Text learning-example Project 1 Introduction to the construction and operation of a Four-stroke Engine The engine assembly The engine is the source of power that provides the torque or turning force which is used to drive the vehicle. Engines in motor vehicles can be internal combustion, electric or a combination of the two (known as hybrid). Internal combustion engines burn the fuel inside the engine using petrol, distillate or gas. Electric motors use electricity supplied from storage batteries fitted to the vehicle. The batteries can be charged using an internal combustion engine, fuel cell, solar cell, power regeneration and external charging. The engine assembly includes the engine itself as well as all the components and systems needed to make it start and run. These include the starting, charging, cooling, ignition, lubrication, fuel and the exhaust systems (shown as Figure 1-1). 项目一 四冲程发动机构造与工作过程介绍 Brief Introduction Word List Word List Word List Components cognition Components cognition Components cognition Components cognition Components cognition Components cognition Components cognition Components cognition Components cognition Proper Names Proper Names Proper Names Translation of difficult sentence 1.
