Cat® C1.1 Diesel Engine

Cat® C1.1 Industrial Diesel Engines deliver impressive performance throughout a wide speed range with exceptional power density. Their ultra-compact package size and extensive choice of options ensures these engines are ideal for a wide range of small, off road applications. Single-side servicing improves ease of maintenance and lowers overall owner operating costs. Industries and applications powered by C1.1 engines include: Aircraft Ground Support, Auxiliary Power Units, Bore/Drill Rigs, Chippers/Grinders, Compactors/Rollers, Construction, Forestry, General Industrial, Material Handling, Mining, Mobile Earthmoving Equipment, Mobile Light Towers, Pumps, Trenchers and Underground Mining Equipment. C1.1 engines, with ratings: 13.7-21 bkW (18.4-28 bhp) @ 2200-3400 rpm, meet EPA Tier 4 Interim equivalent emission standards. They are available using U.S. EPA Flexibility and for Europe and, depending on applicable emission standards, may be introduced in other regulated and non-regulated areas. Nonroad engines less than 19 kW (25 hp) are not currently subject to EU emission standards.
