" 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机。”

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

一台对置活塞发动机就是单独油流量二冲程发动机。

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

有四冲程电机，四冲程活塞发动机是最常见。

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

所以让我们来谈谈四冲程电机。

The first stoke being the intake stroke.

第一个冲程是进气冲程。

The intake stroke, piston goes down.

进气冲程活塞下降。

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

如果你冲程，你会得到更多扭矩。

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

本田对机械迷恋导致对四冲程发动机进行了令人难以置信重新设计。

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

主机为大型、低速、二冲程、十字头式，并配备涡轮增压系统。

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

为什么二冲程发动机在船上广泛应用？

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

自启动器发出愤怒呜呜声， 然后小型二冲程发动机被抓住并开始忙碌地敲打。

This part of the cycle is named the power stroke.

该循环这一部分称为动力冲程。

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

随着时间推移，帮助它们攀爬翅膀拍打变成了帮助它们飞行动力冲程。

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

为什么四冲程发动机换气质量优于二冲程发动机？因为四冲程发动机在进气门开启和排气门关闭之间有足够重叠时间。

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，福特任务是修理奥托发动机，这是一种由德国人尼古拉·奥托设计大型固定式单缸内燃机四冲程发动机。

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.

四冲程发动机进气门开启与排气门关闭之间有足够重叠。

What is the sequence of the four strokes?

四个冲程顺序是什么？

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

二冲程发动机因其寿命、成本低和高可靠性而在船上被广泛使用。

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，如果在该发动机中增加压力，则在动力冲程期间对活塞施加力就会更大。
