New high quality diesel engine Yangchai 2.3
Description
- The diesel engine electronic control system takes the diesel engine speed and load as the basic signals reflecting the actual working conditions of the diesel engine, and determines the basic fuel injection quantity and fuel injection timing MAP with reference to the fuel injection quantity and fuel injection timing MAP corresponding to each working condition of the diesel engine obtained from the test. Timing, and then various compensations are made according to various factors (such as water temperature, oil temperature, atmospheric pressure, etc.), so as to obtain the best fuel injection quantity and fuel injection timing, and then control output through the actuator. difficulty a. High requirements for system actuators b. Control strategies need careful study advantage a control function c. high control precision, fast dynamic response b. Provide greater freedom of control The electronically controlled fuel injection system can perform optimal comprehensive control on fuel injection parameters (such as fuel injection volume, fuel injection timing, fuel injection pressure, fuel injection rate, etc.) according to different operating conditions. The influence of various factors on the performance of the diesel engine can also be considered. c. System optimization and calibration work is difficult and heavy workload d. Provide fault diagnosis function to improve reliability e. It can improve engine power, economy and emission performance
