there is no radiator fan or water pump; there is no danger of the engine
boiling or freezing, and no maintenance of fan bearings, or water pumps; and
first cost is low.
In selecting an engine of this type, the initial step is to determine the
horsepower requirements of the driven load.
On equipment of entirely new design, it is often difficult to ascertain the
amount of power necessary. In such instances, a rough estimate of the
horsepower range (kW range) is made and one or more sample engines
bracketing the range obtained for use on experimental models of the
equipment.
