    Let's look at your choices and it becomes easy to tell which is the answer: Intake is when the fuel is brought into the chamber. Compression is the fuel being compressed within the chamber by the piston Power is the combustion of the fuel pushing the piston back up Exhaust is the releasing of the gases from the chamber Which of these provides some kind of force? Find that and you have your answer.
