The experiment was conducted on a modified four-cylinder SI … engine equipped with an electronically controlled hydrogen injection system and a hybrid electronic control unit. The engine …

The performance of a hydrogen-blended gasoline engine at lean and the wide open throttle conditions was investigated. A … hydrogen port-injection system was adopted to introduce the hydrogen into each cylinder. The engine was operated at 1400rpm and … two hydrogen blending levels of 0% and 3%. The excess air ratio was raised from 1.00 to about 1.45 for a given hydrogen …
