2. 1. 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. 2. 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

5. 3. Dual-Fuel Combustion in a Heavy-Duty Engine

   Author : Zhiqin Jia; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The need to control climate change and improve the fuel effieciency of internal combustion engines has prompted global efforts to develop alternative fuels in order to reduce dependence on conventional petroleum derivatives. This thesis deals with three such alternative fuels: compressed natural gas (CNG), pure methane (used to mimic biogas), and methanol. READ MORE

6. 4. HCCI Combustion - Engine Operation and Emission Characteristics

   Author : Magnus Christensen; Förbränningsmotorer; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Motorer; framdrivningssystem; Motors and propulsion systems; efficiency; emissions; combustion; HCCI; engine;

   Abstract : The potential and limitations of the Homogeneous Charge Compression Ignition (HCCI) engine concept has been experimentally investigated. The operation range, in terms of usable air/fuel ratio and engine load, and the emission characteristics have been studied. An 1. READ MORE

7. 5. Experimental Investigations on Natural Gas-Diesel Dual Fuel Combustion

   Author : Pablo Garcia; Förbränningsmotorer; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dual Fuel; Diesel; Natural Gas; Pilot Injection; Combustion Efficiency; Methane; Nitrogen Oxides; Lean operation; Ignition;

   Abstract : Natural gas has been traditionally applied in spark-ignited combustion engines due to similar combustion characteristics for methane gas and gasoline. However, spark ignition requires a low compression ratio to avoid knock problems and therefore, gas engines have lower efficiency than diesel engines. READ MORE
