SPARK PLUG ( PETROLENGINE )
Electric match used to
begin the combustion
process of burning air
and gasoline to create
heat.

Piston- the part of the engine that moves up and
down in the cylinder converting the gasoline into
motion
Know Your Piston!
PistonRings:-
The rings seal the compression gases abovethe
piston keep the oil below the piston rings.
Piston
Pins:-
Also known as the
wrist pin, it connects
the piston to the
small end of the
connecting rod.
It transfers the force
and allows the rod to
swing back and forth.

Crankshaft- converts the up and down motion ofthe
piston into a turning, or rotatingmotion
Along the the piston
pin and connecting
rod it converts the up
and down motion
(reciprocating) of the
engine to spinning
(rotary) motion.

Flywheel
:-
Carries the inertia when there isno
power stroke.

GASKET
A gasket is a mechanical seal which fills the space
between two or more mating surfaces, generally to
prevent leakage from or into the joined objectswhile
under compression
WATER PUMP
The water pump is a simple centrifugal pump driven
by a belt connected to the crankshaft of the engine.
The pump circulates fluid whenever the engine
is running.
