A four stroke combustion engine and method of operation of use and control i s disclosed. The engine includes a combustion chamber with an intake manifold coupled to the combustion chamber. A one-way valve (22) is located within th e intake manifold. The engine includes an intake valve (10) for modulating the flow of a fuel-air mixture into and out of the combustion chamber. The engin e preferably employs a fixed, late closing intake valve. A plenum chamber (20) is located in the intake manifold. The plenum chamber is located downstream of the one-way valve and upstream of the intake valve. During the compression stroke of the engine, a pressurized charge of fuel-air mixture is stored within the manifold and plenum. The amount of the fuel-air mixture stored within the plenum is controlled by adjusting the volume of the plenum, or, alternatively, a plenum valve (34) is used to regulate the amount of fuel-ai r mixture entering/exiting a fixed volume plenum.
