| Abstract:The layout of sensors and cables of 20RK270 diesel engine could not meet the latest demands for automation and intelligence. To deal with this problem, the layout of sensors and cables are optimized to a new design according to the structural and application characteristics of 20RK270. The main design ideas are:complete isolation of speed signals, eliminating the errors of temperature sensors, integration of nearby sensors or sensors with similar functions, integration of sensor cables with similar transmission signals. The application results showed that the assembly procedure was simplified, errors during assembly were decreased and production efficiency was increased. Meanwhile, the operation stability of the diesel engine was improved. |
