为了发展地下矿山柴油驱动的采掘设备,1975年一机部召开了内燃机废气净化座谈会,商定了柴油机废气排放的低污染指标[6105Q 柴油机低污染指标为:CO<7.5(克/马力小时);NO_x<6(克/马力小时);HC<1(克/马力小时)],并安排了有关研制任务。现在,由厦门工程机械厂和长沙矿山研
In order to develop diesel-powered mining equipment for underground mines, a workshop was held in 1975 to discuss the internal combustion engine exhaust gas purification seminar and to agree on the low-emission indicators of diesel engine exhaust emissions [6105Q Low-pollution indicator for diesel engines: CO <7.5 (g / hh) NO_x <6 (g / hh); HC <1 (g / hh)] and arranged for development tasks. Now, from Xiamen Engineering Machinery Factory and Changsha mine research
