A
Step-by-step explanation:
The fourth-stroke engine cycle is a kind of motor that performs four distinct thrusts while rotating a rotor. The first is the inlet, where the piston starts at the top did centre. The second stage is compression, which begins at bottom dead centre and involves the engine compressing the mixture with air in preparation for ignition. The third stage is ignition, which initiates the cycle's second revolution. Finally, the pistons return to The top dead center from Bottom did center during the exhaust.
