession inside. Pay attention to the process of cleaning these parts velvet cleaning agents, the Almighty foam cleaning agent, plastic care, etc., should not be sprayed appliances, switches, leather seats, seatback and body paint.
 Like the dashboard, gear position area cleaning, you must first remove the dashboard area stripes, fold, dust on the corners.
 Like cleaning the steering wheel, steering wheel, mostly leather or leather material, contaminants are mostly body oils, and not easy to clean. To in spray cleaners Rubbing, with a soft brush scrub with a clean towel to wipe. If the steering wheel coat, you want to remove it, clean glazing alone. Cleaning care requirements of the steering wheel should not sticky, not slippery.The air conditioning vents clean to be careful, and air conditioning vents materials for hard plastic grid format. The contaminated dirt dust and sand. Must be careful due to the thin and brittle, particularly in the grid at cleaning, to the grid to remove the cleaning, window grid with a small brush to clean the air conditioning vents.

Modified exhaust? Pull the wind in order to listen to the sound ?

Car engine as the power source of the car, it is the level of performance directly determines the level of the overall performance of the car. The level of performance of the car engine, not only depend on the design of the engine block, with the other parts surrounding it, such as into the exhaust system, fuel system, ignition system, electronic control systems, etc. are closely related, and intake and exhaust system as a two door gods in charge of the engine lifeblood, if one is defective, the engine will not be able to work properly, affecting the performance. But for many owners, they are more concerned about the appearance of the car is complete, rarely interested in the exhaust system of the car's in-depth study, if you want to study, I am afraid that the exhaust tail mouth. After all, the car's exhaust is difficult to see the appearance of the inside of the structure, at the same time a lot of people will think that the exhaust pipe is not clogged working.The car's exhaust system (Exhaust System) Usually constituted by the exhaust manifold (exhaust plantain), catalytic converters, muffler drum (tail drum), exhaust pipe, etc., are very particular about the design of various parts, which is more to the tail drum staggering. In addition to play the role of the muffler because the tail drum, its structure form directly affects the function of the exhaust system
This time to let everyone in-depth understanding of the tail drum, and uncover the mystery of the exhaust system, a Suzuki Wagon factory exhaust tail drum, and a modified exhaust tail drum were dismantling. As shown above, the Suzuki Big Dipper tail drum is the typical back pressure design, the exhaust gas pipe at the start ① into the tail drum, and quickly filled the the tail drum rear exhaust chamber (2) is closed due to the exhaust chamber, exhaust only to backtrack at the hole in the pipeline ③ the exhaust chamber ④ flow into the middle of the Exhaust Gas flows through the grid ⑤ exhaust nozzle ⑥, tail drum finally discharged from the exhaust pipe ⑦.The original's tail drum how simple in appearance, if not apart to see what happens, I believe we can not think of original exhaust flow is so complicated! Although the design of such a complex alignment can play a better role in the back-pressure, to enhance the engine's low-rpm range torque helpful, however, if the engine is to climb on the high-speed range, a bit powerless, but it also reduces the high turn interval horsepower output, modified tail drum is how are we doing?

BMW GT1 balance rod knowledge introduced

Car balance lever is in accordance with the purpose and function of demands, the following points, namely:1 under the front wheel swing arm the balanced lever (the original car essential accessories)- Designed and installed separately connected to the front axle and front wheel, the main role is responsible for the control of the front wheel of the medial and lateral inclination;2. Direction before the beam balance lever (the original car essential accessories)- Design hem arm mounted on both sides of the front wheel, the overall symmetry control the direction of the front wheels. The main role is responsible for the front wheel of anteversion, to maintain the direction of tracking ability of the wheels;3. The front suspension Tata top balance Trolley (Hong Kong and Macao commonly known: the top bar. Optional pieces)- Designed and installed in the front shock absorber overhead position. The main role is enhanced cabin with front body rigidity to counteract centrifugal horizontal torque caused by the frame deformation (severe deformation can cause the top of the tower tear), improve vehicle cornering ability, improve cornering speed, reducing the body by the centrifugal force generated by the roll angle;Before the end of beams balanced trolley (commonly known as: before the end of the optional pieces)- Designed and installed in front of the front axle and the frame chassis joints. The main role is to enhance the strength of the connection of the front bottom beam (front axle) and the chassis, reducing the front axle displacement deformation distortion caused by the centrifugal force with the body, and its main role is also to improve the cornering performance;5. Rear suspension overhead balance lever (commonly known: after the top bar. Optional pieces)- Designed and installed on the rear shock tower top position. The main role is to enhance the strength of the boot of the car, reducing the rear compartment due to the centrifugal force caused by the lateral distortions, reduce car tail roll when cornering, to improve vehicle cornering performance;Rear axle suspension to to enhance balance lever (commonly known: after the end of optional items)- Designed and installed at the connection position behind the rear axle and frame chassis. The main role is to enhance the strength of the connection of the rear axle and the frame;Frame (body) chassis enhancements balance lever (components)- Designed and installed in the middle of the frame chassis, the main role is to strengthen the overall frame chassis rigidity.Depending on the vehicle factory design, the frame structure is different, some have been omitted, and some other structure to replace.Family vehicles usually do not pay attention to the equipment, sports vehicles, is rather more not less.In addition, the body in order to enhance the rigidity of the body as a whole and professionally converted (cockpit) anti-roll support with side door strengthening steel beams, are highly specialized athletic essential modification project.Different models of chassis design, usually not free to substitute other models of accessories.After serious collisions, the balance rod deformed and its components, should all be replaced, rather than the heating correction can be fully restored, otherwise, even if the correction reset, but the material itself changes also affect the high speed security and stability.
