ABSTRACT:
The present invention relates generally to combustion engines, and more specifically, to an apparatus for controlling the power of combustion engines which have electrically-modulated throttle systems (also known as drive-by-wire throttle systems). There many applications in which it is desirable to modify the throttle control system of vehicles, for example, in limiting the power production of trucks operating in under ground mines. It is prohibitively expensive for vehicle manufactures to supply such modified vehicles, so a system must be provided and installed as an after market product. The invention provides a simple and inexpensive solution in the form of a voltage modifying device which can be installed inline, between the accelerator pedal sensor and the engine control unit. The voltage modifying device can be designed to limit the power of the engine, or alter the performance profile in a desired manner.
