diesel fuel with 15 ppm of sulfur or less) or ULSD blended with
the following lower-carbon intensity fuels up to: 20% biodiesel
FAME (fatty acid methyl ester)* or 100% renewable diesel, HVO
(hydrogenated vegetable oil) and GTL (gas-to-liquid) fuels. Refer
to guidelines for successful application. Please consult your
Cat dealer or “Caterpillar Machine Fluids Recommendations”
(SEBU6250) for details.
• Cat Grade with Slope Assist helps you avoid costly rework and
wasteful fuel burn and greenhouse gas emissions by automating
your blade position without a GPS signal.
• Cat Grade with 3D automates blade movements using a GPS signal,
helping you follow a grade design and reducing fuel burn and
greenhouse gas emissions by improving efficiency and accuracy.
• AutoCarry automates blade lift to reduce track slip for maximum
efficiency on each pass to help lower fuel burn and greenhouse gas
emissions.
• VisionLink displays the CO 2 emissions for monitored assets,
calculated by fuel type for the runtime fuel burned each day in a
selected date range.
• Remote Flash minimizes downtime and maintenance time while
keeping your asset running with maximum efficiency. Alerts
for machine updates are sent virtually from your Cat dealer and
updates can be deployed without a dealer technician needing to be
onsite.
• Read/Write Remote Troubleshoot decreases maintenance time and
keeps your machine running with maximum efficiency by allowing
your Cat dealer to virtually test the machine while working. Once
a problem is identified, a technician can fix it the first time, saving
time and money.
Productivity, fuel, and CO2 emissions vary by application. CO2 emissions
calculations based on a reference work cycle using 2.2 U.S. gallons
per hour of #2 U.S. diesel fuel. Applies IPCC2006 methodology using
U.S. EPA Emissions Hub emission factors. Includes DEF related CO2.
Fuel measurements are at 15°C. Estimated average fuel consumption
improvements are based on tests or Product Link data where available.
Productivity improvements are based on test data.
*Engines with no aftertreatment devices can use higher blends, up to
100% biodiesel.
