Abstract: An intake and exhaust system for use with internal combustion engines that uses two intake valves and one exhaust valve for each engine cylinder. The three valves are preferably circular and spaced around the cylinder centerline in said cylinder head. One or more spark plugs (or other suitable ignition devices) are provided in the head on the cylinder centerline and/or between pairs of adjacent valves. For best results, the two intake valves have substantially equal diameters. Preferably, the ratio of exhaust valve diameter to intake valve diameter is from about 0.95:1 to 1:1.2. The head typically has three substantially hemispheric depressions each housing one of said valves. Squish areas are preferably provided around said combustion chamber periphery. The piston surface may be at least partially planar and may have an angled or radiused periphery or may have a central recess corresponding generally to the valve region. This invention provides a fast and uniform lean burn, permits use of a high compression ratio and lower octane unleaded gasoline and provides improved thermal efficiency. Other fuels and other fuel ignition systems also benefit, such as diesel engines.

Abstract: A system for introducing fuel into the combustion chamber of an internal combustion engine which includes at least one piston reciprocating in a cylinder with a cylinder head closing the top of the cylinder forming a combustion chamber between piston and head. At least one intake valve and one exhaust valve are provided in the cylinder head. One or more fuel injectors communicate through the sidewall of each of the engine cylinders for injecting fuel during the piston intake stroke while the top of the piston is below the injection site. The fuel injector may be any suitable injector, typically of a low pressure type. The fuel injector is oriented to direct a spray of fuel droplets in the direction of the cylinder head and/or the closed exhaust valve to speed droplet evaporation and cool the exhaust valve. Engines using this system also have increased tolerance of low octane fuel and improved emission characteristics.

Abstract: An improved Roots type supercharger for use with high performance vehicle engines. The supercharger includes rotors within a casing having rotor lobes with raised apex lands that move in a sealing relationship to the casing inside wall and rotor ends that move in a sealing relationship to the inside wall of casing end plates. A plurality of grooves are formed in at least one of the land, rotor end and end plate inside wall to reduce leakage of gases through those seals. The grooves are preferably formed generally perpendicular to the path of gas leakage through the seal.

Abstract: An intake and exhaust system for use with internal combustion engines that uses two intake valves and one exhaust valve for each engine cylinder. The three valves are preferably round and spaced substantially uniformly in the cylinder head around the cylinder centerline. For best results, the two intake valves have substantially equal diameters, with the diameter of the exhaust valve having a ratio to the diameter of an intake valve of from about 1:1 to about 1:1.2. Preferably one axial, three peripheral or an axial and three peripheral spark plugs equally spaced around the cylinder axis each centrally located in one of the areas between adjacent valves and the edge of the cylinder. The head has three substantially hemispheric depressions each housing one of said valves. This invention provides a fast and uniform lean burn, permits use of a high compression ratio and lower octane, unleaded gasoline and provides improved thermal efficiency.

Abstract: An improved multi-cylinder engine exhaust header and single exhaust pipe transition element. The transition element comprises separate cylinder exhaust input connections, a gas chamber, a single exhaust gas output and a thin blade member positioned between at least two separate exhaust input connections. The forward end surface of the blade member takes various configurations to aid the mixing of the exhaust gases from each separate cylinder in the gas chamber prior to exit from the exhaust gas output.

Abstract: A muffler for use with internal combustion engines or the like having improved sound attenuation capabilities together with lower back pressure. The muffler has an elongated outer casing connected to inlet and outlet pipes by inlet and outlet transition sections. A central diffuser body is located within the outer casing substantially along the longitudinal centerline thereof. Mounting plates connect the front and rear ends of the diffuser body to the inlet and outlet pipes, respectively, to hold the diffuser body in place. An inner casing is spaced from, and conforms to, the inner surface of said outer casing between transition sections. The inner casing and the side wall of the diffuser body are perforated. Porous or fibrous sound absorbing material is contained within the diffuser body and between the inner and outer casings. The cross-sectional areas of the inlet pipe and the ring between the inner casing and the diffuser body are preferably substantially equal.
