Influence of hydrogen injection and ignition parameters on the combustion process in the IC engine

Abstract

Given that the trend of using vehicles has been increasing in recent decades, and as oil reserves are limited and environmental requirements are increasing, there is nothing left but to look for alternative solutions as a replacement for oil derivatives. Alternatives are electric vehicles and hybrid vehicles, but internal combustion engines (IC) should not be written off, alternative fuels such as liquefied petroleum gas (LPG) and compressed natural gas (CNG) are used for spark ignition (SI) engines. There is another alternative fuel for IC engines that is still being tested for use in vehicles, and that is hydrogen (H2). There are still not many published results on hydrogen as a propellant. This paper will present the results of experimental research on the IC engine with hydrogen as a propellant, and the results refer to the parameters of injection and ignition as well as the combustion process, the research was carried out in the Laboratory for IC engines at the Faculty of Engineering, University of Kragujevac.
