2.1. 能源与动力

能源是用于生产电力。化工能源转化为燃料的燃烧的热量，这个过程被称为燃烧。如果发动机燃烧发生在汽缸内的地方，被称为发动机内部燃烧发动机。如果燃烧发生在汽缸外的地方，被称为发动机外部燃烧发动机。

用于汽车的能源叫内部燃烧高能源高温能源在燃烧室里降低能缓解气体燃烧在汽缸室里的温度。燃烧气体温度的升高引起气压变大。燃烧室内发展应用到了活塞产生一个可用的机械力，然后将其转换成有用的机械能。

2.1.2发动机条款

通过曲轴连杆连接活塞,造成气体轴旋转半转。动力冲程“使用了”气压，意味着必须提供手段驱逐燃烧气体和回灌用新鲜的汽油和空气混合气体钢瓶：这种气体的运动控制是阀门的责任;一进气阀使新进入的混合物在适当的时间和一排气阀让燃烧后的气体在已完成了它的工作任务后排出，。发动机条款（图2-1）：

TDC（上止点）：曲轴对应活塞的位置时，活塞远离曲轴。

BDC（下死点）：曲轴对应活塞的位置时，活塞最接近曲轴。

行程：下死点和上止点之间的距离;中风是由曲轴，行程是由曲轴控制。

缸径：圆柱的内部直径。

波及体积：下死点和上止点之间的音量。

发动机排量：这是所有的气缸容积，例如四汽缸发动机，有

1. principle of operation 原理

Engine and power :

Engine is used to produce power. The chemical energy in fuel is converted to heat by the burning of the fuel at a controlled rate. This process is called combustion. If engine combustion occurs with the power chamber. ,the engine is called internal combustion engine. If combustion takes place outside the cylinder, the engine is called an external combustion engine.

UNIT 2 AUTOMOTIVE ENGINE

2.1 Purpose and Locations of Engines

The purpose of an automotive engine is to supply the power needed to move the vehicle. The engine produces this power by burning fuel inside it. Because the engine burns fuel inside, or internally, the engine is known as an internal combustion engine（ICE）.

汽车发动机的功用是汽车行驶提供必需的动力。发动机通过它内部的燃料燃烧来产生动力。由于发动机在其内部燃烧燃料，所以发动机被称作内燃机。

Engines may be fueled by gasoline, propane （LPG-liquefied petroleum gas） , or diesel fuel. Compressed natural gas （CNG） may also be used in some
