Information:
The standard engine includes the features of programmable low idle and top engine limiting (TEL). Cruise control, PTO governing, vehicle speed limiting, low and high gears engine rpm limiting (progressive shift control), retarder coast/latch and idle shutdown timer are also available depending on OEM truck configurations.If equipped, the 3176 engine system is capable of being programmed for several customer specified parameters. These parameters are generally programmed so the vehicle will achieve optimum fuel efficiency and operator convenience.Low idle and top engine rpm limits are customer programmable to promote maximum fuel efficiency. The 3176 system allows the owner to select power ratings within a "family" to more efficiently match the vehicle to the application.The customer specified parameters and a brief explanation of each are as follows:1. Engine Power Rating - The 3176 engine is designed to provide full rated power over a large range of engine speeds. For example, the Caterpillar 3176 ATAAC Truck Engine ratings for the 19911 are:* 250 hp (187 kW) @ 1800 rpm* 275 hp (205 kW) @ 1800 rpm* 300 hp (224 kW) @ 1800 rpm* 325 hp (242 kW) @ 1800 rpm* 250 hp (187 kW) @ 2100 rpm* 275 hp (205 kW) @ 2100 rpm* 300 hp (224 kW) @ 2100 rpm* 325 hp (242 kW) @ 2100 rpm1These ratings are available factory-set from Caterpillar, they are EPA, CARB (50-state) and Canada emission certified. Other ratings may be programmed either at the OEM or in the field.2. Vehicle Identification Number - The owner's description, or unit number of the vehicle. 3. PTO Vehicle Speed Limit (PTO VSL) - Maximum vehicle speed at which the PTO Governor will function.4. PTO Engine RPM Limit (PTO RPM) - Maximum engine rpm attainable using the CRUISE CONTROL switches while the vehicle is operated below the PTO VSL (generally used for maximum rpm limit for overnight idling). 5. Low Gears #1 RPM Limit (LoGr #1) - The rpm at which the engine is limited in the lowest gears.6. Low Gears #2 RPM Limit (LoGr #2) - The rpm at which the engine is limited in a secondary gear range.7. Low Gears Turn Off Speed (LoGr Off Limits) - The vehicle speeds at which LoGr #1 and LoGr #2 turn off. 8. High Gears rpm Limit (HiGr rpm) - The rpm at which the engine is limited in the higher gears (generally used to encourage shifting into higher gears).9. High Gear Turn On Speed (HiGr On) - The vehicle speed at which High Gear rpm is in effect.10. Top Engine Limit (TEL) - Maximum allowable engine rpm generally set at rated rpm [rpm at which maximum power is developed] plus (+) 20 rpm. 11. Engine rpm at Vehicle Speed Limit (Eng rpm at VSL) - The engine rpm achieved in high (top) gear at VSL. Interruption of the vehicle speed input to the 3176 System will limit engine rpm to this value at all vehicle speeds.12. Vehicle Speed Limit (VSL) - Maximum vehicle speed.13. Low Engine Idle rpm
