Idling
Idle speed is adjustable on Cat electronic engines. Consult your Cat dealer for information. The idle rpm is preset between 700 and 800 rpm.Avoid excess idling. An engine can burn from 2.8 L (0.7 US gal) to 5.7 L (1.5 US gal) of fuel per hour while the engine is idling. Excessive idling causes carbon buildup, engine slobber and soot loading of the diesel particulate filter (DPF).If extended idle time is required, control the engine rpm to 1000 rpm or above 1000 rpm. Ensure that the coolant temperature exceeds 82° C (180° F). Consult your Cat dealer for assistance.Fast idle can be programmed within the range of 700 rpm to the top engine limit. Fast idle requires an "ON/OFF" switch on the dashboard. Consult your Cat dealer for assistance.Idle Shutdown Timer
The idle shutdown timer can be programmed in order to shut down the engine after a specific time period of idling. The idle time can be programmed from 3 minutes to 1440 minutes (24 hours). If the idle shutdown timer is set to 0 minutes, the idle shutdown feature is disabled. If the setting of the timer is unknown, allow the engine to idle. Observe the time that elapses before the engine shuts down. The following conditions must be met in order to activate the idle shutdown timer:
The idle shutdown feature must be selected.
No vehicle speed is detected by the Electronic Control Module (ECM).
The engine is not under load.
The engine is at operating temperature.After the vehicle is stationary, the idle shutdown timer begins. The engine can be operating at low idle or at an idle rpm that is selected by the idle governor. The "CHECK ENGINE/DIAGNOSTIC" lamp will flash rapidly for 90 seconds prior to shutdown. Movement of the vehicle automatically resets the idle shutdown timer to the programmed setting.The following conditions must be met in order to override the idle shutdown timer:
Program the "ALLOW IDLE SHUTDOWN OVERRIDE" to "YES".
The "CHECK ENGINE/DIAGNOSTIC" lamp will flash rapidly for 90 seconds prior to shutdown. Depress the service brake or the clutch pedal during the 90 seconds when the "CHECK ENGINE/DIAGNOSTIC" lamp flashes. After an idle shutdown, the engine can be restarted without turning the ignition switch to the OFF position.The override function is disabled if the "ALLOW IDLE SHUTDOWN OVERRIDE" is programmed to "NO".Getting Started
Cat electronic engines do not require long warm-up periods that needlessly waste fuel. Typically, the engine should be at normal operating temperature in a few minutes. Begin operating the engine at low load. After normal oil pressure is reached and the temperature gauges begin to rise, the engine may be operated at full load.To get the vehicle in motion, use a gear that will result in a smooth start. Move the load without increasing the engine rpm above low idle or without slipping the clutch. Engage the clutch smoothly. Slipping the clutch and engaging the clutch can cause stress to occur on the drive train and can also cause fuel to be wasted.Use progressive shifting techniques. Progressive shifting is using only the rpm that is required in order to upshift into the next gear. Progressive shifting improves fuel economy.
Keep the engine rpm to a minimum. Use an rpm that is from 1400 to 2000 rpm.
Use only enough rpm to pick up the next gear.Progressive shifting also reduces the acceleration rate. Top gear is reached sooner because less time is needed to synchronize the gears during shifting. In addition, the engine is operating at the highest range of torque.The amount of rpm that is required to upshift increases as the vehicle speed increases, unless upshifts are made on upgrades. Experience with the vehicle will show the amount of rpm that is required to upshift under various conditions.Note: These engines may be programmed to encourage progressive shifting. The acceleration rate may slow down at certain rpm in lower gears. If this occurs, progressive shift parameters may have been programmed into the ECM. Progressive shift parameters will limit the rpm when the vehicle is driven in higher gears. These parameters may be protected by customer passwords. If the vehicle can be operated in a higher gear at a vehicle speed that is desired, select the highest gear that is available to pull the load. This recommendation will help to obtain fuel economy. The engine will be operating at the lowest rpm that is required to pull the load.Vehicle Efficiency
An efficient vehicle performs the desired amount of work while the power demand on the engine is minimized. The following factors are major contributors to power demand:
Aerodynamic drag (wind resistance)
Rolling resistance of the tires
Gross weight of the vehicle
Losses in the drive train and the load from the engine driven accessoriesFor more information about vehicle efficiency, refer to Special Publication, LEDT2254, "CAT Answers Your Questions About Truck Performance".Fuel Economy
Fuel is the largest single operating cost for on-highway vehicle engines. Improved fuel economy can have a substantial impact on operating profit. The following items are the most significant factors that influence vehicle fuel economy:
Driver techniques
Vehicle efficiency
Operating conditions
Engine efficiencyA No. 1 grade of fuel contains less energy per volume and increases fuel consumption. A greater volume of fuel must be injected in order to yield the same amount of work as a No. 2 fuel. The difference in the fuel economy between the two grades of fuel can be as great as 0.2 km/L (0.5 mpg) to 0.3 km/L (0.7 mpg). Refer to this Operation and Maintenance Manual, "Refill Capacities and Recommendations" or to this Operation and Maintenance Manual, "Fluid Recommendations" for information about the Ultralow Sulfur Diesel fuel (ULSD) that is required for this engine.For more information about fuel economy, refer to Special Publication, LEDT2254, "CAT Answers Your Questions About Truck Performance".Rolling hills provide a great opportunity to reduce fuel consumption. Avoid downshifting on small hills. The vehicle should not be downshifted even if the engine must be lugged down to an rpm that is below the peak torque rpm. When the vehicle is going down a hill, use gravity instead of the
