Comprehensive Review of Efficiency Enhancement Techniques for Dual-Fuel Compression Ignition Engines with and without Nano-Additives

Abstract

Currently, hydrogen gas is being used in several applications and its impact during combustion, using with & without additives and hydrogen blends modified dual fuel engine, especially for combustion and energy generation purposes due to its chemical features. Furthermore, the flame speed and calorific value render hydrogen highly suitable for diesel engines. The trends in vehicle engine design and development have shifted toward the replacement of advanced and efficient fuels. The existing patterns of injections, the innovations in diesel engines, and the prospects of using them for increasing engine effectiveness are all analyzed. The incorporation of H2 as a secondary fuel in DE is under scrutiny. This is done by varying the speed of the engine along with controlling the amount of hydrogen burnt for heat and power. This paper aims to establish appropriate conditions for the application of hydrogen as an additional fuel without neglecting the environmental impacts or the efficiency of the engine. These studies can potentially lead to the development of advanced means of transportation that are both efficient and environmentally friendly. To understand the more holistic environmental impacts, this research will also analyze emissions produced by hydrogen when used as an auxiliary fuel in a diesel engine. This work aims to minimize dependence on fossil fuels by transforming vehicles and powering them, and also identifies that the nano additive in dual fuel (hydrogen-Disel fuel) enhances the maximum efficiency and reduces harmful emissions. These studies can lead to the development of transportation means that are both sustainable and effective. In order to lessen the effects on the atmosphere, the research will also analyze the emissions when hydrogen is applied as an auxiliary fuel. It is expected that the results of this study will help transform vehicle power systems while greatly decreasing the use of traditional fossil fuels.
