Review on utilization of waste heat & renewable fuels in Internal Combustion engine

In this article, review on hydrogen internal combustion engines is discussed. The objective of this paper is to provide a means of waste heat and renewable hydrogen based fuel utilization. Energy, once used, is not regenerative. This means that, during any energy activation, we are filling up the space and Planet with parasite in the forms of energy (Anergy) or Global warming. The development of a high efficiency, low emissions electrical generator will lead to establishing a path for renewable hydrogen based fuel utilization. The increasingly worldwide problem regarding rapid economy development and a relative shortage of energy, the internal combustion engine exhaust waste heat and environmental pollution has been more emphasized heavily recently. Out of the total heat supplied to the engine in the form of fuel, approximately, 30 to 40% is converted into useful mechanical work; the remaining heat is expelled to the environment through exhaust gases and engine cooling systems, resulting in to entropy rise and serious environmental pollution, so it is required to utilized waste heat into useful work. The recovery and utilization of waste heat not only conserves fuel (fossil fuel) but also reduces the amount of waste heat and greenhouse gases damped to environment. This paper deals with the availability and possibility of waste heat from internal combustion engine, also describe loss of exhaust gas energy of an internal combustion engine.
