  2. 16. A Combustion Concept for Future Heavy-Duty Diesel Engines

    Author : Tobias Husberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diesel combustion; Common rail; Diesel engines; Multiple injections; Combustion concept; Heavy-duty;

    Abstract : The Diesel engine has been intensively developed by manufacturers and researchers since 1892, when it was invented. However, the direction of its development has shifted in recent years.Environmental issues are becoming increasingly important in our society, prompting more efforts to be put into making the engines cleaner.
