Method for controlling an internal combustion engine

摘要

The method involves operating an internal combustion engine in an overload mode in extraordinary operating situations of a hybrid drive. The engine is operated when a loading condition of an energy storage falls under a minimum value and when the engine output is larger that sum of drive outputs of the engine and an electrical machine. The overload mode of the engine is released by additional greasing of fuel-air-mixture. Independent claims are also included for the following: (1) a hybrid drive for a vehicle (2) a method for determining compression variations in a multi cylinder internal combustion engine (3) a method for operating a vehicle.
