1·The screw air compressor air intake valve has reasonable structure and reliable connection, is uneasy to leak, and has long service life and good performance.

本实 用新型结构合理，连接可靠，不易泄露，使用寿命长，性能好。

2·This problem is made worse by the small amount of air that leaks into the cylinders around the rotary intake valve.

这个问题是加剧了少量的空气泄漏进入气缸的进气阀旋转。

3·Intake stroke: the camshaft opens the intake valve and the piston moves down the cylinder. This creates vacuum and sucks in air and fuel into the combustion chamber above the piston.

进气行程：凸轮轴打开进气阀，活塞在汽缸中向下运动，产生一段真空。

4·During the intake or admission stroke, the piston moves downward as a charge of combustible fuel and air is admitted into the cylinder through the open intake valve.

在摄入或中风入院，活塞动作，作为燃料和空气中可燃负责向下是进入气缸通过公开承认，进气阀。

5·When the piston reaches the bottom of the intake stroke, the intake valve closes, trapping the air-fuel mixture in the cylinder.

当活塞到达进气行程的下止点时，随着空气燃油的混合气进入气缸，进气门关闭。

6·The Haltech idle Speed motor is a 4 wire stepper motor controlled idle valve, this valve allows the ECU to control the volume of air entering the intake manifold at idle.

在Haltech怠速电机是一个4线步进电机控制的空闲阀，此阀允许ecu的控制空气量走进闲置摄取多方面的。

7·The intake and exhaust valve opening times will overlap as RPMs rise, recycling some of the charge the outgoing air creates.

进气和排气的气门开合时间随着转速的提高相互交叠，循环着将废气排出。

8·Influence of valve timing on air intake efficiency of the variable air intake system is analyzed.

分析了配气正时对可变进气系统充气效率的影响。

9·On the power stroke, the intake valve and exhaust valve close. The spark plug ignites the air-fuel mixture, the piston moves down.

在作功行程，进气门和排气门关闭，火花塞点燃混合气，活塞向下移动。

10·As the piston moves down, the vaporized mixture of fuel and air enters the cylinder through open intake valve.

当活塞下移时，汽化的燃料和空气的混合物通过进气门进入气缸。
