Abstract (en)
[origin: WO2012015505A1] A system and method for efficient regeneration of a diesel particulate filter used in the exhaust system of a diesel engine, is disclosed. In various systems, a burner is incorporated into the exhaust stream, and prior to the diesel particulate filter. Because the burner requires precise amounts of fuel and air to operate properly, an air flow delivery device, such as a positive displacement pump or blower is incorporated into the system to channel boost air to the burner. Alternatively, a bypass line may be used in conjunction with a pressure regulator, wherein the bypass line diverts the boost air from the pump or blower, while the pressure regulator controls the final pressure to the burner.
