CONTEMPORARY EUROPEAN AIRCOOLED DIESEL-ENGINE PRACTICE

DURING World War II urgent military needs led to the rapid development of aircooled diesel engines. Specifications required that these engines, usually with one or two cylinders and a maximum speed of 1750 rpm, should be independent of water supply, should work under extreme climatic conditions, and should function with minimum maintenance.

This development is described in this paper, with particular reference to England and the Continent. The author points out that aircooled diesel engines are being successfully built in Europe to meet a wide variety of automotive and industrial uses. Cooling problems appear to have been satisfactorily solved. The author concludes with a comparison of liquid-cooled and aircooled engines.
