A single piston in an engine works with a cylinder.
The number of valves depend on the design and configuration of engine.
Some engines have two valves (one for intake and one for exhaust) and some have four valves (two for intake and two for exhaust).
Intake Valves allow the fuel and air mixture in the cylinder.
Exhaust valves exit the gases from cylinder after combustion.
