Cat® C1.1 Diesel Engine

C1.1 Tier 4 Diesel Engines - Highly Regulated

DESCRIPTION

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.The Cat® C1.1 Industrial Diesel Engine is offered in ratings ranging from 14.4-18.4 bkW (19.3-24.7 bhp) @ 1800-2800 rpm. These ratings meet U.S. EPA Tier 4 Final emission standards. Ratings: 13.7-21.0 bkW (18.4-28.2 bhp) @ 2200-3000 rpm are also 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. 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.Industrial Power

Reliable power

Manufactured in some of the world's most modern and highly-automated production facilities, the Cat® C1.1 is proven to deliver durable power and offers a wide range of customization options that refuse to compromise quality and durablity.

Compact size

With a 18.4 kW (24 hp) power rating, the C1.1 and the C1.1 turbo allows OEMs to consider different installation, operating and commercial requirements. These models are particularly adapted to machines where power from a small
package is crucial. And for jobs that require that extra bit of power, there's a turbocharged option that delivers in almost any condition, at any altitude.

Quiet work

The stiff block and indirect injection system in the C1.1 were built for quiet so worksites are safer, operators are less
fatigued and noise levels in regulated areas aren't exceeded.
