  1. 1. Engine Encapsulation for Increased Fuel Efficiency of Road Vehicles

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Blago Minovski; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coupled simulations; powertain cooling systems; warm-up; 1D simulations; thermal engine encapsulation; cool-down; fuel consumption; numerical analysis; 3D CFD simulations;

    Abstract : Thermal engine encapsulation is an increasingly popular design choice, which insulates the engine from the external environment and retains heat in the engine after it is turned off. This decelerates motor cool-down and increases the probability for high initial temperature at a subsequent engine start, resulting in shorter warm-up and reduced friction between engine parts.

  2. 2. Conceptual Design of Semi-Closed Oxy-Fuel Combustion Combind-Cycle

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Majed Sammak; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Oxy-fuel; Gas turbines; Combined Cycles;

    Abstract : Accelerating actions to mitigate CO2 emissions was one of the important messages at the UN Climate Summit 2014. About 85 % of the world’s energy is provided through the burning of fossil fuels, which is the main source of CO2 emissions. READ MORE

  3. 3. The open absorption system : energy savings in different applications

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Lars Johansson; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : The open absorption system is a technique that makes it possible to recover energy in different processes using moist air. In most applications the latent heat in moist air is difficult to recover because of the low temperature. Processes using outdoor air to carry away moisture therefore have high energy demands.

  4. 4. Tribology for Greener Combustion Engines Scuffing in Marine Engines and a Lubricating Boric Acid Fuel Additive

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Petra Olander; Staffan Jacobson; Roland Larsson; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Friction; wear; lubrication; energy loss; atmospheric emissions; fuel efficiency; transport.; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

    Abstract : This thesis aims at increased knowledge in two fields of tribological research; both related to making currently used combustion engines greener. The first field regards the possibilities of using a boric acid fuel additive to increase fuel efficiency. READ MORE

  5. 5. Experimental study of single fuel jet combustion and high-cycle regenerative systems

    University dissertation from Stockholm : Materialvetenskap

    Author : Simon Lille; [2002]
    Keywords : combustion; preheated air; energy savings;

    Abstract : High Temperature Air Combustion (HTAC) is a technique toreduce consumption of fuel and decrease NOxformation in furnaces. The main change that occursin the furnace chamber is that the flow pattern of flue gasesaltered resulting in a more uniform heat transfer andtemperature profile. READ MORE
