BLOW-BY GAS TREATING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a blow-by gas treating system capable of properly treating blow-by gas in an engine of using fuel as lubricating oil. SOLUTION: This blow-by pass treating system 1 has a lubricating oil separator 2 separating the lubricating oil from the inside of the blow-by gas, and a fuel supply device 3 supplying the lubricating oil separated by the lubricating oil separator 2 to an injection system as the fuel. The lubricating oil separator 2 has a lubricating oil separating chamber 5 separating the lubricating oil by introducing the blow-by gas, a cooling medium passage 6 for making cooling water flow to the periphery of the lubricating oil separating chamber 5, and a lubricating oil storage part 7 storing the lubricating oil cooled and separated from the blow-by gas. A supply pump 9 is connected to the lubricating oil storage part 7. The supply pump 9 supplies the fuel in the lubricating oil storage part 7 and a fuel tank 10 to a common rail 12 under high pressure. COPYRIGHT: (C)2008,JPO&INPIT
