AN original definition of a four-stroke Diesel-engine is given by the author, who then presents a short history of high-speed Diesel-engine development which includes mention of the main features of the following engines: Junkers, Attendu, Sperry, Beardmore, Hindilmeier, Lang, Benz, M. A. N., Maybach, Peugeot, and others. The engineering problems relating to Diesel engines for automotive use are then discussed, with emphasis on the factors of atomization and distribution of the fuel in the air-charge, turbulence and airless fuel-injection, including types of igniter suitable for engines equipped with an antechamber.As to the possibilities of the oil-burning engine in the automotive field, the author says that the two main advantages it offers are reduced fuel-cost and reduced fire-hazards and that its chances are greatest wherever these are important factors. He believes that this type of engine will not come into use on passenger-cars within a reasonably short time since fuel cost contributes only a small fraction to the operating cost of a passenger-car and its fire hazard is almost negligible. Reduction in fuel cost for motor rail-cars that are equipped with an oil-burning engine will have a beneficial effect on net earnings and, if the problem of a suitable transmission can be solved, this field seems clear for engines of that type and they may be developed further so as to become available for smaller vehicles. Such engines already seem suitable for heavy motor-trucks in services where high speeds can be maintained over long periods.Following the paper, a brief summary of the advantages and disadvantages of the Diesel engine for automotive purposes is made by W. G. Wall, consulting engineer.AN original definition of a four-stroke Diesel-engine is given by the author, who then presents a short history of high-speed Diesel-engine development which includes mention of the main features of the following engines: Junkers, Attendu, Sperry, Beardmore, Hindilmeier, Lang, Benz, M.
