Summary. The article presents the simulation of damage to the engine power (EP) system components and to verify the impact of damage on toxic components emission. The other aim of the article is to simulate the failure of two sensors (the rail pressure sensor and the flow meter), which directly affect the toxicity, and to analyse signal paths during simulated damage. Simulation studies were conducted using the Oliver D60 ophthalmometer following the free acceleration method. Studies included driving a Toyota Avensis powered by 2.2D-4D diesel engine with 2AD-FTV designation and recording of thirty signals in the EP engine control system. The results will allow to correct the exhaust gas composition model.
Key words: exhaust emission, electronic diesel control, OBD system, simulation studies.
