2. INTRODUCTION
A two stroke or two cycle engine is a type of
internal combustion which completes a power
cycle with two strokes of the
Piston during only one crankshaft revolution.
This is in contrast to a for stroke engine which
requires four strokes of the piston to complete a
power cycle. In a two stroke engine the end of the
combustion stroke and the beginning of the
compression stroke happen simultaneously, with
the intake and exhaust functions occurring at the
same time.

4. DIESEL CYCLE
The Diesel cycle is a combustion process of
a reciprocating internal combustion engine
.In it ,fuel is ignited by heat generated
during the compression of air in the
combustion chamber , into which fuel is
then injected. This is in contrast to igniting
the fuel air mixture with a spark plug as in
the Otto cycle engine . Diesel engines are
used in aircraft automombiles power
generation diesel-electric locomotives and
both surface ships and submarines
Two stroke diesels with high pressure
forced induction particularly turbocharging,
make up a large percentage of the very
largest diesel engines

6. DISEL ENGINE WORKING:-
The two stroke diesel engine is an internal
combustion engion with the events common to all
such engines.
First is intake, when a blower forces air alone into
the cylinder.
Compression squeezing the air into a small volume
this is when fuel is sprayed into the chamber.
Power forcing the piston down.
Exhaust removing burned gases.
All in just two strokes. The whole process is a
cycle. Everything is back where it began ready to

8. PARTS:-
• INJECTER
• PISTON
• CONNECTING ROD
• INLET PORT
• EXHUST PORT
• TRANSPHER PORT

9. ADVANTAGE:-
 High engine speed of about 3000 rpm.
Lighter in a weight because maximum
pressure and temperature is less.
Less initial cost.
Less maintenance cost

10. DISADVANTAGISE:-
HIGH compression ratio ranging from
15 to 17.
The thermal efficiency is HIGHER due to
HIGHER compression ratio.
Running cost higher because petrol is
costlier.

11. APPLICATION:-
• AUTOMOBILE VEHICLE MOPED
• GENERATER
