A Review of Hydrogen as a Fuel in Internal Combustion Engines

Blog Article

The demand for fossil fuels is increasing because of globalization and rising energy demands.As a result, many cashel tail bag nations are exploring alternative energy sources, and hydrogen is an efficient and practical alternative fuel.In the transportation industry, the development of hydrogen-powered cars aims to maximize fuel efficiency and significantly reduce exhaust gas emission and concentration.The impact of using hydrogen as a supplementary fuel for spark ignition (SI) and compression ignition (CI) engines on engine performance and gas emissions was investigated in this study.By adding hydrogen as a fuel in internal combustion engines, the torque, power, and brake thermal efficiency of the engines decrease, while their brake-specific fuel consumption increase.

This study suggests that using hydrogen will reduce the emissions of CO, UHC, CO2, and soot; however, NOx emission is expected to increase.Due to the reduction of environmental pollutants for most engines and the related 2nd recon battalion patch environmental benefits, hydrogen fuel is a clean and sustainable energy source, and its use should be expanded.
