The Otto cycle is a thermodynamic cycle that describes the functioning of a typical gasoline engine. It consists of four main processes: intake, compression, power, and exhaust. During the intake phase, a mixture of air and fuel enters the cylinder. The piston then compresses this mixture, raising its temperature and pressure before ignition occurs. After ignition, the combustion of the fuel-air mixture generates high pressure, pushing the piston down and producing power. Finally, the exhaust phase expels the burnt gases from the cylinder, allowing the cycle to repeat. This efficient process is fundamental to many modern vehicles.
