    • PROBLEM TO BE SOLVED: To provide a blow-by gas reducing device for avoiding the production of intake deposits resulting from oil which cannot be removed by an oil separator, and also to provide an internal combustion engine equipped therewith. SOLUTION: In the blow-by gas reducing device, a PCV valve 97 and an oil trapper 98 for collecting oil which cannot be removed by the oil separator 92 are provided on the downstream side of the oil separator 92 which separates and removes oil mist from blow-by gas, and a flow path for the blow-by gas ranging from the oil separator 92 to the oil trapper 98 is located in a cam chamber 3A of the engine E. This suppresses the production of condensed water in the flow path and eliminates the existence of a region where sludge producing conditions (NOx, oil and acid water) are established, and also greatly reduces the amount of oil to be introduced into an intake system and avoids the production of intake deposits.

    • 要解决的问题:提供一种窜气减少装置,用于避免由油分离器不能除去的油产生的进料沉积物的产生,以及提供配备有内燃机的内燃机。 解决方案:在窜气减压装置中,在油分离器92的下游侧设置有用于收集油分离器92不能除去的油的PCV阀97和油捕集器98,其分离和去除 来自窜气的油雾,从油分离器92到油捕集器98的窜气的流路位于发动机E的凸轮室3A内。这抑制了在 流动路径,消除了建立污泥生成条件(NOx,油和酸性水)的区域的存在,并且还大大减少了被引入进气系统中的油的量,并避免了进料沉积物的产生。 版权所有(C)2008,JPO&INPIT
