Method for controlling fuel direct injection of internal combustion engine, involves detecting lambda value by lambda sensor and temperature of exhaust gases by temperature sensor

摘要

The method involves detecting (S1) the lambda value by a lambda sensor and the temperature of the exhaust gases by a temperature sensor. The residual gas fraction in a cylinder is determined (S2) by applying the measured lambda value corresponding to a combustion process model. The temperature of the exhaust gases is detected by the temperature sensor.
