Applications- Agriculture, Construction, Mining Engines, Oil and Gas Engines, Rail Engines, Well Servicing
QSL9 engines are rated at 250-400 hp (186-298 kW) for Tier 4 Final. It has the same heat rejection as the Tier 4 Interim engines, so there is minimal, if any, impact on the cooling package.
The QSL9 combines very high strength with a compact footprint, for one of the best power-to-weight ratios in its class.
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 1200 lb-ft (1627 N•m) for the QSL9.
