Abstract
An engine control method which can switch over the valve operating property of an engine in a step-wise manner according to the operating condition of the engine and which can control the slipping of the driven wheels through the use of a leaner air/fuel mixture so that it may not be undesirably affected by the deviations of the actual values of various parameters from the designed values of the parameters. Furthermore, a valve operating property is allowed to be switched over from a low speed condition to a high speed condition only when the output of the engine is not reduced as a result of the switch over.
