European regulations regarding exhaust gas emissions have constantly become more restricted in the last decades. Components of the exhaust gas after-treatment system and ECU strategies have become correspondingly more complicated in order to fulfil the prescribed limits. This paper describes how a real time HIL engine simulator can be used to test EOBD ECU strategies, in order to reduce the amount of costly experimental tests. Strategies for the exhaust gas after-treatment system have been tested on HIL. The results of the tests show the feasibility of HIL testing of EOBD strategies.
