The application of electronic control devices for electronic control devices is critical for the precise control of diesel engine performance and for diesel vehicles to meet extremely low emission requirements. A typical ECM (Electronic Control Module) can handle thousands of input information, output commands or fault information, and can continuously organize and determine these information parameters. In addition, today's electronic control systems should be adapted to operators, vehicles, and maintenance personnel to optimize the entire operation process. For example, the system can provide users with trip information including kilometers, fuel, and lube conditions to better use the vehicle or evaluate the performance of the vehicle; through the electronic diagnostic tool, the factory can easily obtain the full information of the engine and take Effective measures to improve the condition of the vehicle. The electronic control system can better manage the lubricant used. The Cummin.sCentinel system does not need to be replaced by the continuous consumption of engine oil by the fuel system. The system processing program is controlled by the ECM, determines the diesel injection rate, and can warn the operator when the engine is not normally starting or operating. In the near future, lubricant level sensors will be used to warn of lubricant level deficiency and change the operator's traditional way of refueling; when using different fuels, fuel viscosity and density sensors will automatically correct the fuel injection rate; The vehicle lubricant change indicator will provide information on the critical condition of the oil change intervals.
