THE AUTHOR compares aircooled and liquid-cooled diesel engines from the several points of view, including: Plumbing difficulties, antifreeze requirements, bulk (hp per cu ft), weight (lb per hp), fan power and quantity of cooling air required, noise, costs, operation and maintenance.
Present-day aircooled diesel engines can be divided into four categories: those for industrial installations, small sized engines for agricultural applications, medium sized multipurpose engines, and large engines for military uses. Several examples of each type are discussed.
The author reports that because of their advantages in space utilization and adaptability to a wide range of temperatures, the aircooled engine is coming into greater and greater use.
