QSB6.7-C173
Cummins
The Cummins QSB6.7-C173 is a premium 6.7-liter, in-line six-cylinder diesel engine engineered to deliver a robust balance of power, durability, and fuel efficiency. Designed for demanding industrial and commercial use, this 173-horsepower (129 kW) engine leverages Cummins' advanced engineering to provide reliable performance in the toughest conditions, ensuring maximum uptime and a low total cost of ownership.
The QSB6.7-C173 is a versatile power source built for a wide array of heavy-duty equipment. Its primary applications span several critical industries:
Construction Machinery: Excavators, wheel loaders, bulldozers, and cranes.
Material Handling: Forklifts, container handlers, and heavy-duty forklifts.
Specialized Vehicles: Mining trucks, dump trucks, and airport ground support equipment.
Power Generation: Industrial generator sets for prime or standby power.
Agricultural Equipment: Large tractors and harvesters.
Advanced High-Pressure Common Rail (HPCR) Fuel System
At the heart of the engine is a Bosch High-Pressure Common Rail fuel system. This technology enables ultra-precise, multiple fuel injections per cycle, resulting in superior combustion efficiency. The benefits are excellent fuel economy, significantly reduced noise levels (up to 80% quieter at idle), and near smoke-free operation, all while meeting stringent Stage III emission standards without complex aftertreatment.
Optimized Engine Design for Performance
The engine features a turbocharged and aftercooled design for optimal air intake and power density. It is built with a robust 24-valve cylinder head that improves airflow and combustion efficiency. This design delivers strong low-end torque (873 N·m) for excellent lugging power and responsive acceleration under load.
Intelligent Electronic Control & Durability
Governed by a sophisticated Electronic Control Module (ECM), the engine allows for precise performance mapping, advanced diagnostics, and comprehensive engine protection. The robust construction, including key components like a forged steel crankshaft, ensures exceptional durability and long service life in challenging environments.
Global Support and Serviceability
Backed by Cummins' worldwide service network, operators benefit from readily available genuine parts and expert technical support. The engine's design incorporates service-friendly features, facilitating easier maintenance and minimizing downtime.
