An internal combustion engine including an air intake pressurization device having an outlet from which air at a pressure substantially greater than ambient air pressure is expelled, an expansible combustion chamber into which air is received from the device outlet and from which exhaust gases are expelled, first and second intake valves and one or more exhaust valves, each valve having open and closed states. The combustion chamber is in periodic fluid communication with the device outlet through at least one of the first and second intake valves, and exhaust gases are expelled from the combustion chamber via the exhaust valve(s). A control valve disposed between the first intake valve and the device outlet has an open position in which the device outlet and the combustion chamber are in fluid communication via the first intake valve in its open state, and a closed position in which fluid communication between the device outlet and the combustion chamber via the first intake valve is comparatively restricted. The exhaust valve(s) is in its open state when the first and second intake valves are both in their closed states, the first and second intake valves are both in their open states when the exhaust valve(s) is in its closed state, and the second intake valve is moved from its open state into its closed state substantially prior to movement of the first intake valve from its open state into its closed state.
