The rapid depletion of fossil fuel and growing demand necessitatesresearchers to find alternative fuels which are clean and sustainable.The need for finding renewable, low cost and environmentally friendlyfuel resources can never be understated. An efficient method of generationand storage of hydrogen will enable automotive manufacturers to introducehydrogen fuelled engine in the market. In this paper, a conventionalDI diesel engine was modified to operate as gas engine. The intakemanifold of the engine was supplied with hydrogen along with recirculatedexhaust gas and air. The injection rates of hydrogen were maintainedat three levels with 2 L/min, 4 L/min, 6 L/min and 8 L/min and 10L/min with an injection pressure of 2 bar. Many of the combustionparameters like heat release rate (HRR), ignition delay, combustionduration, rate of pressure rise (ROPR), cumulative heat release rate(CHR), and cyclic pressure fluctuations were measured. The HRR peakpressure decreased with the increase in EGR rate, while combustionduration increased with the EGR rate. The cyclic pressure variationalso increased with the increase in EGR rate.
