Passat 1.8T2 times the intake system refers to what
In addition to the conventional air inhalation from the air filter, in addition to the use of the intake manifold vacuum pressure difference, from the engine PCV valve (crankcase forced ventilation) pipeline connected to an adjustable intake air intake device, import appropriate Of the fresh air to achieve the purpose of improving volumetric efficiency. The use of secondary intake principle to supplement the engine combustion chamber air shortage to achieve the ideal mixture of gasoline and air (fuel-efficient), naturally enhance the explosive power (horsepower increase), improve engine efficiency. Intake air volume is adjustable The characteristics of the car to adjust the secondary intake, in order to achieve the best condition, to environmental protection, reduce fuel consumption, the effect of carbon deposition.
The secondary air intake can be the power to enhance the effect of concentrated in the low speed area, because at low speed, the air is blocked by the throttle, making the intake manifold negative pressure, then the secondary air intake by this Stock pressure, inhalation of additional air, and this additional air is caused by fuel and throttle lighter main reason, but after the speed increase, the throttle will be fully open, on the one hand when the air will not be restricted, It will not produce negative pressure. On the other hand, when the air enters and the vacuum degree decreases, the amount of air that can be introduced by the secondary air intake device becomes insignificant compared with the intake air volume of the intake pipe.
The secondary air intake is the use of the intake manifold vacuum pressure difference, from the engine PCV valve (crankcase forced ventilation) pipeline to an adjustable intake air intake device, the introduction of the right amount of fresh air to achieve the efficiency of the volume purpose.
