    摘要: A catalytic prereaction timing ignition method and igniter unit for timed ignition of a fuel-air mixture in internal combustion engines providing an ignition chamber open into the combustion chamber of the engine, there being a catalytic ignited positioned in the ignition chamber to intercept a pressure front of stratified fuel-air mixture penetrating a prechamber timing zone of the ignition chamber and controlled by the spring rate of burnt gases captured in a buffer zone of the ignition chamber during the compression cycle and ignited by the pressure front touching the igniter to effect the power stroke of the engine.

    摘要: An internal combustion engine comprises a body (6) defining a cylinder (8), within which a piston (10) is mounted, and a cylinder head (12) secured to the body (6) over the cylinder (8), a chamber (16) being provided between the body and cylinder head within which a rotary valve member or rotor (18) is mounted for rotation in bearings (19). The rotor provides inlet ports (20) and exhaust ports (22) which are sequentially brought into communication with the cylinder to deliver a combustible fluid to the cylinder wherein the combustible fluid is ignited, and to exhaust gases from the cylinder. The rotor (18) is provided with a supplementary chamber (70) which is periodically brought into communication with the engine cylinder, and ignition means (72,74,75) which is operative to ignite combustible fluid in the supplementary chamber (70). Conveniently combustible fluid is delivered to the supplementary chamber (70) from the engine cylinder (8) prior to operation of the ignition means, but may be supplied to the supplementary chamber (70) by separate injection means (78). The rotor (18) comprises cooling means (33,35,36) through which cooling fluid is caused to flow during rotation of the rotor, to reduce the temperature of the rotor in operation. Sealing means (46 or 142 or 154) is provided which is operative between the opening into the engine cylinder and the circumferential surface (26) of the rotor to reduce the escape of gases from the cylinder.

    摘要: An spark-ignition internal combustion engine (1) is equipped with a gas feeding system (2), comprising a plurality of main gas injectors (19) each associated with an intake duct (4) of a respective cylinder (3) of the engine, a gas distribution manifold (18) communicating with said main gas injectors (19), a gas tank (16), connected to the distribution manifold (18), where gas under pressure is accumulated, an electronically-controlled pressure regulation valve (20), which is interposed in the connection (17) between the tank (16) and the aforesaid distribution manifold (18), and an electronic control unit (E) configured to control the pressure regulation valve (20) in order to establish a gas pressure in the aforesaid gas distribution manifold (18), which is determined according to the operating conditions of the gas feeding system (2) and according to the operating conditions of the engine (1). The spark plug (24) of each cylinder is mounted within a support body (25) that defines a combustion pre-chamber (30) and a channel (31) for auxiliary gas injection within the combustion pre-chamber (30), communicating with a respective auxiliary gas injector (36) mounted on the cylinder head in a remote position relative to said combustion pre-chamber (30). The auxiliary gas injectors (36) are all in communication with the gas distribution manifold (18), downstream of the pressure regulation valve. In the channel (31) for the auxiliary injection of gas, a non-return valve (33) and a restricted passage (32A) are provided in series, allowing passage of a gas flow proportional to the volume of the combustion pre-chamber (30).
