The document discusses the key components and workings of an internal combustion (IC) engine. It defines a cylinder as the central working part where a piston travels, and a connecting rod as connecting the piston to the crankshaft. The IC engine converts chemical energy from fuel into mechanical energy by igniting a fuel-air mixture in the combustion chamber, which then acts on the piston. Some advantages of IC engines over external combustion engines are that they are cheaper, have a higher power-to-weight ratio, and emissions can be minimized with advanced designs.

• A cylinder is the central working part of
a reciprocating engine or pump, the space in
which a pistontravels.

4. Parts of IC engine

5. Connecting Rod
• In a reciprocating pistonengine,the connecting
rod or conrod connects the piston to the crank or
crankshaft.

6. What is IC Engine
• The Internal Combustion (IC) Engine Converts
• Chemical Energy into useful mechanical
Energy by Burning the fuel
• Chemical Energy is released when the fuel –
air mixture is ignited by a spark in the
combustion chamber

7. Piston rings
A piston ring is a split ring that fits into a
groove on the outer diameter of a piston in a
reciprocating engine such as an internal
combustion engine or steam engine.

8. Piston
Piston
The piston of an internal combustion engine is
acted upon by the pressure of the expanding
combustion gases in the combustion
chamber space at the top of the cylinder.

• The advantages of the internal combustion
engine is that it is:
* Cheap
* High power to weight ratio
* It is possible to raise the efficiency to
relatively high levels by minor means
* Emissions are minimized by advanced
combustion control, design and
aftertreatment.
