ABSTRACT

The present study investigates the use of hydrogen as a fuel in diesel engines operating under low-load conditions. Due to hydrogen’s higher auto-ignition temperature compared to diesel fuel, it cannot be directly utilized in a diesel engine. As an alternative, hydrogen can be used for enrichment or induction. In this study, a single-cylinder research engine was modified to run on a dual-fuel mixture of diesel and hydrogen to examine the combustion characteristics. Hydrogen was introduced into the intake manifold via a mixer to allow it to enter the combustion chamber. The engine operated continuously at 2000 rpm with a 10 Nm load. Hydrogen was added at flow rates of 21.4, 36.2, and 49.6 L/min. Key parameters such as cylinder pressure, efficiency, and specific energy consumption were analyzed. At this low load, hydrogen enrichment resulted in a reduction in the peak cylinder pressure. The combustion process, including reaction progress and combustion rate, was further explored using OpenModelica modeling.
