Caterpillar CAT diesel engine piston, piston and connecting rod

卡特彼勒CAT柴油发动机铝活塞有一铁圈作为顶上两环，这有助于减少压缩环槽上的磨损，一个空腔铸进恰好在顶环槽后的活塞里。来自活冷却喷射器的滑油流经这空腔，冷却活塞，改善活塞环的寿命，活塞具有三道环，二道压力环和一道油环。所有的环都装在活塞销孔以上，油环为标准(传统)式，滑油通过油环槽孔回轴轴箱，顶上两道环是梯形式，锥形，活塞环槽也是锥形，槽中环的作用有助于防止环因太大的碳粒而被卡住。

Aluminum piston ring as a top two ring, which helps to reduce the wear on the compression ring groove, a hollow cast into just at the top of the piston ring groove in the. The cooling jet oil is flowing through the cavity, piston cooling, improve the life of the piston ring, the piston has three ring, two pressure ring and an oil ring. All rings are arranged on the piston pin hole, oil ring for standard (conventional) type, the oil through the oil ring slots back axle box, the top two ring is the ladder form, conical, piston ring groove groove is tapered, the central role of helps prevent ring was stuck due to too much carbon particles while.

卡特彼勒CAT柴油发动机连杆销孔端有一锥度，这使连杆和活塞在最大载荷区城具有更大的强度。处于一小角度的四个螺栓连接连杆大端，这种设计使连杆宽度最小，因而可获得较大的连杆轴承，而且连杆可以通过缸套卸出。

Connecting rod pin hole with a taper, which makes the connecting rod and the piston has greater strength in the maximum load zone. In the four bolts connecting rod big end and a small angle, this design of the connecting rod of minimum width, thereby obtaining a connecting rod bearing large, and connecting rod through the cylinder unloading.
