HEINZMANN governors are employed in the propulsion engines of most marine engine manufacturers worldwide. Available for both mechanical and electronic fuel injection, these controllers handle outputs of up to several thousands of kilowatts and cover all speed ranges. They can be used in main propulsion engines with and without controllable pitch propellers, multi-engine units on one shaft, drive units with shaft generators as well as diesel-electric drive units. Their high flexibility in terms of functional scope and interface design makes them the control solution of choice for original equipment as well as retrofitting. Speed setpoint and gearbox clutch control commands from a main propulsion bridge control unit can be processed directly. They are completed by a perfect choice of HEINZMANN actuators.
