Dosing-control units
Bosch uses DCU for a dosing control unit in its Denoxtronic exhaust-treatment systems. Bosch identifies DCU17 as an optional controller for Denoxtronic 5; a separate Bosch technical reference describes DCU15 in a delivery module. These units control dosing-system functions: the controller, supply pump and dosing injector are related components, not necessarily the same part.
