The design and implementation of the hardware in-the-loop simulation comprehensive test bench of high pressure common rail electronic control system for large low-speed marine diesel engine
This paper presents the design and implementation of the hardware in-the-loop (HIL) simulation test bench of high pressure common rail (HPCR) electronic control system for large low-speed marine diesel engines. As a first step , the vital components of HPCR system in the bench are the same as that of the RT-Flex marine diesel engine, such as the W(a)rtsil(a) Electronic Control System (WECS), the fuel high pressure common rail, the servo oil common rail, the fuel injection control unit and the exhaust valves control unit, etc. And some auxiliary parts are simplified and modified, including the crank angle signal unit, the exhaust valve actuator, the fuel and servo oil supply unit, etc. Secondly, a real-time simulation model of the marine diesel engine is described and implemented based on the principles of Mean Value Engine Model, which provides the essential boundary conditions for WECS. The electrical emulation of the model mainly consists of the crank angle, the exhaust valve stroke, and the scavenging pressure thanks to the NI environment. Additionally, an experiment management system for the test bench is developed with the functionalities of signal acquisition, parameters monitoring, data extraction and alarming, etc. Finally, a closed-loop control system composed of the real-time simulation model, WECS and the mechanism of HPCR system, is achieved. And the testing results of the HIL simulation platform, calibrated with experimental data on steady operating conditions, indicate that the test bench performs the characteristics and functions of the HPCR electronic control system. The bench provides the experimental environment for researching on HPCR electronic control system for large low-speed marine diesel engines.
