煤矿的开采离不开柴油机提供动力,柴油机废气的处理成为井下安全作业的首要问题,以某型无轨胶轮车的防爆柴油发动机为例,详细介绍了防爆柴油发动机废气处理系统的设计、主要冷却部件的作用、废气冷却的方法。对煤矿的安全生产有重要的意义。 The mining of the coal mine can not do without the diesel engine to provide the driving force. The treatment of the diesel exhaust gas becomes the primary problem in underground safe operation. Taking the explosion-proof diesel engine of a type of trackless rubber tire truck as an example, the design of the exhaust gas treatment system of explosion- The role of components, exhaust cooling method. The safety of coal mines have important significance.
