Hydrogen in internal combustion engines has many advantages nov 23 2022

Hydrogen in internal combustion engines has many advantages in terms of combustive properties .  However it needs detailed consideration of engine design to avoid abnormal combustion, which is the major problem in hydrogen engine. This, as a result can improve engine efficiency, power output and reduce NOx emissions.

From the measured parameters, various engine characteristics were calculated, and compared for operation using gasoline and hydrogen as fuels, brake power and torque of the car’s engine when running on hydrogen was generally about 50 –60% of that of gasoline as well as brake specific fuel consumption was in line with expectations from the respective lower calorific values of the two fuels. In addition, thermal efficiency was similar for the two fuels, hydrogen being more efficient at lower power output, and gasoline being more efficient at higher power output.

Besides that, the emission of NOx was significantly lower for hydrogen operation than for gasoline operation and its lowest values were achieved with lambda value around 1.87. Similarly, the emission of carbon dioxide and carbon monoxide and hydrocarbon from the hydrogen engine was extremely low compared the gasoline engine.
