    摘要： An engine control system is disclosed for reducing the hydrocarbon content in exhaust gas from a crankcase-scavenged, two-stroke engine (10) in the operating range near idle, with light operator-­induced engine loading. As operator demand for engine output power is increased, the control system increases the fuel per cylinder delivered to the engine (10), whilst restricting the supplied mass of air per cylinder to a value less than or equal to that flowing at unloaded engine idle, in said operating range. This is done by coupling a throttle pedal (56) to a throttle valve (52) in an air intake manifold (20) through a pivoted linkage system (60,62,64,66,68,70,72,74) which includes a lost-motion connection (72,74), which prevents movement of the throttle valve (52) until a predetermined displacement of the throttle pedal (56) has occurred. A computer (48) of the control system controls the fuel supply per cylinder in response to signals (PED) received from a potentiometer (84) monitoring all mobement of the throttle pedal (56). The control system also may include an air bypass passage (76) and a computer-controlled, solenoid-actuated valve (78) to further control the supplied mass of air in said operating range.

    摘要： A two-stroke engine comprises a cylinder (2) accommodating a piston (6) and having an air inlet port (18) and an exhaust port (14,16). The exhaust port (14,16) communicates with an exhaust system (25) which includes a reduction catalyst (R) and an oxidation catalyst (O). The exhaust system (25) includes two exhaust flow paths (24,26) in parallel, the first (24) of which includes the reduction catalyst (R) and the second of which bypasses the reduction catalyst (R), the downstream ends of the two flow paths (24,26) being connected together upstream of the oxidation catalyst (O). The exhaust port (14,16) is controlled by the piston (2) or by poppet valves (32,34) so that as the piston (6) performs its downstroke the initial flow of exhaust gas is substantially through the first flow path (24) and the subsequent flow of exhaust gas is substantially through the second flow path (26).

    摘要： A two-stroke spark ignited engine (10) with direct fuel injection (14) and an exhaust gas treatment catalyst. A sepa­ rate 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 oxidising during the cycle. An engine which has exhaust gases which are overall chemically oxidising can thus nevertheless have the NOx con­ stituents of the gases reduced.

    摘要： Un système de transfert de gaz assure une charge et un balayage unidirectionnels dans un moteur à combustion interne et à pistons alternatifs par induction et compression au carter. La culasse (L) est munie d'orifices d'admission (N) commandés par un piston et le cylindre (O) est muni d'orifices d'échappement (F). L'intérieur du piston forme le passage du carter (J) au cylindre (O), à travers la tête du piston. La tête est pourvue d'une extension (D) et d'orifices de transfert (A) qui interagissent de telle sorte avec les orifices d'admission (N) du cylindre que la charge et le balayage du cylindre se produisent près de la fin de la course du piston lorsque les orifices d'échappement (F) sont découverts par le piston (C).

    摘要： A valve comprises a hollow valve seat member (4) having a plurality of openings (6) formed therein and a hollow valve member (12) adapted to be moved under an increased water pressure in a pressure chamber (13) to close the openings in the seat member when water reaches its predetermined level. A manually operating valve member (20) is provided to relieve the water pressure in the pressure chamber, thereby allowing movement of the hollow valve member (12) away from the valve seat member (4).

    摘要： The invention is concerned with a method of deriving mechanical work from a combustion gas in an internal combustion engine and reciprocating internal combustion engines for carrying out the method. The method includes the steps of compressing an air charge at least partially in a compressor of the engine, transferring the compressed charge to a power chamber of the engine such that no appreciable drop in charge pressure occurs during transfer and admission to the power chamber, causing a predetermined quantity to produce a combustible mixture, causing the mixture to be ignited at substantially maximum pressure within the power chamber and allowing the combustion gas to expand against a piston operable in the power chamber substantially beyond its initial volume.
