Einfluss der Diesel-Piloteinspritzung auf die Verbrennung in Diesel-Gas Dual Fuel Motoren

Abstract

A controversial debate is currently going on in the scientific literature regarding the future importance of diesel-gas dual fuel concepts for large engines. Arguments in their favor are advantages such as the redundancy of the propulsion system when one fuel source fails, the flexibility to adapt the choice of fuel to current prices and also lower emissions in gas operation mode than with a pure diesel engine. Despite gradual advances in dual fuel technology, significant disadvantages in efficiency and combustion stability still exist in comparison to monovalent engines. To increase market acceptance of diesel-gas engines, the focus of development must be to increase efficiency and improve the robustness of combustion concepts.
