Description / Abstract:
This document covers evaluation techniques for determining the
power consumption characteristics of engine driven hydraulic pumps
used on heavy-duty trucks and buses. The testing technique outlined
in this SAE Recommended Practice was developed as part of an
overall program for testing and evaluating fuel consumption of
heavy-duty trucks and buses. The technique outlined in this
document provides a description of the test to be run to determine
power consumption of these engine driven components, the type of
equipment and facilities which are generally required to perform
these tests are discussed in SAE J745. It is recommended that the
specific operating conditions suggested throughout the test be
carefully reviewed on the basis of actual data obtained on the
specific vehicle operation.
