Computer Aided Engineering of Diesel Filter Systems

Increasingly stringent international diesel particulate emissions standards have re-established interest in Diesel filters. Modern Diesel engine technology, with computerized engine management systems and advanced, common rail injection systems, needs to be fully exploited in order to allow the application of efficient and durable Diesel filter systems, usually supported by catalytic aids, as standard equipment in passenger cars. Significant manpower, computational and testing resources are invested in this effort and mathematical models are indispensable in components’, control and overall system optimization. In this paper, a model of Diesel filter operation adapted to work in Simulink environment is applied to regeneration control system optimization.
