7. How does a steam
engine work
A fire where the coal burns. A boiler full of water that the fire heats up to make
steam. A cylinder and piston, rather like a bicycle pump but much bigger. Steam
from the boiler is piped into the cylinder, causing the piston to move first one way
then the other.

9. How does a wankel
engine work
The engine works very similarly in principle to a piston-cylinder engine, with
intake, compression, combustion, and exhaust occurring within the combustion
chamber which is somewhat oval shaped. As the rotor spins around, it rotates the
eccentric shaft sending power to the transmission.

11. How does a diesel
engine work
The basic difference between a diesel engine and a gasoline engine is that in a
diesel engine, the fuel is sprayed into the combustion chambers through fuel
injector nozzles just when the air in each chamber has been placed under such
great pressure that it's hot enough to ignite the fuel spontaneously.

15. How does a internal
combustion engine
work
In a spark ignition engine, the fuel is mixed with air and then inducted into the
cylinder during the intake process. After the piston compresses the fuel-air
mixture, the spark ignites it, causing combustion. The expansion of the
combustion gases pushes the piston during the power stroke.

Combustion

17. How does a external
combustion engine
work
An external combustion engine burns fuel
externally, or outside the engine. An
external combustion engine burns fuel to
heat water and produce steam. The steam
is under pressure and is used to push a
piston back and forth inside a cylinder. As
the piston moves back and forth, it moves
a piston rod, which can do work.

18. Difference between
E.C and I.C
E.C Engine:
1. Two working fluid in this type of
engine.
2. Combustion of the fluid take
place out side the cylinder.
3. Large in size due to many
accessoties.
4. As we know that heat transfer
take place from one fluid to the
another so, heat losses in this
type of engine is more.
5. Example of such types of
engines are – steam
engine,steam turbine.
I.C Engine
1. One working fluid in this type of
engine.
2. C0mbustion of the fluid take
place in side the cylinder.
3. Small and simple in size as
compare to E.C engine.
4. In this type of engine no heat
transfer occurs, so the heat
losses are less.
5. Example of such types of
engines are – S.I. engine, CI
engine.
