SUSTAINABILITY

The Cat® C3.3B engine meets U.S. EPA Tier 4 Final, EU Stage V, and Japan 2014 emission standards.
Cat diesel engines are required to use ULSD (ultra-low sulfur 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 (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.
Auto Idle helps reduce unnecessary fuel burn and greenhouse gas emissions by allowing the engine to automatically go into idle mode when the machine is not working.
Engine Idle Shutdown Timer reduces fuel burn, greenhouse gas emissions and unnecessary idle time by shutting down the machine after a pre-set idling period.
Cruise control helps you maintain a constant speed as you travel across your jobsite saving fuel and reducing greenhouse gas emissions.
The Cat® Seat Belt Reminder provides audible and visual warnings to remind operators to buckle up during machine operation. The easy-to-install system is compatible with all equipment brands to help ensure operator safety.
Extended maintenance intervals not only reduce downtime but decrease the amount of fluid and filters that are replaced over the life of the machine.
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.(if equipped)
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.(if equipped)
Cat Grade with advanced 2D and 3D technologies combine advanced guidance with optional automated machine control helping you reach grading targets while reducing fuel burn and greenhouse gas emissions by improving efficiency, job site productivity, and accuracy. (if equipped).

*Engines with no aftertreatment devices can use higher blends, up to 100% biodiesel. (for use of blends higher than 20% biodiesel, consult your Cat dealer)
