The electrical section contains the solid-state proportional temperature controllers and solenoid valves . 电子控制室内有固体线路的比例温度控制器和电磁阀。
This device, called the manifold heat-control valve, is built into the exhaust and intake manifold . 这种装置称为“歧管热控制阀”，它拼装在排气与进气歧管中。
When the pcy valve sticks in the intermediate position, the engine idles rough and stalls frequently . PCV阀在过渡状况被粘住时，发动机会出现怠速不稳和频繁息火的故障。
Rough idle and frequent stalling could result from a plugged or stuck pcv valve or from a clogged pcv air filter . 怠速不稳和频繁熄火是由于PCV阀堵塞或者PCV滤清器堵塞而引起的。
Because of the severe limitations of this valve in respect of column switching, it was replaced by another kind of valve . 由于这种阀在柱子切换方面限制太死，所以采用了另一种阀。
Electrical signals are sent to the hydraulic valves by the microcomputer when a gear change is required by the powertrain control strategy . 当按照动力装置控制方案要求换挡时，电信号由微计算机送到液压阀。
The vacuum-relief valve opens to allow enough air to enter the tank to replace the gasoline pumped from the tank by the fuel pump . 真空阀通向大气，使足够的空气进入油箱，以补充由输油泵从油箱中吸出的燃油所占的面积。
Since cordite burns at a greater rate at a higher pressure a relief valve must be used to allow generated gas to escape to atmosphere at times when the demand is low . 因为柯达火药在较高的压力下以较高的速度燃烧，所以必须使用一个溢流阀，以便当用气少时，能让所产生的部分气体排到大气中去。
