2. Intake System
2-8. Charge Air Cooler Installation Requirements
The Kubota 03-CRS DOC engines require a charge air cooler. To prevent decreases of engine output performance and to
maintain emission compliance, the charge air cooler must meet the following criteria. The charge air cooler pressure drop and
temperature drop
MUST
be checked during the application review.
1. Maximum allowable pressure drop from turbo charger outlet to intake manifold inlet = <10 kPa
2. Maximum allowable temperature at intake manifold inlet = < A 25° C
Note: Measure charge air cooler pressure drop and intake manifold temperature at rated speed, full load.
