The influence of the hydrogen injection parameters on the combustion process of IC engine

Abstract

In order to determine the best injection parameters of 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 combustion process. As the control parameters were taken the engine working stability, as well as the indicating efficiency. It was determined that the injection parameters, significantly influence on the engine working cycle, as well as on the combustion process. 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 indicating efficiency. In order to provide the stable engine work, with the satisfying indicating efficiency, 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.
