  2. 11. The efficient ethanol engine with cold start capability

    Author : Jonas Wärnberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Piezo-actuated outward-opening direct injection; SI engine; Two-stage-turbo charging; Ethanol; Stratified Direct Injection; Cold start;

    Abstract : In light of the world’s growing demand for personal transportation and the decreasing availability of fossil fuels, alternative fuels must be evaluated. Ethanol is a renewable fuel whose adoption could help to reduce the burden of anthropogenic activity on the environment. READ MORE

  4. 12. On Combustion in the CNG-Diesel Dual Fuel Engine

    Author : Fredrik Königsson; Hans-Erik Ångström; Helmut Eichlseder; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Design; Maskinkonstruktion;

    Abstract : Currently there is a large interest in alternative transport fuels. There are two underlying reasons for this interest: the desire to decrease the environmental impact of transports and the need to compensate for the declining availability of petroleum. In the light of both these factors, the CNG-diesel dual fuelengine is an attractive concept. READ MORE

  5. 13. Gasoline Engine HCCI Combustion - Extending the high load limit

    Author : Daniel Dahl; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NVO; stratified charge; gasoline engine; high load; knock.; HCCI; stoichiometric; CAI; ringing; SCCI;

    Abstract : There is an increasing global focus on reducing emissions of greenhouse gases.For the automotive industry this means reducing CO2 emissions of the vehiclesmanufactured, which is synonymous with reducing their fuel consumption oradapting them for using renewable fuels. READ MORE

  6. 14. Modeling and Control of EGR on Marine Two-Stroke Diesel Engines

    Author : Xavier Llamas; Lars Eriksson; Gerasimos Theotokatos; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modeling for control; Ship Propulsion; Dynamic Simulation; Exhaust Gas Recirculation; Mean Value Engine Model; Parameterization; Compressor; Model Extrapolation;

    Abstract : The international marine shipping industry is responsible for the transport of around 90% of the total world trade. Low-speed two-stroke diesel engines usually propel the largest trading ships. This engine type choice is mainly motivated by its high fuel efficiency and the capacity to burn cheap low-quality fuels.
