PURPOSE AND FUNCTION:
The purpose and function of an engine is to convert the heat energy of burning fuel into mechanical energy. In a typical vehicle, mechanical energy is then used to perform the following:
- Propel the vehicle
- Power the air-conditioning system and power steering
- Produce electrical power for use throughout the vehicle
ENERGY AND POWER :
Engines use energy to produce power. The chemical energy in fuel is converted to heat energy by the burning of the fuel at a con trolled rate. This process is called combustion. If engine combustion occurs within the power chamber, the engine is called an internal
combustion engine.
Engines used in automobiles are internal combustion heat engines.They convert the chemical energy of the gasoline into heat within a power chamber that is called a combustion chamber. Heat energy released in the combustion chamber raises the temperature of the combustion gases within the chamber. The increase in gas
temperature causes the pressure of the gases to increase. The pressure
developed within the combustion chamber is applied to the head of a piston to produce a usable mechanical force, which is then converted into useful mechanical power.
