The engines discussed in this paper are the result of design decisions made as early as 1950. At that time, selecting “square” cylinder dimensions for an air cooled diesel engine was a radical departure from established practice, as was the decision to design an industrial diesel engine which would operate continuously at 3000 rpm, a synchronous speed for 50 cycle alternators. To achieve cold-start ability, low fuel consumption, low manufacturing cost and reliability at the high operating speed, it was necessary to develop a new combustion system which, although of the direct-injection type, operates with a single-hole nozzle. The desired goal was reached and the engines have been in large scale production for several years. This paper reviews the design approach as well as the development work that led to the final product, which is about as light and as compact as a modem gasoline engine of the same piston displacement.
