C4.4
Cat® C4.4 Diesel Engine
The Cat® C4.4 Industrial Diesel Engine is offered in ratings ranging from 82-150 bkW (109-200 bhp) @ 2200 rpm, which meet U.S. EPA Tier 4 Final, EU Stage V emission standards. Industries and applications powered by C4.4 engines include: Agriculture, Aerial Lifts, Aircraft Ground Support, Bore/Drill Rigs, Chippers/Grinders, Compactors/Rollers, Compressors, Construction, Cranes, Crushers, Feller Bunchers, Forestry, Forklifts, General Industrial, Harvesters, Hydraulic Power Units, Irrigation Equipment, Loaders/Forwarders, Material Handling, Mining, Mobile Earthmoving Equipment, Mobile Sweepers, Paving Equipment, Pumps, Skidders, Specialty Ag Equipment, Sprayers, Trenchers, Turf and Landscaping and Underground Mining Equipment.
Installation
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.
Advanced Features
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.
Ideal Applications
Industrial, agricultural and construction applications such as: Pumps • Compressors • Chippers • Grinders • Asphalt paving equipment • Hydraulic power units • Bore rigs • Drill rigs • Tractors.
Total Cost of Ownership
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.
Cat Dealer Product Support
The Cat C4.4 makes maintenance and service routines simple thanks to the worldwide Cat dealer network support. And for even more peace of mind, your Cat engine comes under warranty. See your Cat dealer for details.
Safety
Built-in clean emissions modules keep the Cat C4.4 performing at its peak while also keeping the air around the work site cleaner.
