Cummins QSB6.7 Engine
This engine is used in every type of construction equipment, including excavators, cranes, wheel loaders, compactors, air compressors and material-handling equipment such as heavy forklifts and container-handling trucks. It is commonly found in agricultural tractors and sprayers, as well as chippers and feller bunchers in the logging market.
The Cummins QSB6.7 Engine (Tier 4 Final/Stage IV) is a powerful and reliable engine designed to meet the stringent emissions standards of Tier 4 Final/Stage IV. With advanced technology and innovative engineering, this engine delivers superior performance and efficiency for a wide range of applications.
This total integration of the engine and the exhaust system allows us to optimize fuel economy above the 5 percent we've already achieved with Tier 4 Interim engines, while achieving near-zero emissions at the same time.
The Cummins QSB6.7 Engine Parts are designed to provide exceptional durability and reliability, ensuring long-lasting performance in even the most demanding conditions. From the high-pressure common rail fuel system to the advanced air handling system, every component is engineered to deliver maximum power and efficiency.
Features and Benefits
Fully Integrated Electronic Controls. A single, higher-capacity Electronic Control Module (ECM) controls everything from air intake to exhaust aftertreatment for peak performance. Provides seamless integration of all components to optimize engine performance.
High-Pressure Common-Rail Fuel Systems. The high-pressure common-rail fuel system on the QSB6.7 delivers a precise mixture of fuel and air at a constant pressure, regardless of engine rpm. This flexibility in injection timing allows multiple injection events per cycle. In addition to increasing power output and lowering fuel consumption, this fuel systems reduce noise and engine vibration.
Fleetguard® Fuel Filters. These engines are equipped with Cummins Fleetguard fuel filters featuring nanotechnology-based media, designed to remove 98.7 percent of all particles as small as 4 microns, which is up to 13 times more than competing filters.
Direct Flow™ Air System. From Cummins Filtration – designed for Tier 4 installations to take less space, provide better protection and extend filter change intervals. Flat profile enables more efficient direct flow of air through the filter compared with conventional radial seal filters.
Cooled Exhaust Gas Recirculation (EGR). Rebalanced for Tier 4 Final, this cooled EGR system reduces demand on the engine, improving fuel efficiency and lowering cost of operation as it reduces fuel consumption and greenhouse gas emissions.
Cummins VGT™ Turbocharger. It has fewer moving parts than competitive turbochargers yet is infinitely adjustable – delivering the exact amount of air to the combustion chamber with the precision of electronic controls.
EcoFit™ Ultra-Low Emission Systems. Introduced by Cummins Emission Solutions, EcoFit Ultra-Low Emission Systems for the QSB6.7 utilize innovative aftertreatment technologies designed to improve equipment performance and integration with a more compact and flexible installation for Tier 4 Final.
