The power of a hydrogen-fueled engine higher than gasoline had been disturbed by backfire. Therefore, in order to get the power of higher than gasoline engine level in a hydrogen-fueled SI engine, the change in the valve timing and the effect of the lean boosting are analyzed.
As the results, the exhaust valve closing timing is not worked on backfire control, but the intake valve opening timing is worked. In addition, it is confirmed that the power of higher than gasoline engine level and NOx-free are achieved by lean boosting. This value are obtained under 2.1bar and Φ=0.3.
