Bioethanol and gasoline premixing effect on combustion and emission characteristics in biodiesel dual-fuel combustion engine

The purpose of this study is to examine the effects of bioethanol and gasoline as a premixed injection source on the combustion performance and exhaust emissions characteristics of a dual-fuel combustion engine. The ignition source of dual-fuel combustion was biodiesel derived from soybean oil. The premixing ratio was calculated based on the total input energy and was varied from 0.2 through 0.8. Experiments were conducted using a single cylinder diesel engine with a re-entrant geometry type combustion chamber.
