  1. 1. Transient Air to Fuel Ratio Response in a Fuel Injected S.I Engine

    Author : Göran Almkvist; Chalmers University of Technology; []
    Keywords : dynamic; A F; model; transient; air to fuel; response; time constant; film; behavior; lambda; time-delay; fuel; mass; deposit factor;

    Abstract : Future emission standards make it necessary to focus on the conditions under which engine emissions are produced, especially before the catalyst light off. During practical driving conditions, such as those represented by the FTP 75 test cycle, the engine is operated very much under transient conditions regarding load and speed. READ MORE

  2. 2. Studies of a Heavy-Duty Diesel Aftertreatment System Based on the NOX Storage and Reduction Technology

    Author : Klaus Papadakis; Institutionen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fuel penalty; injection parameters; DoE; design of experiments; exhaust; diesel engine; NO oxidation; simulation; modelling; oxidation catalyst; NOX trap; NOX storage and reduction; NSR; Kemiteknik och kemisk teknologi; Chemical technology and engineering; dosing strategy; system optimisation;

    Abstract : The legislative limits for NOX emissions in the exhaust gas from heavy-duty diesel engines will be decreased in the European Union from today 3.5 g/kWh (Euro IV) to 2.0 g/kWh in 2008 (Euro V). In the USA and Japan a similar trend can be seen. READ MORE

  3. 3. Experimental Investigations on Natural Gas-Diesel Dual Fuel Combustion

    Author : Pablo Garcia; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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

  4. 4. Multiple Diesel Injections - Spray Behaviour and Fuel Injection System Dynamics

    Author : Rickard Ehleskog; Chalmers University of Technology; []

    Abstract : .... READ MORE

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

    Author : Michael Saccullo; Chalmers University of Technology; []
    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
