types of lubrication system in ic engines pdf

The stroke is the distance traveled by the piston inside the cylinder it is usually equal to the length of the cylinder. That means each time the fuel is burnt there are two rotations of the wheels of the vehicle. In the case of four-stroke engines, the fuel is burnt for every four strokes of the piston inside the cylinder. This means for every single rotation of the wheel the fuel is burnt. In the case of the two stroke engine, for every two strokes of the piston inside the cylinder the fuel is burnt. The SI and CI engines are either two stroke or four stroke engines. In CI engines the fuel used is diesel hence they are also called Diesel engines. The fuel is compressed to high pressures and it starts burning, hence these engines are called compression ignition engines. In the case of CI engines, burning of the fuel occurs because of the high pressure exerted on the fuel. In these engines the fuel used is petrol or gasoline, hence SI engines are also known as Petrol or Gasoline Engines. Due to this fact they are called spark ignition engines. In SI engines the burning of fuel occurs by a spark generated by the spark plug located in the cylinder head of engine. It is this reason that even the IC engines are broadly classified into two types: SI engines and CI engines. Since reciprocating engines are the most widely used engines, they have become synonymous with the name IC engines. Reciprocating engines are classified into two types: spark ignition (SI) engines and compression ignition (CI) engines. They are the most widely used type of engine. In automobiles, reciprocating engines are used. The reciprocating motion of the piston is converted into the rotary motion of the vehicle’s wheels. In the case of the reciprocating engines, a piston reciprocates within a cylinder. In rotary engines, a rotor rotates inside the engine to produce power. There are two types of IC engines: rotary and reciprocating engines. After combustion of fuel, much heat energy is generated, this is converted into mechanical energy. Internal Combustion Engines, more popularly known as IC engines, are the ones in which the combustion of fuel takes place inside the engine block itself.
