A four-stroke engine, fundamental to modern automotive and industrial propulsion, operates on a cycle comprising four distinct strokes: intake, compression, power, and exhaust. During the intake stroke, the intake valve opens, allowing a mixture of fuel and air to enter the combustion chamber as the piston moves downward. The subsequent compression stroke sees the piston move upward, compressing the fuel-air mixture, which optimizes combustion efficiency. Ignition occurs at the top of the compre
