17种不同的汽车发动机类型
正文翻译
In a two-stroke engine, a piston completes a power cycle with two strokes – one up and down inside the cylinder to complete one crankshaft revolution during a single time of fuel burn.
在二冲程发动机中，活塞通过两个冲程完成动力循环——在一次燃料燃烧中，活塞在气缸内上下运动一次，完成曲轴的一次旋转。
A four-stroke engine is an internal combustion engine variant in which the piston completes four strokes while turning a crankshaft. The mechanism here is different from that of two-stroke engines.
四冲程发动机是内燃机的变种，活塞在转动曲轴时完成四个冲程。这里的机制与二冲程发动机不同。
Although the six-stroke internal combustion engine is in its development phase, it’s already creating a lot of buzz in the motor industry. The six-stroke engine has several dedicated advantages over the traditional motors and may result in increased fuel efficiency, reduced mechanical complexity, and reduced emissions.
虽然六冲程内燃机还处于开发阶段，但它已经在汽车行业引起了很大的轰动。与传统发动机相比，六冲程发动机有几个专门的优势，可能会提高燃油效率，降低机械复杂性，并减少排放。

The main component of a reciprocating engine is a piston, which is used to convert pressure into rotating motion. There may be one or more pistons in an engine; each of them is located inside a cylinder. When pressurized gas is injected and heated inside the cylinder, the piston(s) initiate reciprocating or to and fro motion. This motion is converted into rotary motion with the help of a crankshaft.
往复式发动机的主要部件是活塞，它用来将压力转化为旋转运动。发动机中可能有一个或多个活塞;每一个都位于一个圆柱体内。当注入加压气体并在气缸内加热时，活塞开始往复运动或来回运动。这种运动在曲轴的帮助下转化为旋转运动。
The Wankel engine is also known as a rotor engine because it uses an eccentric rotary system (instead of a piston) to convert pressure into rotating motion. It is simpler, smoother, and much more compact compared to its more popular competitor, reciprocating or piston engine.
汪克尔发动机也称为转子发动机，因为它使用偏心旋转系统(而不是活塞)将压力转化为旋转运动。与其更受欢迎的竞争对手往复式或活塞式发动机相比，它更简单、更平稳、更紧凑。
In a compression ignition engine, the combustion of fuel in the chamber is triggered by the high temperatures achieved by gas or air due to adiabatic compression. Diesel engines are a perfect example of a compression ignition engine since it works only by compressing the air.
在压燃式发动机中，燃料在燃烧室中的燃烧是由气体或空气由于绝热压缩而达到的高温引发的。柴油发动机是压燃式发动机的一个完美例子，因为它只通过压缩空气来工作。
All petrol engines are based on spark ignition, where a spark plug ignites the combustion of the air-fuel mixture. Even though spark-ignition engines are commonly referred to as “petrol engines,” they can also run on autogas (LPG), methanol, bioethanol, compressed natural gas (CNG), hydrogen, and nitromethane.
所有汽油发动机都是基于火花点火，火花塞点燃空气燃料混合物的燃烧。尽管火花点火发动机通常被称为“汽油发动机”，但它们也可以使用天然气(LPG)、甲醇、生物乙醇、压缩天然气(CNG)、氢气和硝基甲烷。
Unlike traditional ICE-powered cars, electric cars get power from their pre-installed rechargeable batteries. These batteries not only power the engine, but other electrical equipment too. An electric motor simply converts electrical energy into mechanical energy.
与传统的内燃机动力汽车不同，电动汽车的动力来自预先安装的充电电池。这些电池不仅为发动机提供动力，也为其他电气设备提供动力。电动机只是把电能转换成机械能。
HCCI, or Homogeneous charge compression engine, is a revolutionary step towards minimizing emissions and maximizing fuel efficiency. The HCCI technology combines characteristics of conventional gasoline engines and diesel engines to produce a hybrid solution.
均质压燃，或均质充气压缩发动机，是朝着最小化排放和最大化燃油效率迈出的革命性一步。均质压燃技术结合了传统汽油发动机和柴油发动机的特点，产生了一种混合动力解决方案。

多缸发动机与单缸发动机正好相反：发动机有多个气缸，而不是一个气缸。它可以是二冲程或四冲程发动机，既可以是柴油发动机，也可以是火花点火发动机。

What does it mean when someone says it’s an inline engine? Well, it is just an alignment or the shape of cylinders. In inline engines, cylinders are arranged in a straight line — one behind the other — along with the length of the crankshaft.
有人说是直列发动机是什么意思？嗯，这只是一个排列或圆柱体的形状。在直列发动机中，气缸沿着曲轴的长度成直线排列，一个接一个。
The cylinders and pistons in a V-type engine are aligned in two separate planes, in such a way that they appear to be in a “V” shape when viewed from the top. The unique shape of this engine substantially reduces the overall engine weight and length compared to inline engines.
V型发动机中的气缸和活塞排列在两个独立的平面上，这样，从顶部看，它们呈“V”形。与直列发动机相比，这款发动机的独特外形大大降低了发动机的整体重量和长度。

The W engine first came into existence in 1909, when the Anzani three-bank engine powered the Blériot XI aircraft to cross the English channel. However, the first commercial use of this engine in the automotive industry was achieved by Volkswagen. The W (or double V) shaped engine has three different configurations which are as follows:
W 发动机首次出现是在1909年，当时安扎尼的三排发动机驱动布莱里奥11飞机穿越英吉利海峡。然而，这种发动机在汽车工业中的首次商业应用是由大众汽车实现的。W 型(或双 V 型)发动机有三种不同的配置如下:
An OPOC engine consists of two cylinders with a piston at both ends. There is no cylinder head, and thus no valves. Compared to conventional engines, the opposed cylinder opposed-piston engine has very low bearing loads, meaning there will be less friction. And since it is quite small in size, it has a high power to weight ratio.
对置活塞对置气缸发动机由两个气缸组成，两端各有一个活塞。没有气缸盖，因此没有阀门。与传统发动机相比，对置气缸对置活塞发动机的轴承负荷非常低，这意味着摩擦更少。由于它的体积很小，所以它具有很高的功率重量比。
Naturally aspirated engine is a type of ICE in which air intake depends solely on atmospheric pressure and does not rely on forced induction through a turbocharger or a supercharger. Many sports cars specifically use naturally aspirated engines to avoid turbo lag. Most automobile petrol engines, as well as many small engines used for non-automotive purposes, are naturally aspirated.
自然吸气式发动机是内燃机的一种，它的进气完全取决于大气压力，不依赖涡轮增压器或增压器的强制诱导。许多跑车专门使用自然吸气发动机，以避免涡轮滞后。大多数汽车汽油发动机，以及许多用于非汽车用途的小型发动机，都是自然吸气的。

Internal Combustion Engine
An internal combustion engine (ICE) is a type of heat engine where the combustion of fuel takes place inside the chamber. When the fuel burns inside the engine, it causes the temperature and the pressure to increase. This high pressure produced by combustion is then applied directly to power pistons, rotors, or a nozzle.
内燃机
内燃机是一种热机，燃料在燃烧室内燃烧。当燃油在发动机内燃烧时，会导致温度和压力升高。燃烧产生的高压直接作用于动力活塞、转子或喷嘴。

Moreover, Turbochargers are equipped with smog altering instruments that lower the carbon emission, so they are more eco-friendly than superchargers.
