| Abstract: | Diesel engine exhaust gas aftertreatment was realized by fixing the oxidation catalytic converter only.The inlet condition of DPF initiative regeneration under given conditions was determined through the experiment.The engine operating point of DPF initiative regeneration was found by measuring the exhaust temperature.Meanwhile,the injection pulse width of liquefied petroleum gas(LPG) in the exhaust pipe was acquired.In the experiment,the HC conversion efficiency was higher than 90%,which satisfied the requ... |
