摘要： A method is described of operating an internal combustion engine burning a fuel containing carbon and hydrogen, to provide a flame in the exhaust system to heat a catalytic converter or burn off the soot in a particulate filter trap. The method involves reducing the intake throttle opening during deceleration mode below the throttle opening for the steady speed idle position to create a proportion of combustible gases in the exhaust gas stream. By ensuring at the same time the presence in the exhaust gas stream of additional air, an ignitable mixture is produced which is ignited to burn as a flame in an afterburner chamber of the exhaust system. By selecting deceleration periods to enrich the mixture excessively in this manner, adverse effects on drivability go unnoticed.

摘要： A lean burn internal combustion engine is described having at least one cylinder. An intake port (24) supplies an intake charge to the combustion chamber (10) of the cylinder and the exhaust gases are discharged through an exhaust port (26). Fuel is supplied by a fuel injector (28) for dispersion within the air drawn into the combustion chamber (10) by way of the intake port (24), and exhaust gases from the exhaust port (26) are recirculated to the intake port (24) without passing through the combustion chamber (10) by way of an external EGR pipe (30). To promote lean burn and auto-ignition at low engine load, an additional fuel supply (40) is provided in the EGR pipe (30) for introducing fuel to be partially oxidised within the hot EGR gases before they enter the intake port (24).

摘要： An internal combustion engine (12) is disclosed having a catalytic converter (10b) and an exhaust gas ignition (EGI) system for assisting in reducing the light-off time of the catalytic converter (10b). The EGI system comprises means (21) for enriching the mixture in the engine combustible charge during cold starts in order to produce exhaust gases containing sufficient hydrogen and carbon monoxide to be ignitable when cold upon the addition of air to the exhaust gas mixture, and means (18) for igniting the mixture upstream of the catalytic converter (10b) to generate a flame for heating the catalytic converter. To increase the hydrogen content in the exhaust gases for any given mixture strength supplied to the engine combustion chambers, the invention teaches advancing the spark timing of the engine, or retarding the opening of the engine exhaust valves, during operation of the EGI system to achieve a lower burnt gas temperature prior to the opening of the exhaust valves.

摘要： A stratified charge internal combustion engine comprises at least one cylinder having at least one intake valve (14) per cylinder, and two manifolds (24, 34) having branches (22, 32) supplying first and second gas streams to at least one intake valve of each cylinder. The two streams enter the cylinder separately through different regions of the valve (14) so as to produce a stratified charge within the engine cylinder. The first manifold (24) supplies a stream comprising air within which fuel to be burnt is dispersed and the second manifold (34) supplies a stream comprising dilution gases. Each of the two manifolds (24, 34) has a plenum chamber and the plenum chambers of the two manifolds are connected to a common air supply throttle (50). The plenum chamber (34) of the second manifold is additionally connected to an exhaust gases recirculation (EGR) pipe (84) from the exhaust system of the engine through an EGR throttle (54) of similar design to and mechanically ganged with the air supply throttle (50). The EGR pipe (84) supplies exhaust gases directly into the second stream to form part of the gases in the second stream. The relative quantity of air in the first stream supplied by the first manifold (24) as a fraction of the total quantity of air supplied to the two manifolds (24, 34) is variable and determined by the setting of the relative quantity of EGR flow as a fraction of the total air flow.
