Abstract

A system and method for sampling fluid from a top land piston crevice of a reciprocating piston engine. Access into the crevice is via a bore through the piston wall. A collector receives sampled fluid from the piston crevice, and has a housing, a valve, and a shuttle. The housing is an elongated hollow shell having a bore through its length, with the bore containing the valve and the shuttle. The valve opens to allow sampled fluid to pass along the bore toward the shuttle, when the valve is in an open position. The shuttle serves two purposes: it moves back and forth within the bore, thereby opening the valve, and also provides passages for storing sampled fluid within the housing.
