Abstract
The regeneration was the main barrier restricting the development of diesel particulate filter (DPF), and the exhaust thermal management control strategy are the premise of efficient DPF active regeneration. This paper took a light vehicle equipped with high-pressure common rail diesel engine as the object, studied the influences of exhaust thermal management including intake throttling, fuel injection strategies and late post injection (LPI) coupling diesel oxidation catalyst (DOC) on exhaust temperature by experiment. The results indicated that the reduction of intake throttle valve opening at low speed and light load working conditions, where the exhaust temperatures were low, could dramatically increase the exhaust temperature. With a reasonable match of fuel injection parameters, the exhaust temperature could be increased. LPI coupling DOC could have a further increment on exhaust temperature, but it would have obvious negative effects on fuel economy and hydrocarbon emissions at the same time. In this paper, a comprehensive exhaust thermal management control strategy was proposed. The test bench indicated clearly that the demand of DPF regeneration temperature can be met in most working conditions through the reasonable integrated control strategies of exhaust thermal management.
