a hybrid hydrogen–gasoline engine (HHGE) by adding a hydrogen injection system and a hybrid electronic control unit …. Different from the conventional gasoline and hydrogen–enriched gasoline engines, the HHGE is fueled with the pure hydrogen at … cold start to produce almost zero emissions, with the hydrogen–gasoline blends at idle and part loads to further improve …

performance at low load conditions. This paper experimentally investigated the co-effect of cylinder cutoff and hydrogen addition … engine equipped with an electronically controlled hydrogen injection system and a hybrid electronic control unit. The engine …, respectively. For each cylinder closing strategy, the hydrogen energy fraction in the total fuel (βH2) was increased from 0% to …

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 …

This paper compared the effects of hydrogen and hydrogen–oxygen blends (hydroxygen) additions on the performance of a … engine equipped with a hydrogen and oxygen injection system. A hybrid electronic control unit was applied to adjust the … hydrogen and hydroxygen volume fractions in the intake increasing from 0% to about 3% and keep the hydrogen-to-oxygen mole …

performance of a hydrogen-blended methanol engine at lean and various load conditions. The test was conducted on a four …-cylinder commercial spark-ignition engine equipped with an electronically controlled hydrogen port injection system. The test was … conducted under a typical city driving speed of 1400 rpm and a constant excess air ratio of 1.20. Two hydrogen volume fractions …
