  1. 1. Low Emission Concepts for Diesel Engines

    Författare :Arjan Helmantel; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; post injection; adjustable valve timing; two-colour pyrometry; Homogeneous Charge Compression Ignition; emissions; piezo injector; swirl; combustion; Diesel; HCCI; endoscope;

    Sammanfattning : In the recent past, the Diesel engine has been improved considerably in the areas of performance, fuel efficiency and exhaust emissions. In Europe, these improvements have resulted in a strong increase in the sales of passenger cars equipped with a Diesel engine. LÄS MER

  3. 2. THE EFFECTS OF VARIOUS NOZZLE HOLE CONFIGURATIONS ON DIESEL ENGINE PERFORMANCE

    Författare :Andreas Matsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diesel engine combustion non-circular nozzle hole cavitation hydrogrinding optical study flame wall interaction;

    Sammanfattning : Any improvement that can be done with the diesel engine to reduce emissions and fuel consumption is of importance. The aim of the studies presented in this thesis was to determine whether changes in the nozzle geometry of the fuel injection systems used in diesel engines might improve their emissions and fuel consumption.

  4. 3. Atomisation and Combustion Studies of Diesel Sprays

    Författare :Lionel Christopher Ganippa; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis addresses two potential problems facing investigators involved in Diesel engine development: fuel atomisation and soot formation. A particular concern has been cavitation in nozzles and its influence on the spray and combustion, investigated through impingement studies, scaled-up transparent nozzle studies and evaluation of hydro grinding effects in a real-size nozzle.
