| Abstract:Diesel engines feature complicated combustion process, numerous influencing factors and great difficulty in fault isolation. A high-power diesel engine simulation model was built based on AVL BOOST to simulate its typical faults and explore the variation rule of combustion parameters under different fault modes. The correlation between fault modes and combustion parameters were studied based on simulation results, and the correlation matrixes between different typical faults and combustion parameters were obtained and verified by test, which can be used as the basis of fault isolation. |
