This paper illustrates an intelligent testing system, designed in the requirement for the testing of compressed natural gas engine ECU. This system is a virtual environment for ECU’s testing and debugging, it provides all kinds of sensor signals, switch signals and various simulated actuators for ECU. PC can configure the system’s settings and receive testing results through USB. When receiving testing datum, PC judges whether ECU is in normal status according to the datum and saves them in files. Consequently automatic testing is realized.

The use of electronically controlled unit injectors on a high-speed direct injection diesel engine has allowed the development of a new technique for measuring motoring losses. The digital engine controller is programmed to skip successive numbers of injections in a specific circulating sequence, while dynamometer load is adjusted to maintain the desired speed. The linearity between required brake torque and the proportion of disabled to normal injection cycles permits extrapolation of results to find the negative load that would be required to motor the engine at that speed. The method appears to yield more reliable results than traditional approaches, and gives hot motoring values of mean effective torque without the need for external heating or a motoring facility. The equipment and method involved are described, and readings obtained for the whole speed range are presented. These are correlated with losses estimated from pressure measurements, and compared with friction characteristics produced by alternative techniques.
