Benefits and Features

A modular and compact core on the Cat C4.4 makes installing the engine on any number of machine applications a relative breeze. And when downsizing from five-liter platforms, OEMs can see a 20% reduction in length, 5% reduction in height and 40% reduction in weight of the engine, significantly reducing installation costs.

With a 15% increase in power density and 10% increase in torque when compared to its predcessor engine, the compact design of the Cat C4.4 reduces heat loss for more efficient engine output, so operators can conquer even the toughest tasks with relative ease.

Industrial, agricultural and construction applications such as: Pumps • Compressors • Chippers • Grinders • Asphalt paving equipment • Hydraulic power units • Bore rigs • Drill rigs • Tractors.

There's a lot that can affect the lifetime cost of ownership on your engine. It can be as simple as fluid intake and as complex as weight distribution. Either way, the Cat C4.4 has it covered. When compared to similar 6-cylinder plaforms, the C4.4 saves more than 18% in fluid consumption and is specially balanced to be its most effective, every day.

The Cat C4.4 make maintenance and service routines simple thanks to scheduled maintenance and worldwide dealer support. Cat engine owners can also enjoy the peace of mind engine a five-year warranty brings.

Built-in clean emissions modules keep the Cat C4.4 performing at its peak while also keeping the air around the work site cleaner.
