Description
Product Overview
The MAN B&W 3157167-5 MCU Module is a marine engine control component associated with MAN B&W engine automation and Alpha Lubricator systems. MCU stands for Master Control Unit, and supplier listings identify this part number as a control module used in compatible marine engine installations.
The module supports control and coordination functions within the relevant engine control architecture. Its exact operational role depends on the engine model, lubricator configuration, hardware revision, and associated control equipment. Related listings also identify references such as 1142352-0 and 14.0230.0, which should be checked against the physical module before ordering.
This component is intended for marine engine maintenance, control-system servicing, and spare-parts replacement. Because engine-control modules can be configuration-specific, verify the complete part number, revision, and original equipment requirements before installation.
