In this paper, an expert system for deciding running condition and diagnosing faults of medium and large-sized diesel engines are presented. The system consists of three parts. First is the transient data acquiring part by which the necessary parameters of the engine can be acquired through the A/D transforming circuits, Second is the simulative calculation part by which we can able to calculate subsequent spatial and temporal history of most of the parameters, such as burning rate, local temperature, NO emission and soot etc, and according to this information, the best running condition for marine diesel engines can be decided. By com-paring the experimental with calculated values for the engines, it is revealed that the model predicts with good accuracy engine performance and with reasonable accuracy nitric oxide emissions. Third is the expert diagnostic part, which is still not completed because of lacking of the data.
