The faults considered were air-mass ow sensor fault, intake-manifold pressure sensor fault, air-leakage, and the EGR-valve stuck in closed position. A non-linear engine model, with four states, is constructed. The diagnosis system is then constructed in the framework of structured hypothesis tests, andby using adaptive observers. The diagnosis system is successfully evaluated in a real car driving on the road.Inga fysiska exemplar för denna post
A model based diagnosis system for the air-path of a turbo-charged diesel engine with EGR is constructed.
