n.活塞

原形：piston复数：pistons

We use a piston engine instead.
我们改用活塞发动机。
This piston moves by steam pressure.
这个活塞在蒸汽压力下运动。
The piston moves up and down inside the cylinder, creating the power needed to move the vehicle.
活塞在气缸内上下移动，产生驱动车辆所需的能量。
The engine's efficiency is largely determined by how smoothly the pistons operate within the cylinders.
发动机的效率很大程度上取决于活塞在气缸内运行的平滑程度。
A malfunctioning piston can cause the engine to misfire or lose power altogether.
活塞发生故障会导致发动机失火或完全失去动力。
The mechanic checked the compression of each piston to ensure optimal engine performance.
机械师检查了每个活塞的压缩情况以确保发动机达到最佳性能。
The piston ring is responsible for sealing the space between the piston and the cylinder wall, preventing gas leaks.
活塞环负责密封活塞与气缸壁之间的空隙，防止气体泄漏。
In a four-stroke engine, the piston completes two full cycles of up and down movement for every power stroke.
在四冲程发动机中，活塞每完成一次动力冲程就要上下全行程两次。
Overheating can cause the piston to expand and seize within the cylinder, leading to engine failure.
过热会使活塞膨胀并在气缸内卡住，从而导致发动机故障。
The connecting rod connects the piston to the crankshaft, converting linear motion into rotational motion.
连杆将活塞与曲轴连接起来，将直线运动转换为旋转运动。
High-performance engines often use lightweight materials for pistons to increase their speed and responsiveness.
高性能发动机通常使用轻质材料制造活塞，以提高其速度和响应性。
proper lubrication is crucial for the longevity and smooth operation of pistons in an engine.
适当的润滑对于发动机中活塞的长久使用和顺畅运行至关重要。
