Globalization and the rising demand for energy have certainly led to ever greater needs in fossil fuel. Certainly several nations are researching new sources of energy, and hydrogen is a fuel that burns cleanly. Meanwhile in the transportation industry, hydrogen-powered cars being developed aim at once for maximum fuel efficiency and for significantly less poisonous vapors in the air for people to breathe but also caused by their partial exhausts--because these are now eliminated entirely thanks to complete conversion of hydrocarbons into water vapor plus some extra CO2.Using this review, the author wants to do a summary of how hydrogen is a internal combustion engine fuel, covering both spark-ignition (SI) and compression-ignition (CI) motors.Using hydrogen as a fuel for internal combustion engines lowers the torque, output, and brake thermal efficiency of them while their brake-specific fuel consumption changes little. There is data that indicates that by using hydrogen, emission of CO, UHC, CO2 and soot from an engine can be reduced. On the other hand, NOx is expected to increase because more air enters into the combustion chamber to pick up a large amount of water vapor in addition.Hydrogen fuel, as an energy source, is clean and renewable which can promote sustained development of the environment for everyone to enjoy.
Highlights:
- Hydrogen reduces major emissions such as CO, UHC, CO₂, and soot in IC engines.
- Engine performance decreases slightly, with lower torque and brake thermal efficiency.
- NOx tends to increase due to higher combustion temperatures and excess air.
Keywords: hydrogen fuel ; Hydrogen ICE; renewable energy; efficiency; emissions
