Cylinder deactivation performance in vehicle gasoline engine is investigated by experimental and simulated methods, this technology is implemented by adjusting the valve system, and furthermore, a simulated model is built in GT-power. The results show that, in cylinder deactivation mode, the overlap degree of naturally aspirated and effective region is highly, it can be considered that the cylinder deactivation engine just operates in naturally aspirated state. At 2 bar@2000 rpm, BSFC of cylinder deactivation is 312.7 g/kW h, the fuel efficiency is improved 12.6% than normal state. With the reduced engine speed, fuel efficiency becomes better, however, with the increment speed, engine NVH characteristic has been deteriorated.
