6BTA5.9
Cummins
Proven Power, Unmatched Reliability
The Cummins 6BTA5.9 is the benchmark for durability and performance in the mid-range diesel engine segment. As one of the most widely produced 6-liter diesel engines globally, it delivers a perfect balance of robust power, exceptional fuel economy, and legendary longevity. Built on a simple, time-tested mechanical design, this inline-6 cylinder engine provides dependable power for a vast array of demanding applications, from commercial marine propulsion to critical power generation and heavy-duty construction.
Here are the key specifications that define the 6BTA5.9 engine:
The 6BTA5.9 platform is engineered to excel across multiple industries:
Power Generation: A prime mover for dependable diesel generator sets. The 6BTA5.9-G2 model is renowned for providing prime and standby electrical power (e.g., 100kW-116kW output), ensuring continuity for industrial facilities, data centers, and commercial buildings.
Marine Propulsion: A cornerstone for commercial and recreational marine applications. Available in various horsepower ratings for propulsion and as a reliable marine auxiliary engine, trusted for its saltwater endurance.
Construction & Industrial Machinery: Delivers the tough, consistent torque needed for construction equipment like excavators, loaders, and compaction machinery. Models like the 6BTA5.9-C180 provide robust power (e.g., 132kW @ 2500 RPM) for heavy-duty cycles.
Vehicle & Miscellaneous: Also serves in medium-duty trucks, pump drives, and other specialized industrial equipment requiring a compact, high-torque power solution.
Robust Mechanical Design for Maximum Uptime: Built with approximately 40% fewer parts than comparable engines, the integrated design of the cylinder block and head minimizes potential leak points and drastically reduces the overall failure rate. This simplicity translates to easier maintenance and lower total cost of ownership.
Efficient Turbocharged and Intercooled Aspiration: The turbocharger, often a Holset model with an integrated wastegate valve, forces more air into the cylinders. Coupled with an aftercooler (water-air or air-air), it cools the intake charge for denser air, resulting in significantly improved power density, better fuel combustion, and lower emissions.
Durable Fuel and Combustion System: Equipped with a precise mechanical in-line fuel injection pump and governor, this system is celebrated for its reliability and serviceability across global markets. Features like platform honing on the cylinder liners and advanced piston ring technology work together to optimize oil control, reduce consumption, and extend engine life.
