WHAT IS ENGINE AND HOW MANY TYPES OF ENGINE ?
WHAT IS ENGINE ?
Engine is a mechanical device that converts chemical energy to mechanical energy to produce heat energy.
Today we will discuss about engine and types of engine used in automobile. Any device which can convert heat energy of fuel into mechanical energy is known as engine or heat engine. Engine is widely used in automobile industries or we can say that engine is the heart of an automobile. Basically engine may be classified into two types.

Types of engine?
External combustion (E.C.) Engine
An engine in which combustion of fuel take place outside of the cylinder is known as EC engine. In this type of engine heat, which is generated by burning of fuel is used to convert the water or other low boiling temperature fluid into steam. This high pressure steam used to rotate a turbine. In this engine we can use all solid, liquid and gases fuel. These engines are generally used in driving locomotive, ships, generation of electric power etc.
Advantages of E.C. engine-
- In these engines starting torque is generally high.
- Because of external combustion we can use cheaper fuels as well as solid fuel.
- They are more flexible compare to internal combustion engines.
2. Internal Combustion (I.C.) Engine
It is an engine in which combustion of fuel take place inside the engine. When the fuel burns inside the engine cylinder, it generates a high temperature and pressure. This high pressure force is exerted on the piston (A device which free to moves inside the cylinder and transmit the pressure force to crank by use of connecting rod), which used to rotate the wheels of vehicle. In these engines we can use only gases and high volatile fuel like petrol, diesel. These engines are generally used in automobile industries, generation of electric power etc.
