| 摘 要： | IntroductionEngine performance and exhaustemissions arecontrolled by a great number of control parameters( constants,curves and maps) in the ECU relatedto injection system,combustion chamber geome-try,boost pressure and EGR percentage. As iswell known,all these parameters are required tobe changed and calibrated again and again,so thecalibration workload is very big.And many itemsof exhaust emissions,such as good NOX and sootengine- out level predictions,are strictly linked notonly to the …

| Abstract: | Based on CAN calibration protocol, a new calibration and monitoring system was developed for the GD-1 high pressure common rail diesel engine. CAN driver block, monitoring program and calibration program for this system were designed respectively. The inquiry mode was used in the monitoring program and the interrupt mode was used in calibration program. The calibration program was designed in structural programming model. This system provides a reliable, accurate and quick CAN bus between ECU and PC, with baud rate up to 500Kbit/s. The implementation of the compatible and universal CAN calibration protocol makes it easy to displace the system and its function modules. It also provides friendly, compatible and flexible calibration interface, and the functions of online calibration and real-time monitoring. This system was successfully used in a GD-1 high pressure common rail diesel engine and the engine performance and exhaust emissions were significantly improved. |
