Abstract

This study aimed to identify experimentaly the optimal operating strategy for a single-cylinder hydrogen compression ignition engine by analyzing the effects of hydrogen addition on energie efficiency, combustion characteristics and polluants emissions, in a single-cylinder CIE. Experiments were conducted at 1500 rpm with various engine loads, using different modes: conventional diesel, hydrogen diesel (

H_{2}

-D) like dual fuel, natural gas-diesel conventional dual fuel and hydrogen enriched natural gas- diesel dual fuel. As results, the

H_{2}

-D like dual fuel mode delivered optimal performance and low emissions at low to moderate loads (20 % to 60 % of full capacity). At high engine load (80 % of full capacity), with high hydrogen substitution rates (20 %), natural gas-hydrogen/diesel dual fuel mode outperformed conventional diesel engines in C

O_{2}

and PM emissions reduction as well as diesel fuel utilization. Despite an increase in NOx and THC at full load, natural gas dual fuel mode delivered better energy efficiency and environmental outcomes compared to other modes.
