Cummins

Product Description: Cummins B5.9-C Diesel Engine
Overview: Unmatched Reliability for Demanding Work
The Cummins B5.9-C is a cornerstone of the legendary B-Series engine family, offering robust, mechanical simplicity and proven durability for heavy-duty industrial applications. This inline 6-cylinder, 5.9-liter diesel engine is engineered for exceptional longevity and low total cost of ownership. With a power output ranging from 80 to 173 horsepower (60-129 kW), it delivers the dependable power needed to tackle the toughest jobs across multiple sectors, from construction sites to marine environments.
The B5.9-C engine is renowned for its versatility, serving as a trusted power source for a wide array of equipment:
Construction Machinery: Excavators, loaders, bulldozers, graders, and compactors.
Industrial Power Units: Pumps, compressors, and generator sets for oil & gas and general industry.
Marine Applications: Auxiliary power and propulsion for commercial and workboats.
Agricultural Equipment: Tractors and other high-duty-cycle farm machinery.
Legendary Unitized Design: The B5.9 engine platform utilizes an integrated, unitized design that incorporates approximately 40% fewer parts than traditional diesel engines. This simplicity drastically reduces potential failure points, enhances overall reliability, and simplifies maintenance, contributing to a famously long service life.
Heavy-Duty Engine Architecture: Built for endurance, key components include a forged steel crankshaft and camshaft for superior strength, and a robust parent-bore cylinder block engineered to handle high combustion pressures. Plateau-honed cylinder bores ensure optimal oil retention and near-zero oil consumption over time.
Efficient Air & Fuel Management: Equipped with Holset wastegated turbochargers (on turbo models) for optimized performance and improved torque response. The reliable mechanical inline or rotary fuel injection pump provides precise fuel delivery and is known for its durability and ease of service.
Operational Versatility: The engine platform is offered in multiple aspiration configurations (NA, T, TA) to suit specific power and application needs. Optional features like resistive grid heating enhance cold-start capability in harsh environments.
