  1. 1. Hollow cone gasoline/ethanol sprays under cold start conditions

    Author : Jonas Wärnberg; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SIDI; Cold start; PIV; Piezo-injector; PDA; Ethanol; SI; SGDI; E85; Direct injection stratified charge; LIF; Spark ignition; Mie;

    Abstract : To decrease the release of CO2 from fossil fuels into the atmosphere, within the transportation sector the efficiency of vehicles and their engines must be increased. Additionally renewable fuels may be used to further decrease our reliance on fossil fuels. READ MORE

  2. 2. Injection and Combustion of Alternative Fuels in Spark Ignited Direct Injection Engines

    Author : Lars Christian Riis Johansen; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gas fuel; direct injection; E85; stratified combustion; spark ignition; alternative fuels; optical measurements;

    Abstract : Increasingly stringent vehicle emission legislation necessitates increasingly efficient combustion engines. The use of direct injection in spark ignited engines improves engine efficiency and reduces CO2 emissions. READ MORE

  3. 3. Alcohol Flexible Dual-Fuel Direct Injection Engine

    Author : Michael Saccullo; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuel spray; Dual-fuel; Dual-direct injection; E85; Ethanol; Heavy duty engine; Diffusion combustion; Methanol;

    Abstract : Laws concerning emissions from HD internal combustion engines are becoming increasingly stringent in terms of local emissions and emissions concerning global warming such as lowering tailpipe CO2. New engine technologies are needed to satisfy these new requirements and to reduce fossil fuel dependency and increase renewable fuels in the transportation sector. READ MORE

  4. 4. Deactivation of commercial three-way catalysts: effect of the thermal ageing

    Author : Anna Fathali; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BET; methane production from E85; NOx reduction by methane; Rhodium; TWC; OSC; Automotive exhaust control; Palladium; Aging;

    Abstract : This licentiate thesis is a summary of my study on thermal deactivated commercial threeway catalysts (TWCs). The experiments were performed using gasoline and a E85 fuelmixture of 85 vol.% ethanol and 15 vol.% gasoline. READ MORE

  5. 5. Spark Ignition Combustion of Direct Injected Alternative Fuels

    Author : Lars Christian Riis Johansen; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; spark ignition; optical diagnostics; internal combustion engine; stratified combustion;

    Abstract : Several technologies and modifications exist to increase the fuel efficiency of passenger vehicles in general and spark ignition engines in particular. Combining a spark ignition engine with an electric drive system in hybrid powertrain and thermodynamic cycle improvements are two such approaches with the potential to greatly reduce fuel consumption.
