Pistons, Rings and Connecting Rods
活塞为两件式活塞。 钢活塞顶由一个单螺塞固定在锻造铝壳体上。 活塞顶中设计有两个冷却室。 机油从活塞冷却喷嘴流出,经过活塞体中的钻孔油道流入外室。 机油进入外冷却室后流向内冷却室。 机油随后经由中心排油孔返回油底壳。 排油孔位于连杆小头的上方。
使用活塞组件上的两个活塞环密封燃烧气体。 活塞环位于活塞顶的淬火铁槽中。
油控环位于钢活塞顶的下凹槽中。 油槽底边缘有四个钻孔。 这四个小孔可把过量的机油排出油环。 机油在活塞顶和活塞裙之间排出。 然后机油沿活塞裙外侧的槽排出。
活塞顶部具有两个 1/2 -13 NC 螺纹孔,用于起吊活塞和连杆总成。
连杆的销孔端成锥形。 这个锥面在负载重的区域给连杆和活塞更大的强度。 四套螺栓和螺母将连杆盖固定到连杆上。
