" I also understand that India has now banned the two-stroke gas engine."

“我也理解印度现在禁止二冲燃气发动。”

An opposed-piston engine is a two-stroke engine with separate oil flow.

一台对置活塞发动就是单独油流量的二冲发动。

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

如果延长曲轴的冲，到更多的扭矩。

There's four stroke motors, four stroke piston engines being the most common.

有四冲电，四冲活塞发动是最常见的。

So let's talk about the four strokes of the motor.

所以让我们来谈谈四冲电。

The first stoke being the intake stroke.

第一个冲是进气冲。

This part of the cycle is named the power stroke.

这一部分循环被称为动力冲。

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

如果缩短曲轴的冲，就失去扭矩，但将能够获RPM。

The intake stroke, piston goes down.

进气冲活塞下降。

The main engine is large size, slow speed, two-stroke, crosshead type with turbo charging system.

主为大型、低速、二冲、十字头式，并配备涡轮增压系统。

Four-stroke engine has an enough overlap between inlet valve opening and exhaust valve closing.

四冲发动的进气门开启与排气门关闭之间有足够的重叠。

What is the sequence of the four strokes?

四个冲的顺序是什么？

There was the angry whine of the self-starter and then the little two-stroke engine caught and started hammering busily.

自启动器发出愤怒的呜呜声， 然后小型二冲发动被抓住并开始忙碌地敲打。

Over time, the wing beat that helps them scramble becomes the power stroke that helps them fly.

随着时间的推移，帮助它们攀爬的翅膀拍打变成了帮助它们飞行的动力冲。

Why is the two-stroke engine widely used on board ship?

为什么二冲发动在船上广泛应用？

In 1885, Ford was tasked with fixing an Otto engine, a large stationary single-cylinder internal combustion four-stroke engine designed by German Nikolaus Otto.

1885 年，福特的任务是修理奥托发动，这是一种由德国人尼古拉·奥托设计的大型固定式单缸内燃四冲发动。

Why is the air exchanging quality of four-stroke engine more than that of two-stroke engine?

为什么四冲发动的换气质量优于二冲发动？因为四冲发动在进气门开启和排气门关闭之间有足够的重叠时间。

The two-stroke engine is widely used on board ship because of its long life, low cost and high reliability

二冲发动因其寿命长、成本低和高可靠性而在船上被广泛使用。

So in this engine, if you increase the pressure, then you'll have more force on the piston to use during the power stroke.

因此，在这种发动中， 若提高压力，则在动力冲期间， 活塞上将产生更大的力以供利用。

Most birds only generate lift on the downstroke of each flap, while using the upward recovery stroke to set up their next wing beat.

大多数鸟类只在每个襟翼的下冲中产生升力，同时使用向上恢复冲来设置它们的下一个翅膀拍打。
