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

    Author : Jessica Dahlström; Förbränningsmotorer; []
    Keywords : 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
