Caterpillar reported the 797F hauler is available in a Tier 4 Final-compliant configuration. The updated hauler is equipped with an exhaust after treatment system featuring selective catalytic reduction, which uses diesel-exhaust fluid to lower NOx emissions. The after treatment system uses less than 11% new content, Cat reported. The Tier 4 Final 797F reduces total specific fluid-consumption costs in most applications. The 797F is powered by the 4,000-hp (2,983-kW) Cat C175-20 engine, available with optimized fuel maps. It delivers class-leading payload and speed-ongrade performance, Cat reported.
