Configuration of CUMMINS QSL8.9 Construction Diesel Engine
| Standard Configuration | Optional Configuration |
|
|

The CUMMINS QSL8.9 series diesel engines exhibit configuration differences between construction applications (QSL8.9-C) and generator applications (QSL8.9-G), primarily reflected in the configuration of the cooling fan and water radiator.
In the QSL8.9-C series, these configurations are typically offered as optional configurations to accommodate varying installation space and cooling requirements of different construction machinery. In contrast, the QSL8.9-G series features the cooling fan and water radiator as standard configurations to ensure efficient heat dissipation even under high-temperature environments or heavy-load conditions.
