Abstract：In gasoline engines， partial-load operation can be controlled by varying the intake valve lift instead of throttle. In the following， FAW presents the results of study on the optimisation of intake valve lift which resolves the conflict of objectives between charge exchange and high-pressure combustion processes on idle. Furthermore， this paper also shows the potential of 10% BSFC reduced by unthrottle and CVVL with the addition of high CR and CDA（3cly to 2cly） on NEDC.
