Abstract
RADIOTRACERS were used to study the wear effects of engine speed, load, jacket water temperature, fuel temperature, and chromium-plated rings in a medium-speed diesel engine. One distillate fuel and two residual fuels were tested. This paper describes the tests and their results. Some of the conclusions are:
-
The brake thermal efficiency with high viscosity residual fuel was essentially equal to distillate diesel fuel over a wide range of loads, providing the residual fuel was heated to the proper temperature.
-
Engine speed did not affect the wear rate of cast-iron rings when distillate fuel was used, while with residual fuel wear decreased with increased speed.
-
With distillate fuel, engine load had essentially no effect on cast-iron ring wear. With residual fuel, decreasing engine load produced a marked increase in ring wear*
