Design Developments in European Automotive Diesel Engines 370172

A GENERAL consideration of the particular factors which define the development of the compression-ignition engine for automotive as apart from other purposes is presented in this paper.
The various combustion systems, their respective merits, and individual characteristics in the light of the particular conditions set forth previously are reviewed.
The evolution of the general mechanical design is traced, as resulting from the requirements of the particular duty, and from experience gained under prolonged service conditions, including a survey of the most prevalent troubles and difficulties and of measures which have proved effective in overcoming them.
The paper also discusses some economic aspects of compression-ignition engine operation, and the effects of such artificial factors as fuel taxation and the distribution of suitable fuels on design and on the choice of a combustion system.
A general survey of the present uses of the high-speed oil engine for automotive purposes in Europe, including railcar developments and likely future trends, concludes the paper.
