QSB6.7 engines range from 146-310 hp (109-231 kW) for Tier 4 Final. They have the same heat rejection as the Tier 4 Interim engines, so there is minimal, if any, impact on the cooling package. The QSB6.7 is one of the most popular and versatile engines ever built by Cummins.



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.



All of the performance upgrades from Tier 4 Interim have been incorporated into the Tier 4 Final engines, and we're maximizing torque output, reaching 760 lb-ft (1030 N•m) on the QSB6.7.
