Abstract:
1. An internal combustion engine comprising: 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 said air intake pressurization device outlet and from which exhaust gases are expelled; a plurality of fluid flow valves each having open and closed states relative to said combustion chamber and comprising at least first and second intake valves and one or more exhaust valves, said combustion chamber in periodic fluid communication with said air intake pressurization device outlet through at least one of said first and second intake valves, exhaust gases expelled from said combustion chamber via said exhaust valve(s); a control valve disposed between said first intake valve and said air intake pressurization device outlet, said control valve having an open position in which said air intake pressurization device outlet and said combustion chamber are in fluid communication via said first intake valve in its open state and a closed position in which fluid communication between said air intake pressurization device outlet and said combustion chamber via said first intake valve in its open state is comparatively restricted; said exhaust valve(s) in its open state when said first and second intake valves are both in their closed states, said first and second intake valves both in their open states when said exhaust valve(s) is in its said closed state, said second intake valve moved from its open state into its closed state substantially prior to movement of said first intake valve from its open state into its closed state; wherein said first and second intake valves open substantially simultaneously.
