| Abstract(E) | To improve thermal efficiency while keeping extremely low NOx emissions of spark ignition engines, a new combustion technique which combined pre-chamber combustion with fuel reforming has been proposed and experimentally demonstrated. In this report, for the purposes of investigating for the effects of pre-chamber specifications on combustion in pre-chamber and main chamber, specifications of pre-chamber nozzles were varied and the engine performance was evaluated on a single cylinder pre-chamber gasoline engine. As results, effects of pre-chamber specifications were clarified, combustion characteristics in pre-chamber and main chamber were improved, and stable operable regions was extended up to lambda 3.0. |
