internal combustion engine theory

An internal combustion engine converts fuel into energy through controlled explosions inside cylinders. Fuel mixes with air and is ignited by a spark, causing a small explosion that forces a piston to move. This movement turns a crankshaft, ultimately powering a vehicle or machine. The engine cycles through intake (air and fuel intake), compression (pushing the mixture together), power (explosion), and exhaust (expelling gases). This continuous cycle transforms chemical energy from fuel into mechanical energy, providing the power necessary for motion, making internal combustion engines a common propulsion method in cars and many machines.
