14 Parts Of The Engine - Parts of engine cars - Parts of Engine Block Motor Cycle - Diesel Petrol

Engines

Engine is a machine which converts chemical energy into mechanical energy to done some work.

Here chemical energy means energy which is produced by combustion of fuel like gas, petrol, diesel or etc..

Two types of engines are:

I.C. Engines & E.C. Engines

Classification of engine

Now days engines are used in many vehicles which are suppose to petrol, diesel or etc

To carry out that type of usage there are wide range of engines due to its output capacity or power.

So, let us learn about engine

The main parts of the engine are shown as below.

1. Cylinder 

Cylinder is the main part of the engine. Energy is produced inside the cylinder by combustion of fuel. The inside part of the engine is known as bore. During combustion of fuel there are high temperature and high pressure so this part of engine must be cool. So the power is developed in the cylinder. To prevent from the wear it gets tight sleeve inside the cylinder.

2. Cylinder head

 As the name suggests cylinder head is the cover of the cylinder it provides space for Valve mechanism, injector and spark plug.

3. Spark plug

Spark plug is placed in the cylinder head. Which is used for spark air and fuel mixture with high intensity in petrol engines?

4. Fuel injector 

Fuel injector is used to spray diesel under high pressure at the end of compression stroke. Fuel injector is only used in diesel engines. 

5. Piston

The piston is cylindrical plunger reciprocating inside cylinder .piston plunge continues when engine is running by pressure of combustion fuel. Piston is connected to connecting road to the crank. Piston rings are provided on the piston.

6. Piston rings

Piston rings are provided on piston to gas tight joint between piston and cylinder. Piston rings are arranged for make engine more optimize 

7. Connecting road 

The main work of the connected road is to convert reciprocating motion of piston into rotational motion which is connection between piston and crank?

8. Crank

Crank is a mechanism which moves in rotational motion by connecting connected road and crank shaft.

9. Crank shaft

Crank shaft is rotating by pressure of combustion of fuel which is transmitted over connected road and then cranks which is directly connected to crank shaft. Crank is rotating about axis of the crank shaft. 

10. Valves

Valves are the mechanism for control both intake and exhaust of the gases from the cylinder. Both valves are controlled by valve operating mechanisms.

11. Flywheel

It is mounted on the crank shaft of the engine. It optimizes cyclic variations. 

12. Fuel pump

Which is directly connected to the injector for providing and controlling the quantity of diesel with more pressure to inject in cylinder? Which is used in only diesel engines?

13. Carburetor

Carburetor is used in petrol engines to making required mixture of petrol and air.

14. Crankcase

Crankcase is serving as enclosure of the crank shaft.
