Abstract

The invention discloses a marine medium speed diesel engine high pressure common rail system hardware-in-loop simulation test platform and a test method. The test platform comprises a common rail system auxiliary unit, a common rail execution mechanism, a virtual marine medium speed diesel engine, an electric control unit, a test platform monitoring system and a local control system. The complete high pressure common rail execution mechanism and the electric control unit are integrated; the virtual diesel engine is used for providing an actual working condition for the electric control unit and the local control system, and the test platform is highly integrated and comprehensive, and research and test on features of the high pressure common rail system, control strategies and performance of the execution mechanism can be carried out. The complete common rail system is kept, fuel pump operation, fuel injection and diesel engine operation state parameters which are the same as those of a real diesel engine can be realized in a lab, working condition changes of the virtual diesel engine can be realized through steering a telegraph lever, and the test platform of the invention can serve as research and teaching equipment for the marine diesel engine high pressure common rail system and has promotion and use values.

Description

technical field [0001] The invention relates to the technical field of internal combustion engine engineering, in particular to a hardware-in-the-loop simulation test platform and a test method for a high-pressure common rail system of a marine medium-speed diesel engine. Background technique [0002] Marine diesel engines are the most important supporting equipment for ships, and diesel engines are still the most important power source for commercial ships at present and in the future. Fuel costs are an important part of ship operating costs. At the same time, as the International Maritime Organization has become more stringent on marine diesel engine emissions, improving the economy of marine diesel engines and reducing emissions has become a research focus. High-pressure common rail technology is one of the core key technologies for performance optimization of marine diesel engines such as reducing fuel consumption and controlling emissions. It can flexibly control the fu...
