Abstract

The invention discloses a burner DPF regeneration control system based on the parking warm-up idling condition. The input signal of the system comprises an ignition key switching signal, a manual force starting regenerative switching signal, a manual force closing regenerative switching signal, a vortex rear exhaust gas temperature sensor signal, a DPF front temperature sensor signal, a DPF rear temperature sensor signal, a DPF differential pressure sensor signal and an air flow sensor signal; an electric control unit controls a fuel electromagnetic pump, an air pump and an ignition preheatingplug; and the vortex rear exhaust gas temperature sensor signal, the DPF front temperature sensor signal, the DPF rear temperature sensor signal and the DPF differential pressure sensor signal are inputted in the electric control unit to provide a regeneration timing triggering condition and a temperature protection mechanism judgment condition. The burner DPF regeneration control system realizesparking active regeneration under the steady-state idling condition, so that the fuel consumption is prevented from being excessive, the regeneration temperature is controllable and safe, and the uncontrollable regeneration condition can be avoided.

Description

technical field [0001] The invention relates to the field of post-treatment manufacturing of diesel engines, in particular to a burner DPF regeneration control system based on parking warm-up and idling working conditions. Background technique [0002] At present, the rapid development of motor vehicles is accompanied by serious air pollution, showing the characteristics of regional complex. The air pollution in many big cities has changed from soot-type pollution to combined soot and motor vehicle pollution, and a few megacities have clearly shown photochemical smog-type (ie, motor vehicle exhaust) air pollution. Therefore, the research on diesel vehicle exhaust emission pollution control technology is extremely important and urgent. Particulate matter is a major pollutant in the exhaust emission of diesel vehicles, and the particulate matter treatment technology mainly reduces the particulate matter in the exhaust by means of capture. In terms of reducing particulate mat...
