This illustration showcases an Otto Cycle Engine. The Otto cycle is a thermodynamic cycle that describes the functioning of a typical spark-ignition internal combustion engine, like those found in most gasoline-powered cars. It consists of four key processes that occur in a piston-cylinder arrangement.
1️⃣ Intake Stroke – The intake valve opens, and the piston moves downward, drawing in a fuel-air mixture.
2️⃣ Compression Stroke – The piston moves up, compressing the fuel-air mixture to increase its energy potential.
3️⃣ Power Stroke (Combustion) – A spark ignites the compressed mixture, causing an explosion that pushes the piston down. This is where the engine generates power.
4️⃣ Exhaust Stroke – The piston moves up again, expelling the burnt gases through the exhaust valve.
This cycle repeats rapidly, providing continuous power output.
