ABSTRACT:
The maximum speed in an internal combustion engine is limited by circuitry which can be adjusted to conditions requiring a lower-than-normal top speed, for example during initial delivery to the customer and during the break-in period of the engine. The top speed limiter includes a comparator for suppressing or altering the fuel injection pulses. As a feature of the invention, the reference signal applied to the comparator and representing the top engine speed can be changed either manually or on the basis of elapsed time or mileage.
