DEVICE FOR CORRECTING THE EFFECTS OF ALTITUDE ON AN INTERNAL COMBUSTION ENGINE

摘要

A system for correcting the effect of altitude on an engine with a supercharger. A bypass is provided to bypass an exhaust gas turbine of the supercharger and a waste gate valve is provided in the bypass. An actuator is provided for operating the waste gate valve. The actuator has a supercharging pressure chamber supplied with supercharging air, a standard pressure chamber filled with air at standard pressure, and a diaphragm partitioning both chambers. The diaphragm is operatively connected to the waste gate valve so as to open it when the diaphragm is deflected by an increase of the pressure in the supercharging pressure chamber.
