What happens to a intake and exhaust valve during the power stage cycle in a four cycle gas engine?

If im not mistaken, during the power stage the intake and exhaust valves are both closed. the intake valve opens pulling air into the cylinder (cycle one) and the exhaust valve opens (cycle 4) to relase the air fuel mix that was ignited.


What is the correct position of the intake and exhaust valves during most of the power stage in a four cycle gas engine?

During the power or combustion stage of a piston cycle, both valves are necessarily closed, because the expansion of gases is driving the piston down.

What correctly describes the position of the intake and exhaust valves during most of the power stage in a four cycle gas engine?

closedUpdated answer,Firstly the four stages of an "Otto Cycle Engine" are, Induction the intake valve is opening, to let fuel and air mixture into piston chamber. Compression the intake valve and exhaust are shut to compress fuel air mixture. Powerfuel air mixture ignited, both the intake and the exhaust valves are closed. And finally Exhaust when the exhaust valve is open to release spent gasses. At idle speed approximately 800 rpm it should be appreciated timing is important.
