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

旋转，进入变速。

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

如果你延长程，你会得到更多扭矩。

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

所以旋转，转动增压器，给空气施力。

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

汽缸中燃料越多，燃烧就越强大，转动速度就会更快。

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

如果你缩短程，你就会失去扭矩，但你将能够获得RPM。

63.Could you tell the main reason for crankcase explosion?

63. 你能说明爆炸主要原因吗？

If a warning of a crankcase explosion is received, what steps should be taken right away?

如果收到爆炸警告，应立即采取什么措施？

15.What is used for sealing between the crankcase and scavenging air box?

15.什么用于和扫气空气之间密封？

What kind of precaution will you take to avoid a crankcase explosion?

为防止爆炸，你会采取哪些预防措施？

They are piston, crankshaft and connecting rod.

分别是活塞、和连杆。

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

所以我父亲，作为一位有礼貌绅士，下了车，拿起，去追那个家伙。

49.How do you measure the crank deflection of the main engine?

49.如何测量主机挠度？

They are high pressure fuel oil pipe breaking, crankcase explosion and loss of lube oil pressure.

它们是高压燃油管破裂、爆炸和失去润滑油压力。

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压力，从而往上施力，你在这里施加扭矩。

It's by means of crank deflection gauge.

通过使用偏差测量仪来实现。

When it spending at over 8000 RPM, any imperfections will cause the crankshaft to become unbalanced and create potentially distractive vibrations through the entire engine.

每分钟转动超过8000转，任何瑕疵都会使不平衡，导致整个引擎产生可怕震动。

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.

说回到四程电机，活塞被向下推，当活塞被向下推时，它被压在上。

The engine must perform constant, controlled explosions with pistons, crankshafts, oil filters, alternators, fans, distributors, valves, coils, and cylinders among the many pieces of machinery needed for the work.

发动机必须通过活塞、、机油滤清器、交流发电机、风扇、分配器、阀门、线圈和气缸等许多工作所需机械部件进行持续、受控爆炸。

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概念，就是给电机加压，它迫使空气和燃料进入电机，但它使用皮带和上柄。

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.

在每一个气缸中都有一个活塞，它上下移动，旋转一根被称为杆，有效地将直线运动转化为可以驱动车轮旋转运动。
