Title:
【発明の名称】エンジンの制御方法
Document Type and Number:
Japanese Patent JP2642009
Kind Code:
B2
Abstract:
To the end of improving an engine control method which can switch over the valve operating property of the 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, the engine speed (NE) and/or the load condition at which the valve operating mode is to be switched over is shifted to a higher value when a traction control is in effect (when a control process involving a leaner air/fuel mixture is being executed), the width of hysteresis of the point at which the valve operating mode is to be switched over is increased when a traction control is in effect, or the air/fuel mixture is made richer for the high speed mode than for the low speed mode.
