5. Applications:
- Auto gearshift and turbocharged gasoline engines to improve driving comfort.
- Diesel engine to replace the mechanical vacuum pumps to save energy.
- New energy car(Electric&hybrid,fuel cell vehicles) as the complete independent vacuum source.
6.Potential market trends:
Nowadays, the automotive vacuum pressure source comes from gas engine, and the turning speed effect the Vacuum volume very much. When engine is idle or the engine flameouts, then vacuum pressure will be decreased, it will effect the vaccum booster working and vehicle safety.
Per this way, it is necessary to get a separate vacuum pressure source, for diesel, hybrid and electrical cars.
It will solve the problems of vacuum pressure shortage caused from the engine. The automatic vacuum pump assy, as the separate automobile parts exists in the vehicle, it can work separately with the 12V electric-motor only, and provide the reliable vacuum source.
