Q.3. What are the main components of IC engine?
Answer
The principal structural and moving components of an IC engine include the Engine Cylinder, Piston, Connecting Rod, and Crankshaft.
- 1. Engine Cylinder & Block: The rigid main body where the high-pressure combustion of the air-fuel mixture physically occurs.
- 2. Piston: A close-fitting cylindrical plunger that reciprocates inside the cylinder, absorbing the massive expansive force of the combusting gases.
- 3. Connecting Rod: The vital linkage that mechanically transfers the linear thrust from the piston to the crankshaft.
- 4. Crankshaft: The main rotating shaft that continuously converts the reciprocating (up-and-down) motion of the piston into usable rotary torque.
