C4.4
Caterpillar
The Cat C4.4 is a versatile and high-performance 4-cylinder diesel engine renowned for its durability, fuel efficiency, and low emissions . Designed to meet rigorous global emission standards, it delivers reliable power across a wide range of demanding industrial, construction, and agricultural applications .
The Cat C4.4 engine powers a diverse portfolio of machinery, including:
Construction & Earthmoving Equipment: Excavators (e.g., 5-8 ton class), loaders, compactors, rollers, asphalt pavers, and trenchers.
Agricultural Machinery: Tractors, combines, harvesters, sprayers, and irrigation pumps.
Power Generation: Prime and standby diesel generator sets for facilities like hospitals and data centers.
Industrial Applications: Pumps, compressors, drill rigs, chippers, grinders, and hydraulic power units.
Modular & Compact Design: The engine features a modular core that significantly reduces its installation footprint. Compared to larger 5-liter platforms, it offers up to a 20% reduction in length and 40% reduction in weight, making it ideal for equipment with tight engine compartments.
Advanced Clean Emissions Technology: To meet stringent global emission standards, the engine utilizes an integrated aftertreatment system (DOC+DPF+SCR) that enables passive regeneration. This design minimizes operator intervention and helps maintain maximum uptime.
Intelligent Electronic Control System: A full-authority electronic control module and a high-pressure common rail fuel system ensure precise fuel delivery, optimal performance, and enhanced fuel economy across various duty cycles.
Low Total Operating Costs: The engine is engineered for efficiency, consuming over 18% less fluid than comparable 6-cylinder platforms. Combined with extended service intervals (e.g., 500-hour oil change) and global Cat dealer support, it helps lower the total cost of ownership.
