Specific embodiment
With reference to specific embodiment, the utility model is described in further detail.
Embodiment
As Figure 1-3, a kind of two-stage supercharging device of engine, including air filter, low-pressure stage booster, high pressure
Level booster, charge air cooler and engine；Air filtering core 4 is provided with the air filter, sky is provided with the air filter
Gas interface 5；Air compression interface 1, waste gas interface 2 and turbine is equipped with the hiigh pressure stage booster and low-pressure stage booster to connect
Mouth 3；The engine is provided with air compression interface and waste gas interface.
The air interface 5 of the air filter is connected with the air compression interface 1 of low-pressure stage booster by pipeline, institute
State and connected by compressor connecting tube between low-pressure stage booster and hiigh pressure stage booster, the hiigh pressure stage booster and charge air cooler
Connected by pipeline, connected by pipeline between the charge air cooler and the air compression interface of engine.
The waste gas interface of the engine is connected with the waste gas interface 2 of hiigh pressure stage booster by waste gas connecting line, institute
State and connected by waste gas connecting line between the turbine interface 3 of hiigh pressure stage booster and the turbine interface 3 of low-pressure stage booster.
The engine is in-line engine or V-type engine.
A kind of method of work of the two-stage supercharging device of the engine described in basis, air was carried out by air filter
Filter, the air after filtering by being sent to hiigh pressure stage booster after low-pressure stage compressed, by hiigh pressure stage compressed
Cooled down by charge air cooler afterwards, and then air enters in engine；
The waste gas of engine out, by after the turbo-compressor of hiigh pressure stage booster, is connected from engine by connecting tube
