Hardware-in-the-Loop Testing of Electronically-Controlled Common-Rail Systems for Marine Diesel Engine

Tougher legislation on exhaust emissions reduction, more power and mobility and less fuel consumption, has led to stronger call for the electronic engine control units for marine diesel engines. Electronically-controlled common-rail systems for marine diesel engine is introduced in the paper. Testing method based on Hardware-in-the-loop(HIL) simulation is depicted in details. The specified HIL platform is founded upon the NI products, while the mean value engine model(MVEM) of marine diesel engine and its accessorial parts are constructed in MATLAB/Simulink environment. Software of LabVIEW and Simulink are combined together with the Simulation Interface Toolkit. Implementation results show the feasibility of the unconventional solution, which will certainly play more important role in future marine engine controller development.
