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.

Abstract: A multi-cylinder spark ignition internal combustion engine is described having two groups of cylinders (10a, 10b). One group of cylinders may be selectively disabled by cutting off its fuel supply while continuing to receive air. The exhaust system includes an NOx trap (20) to store NOx gases while the exhaust gases contain excess air. During part load operation, the engine is run with one group of cylinders disabled most of the time during which NOx gases are stored in the NOx trap (20). In order to permit the trap (20) to be regenerated or purged periodically, both group are fired at the same time for short intervals to supply a stoichiometric or reducing mixture to the exhaust system.

Abstract: 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.

Abstract: A method is described for reducing the total emissions during cold starts from an engine burning a hydrocarbon fuel and having an afterburner arranged upstream of a catalytic converter. The method comprises the steps of: (i) adding an excess of fuel to the engine combustible charge and adding air to the engine exhaust gases immediately after the engine has first fired to assure the presence in the exhaust/air mixture of sufficient concentrations of hydrogen and oxygen to permit the resulting exhaust/air mixture to be ignitiable and to burn with a steady flame in the afterburner while the latter is at a temperature close to the ambient temperature, and (ii) igniting the exhaust/air mixture in the afterburner immediately after the engine has first fired. In the preferred embodiment of the invention, the excess fuel and/or the additional air are regulated after ignition has occurred in the afterburner to maintain a steady flame in the afterburner until at least part of the matrix of the catalytic converter has reached its light off temperature.
