By utilizing electromagnetic valve, we can control opening and closing timings of intake and exhaust valves according to the operating situation of the engine. Therefore, the engine performance can be improved suitably in exhaut emission during starting, idle stability, fuel comsumption and engine power, etc. When an engine rotates in the low speed, gas flow is bad and the throttle which adjusts air mass is apt to cause the pumping lose of the engine.

中文摘要传统机械式可变汽门正时系统为分段固定式机构，无法根据引擎转速以及负载变化来提供适当的汽门正时；利用电磁式气阀可根据引擎当时状况控制进排气门的开启与关闭正时以及汽门持续开启正时，因此引擎在冷启动废气排放、怠速稳定性、燃油消耗率以及引擎性能等方面均相当之改善。
