| Abstract: | The factors affecting the back pressure of diesel particulate filter(DPF) are studied on exhaust duct tester built and real vehicle test system.In addition,the time histories of flow rate,back pressure and temperature in some working conditions of engine are quantified.These provide powerful data support for judging the appropriate regeneration time of DPF. |
