Cat?� C4.4 Diesel Engine

C4.4 China Nonroad IV engine with aftertreatment

DESCRIPTION

The Cat?� C4.4 industrial diesel engine is offered in ratings ranging from 110-129.4 kW (147.5-173.5 hp) @ 2200 rpm, which meet China Nonroad Stage IV emission standards. The C4.4 is designed to meet the needs of many industries and applications, including bore/drill rigs, chippers/grinders, material handling, mining, earthmoving equipment, paving equipment, pumps, fruit harvesters equipment, turf and underground mining equipment.Cat?� C4.4 industrial diesel engines offer the perfect balance of durability, fuel efficiency and low emissions. Extensively tested on the job, these engines use a range of common rail fuel systems and advanced control systems to deliver maximum uptime in the harshest environment. They have proven they can handle the toughest applications and deliver superior performance that exceeds the expectations of the most demanding users. Industries and applications powered by C4.4 engines include: bore/drill rigs, chippers/grinders, material handling, mining, earthmoving equipment, paving equipment, pumps, fruit harvesters equipment, turf and underground mining equipmentIndustrial Power

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 20% increase in power density and 30% 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 of 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.
