METHOD OF CONTROLLING A COMBUSTION ENGINE DURING A COLD START

摘要

The invention relates to a method of controlling a combustion engine during a cold start. A ratio control loop is executed once the lambda sensor (11), which is used to ascertain the combustion state in the exhaust gases (7), is ready to produce the correct measurements. The control of the mixture ratio control loop is activated when the operating conditions of the heat engine (1) have been verified, particularly combustion stability, and inhibited when the operating conditions of the heat engine are no longer verified.
