  • Patent number: 5377630
    Abstract: A multicylinder two-stroke cycle internal combustion engine (10) comprises an individual crankcase cavity (18) for each cylinder to receive the incoming air charge for that cylinder and a cylinder block (11) with at least two cylinders having cooperating crankcase cavities (18) provided with valve controlled intake ports (19) in a common wall (31) of the cylinder block (11). An air induction manifold (25) is detachably mounted to the common wall (31) to form a single air induction cavity (27), at least part of which is formed within the cylinder block (11), and has a single main inlet port for regulation of air inflow to the induction cavity (27). Individual passages (33) communicating each crankcase cavity inlet port (19) with the air induction cavity (27) are formed in the manifold (25). Acceptable performance with limited increase in the overall physical dimensions of the engine (10) can thus be obtained.

  • Patent number: 4924820
    Abstract: A two-stroke spark ignited engine (10) with direct fuel injection (14) and an exhaust gas treatment catalyst. A separate catalyst unit (23) is provided for each combustion chamber (11) and is located at or adjacent each exhaust port (15) from that chamber and that during a cycle of each combustion chamber (11) the catalyst unit (23) of that combustion chamber (11) is exposed only to exhaust gases which change from chemically reducing to chemically oxidizing during the cycle. An engine which has exhaust gases which are overall chemically oxidizing can thus nevertheless have the NOx constituents of the gases reduced.

  • Patent number: 4886021
    Abstract: A multi-cylinder engine block for an engine operating on the two-stroke cycle and having two or more adjacent cylinder bores (10,11,12) with the axes of the bores parallel and in a common longitudinal plane. Each cylinder bore having an exhaust port (20), and an exhaust passage (21) extending from each exhaust port (20) to an external surface (22) of the block in a direction generally at right angles to said common longitudinal plane (25). Two transfer ports (27,28) being provided communicating with the same cylinder bore on either side of the exhaust port in the direction of said common longitudinal plane. Each transfer port communicating with a respective transfer passage. The transfer ports (27,28) not extending beyond the common longitudinal plane (25), and the transfer passages (26,23) adjacent the respective transfer ports (27,28) extending in a direction generally tangential to the cylinder bore.

  • Patent number: 4781164
    Abstract: A method of fuel injection for an internal combustion engine having one or more combustion chambers and wherein a metered individual quantity of fuel entrained in a gas charge is injected individually by the pressure of the gas directly into each combustion chamber each combustion cycle thereof. The method including the steps of delivering gas from at least one combustion chamber of the engine to a common gas reservoir, and controlling said delivery of gas to the gas reservoir to substantially maintain the gas therein at a pressure above the maximum compression pressure in the combustion chamber prior to commencement of combustion in said combustion chamber. Supplying gas at a regulated pressure from said gas reservoir to receive the metered quantity of fuel and effect in sequence delivery of that fuel into the respective combustion chambers of the engine.
