卡特彼勒CAT柴油發動機氣門系統修理技術

Repair technology Caterpillar CAT diesel engine valve system

卡特彼勒柴油機工作期間，CAT氣門系統控制進氣和排氣流進和排出氣缸。

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

曲軸齒輪通過兩個隋輪驅動兩個凸輪軸齒輪，兩個凸輪軸必須與曲軸時間相配合，使得活塞和伐運動之間具有正確的相對關系。

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.

每缸的凸輪軸有三個凸輪凸角，其中兩個凸輪凸角操作氣門而另外一個操作噴油器。

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

當每一凸輪軸轉動其凸角時，凸角使升桿(６)上下移動，這一移動使推桿(５)移動搖臂(１)，搖臂的移動使橋臂在缸頭的定位器上上下移動，在同一時間，搖臂通過橋臂打開或關閉兩個伐(進或排)，每個氣缸有兩個進氣門和兩個排氣門。

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.

轉動圈(３)在卡特彼勒柴油機運轉動氣門，氣門的轉動使伐上的碳粒保持最小，從而延長氣門工作受命。

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.

當升桿(６)向下移動時，伐彈簧(４)使氣門關閉。

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