Development of Regeneration System by Fuel Injection for Diesel Particulate Filter

The particulate matter of diesel exhaust is emissions which have a harmful to human health.Diesel particulate filter be considered as an effectively technology for diesel exhaust after treatment.Aiming at solving the problem that the regeneration system of diesel particulate filter is too complicated or unreliable,a new catalytic regeneration scheme based on diesel oxidation catalyst,diesel particulate filter,fuel additive is presented.The circuit of control unit and the concrete control method are analyzed in detail.The test in bench and on road shows that the regeneration system can reduce more than ninety four percent the pollutants of diesel.
