Abstract:
An improved combustion chamber system for use with internal combustion engine having at least one piston and a cooperating cylinder head area forming a single combustion chamber therebetween, which comprises:three valves in said head area at said combustion chamber;first and second said valves positioned to act simultaneously as intake valves;a third of said valves being positioned to act as an exhaust valve;the ratio of total exhaust valve cross sectional area to total intake valve cross sectional area being in the range of about 45% to 65%;said combustion chamber system providing an exhaust gas velocity higher than inlet gas velocity;said piston slidably positioned in a bore having a predetermined cross sectional area and having a face adjacent to said head area forming one wall of said combustion chamber;said piston face having three cooperating squish areas located along the piston face periphery and extending between adjacent valves;said piston face having a substantially planar raised central area surrounded by an angled periphery so that said squish areas are angled relative to said planar raised central area;at least one ignition means for igniting an air/fuel mixture in said combustion chamber.
