Overview

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, Underground Mining Equipment. C1.1 engines, with ratings: 14.4-18.4 bkW (19.3-24.7 bhp) @ 1800-2800 rpm, meet U.S. EPA Tier 4 Final emission standards. Ratings: 13.7-21.0 bkW (18.4-28.2 bhp) @ 2200-3000 rpm are available for Europe and, depending on applicable emission standards, may be introduced in other regulated areas. Nonroad engines less than 19 kW (25 hp) are not currently subject to EU emission standards. This information about Emissions describes the particular rating's emissions technology. For more information about emissions certification, please contact your local Cat dealer.

Reliable, Quiet, and Durable Power

The introduction of a simple electronic governor system for Tier 4 Final gives customers the flexibility of electronic machine integration if needed.

Package Size

No change to the core engine or hook up points and a high level of component commonality from Tier 4 Interim to Tier 4 Final, results in minimum equipment change and development costs to upgrade to Tier 4 Final, as well as common equipment configurations for export markets.

Low Cost Maintenance

Single-side servicing improves ease of maintenance and simplifies the servicing routine. Standard 500 hour service intervals.

Quality

Every Cat engine is manufactured to stringent quality standards in order to assure customer satisfaction.
