The 3161 is a mechanical governor designed for speed control for use predominantly on diesel engines. It was originally intended specifically for Caterpillar engines but is also used on some other types of diesel engine, mainly Wartsila.
The construction of the 3161 governor was based upon a simple design which would facilitate a number of changeover options which could easily be fitted on the governor lid assembly to suit customer requirements.
The 3161 operation can be isochronous for accurate constant speed or frequency control, or droop
for load sharing.
The options are as follows:
• Shutdown option energised to run or shutdown
• Manual shutdown
• Fuel limitation: pneumatic, mechanical or electrical solenoid
• Torque limitation
• Speeder motor control
• External droop adjustment
• Pneumatic speed control
• Manual level control
• Various terminal shaft designs
Output capacity ranges from 6 to 18 ft-lb.
The 3161 is also directly interchangeable with the UG8
