文摘
- •
Hydrogen addition improved the burning rate of mixture and flame velocity.
- •
Hydrogen acts as a flame kernel while setting fire on mixture.
- •
Lean-burn performance gets improved due to extended flammability after hydrogen added.
- •
Carbonic emission reduced with additional of hydrogen.
- •
Direct injection combined with tumble flow enhanced the effect of hydrogen addition.
