Engine
Spec Value Net Power - ISO 9249 172 hp Net Power - ISO 9249 (DIN) 175 hp (metric) Engine Model Cat® C7.1 Engine Power - ISO 14396 174 hp Engine Power - ISO 14396 (DIN) 176 hp (metric) Bore 4 in Stroke 5 in Displacement 428 in³ Biodiesel Capability Up to B20¹ Emissions Meets U.S. EPA Tier 4 Final, EU Stage V, and 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 2,200 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. -
