- The Cat® C4.4 engine meets Brazil MAR-1 emission standards, equivalent to U.S. EPA Tier 3 and EU Stage IIIA.
- Cat engines are compatible with diesel fuel blended with the following lower-carbon intensity fuels* up to: 20% biodiesel FAME (fatty acid methyl ester) or 100% renewable diesel, HVO (hydrotreated 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.
- Extended maintenance intervals not only reduce downtime but decrease the amount of fluid and filters that are replaced over the life of the machine.
- Auto Engine Speed Control reduces fuel burn and greenhouse gas emissions by allowing the engine to automatically go into idle mode when the machine is not working. Consult your Cat dealer or the machine's operation and maintenance manual for more information.
*Tailpipe greenhouse gas emissions from lower-carbon intensity fuels are essentially the same as traditional fuels.
