BE_LL, RESEARCH ENGINEER WRIGHT AERONAUTICAL CORPORATION In looking for a clew to successful engine lubrication, it is evident that type of circulating system cannot be selected. This statement is supported by two successful basic designs, namely: The Splash Circulating System Figure 1. The Force Feed System Figure 2. Several modifications of these systems need not be discussed here, for if basic design is not the answer, detailed modifications are only important if they all tend to affect the design to some common end. The lack of importance of basic design is emphasized by a brief comparison of engines, each retaining substantially similar lubricating system designs for a number of years, through a fairly wide range of horsepower and R.P.M. Data taken from the statistical issues of "Automotive Industries" show for similar cars manufactured by same factories in 1930 and 1936:- TABLE I. Car Displacement cu. in. B.H.P. at R.P.M.
