The influence of the hydrogen injection parameters on the performances of the IC engine

Abstract

In order to determine the best injection parameters for hydrogen, an experimental work was performed. The test engine was equipped with the installation for the hydrogen supply, and it was tested how the injection timing and number of injection influence on the performances of the IC engine. As the control parameters were taken the indicating power as well as the indicating work of the engine. It was determined that the injection parameters, significantly influence on the engine working cycle, and by tha6t on indicating power and indicating work of the engine. The adequate injection timing as well as the adequate number of injections, is crucial, for maintaining the stable work oof the IC engine, as well as for obtaining the satisfying engine performances. In order to provide the stable engine work, with the satisfying engine performance parameters, it is necessary provide multiple injections, more accurate two injections, where one serves to provide the adequate amount of fuel for the working cycle, while the second serves to slowdown the combustion process, which is crucial in the case of the hydrogen use.
