Abstract—The world is presently confronted with the twin crisis of fossil fuel depletion and environmental degradation. Petroleum crude is expected to remain main source of transport fuels at least for the next 20 to 30 years. The petroleum crude reserves however, are declining and consumption of transport fuels particularly in the developing countries is increasing at high rates. Severe shortage of liquid fuels derived from petroleum may be faced in the second half of this century. Energy security is an important consideration for development of future transport fuels. Recently more and more stringent environmental regulations being enacted in the USA and Europe have led to the research and development activities on clean alternative fuels. Among the gaseous fuels hydrogen is considered to be one of the clean alternative fuel. Hydrogen is expected to be one of the most important fuels in the near future to meet the stringent emission norms. In this experimental investigation, the performance and combustion analysis were carried out on a Direct Injection (DI) diesel engine using hydrogen with diesel following the Time Manifold Injection (TMI) technique at different injection timings of 100, 450 and 800 ATDC using an Electronic Control Unit (ECU) and injection durations were controlled. Further, the tests have been carried out at a constant speed of 1500rpm at different load conditions and it can be observed that brake thermal efficiency increases with increase in load conditions with a maximum gain of 15%at full load conditions during all injection strategies of hydrogen. It was also observed that with the increase in hydrogen energy share BSEC started reducing and it reduced to a maximum of 9% as compared to baseline diesel at 10° ATDC injection during maximum injection proving the exceptional combustion properties of hydrogen.
