摘要： An oil return passage that is open at its upper end to a cam chamber and is open at its lower end to a crank chamber is formed to extend from a cylinder head to a cylinder block. A heat exchanger having a double-pipe structure is housed in the oil return passage. Lubricating oil fed from the cam chamber is passed through an oil-collection outer passage of the heat exchanger, and separated oil fed from a separator case of a PCV system is passed through an oil-collection inner passage of the heat exchanger, so that heat of the lubricating oil is imparted to the separated oil. Thus, water contained in the separated oil is evaporated, and the amount of water flowing into an oil pan can be reduced.

摘要： A casing of an oil separator has an inlet port through which blow-by gas flows into the oil separator, and an outlet port through which the blow-by gas flows out of the oil separator. The casing defines a blow-by gas passage the extends to connect the inlet port to the outlet port. A separation mechanism is located in the blow-by gas passage. The separation mechanism traps oil in blow-by gas, thereby separating the oil from the blow-by gas. A drain port is formed in the casing to drain the separated oil. The outlet port is located in one of opposite side portions of the casing. The drain port is located in the other one of the opposite side portions of the casing. The oil separator is capable of reliably suppressing repeated splash of the separated oil.
