cylinder walls and pistons • Carrying away contaminants Figure 7-17. Wet-sump oil system. Reciprocating engines use either a wet-sump or a dry-sump oil system. In a wet-sump system, the oil is located in a sump that ... integral part of the engine. In a dry-sump system, the oil is contained in a separate tank and circulated through the engine by pumps. [Figure 7-17] The main component of a wet-sump system is the oil pump…
