Abstract

It is important to reduce emissions from diesel engines, which are used in the cogeneration systems. The mass transfer to the fuel spray plays various roles in fuel consumption rate and in trace species emission. High injection pressure and a re-entrant combustion chamber were used to make the mass transfer larger. The need for high injection pressure and controlled injection timing for NOx led the authors to use the new Komatsu fuel injection pump. This pump, which has a re-entrant combustion chamber, resulted in clean engine emissions and confirmed the importance of air entrainment to the spray.
