摘要： An electronically controlled exhaust gas purifying system for use with an internal combustion engine of a motor vehicle including not only a catalytic converter but also an auxiliary thermal reactor which is located upstream of the catalytic converter and by which exhaust gases emitted from the engine is re-combusted to the extent that the catalytic converter is not destroyed or damaged by the residual unconsumed compounds in exhaust gases discharged from the thermal reactor. The system is provided with an electronic control means for shutting off the flow of secondary air to be mixed with the exhaust gases emitted from the engine both when at least one of the temperatures of the catalytic converter and the thermal reactor rises above a critical value at which they would be destroyed or damaged, and when the engine is under cranking operation. The electronic control means retards the spark in order to heat the exhaust gases when the temperature of the reactor falls to its reaction commencement temperature. In the event that the rate of temperature rise of the thermal reactor exceeds a threshold value, the electronic control means does not retard the spark even if the temperature of the thermal reactor falls to the reaction commencement temperature, but then retards the spark when the temperature of the thermal reactor falls below a predetermined value which is set lower than that of the reaction commencement temperature.

摘要： An exhaust gas purifying system (1) having a continuous regeneration DPF (3) installed in the exhaust passage (2) of a diesel engine (E) provided with a glow plug and a regeneration control means for regenerating the continuous regeneration DPF (3), is constituted so that the regeneration control means performs retarded injection or post-injection in the control of fuel injection into a cylinder (13) and heating the inside of the cylinder (13) by the glow plug (16) for regenerating the continuous regeneration DPF (3). Thereby, when raising the temperature of exhaust gas in the regeneration of the continuous regeneration DPF (3), it is possible to prevent the generation of white fumes and misfire and to raise the exhaust gas temperature efficiently and substantially. Therefore, it is possible to prevent the temperature of a catalyst and a DPF from being abnormal high and to prevent the deterioration and the melt down of the catalyst.
