Co-Combustion of Hydrogen with Diesel and Biodiesel (RME) in a Dual-Fuel Compression-Ignition Engine

The utilization of hydrogen for reciprocating internal combustion engines remains a subject that necessitates thorough research and careful analysis. This paper presents study on the co-combustion with diesel fuel biodiesel (RME) in compression-ignition piston engine operating at maximum load, content up to 34%. employed indication exhaust emissions measurement assess engine’s performance. Engine allowed determination key stages, including ignition delay, time, angle 50% heat release. Furthermore, important operational parameters such as indicated pressure, thermal efficiency, specific energy consumption were determined. evaluation dual-fuel stability was conducted by analyzing variations coefficient variation mean effective pressure. increase proportion co-combusted had negligible impact delay led reduction time. effect more pronounced when using (RME). In terms 12% resulted highest efficiency engine. However, greater gains observed powered RME. It should be noted hydrogen-powered RME exhibited slightly less stable operation, measured COVIMEP value. Regarding emissions, compression demonstrated favorable outcomes CO, CO2, soot while NO HC increased.
