摘要： A system for purifying exhaust gas of an internal combustion engine having a NOx reduction catalyst (NOx absorber) installed in the exhaust system of the engine which absorbs NOx in the exhaust gas generated by the engine in a lean environment where a lean fuel mixture is supplied and desorbs to reduce the absorbed NOx in a rich environment where a rich mixture is supplied. In the system, the rich fuel mixture is supplied for a period immediately before cutoff. With the arrangement, the NOx reduction catalyst desorbs the absorbed NOx and is regenerated to absorb NOx sufficiently. At the same time, the NOx reduction catalyst is regenerated from sulfur poisoning, thereby preventing the NOx purification efficiency from being degraded.

摘要： A combustion heater system for use in a moter vehicle has a combustion chamber housing a combustion pad which is heated by a pre-glow plug for vaporizing a fuel that is supplied from a fuel tank through a solenoid-operated valve to the combustion pad. The combustion chamber is supplied with air from a fan, and houses a spark plug for producing sparks in the combustion chamber to ignite a fuel vapor emitted from the combustion pad. The combustion heater system has a control unit which energizes the pre-glow plug to heat the combustion pad, actuates the solenoid-operated valve to supply the fuel to the combustion pad, and actuates the fan to supply air to the combustion chamber. The control unit subsequently energizes the spark plug to produce sparks upon elapse of a preset period of time hereby to ignite the fuel vapor emitted from the combustion pad for producing flames in the combustion chamber. To extinguish the flames, the control unit inactivates the solenoid-operated valve to stop supplying the fuel to the combustion pad and subsequently inactivates the fan to stop supplying air to the combustion chamber.

摘要： An object of the invention is to reliably judge if a NOX absorbent has deteriorated due to sulfur poisoning, or has heat deteriorated. At the time of executing rich spiking, a sulfur poisoning stoichiometric conversion time threshold value tm: LMT-S deterioration, for judging if a NOX absorbent has been sulfur poisoned, and a heat deterioration stoichiometric conversion time threshold value tm: LMT heat deterioration, for judging if the NOX absorbent has heat deteriorated to an extent that the NOX absorption capacity has been lost, are set in relation to the time (stoichiometric conversion time) taken for an output signal from a second O2 sensor to change from lean to rich. When a measurement value of the stoichiometric conversion time is shorter than the heat deterioration stoichiometric conversion time threshold value tm: LMT heat deterioration, it is judged that the NOX absorbent has completely heat deteriorated, and when this is longer than the heat deterioration stoichiometric conversion time threshold value tm: LMT heat deterioration, and shorter than the sulfur poisoning stoichiometric conversion time threshold value tm: LMT-S deterioration, it is judged that there is sulfur poisoning.

摘要： In accordance with an output of an oxygen concentration sensor 16, an air-fuel ratio correction coefficient KO2 is periodically set to values respectively corresponding to a leaner air-fuel ratio and a richer air-fuel ratio with respect to a theoretical air-fuel ratio (steps S22 to S28). Based on an output of an oxygen concentration sensor 16, a NOx amount counter nNOx is counted up, and the amount of NOx absorbed by a NOx absorbent catalyst is estimated. When the value of the NOx amount counter nNOx reaches a preset value NSAT, an air-fuel ratio of an air-fuel mixture is set to be further richer than the richer air-fuel ratio.

摘要： A torque shock alleviating device in a hybrid vehicle utilizing both an engine and an electric motor as drive sources, whereby a torque shock is not generated when the rich-spiking of the air-fuel mixture is carried out in order to restore the adsorbing ability of an NOx adsorbing device in the hybrid vehicle. When an engine is operated in a lean burn manner, NOx in an exhaust gas is adsorbed to an NOx adsorbing device provided in an exhaust passage. When the adsorbing ability of the NOx adsorbing device reaches a saturated level, a rich-spiking for temporarily enrichening the air-fuel mixture of the engine is carried out to restore the adsorbing ability of the NOx adsorbing device. When the output torque from the engine is increased by the rich-spiking, a regenerative braking force is generated in a motor, thereby moderating the increase in output torque from the engine by such regenerative braking force to alleviate the torque shock. An electric power generated by the regenerative braking is supplied for the charging of a battery.
