Work of a ENGINE
A engine is the
central part of a vehicle it’s help the vehicle to do its work. Here I
describe about 4stroke engine…
Four stroke
engine….
Component:-
1:-piston.
2:-cylinder.
3:-spark plug.
4:-valves.
5:-crank shaft.
7:-champ shaft.
Work
process:-
(1) SUCTION:- It is the first stroke of a 4stroke engine. In this stroke the piston is goes down and it create a vacuum at that that time the inlet valve is open, as the piston goes down ward it create a vacuum , so to fill it fuel is come into the cylinder. Then the engine is goes for second stroke i.e compression.

(3) Power:- It is the most important
stroke, the whole power of the engine is depend on this stroke. In this
stroke the compressed fuel which is in
high temp. & pressure, is burn when the spark is happen in the sparkplug. As
the high pressure fuel burn it expand rapidly and it puss the piston to
downward. After this stroke the engine run continusly.
(4) Exhaust:- This is the last stroke of
the total process, after the power stroke due to inertia the piston goes up, at
the same time the outlet valves is open and the burned fuel is Exhausted to
outside.
As this the all four stroke is completed and
this process is continue till the engine is running.
