    Abstract : The potential and limitations of the Homogeneous Charge Compression Ignition (HCCI) engine concept has been experimentally investigated. The operation range, in terms of usable air/fuel ratio and engine load, and the emission characteristics have been studied. An 1. READ MORE

  3. 3. Experimental Investigations of Combustion Chamber Heat Transfer in a Light-Duty Diesel Engine

    University dissertation from Department of Energy Sciences, Lund University

    Author : Jessica Dahlström; Lund University.; Lunds universitet.; [2016-06-03]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; internal combustion engines; heat transfer; diesel engine; Diesel combustion; combustion chamber geometry; piston geometry; spray parameters;

    Abstract : This work concerned experimental studies of heat transfer in a light-duty diesel engine. Combustion is affected by several parameters, such as pressure, engine speed, mass of injected fuel and in-cylinder gas flow. These parameters are in turn affected by the combustion chamber geometry and fuel spray characteristics. READ MORE
