Development of a specific electronic control system for an engine dynamometer

With the numerous and complex parameter interactions that take place during the operation of an engine, the optimization of its performance in terms of alternative fuels is difficult, as dynamometers with conventional technology are unable to make significant measurements for alternative fuels. In this study, an electronically controlled dynamometer system capable of measuring a number of specific values was developed. The system allows the optimum values for different fuels to be found for the test engine by monitoring parameters such as injection advance, and at the same time communicating with the electronic control unit via a computer interface. The study presents the algorithm and test results of the system.
