The History of the Automobile Engine.

The automobile engine has undergone a long and

fascinating evolution since its humble beginnings in the

late 19th century. The first internal combustion engines

were developed in the 1860s and 1870s, and by the early

1890s, they were being used to power the first automobiles.

These early engines were crude and inefficient, but they

laid the foundation for the development of the more

sophisticated and powerful engines that would power the

automobiles of the 20th century.

In the early decades of the 20th century, the

automobile engine underwent a number of significant

developments. The first mass-produced automobile, the Ford

Model T, was introduced in 1908, and it featured a simple

and reliable four-cylinder engine. Other automakers

followed suit, and by the 1920s, four-cylinder engines had

become the standard for most passenger cars.

In the 1930s, the development of the overhead valve

(OHV) engine led to a significant increase in power and

efficiency. OHV engines use a camshaft located in the

cylinder head to operate the valves, which allows for

better valve timing and more efficient combustion. The OHV

engine quickly became the standard for most automotive

applications, and it remains the most common type of engine

in use today.

In the 1950s and 1960s, the development of the

electronic fuel injection (EFI) system led to further

improvements in power, efficiency, and emissions. EFI

systems use a computer to control the amount of fuel that

is injected into the engine, which allows for more precise

control of the combustion process. This results in better

fuel economy, lower emissions, and more power.

In the 1970s and 1980s, the development of the

catalytic converter led to a significant reduction in

emissions from gasoline-powered engines. Catalytic

converters use a chemical reaction to convert harmful

pollutants, such as hydrocarbons and carbon monoxide, into

less harmful substances, such as water and carbon dioxide.

The catalytic converter has become an essential part of the

emissions control system for all gasoline-powered vehicles.

In the 1990s and 2000s, the development of the

turbocharger and the supercharger led to further increases

in power and efficiency. Turbochargers and superchargers

use a compressor to force more air into the engine, which

allows for more fuel to be burned and more power to be

produced. Turbochargers and superchargers are now common on

many high-performance and luxury vehicles.

In the 21st century, the development of the hybrid

electric vehicle (HEV) and the electric vehicle (EV) has

led to a new era of automotive propulsion. HEVs use both a

gasoline engine and an electric motor to power the vehicle,

which improves fuel economy and reduces emissions. EVs use

only an electric motor to power the vehicle, which

eliminates emissions entirely. HEVs and EVs are becoming

increasingly popular as concerns about fuel economy and

emissions rise.

汽车发动机的发展历史。

汽车发动机自19世纪末诞生以来经历了漫长而迷人的演变。第

一个内燃机产生于19世纪60至70年代，到了19世纪90年代初，

它们被用来为第一批汽车提供动力。这些早期的发动机粗糙而效率

低下，但它们为20世纪将为汽车提供动力的更先进、更强大的发动

机的开发奠定了基础。

在20世纪的前几十年里，汽车发动机经历了几次重大发展。第

一款量产汽车——福特T型车于1908年推出，它搭载了一台简单而

可靠的四缸发动机。其他汽车制造商紧随其后，到20世纪20年代，

四缸发动机已成为大多数乘用车的标准配置。

20世纪30年代，顶置气门（OHV）发动机的开发极大地提高了

动力和效率。OHV发动机使用位于缸盖中的凸轮轴来操作气门，这

允许更好的气门正时和更有效的燃烧。OHV发动机迅速成为大多数

汽车应用的标准，并且仍然是当今最常见的发动机类型。

在20世纪50和60年代，电子燃油喷射（EFI）系统的发展进

一步提高了动力、效率和排放。EFI系统使用计算机控制喷射到发

动机的燃料量，从而可以更精确地控制燃烧过程。这带来了更好的

燃油经济性、更低的排放和更大的动力。

在20世纪70和80年代，催化转换器的开发极大地减少了汽油

发动机的排放。催化转化器利用化学反应将有害污染物（如碳氢化

合物和一氧化碳）转化为危害性较小的物质，如水和二氧化碳。催

化转化器已成为所有汽油动力汽车排放控制系统的重要组成部分。

在20世纪90年代和21世纪初，涡轮增压器和机械增压器的开

发进一步提高了动力和效率。涡轮增压器和机械增压器使用压缩机

将更多空气压入发动机，这允许燃烧更多燃料并产生更多动力。涡

轮增压器和机械增压器现在通常用于许多高性能和豪华车型。

21世纪，混合动力电动汽车（HEV）和电动汽车（EV）的发展

开启了汽车推进的新时代。混合动力汽车使用汽油发动机和电动机

为汽车提供动力，从而提高了燃油经济性并减少了排放。电动汽车

仅使用电动机为汽车提供动力，完全消除了排放。随着人们对燃油

经济性和排放的担忧加剧，混合动力汽车和电动汽车正变得越来越

受欢迎。
