Special aspects of the test of ATV equipped with the electronic engine management system Continental M3C on a dynamometer test bench

In this article the problems of taking characteristics of the power plant of BRP Can-Am Outlander max 570 at its loading on a dynamometer test bench DynaPack are considered. The possibilities of using input and output electrical signals of sensors and actuators of the electronic engine management system Continental M3C, including the use of third-party electronic engine management unit M74CAN cars VAZ. The schematic solutions for obtaining the value of the engine crankshaft speed of the ATV by the standard software of the DynaPack dynamometric stand are proposed. Based on the analysis of the developed circuit solutions, as well as the features of loading, power plant in general, and the engine in particular, on the dynamometer test bench DynaPack decided to use the fuel injector control signals to determine the speed of the crankshaft engine. To increase the stability of the results of the series of experiments, a method of monitoring the position of the engine throttle valve was proposed. In conclusion, the speed characteristics of the BRP Can-Am Outlander max 570 quad bike power plant at various levels of opening the throttle valve are shown.
