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.
