Electrically adjustable waste gate valve position adjusting method for internal-combustion engine of motor vehicle, involves adjusting position of valve depending on load requirement of engine and independent of temperature of engine

摘要

The method involves adjusting a position of an electrically adjustable waste gate valve independent of load requirement to an internal-combustion engine and independent of temperature of an internal-combustion engine, where the temperature is designed as coolant temperature of the engine or oil temperature of the engine. The valve is kept open below a pre-determined load requirement of the engine, if the temperature has value below a preset temperature level. The valve is closed or kept partly closed, if the temperature has value above a preset temperature level. The preset temperature level is preferably of 60 degree centigrade.
