This paper describes the development of a computer program using the programing software LabViewTM. This computer program is capable of performing real-time electronic management of a Common Rail Diesel cycle engine. This management is done openly, ie can be varied in real time execution input parameters and thus experience the engine response depending on the variation of these parameters. The computer program is focused on a real-time controller NI CRIO9004 model available from National Instruments Co, which conditions and processes the input signals from several engine sensors and generates output signals to control the various engine actuators. The management of many engine concepts in close loop is performed with the aim of obtaining very precise control of these elements and adaptability to rapid transients.
