69. The diesel generator engines onboard your mollusc dredger use a lubricating oil filtration scheme as shown in the illustration. What type of filtration system is illustrated

The system is full-flow filtration because all oil delivered to the engine bearings passes through the filter housing. An internal bypass valve protects against element clogging, but does not alter the system's classification. This contrasts with bypass systems, which filter only a portion of the oil, and do not route it to the bearings.
