Application of Hydrogen in Internal Combustion Engine and Technical Status and Development

Abstract

Due to future crisis of energy and environmental degradation due to a carbon-containing fuel, hydrogen utilization as a fuel may be better for the near future. Hydrogen’s vitality content per unit volume and larger heating esteem is around 3 times when compared with present fossil fuel [1], and it has a wide range of combustibility limits, and just requires a modest quantity of energy to initiate ignition, also for H2 fuel ignition product is water vapour which doesn’t affect the environment. This paper presents H2 usage as a fuel in IC engines, and it also contains a study on its performance as compared to other fuel and mainly concentrates on various existing methods and various researches of H2 production systems [3] which used to generate H2 and inject it as a replacement for fuel in carburetor air intake. All data of different combustion characteristics was collected from a research paper of various authors [1], [8] given in the reference. The results obtained shows that the greatest estimation of Brake mean effective pressure is acquired at an engine speed of 3000 rpm, this is because of the appropriate burning in engine and increasing H2 content, the CO2 content decreases. It is found that when H2 blends are used as fuel in IC engine, the brake thermal efficiency and most of the emissions were improved.
