Fashionable
vehicle modification, change Transponder Chip appearance, change the suspension, change
power, but in the final analysis, the depth of the potential of car
modification, the foundation will have to see the good and bad. Said
power, a lot of people think that the power of the air intake
modification is the installation of a mushroom head that such will be
able to improve the efficiency of the air intake. In fact, this is one-sided to follow up on the gas efficiency most should be the shape of the intake manifold! Different shape, length and shape of the cross-sectional area of the intake manifold, the engine design demands. Here, we are now on the shape of the intake manifold and talk.
Point of view, from the shape of the intake manifold can be divided into vertical inlet and swing inlet. Vertical
inlet intake resistance, conducive to the formation of resonance at
high rpm, to improve the efficiency of the air intake, but also
facilitate the arrangement of fuel injectors are generally applicable to
the emphasis on high-rpm performance engines; roundabout inlet favor
into gas
swirl, improve air and gasoline mixing degree conducive to generally
applicable to the emphasis on low-rpm performance engine in-cylinder
combustion efficiency, low turn improve
Here we take two extreme transponder chip key mitsubishi examples to explain. A
BMW signs, equipped with the M5 V10 engine, it does not like Japan's
Mitsubishi, Honda complex technologies to improve the response speed of
the engine, high speed, high power output, etc., instead of using the
most direct , the most pure way to achieve the perfect interpretation of high-performance. Ten
intake manifold of the V10 engine are very short vertical design, and
equipped with a throttle valve in each of the intake manifold, these
most obvious design feature is the emphasis on high turn response.
Inlet
while rotating the most obvious is the diesel engine, general diesel
engine speed is not high, emphasized the dynamic performance in low
speed diesel engines without exception all roundabout inlet. And
some diesel vehicles also deliberately increased inlet roundabout at
the end of the degree, in order to generate the maximum intake swirl, to
achieve the purpose of improve the degree of mixing of air and fuel
Understand
both the shape of the intake manifold needs of different working
conditions on behalf of, let's talk about the vortex, it is how the role
of the engine intake and combustion performance
We know that when intake air is flowing inertia. In
the swirling inlet, the flow of air can easily eddy current is
generated, because the air will be generated with duct shape close
thereto inertia. In
the speed and transponder chip reader frequency of the intake air is low, the mixture of
gasoline and air more fully, the combustion efficiency is higher, the
higher the power and economy
When
the speed increased, the speed and frequency of intake faster and
faster, this air flow generated by the inertia eddy culprit turned into a
way to reduce the efficiency of the air intake, not easy to fuel-air
mixture more faster sucked into the cylinder. In
fact, this is well understood, a roundabout piping for the air
generated by air resistance, and is certainly much more than straight
through the pipeline. So then, the vertical of the inlet is more suitable for the engine operating conditions demand
Said the above, a characteristic of the intake pipe of the two shapes, the nozzle of the arrangement position is not the same. Vertical
intake pipe because of the simple shape, small footprint, high intake
efficiency, more suitable for direct injection technology (such as
Mitsubishi's GDI), even as the BMW M5 V10 engine, direct injection, also
can spray the glib arranged very close to the intake valve
