Cited Pistons pull vent valve 10-valve piston cited the role of pulling out are seized cylinder piston rod, when its mild in China emerged after the main hydraulic cylinder rod cavity and there is no cavity under the pressure dropped, so that the main hydraulic cylinder in motion the process of increasing resistance to the main pump to increase the load, resulting in engine speed when pumping declining situation.

3活塞引拔阀内泄活塞引拔阀10的作用是拉出检缸活塞杆，当其出现轻度内泄后，主液压缸无杆腔和有杆腔的压差下降，使主液压缸动作过程中阻力增加，使主泵负荷加大，导致泵送时出现发动机转速下降的现象。

Joining the 4.2L and 5.0L naturally aspirated models and the range-topping XFR super-saloon in the U.S. market, the new XF Supercharged comes with a 5.0L force-fed engine pumping out a 470hp (351kW) and 424lb-ft (574Nm) of torque - a 12% increase in power over the 4.2L 2009 Jaguar XF Supercharged.

加入4.2L和5.0L自然吸气式的模式和范围，超出XFR超级轿车在美国市场上，新芳增压配备5.0L强行灌食引擎抽水了470hp （ 351kW ）和424英镑英尺（ 574Nm ）的扭矩-增加了12 ％以上的电力2009年捷豹芳4.2L增压。

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。
