Diesel Engine Speed:

Knowing how diesel engines are controlled and the categories of protective instrumentation available is significant for a complete understanding of the operation of a diesel engine.

DESCRIBES how the mechanical-hydraulic governor on a diesel engine controls engine speed.

LIST five protective alarms commonly found on mid-sized and larger diesel engines.

Engine Control

The control of a diesel engine is accomplished by various elements: the fuel injector, the camshaft, and the governor. The camshaft gives the timing required to properly inject the fuel, a fuel injector gives the elements in which meters and injects the fuel, and a governor regulates the amount of fuel in which the injector is to inject. Both, these three main elements ensure in which the engine runs at the desired speed.
