The Cat® 315 excavator offers excellent performance in a compact design. Standard, easy-to-use Cat technologies boost operator efficiencies and improve jobsite productivity while a large, ergonomic cab provides a comfortable working environment. Combined with simplified maintenance points, the 315 keeps you working, quickly and efficiently.
Engine Model | Cat C3.6 |
Biodiesel Capability | Up to B20¹ |
Emissions | Meets U.S. EPA Tier 4 Final, EU Stage V, Japan 2014 emission standards. |
Note (1) | Net power advertised is the power available at the flywheel when the engine is equipped with fan, air intake system, exhaust system and alternator with engine speed at 2,400 rpm. Advertised power is tested per the specified standard in effect at the time of manufacture. |
Note (2) | ¹Cat 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. * 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).** Tailpipe greenhouse gas emissions from lower-carbon intensity fuels are essentially the same as traditional fuels. |
