  2. 6. Methanol Diesel Dual Fuel Direct Injection in a HD-CI Engine

    Author : Michael Saccullo; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alcohol Fuels; Heavy Duty Engine; Dual Fuel; Combustion;

    Abstract : Laws concerning emissions from heavy duty (HD) internal combustion engines are becoming increasingly stringent. New engine technologies are needed to satisfy these new requirements and to reduce fossil fuel dependency. READ MORE

  4. 7. Advancing the understanding of pilot ignition in dual fuel engines : Experimental and conceptual studies

    Author : Menno Merts; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combustion engines; Dual fuel; RCCI; Pilot injection; renewable fuels; Conceptual model; LTC; Heavy duty; Marine; Start of combustion; Optical engine research;

    Abstract : The energy transition is looking for new technologies to reduce CO2 emissions. One of the promising options is the dual fuel engine. In this concept, based on a diesel engine, a small pilot diesel injection is used to ignite a second fuel. READ MORE
