Vabill, The torque curve of a typical diesel engine peaks ahead of, but fairly close to its full rated RPM, also called the high-idle speed or maximum governed speed. Because of this fact, it is common to hear folks say that the diesel is most efficient running at full speed. However, like any other engine, the fuel delivery and engine speed should be adjusted as needed to meet engine loads. There is no reason to run a diesel at full speed, (say to pull a cultivator) and then have to shift the transmission into low range to maintain the desired ground speed. If the engine can handle the load at lower speeds, then run it at lower speeds. As the other post said--you should never lug a diesel--that is, overload it at low RPM's to a point where black smoking and fuel knocking occurs. This condition places tremendous loads on engine bearings (rods, mains and wrist pins) and also causes excessive combustion pressures. Increasing the throttle at low RPM and high loads simply dumps more fuel into the engine and increased pressures result along with possible engine damage.
