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).
internally [ in'tənəli ] 在内(部)
internal combustion engine 内燃机，内燃机引擎|引擎
internal combustion engine oil 内燃机油
Engines may be fueled by gasoline, propane ( LPG-liquefied
petroleum gas) , or diesel fuel. Compressed natural gas(CNG)
may also be used in some vehicles.

Most automotive engines are located at the front of the
vehicle. Many engines drive the rear wheels. This requires a
long
drive shaft
extending form the front wheels
to the rear
wheels. Other engines drive the front wheels. In the
rear-wheel-drive arrangement, the engine sits longitudinally.
Its long dimension is from front to back.

In the front-wheel-drive arrangement, the engine sits
crosswise, transversely. With either arrangement, the power is
carried to the drive wheels (rear or front)by gears and shafts.
