The first stoke being the intake stroke.

第一个冲程是进气冲程。

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

有四冲程，四冲程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程。

The intake stroke, piston goes down.

进气冲程活塞下降。

" 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程燃气发动。”

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程发动。

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

如果你延长轴的冲程，你会得到更多的扭矩。

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

为什么二冲程发动在船上广泛应用？

Honda's fascination with mechanics led to an incredible redesign of the four-stroke engine.

本田对械的迷恋导致对四冲程发动进行了令人难以置信的计。

This part of the cycle is named the power stroke.

该循环的这一部分称为动力冲程。

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

主为大型、低速、二冲程、十字头式，并配备涡轮增压系统。

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

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

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程。

What is the sequence of the four strokes?

四个冲程的顺序是什么？

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， 然后小型二冲程发动被抓住并开始忙碌地敲打。

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

如果你缩短轴的冲程，你就会失去扭矩，但你将能够获得RPM。

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

四冲程发动的进气门开启与排气门关闭之间有足够的叠。

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

二冲程发动因其寿命长、成本低和高可靠性而在船上被广泛使用。

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·奥托计的大型固定式单缸内燃四冲程发动。

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

因此，如果在该发动中增加压力，则在动力冲程期间对活塞施加的力就会更大。
