Abstract
A diesel particulate filter (DPF) model that can be incorporated with whole vehicle model to simulate a transient driving condition was developed using OpenModelica software. A particle oxidation process in the model is expressed as a simplified single step reaction, and occur even in the situation that a regeneration is not appeared. Regeneration properties observed with a DPF diesel passenger car was reproduced with the model. According to the results with the passenger car model, an appropriate regeneration control, which terminates the regeneration at the point where soot remains to some extent, will improve the fuel economy.
