VISCOSITY OF DIESEL ENGINE FUEL OIL UNDER PRESSURE.
By Mayo D. Hersey.**
In the development of Diesel engine fuel injection systems
it is necessary to have an approximate knowledge of the absolute
viscosity of the fuel oil under high hydrostatic pressures.
This report has been prepared by the Special Research Committee
on Lubrication of the American Society of Mechanical Engineers
at the request of the National Advisory Committee for Aeronau-
tics, and presents the results of experimental tests conducted
by Mr. Jackson Newton Shore,* utilizing the A.S.M.E. high pres-
sure equipment which had previously been described in a paper
(Reference 1) by Mayo D. Hersey' and Henry Shore.***
Experimental Method
Reference should be made to the paper cited (Reference 1)
for a detailed description of the apparatus used. The viscom-
eter itself is of the rolling ball type originally due to Dr.
Alan E. Flowers.**** The pump, leakproof fittings and other
high pressure equipment are similar to those originally devel-
oped by Professor P. W. Bridgman of Harvard University.
