: The piston moves back and forth (reciprocating motion) within the cylinder. Piston rings ensure a tight seal to prevent gas leakage and manage lubrication.

: The camshaft operates the intake and exhaust valves , which regulate the flow of fresh air/fuel into the cylinder and the release of burnt gases. Introduction to Internal Combustion Engines

Internal combustion (IC) engines are heat engines where fuel burns with an oxidizer (usually air) inside a confined combustion chamber. This chemical process releases high-temperature, high-pressure gases that apply direct force to engine components, converting chemical energy into mechanical work. 1. Core Mechanical Components : The piston moves back and forth (reciprocating

: The connecting rod links the piston to the crankshaft . Together, they transform the piston's linear "up and down" movement into the rotational force that turns wheels. Internal combustion (IC) engines are heat engines where

: The cylinder block is the main structural support, housing the cylinders where pistons move. The cylinder head sits on top, containing the valves and ignition components.

An IC engine is built from a mix of stationary and moving parts that work together to produce power.
