Engine control by electronic central unit (ECU) can be quickly described by information coming from sensors sent to the ECU, and by calculated and setting values sent to actuators by the ECU [1]. This paper describes idle regulation observations on an engine simulator, allowing an existing ECU, coming from an existing vehicle, to be emulated. Various submodels, such as starting models or road simulation models, allow idle pintle motion patterns to be generated. The paper shows what kind of idling strategies an engine control system has to take into consideration.
