Design and experimental study on an equipment for heating exhaust from turbocharged diesel engine

An pyrogenation equipment which comprises burner, air-taken,and fuel- supplied system is designed to heat the exhaust gas from diesel engine and regenerate the diesel particulate filter. The innovation point lies in using the compressed air from turbocharger to combust with fuel. The equipment is installed between BJ493ZQ3 engine vent-pipe and DPF, the feasibility is testified and the experimental study is carried out. The study showed that the exhaust gases can be heated up to 500□ over a wide operating range within 3 minutes, meanwhile, the energy consumption is little and the cost is low, the regeneration efficiency is high and operation is simple. The set is easy to equip with auto, the regeneration reliability is ensured as well as the traditional question from heat regeneration way is solved.
