Repair technology Caterpillar CAT diesel engine valve system

卡特彼勒柴油机工作期间，CAT气门系统控制进气和排气流进和排出气缸。

During the work Caterpillar diesel engine, the CAT valve system to control the intake and exhaust flow into and out of the cylinder.

曲轴齿轮通过两个隋轮驱动两个凸轮轴齿轮，两个凸轮轴必须与曲轴时间相配合，使得活塞和伐运动之间具有正确的相对关系。

The crankshaft gear drive two cam shaft gear through two Sui round, the two camshafts and crankshaft must match the time, has the relative relationship between the piston and the right of movement.

每缸的凸轮轴有三个凸轮凸角，其中两个凸轮凸角操作气门而另外一个操作喷油器。

Cam shaft of each cylinder of the three cam lobe, the two lobe cam operated valve and another operation injector.

当每一凸轮轴转动其凸角时，凸角使升杆(６)上下移动，这一移动使推杆(５)移动摇臂(１)，摇臂的移动使桥臂在缸头的定位器上上下移动，在同一时间，摇臂通过桥臂打开或关闭两个伐(进或排)，每个气缸有两个进气门和两个排气门。

When each camshaft rotating the convex, convex lift rod (6) to move up and down, this moves the push rod (5) mobile arm (1), rocker arm moves up in the cylinder head positioner arm bridge under moving, at the same time, the rocker arm to open or close the two cutting through the bridge arm (or row), each cylinder has two inlet valves and two exhaust valves.

转动圈(３)在卡特彼勒柴油机运转动气门，气门的转动使伐上的碳粒保持最小，从而延长气门工作受命。

Rotating ring (3) in the Caterpillar diesel rotary valve valve operation, the rotation of the cutting on the carbon particle is kept to the minimum, thereby prolonging the valve work orders.

当升杆(６)向下移动时，伐弹簧(４)使气门关闭。

When the lift rod (6) is moved downward, cutting spring (4) so that the valve closing.
