本文介绍在水力测功器的基础上,采用Z80单板机构成的柴油机性能测试微机控制系统。该系统能按工艺要求对柴油机在特定工况下的性能指标(转速、功率、油耗、调速率、排气温度等)进行全面的自动测试和连续显示;并能对柴油机的转速及负荷进行闭环控制,测试结束,自动将测试结果制表打印。 This article describes the hydraulic dynamometer based on the use of Z80 single-board machine into a diesel engine performance test microcomputer control system. The system can fully automatic test and continuous display of the performance indicators (speed, power, fuel consumption, speed regulation, exhaust temperature, etc.) of diesel engine under certain operating conditions according to the technical requirements. The system can also measure the speed and load of diesel engine Closed-loop control, the test is over, the test results automatically tab print.
