Description
Technical field
The utility model belongs to automobile engine engine driven supercharging control device technical field, in particular to a kind of integrated gas
Motivation tool Pressure elation Control Unit.
Background technique
The main function of air inlet by-passing valve is to prevent pressure jump in air inlet pipeline in engine driven supercharging technology, will be arrived after pressurization
Pressure between air throttle in admission line is controlled in limiting value hereinafter, this limiting value should consider the needs of engine,
Also to consider the pressure limit that air intake assembly can bear, when suddenly receiving throttle, closed throttle, but booster is not
It stops working, air still enters air inlet pipeline by continuously compression, if this partial high pressure air is not in air inlet pipe
It can be drained in time, air inlet overpressure will be made to increase rapidly, it is possible to cause air throttle damage or air inlet pipe explosion.At present
The air inlet by-passing valve that mechanical supercharger mainly uses by after pressurization with connected at turbocharger inlet, under non-full load mode
