Description: 汽车噪音大小是否与机油粘度有关？

机油与国六排放没有关系，是现在发动机活塞环漏气量大，高温高压气化两道气环中间刮下的缸壁机油，排入曲轴箱，随曲轴箱通风进入进气道吸入气缸，机油油气进缸只有少部分燃烧，附着在活塞顶燃烧室造成积碳，粘稠颗粒物比较多，吸附在颗粒物过滤器管壁上，造成堵塞。
2.4升发动机万公里机油消耗0.25升，都会产生大量积碳，我低漏气不降缸压活塞环应用后，机油消耗极低，不在积碳。国六不用安装颗粒物过滤器器照样达到排放要求。国六即便加普通40机油，也不会造成颗粒物过滤器堵塞。
国四排放安装低漏气不降缸压活塞环后的年检，这够国几排放？

粘度大 噪音也大 沉闷感 ，粘度小 噪音也大 很嘈杂的声音。
粘度合适 噪音最小 。
