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.

C1.1 Tier 4 Diesel Engines - Highly Regulated

Features

  • 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.
