Information:
The 3176 Engine governor functions like a mechanical governor in the mid speed operating range. There is some droop to provide good driver feel. The 3176 governor has a programmable low idle rpm of 600 to 750 rpm, regardless of load.This low idle feature makes it easier to start a loaded truck on a steep grade. The governor eliminates most of the overrun at high idle that is experienced with a mechanical governor.Proper operation and maintenance are key factors in obtaining the maximum life and economy of the 3176 truck engine. Following the directions in this manual will lower operating costs.Cold Mode Operation
The 3176 system automatically idles the engine at 1000 rpm for the correct warm up time after a cold engine start [approximately less than 40°F (5°C)]. The 3176 system periodically checks the engine coolant temperature sensor and will reduce the idle speed to programmed low idle speed when the engine is warm enough to drive the truck.The time needed for the engine to reach the normal mode of operation is usually less than the time taken for a walk-around-inspection of the vehicle.
A truck equipped with a 3176 Engine should not be driven until it is out of the cold mode. If the engine speed is not controlled by the PTO governor function while in the cold mode, the engine idle will be reducedto programmed low idle automatically when the cold mode is completed.
After the engine is started and the cold mode operation is completed, the truck can be operated at low speed and low power. The engine will reach normal operating temperature faster when driven at low speed and low power demand than when idled at no load. Typically the engine should be up to operating temperature by just driving through the yard toward the open road.Engine Operation
* Begin operating the engine at low load. After normal oil pressure is reached and the temperature gauge begins to move, the engine may be operated at full load.* To get the vehicle in motion, use a gear that will result in a smooth, easy start without increasing engine speed above low idle or slipping the clutch. Engage the clutch smoothly. Abrupt or jerky starts put excessive stress on the drive train and waste fuel. It is not necessary to advance the throttle to get the 3176 equipped truck moving from a stop in most instances.* Use progressive shifting to reduce fuel consumption. Progressive shifting is using only enough engine rpm required to make an upshift into the next gear. (The amount of engine rpm required to make an upshift increases as the truck speed increases, unless upshifts are made on upgrades.) Experience with your truck will show you how much engine rpm is required to make upshifts under various conditions. Your 3176 engine may be programmed for Low and High Gears RPM Limiting (progressive shift control).* If the truck can be operated in a higher gear after the desired speed is reached, select the highest gear available that
