We now offer a selection of governor motors for Kobelco®, Hitachi®, Komatsu®, and Hyundai®.
Engine Throttle Control System
The governor is one of the most critical components of a diesel engine, it controls the engine speed by limiting the amount of fuel delivered by the injection system. It is designed to maintain a constant engine speed regardless of load variation. CTP Governors provide reliable and precise control of engine speed and output in a large number of applications, from the smallest power generating stationary equipment, to the largest in heavy duty and marine applications. CTP offers a reliable solution to today’s demanding engine management systems.
