The crank shaft rotates, the crank shaft goes to the transmission.

曲轴旋转，曲轴进箱。

So the crankshaft spins, spins a supercharger, forces air.

所以曲轴旋转，转动增压器，给空气施力。

If you make the stroke of the crankshaft longer, you'll get more torque.

如果你延长曲轴的冲程，你会得到更的扭矩。

The more fuel in the chamber, the more powerful the combustion, making the crankshaft rotate faster.

燃烧室中的燃料越，燃烧越有力，使曲轴旋转得越快。

If you make the stroke of the crankshaft shorter, you're going to lose torque, but you'll be able to gain RPM.

如果你缩短曲轴的冲程，你就会失去扭矩，但你将能够获得RPM。

So my father, being the polite gentleman he is, got out of the car, picked up the crank, and went after the guy.

所以我的父亲，作为一位有的绅士，下了车，拿起曲轴，去追那个家伙。

So as piston is forcing down pressure on the connecting rod, which is forcing pressure onto the crank shaft, you're applying torque right here.

因此活塞给连杆施加向下的压力，从而往曲轴上施力，你在这里施加扭矩。

So going back to the four strokes of the motor, the piston is forced down, as the piston is forced down, it's forced down on a crank shaft.

说回到四冲程电机，活塞被向下推，当活塞被向下推时，它被压在曲轴上。

Now a supercharger really is the same concept, it's pressurizing the motor, it's forcing air and fuel into the motor, but it uses a belt and a crank off the crank shafts.

增压器实际上是相同的概念，就是给电机加压，它迫使空气和燃料进电机，但它使用皮带和曲轴上的曲柄。

Within each of these cylinders is a piston, which moves up and down, spinning a bar known as a crankshaft, effectively converting linear motion into a rotary motion that can drive the wheels.

每个气缸内都有一个活塞，活塞上下移动， 旋转一根称为曲轴的杆，有效地将线性运动转换为可以驱动车轮的旋转运动。
