一、新机为何功率不足 一台新上海—50型拖拉机,使用不久便出现了功率不足,排气冒黑烟的现象,经过检查发现,空气滤清器内加了机油。问题就出在这里。目前,新90、95系列柴油机广泛采用纸质滤芯空气滤清器,滤清器是由骨架和微孔滤纸粘合而成的,为增大通气面积,通常微孔滤纸呈折叠状粘在骨架上。使用中,应严防滤芯与油、水、火接触,以免损坏滤芯。有的机手只学过三级油浴式空气滤清器的保养方法,误认为空气滤清器都要加机油,因此在纸质滤芯 First, the lack of power for a new machine A new Shanghai -50-type tractor, the use of shortly after the emergence of lack of power, exhaust black smoke phenomenon, after inspection found that the air filter added oil. The problem lies here. At present, the new 90,95 series of diesel engines widely used paper filter air filter, the filter is formed by the skeleton and porous filter paper adhesion to increase the ventilation area, usually microporous filter paper was folded in the skeleton on. Use, should prevent the filter and oil, water, fire exposure, so as to avoid damage to the filter. Some experts only learned three oil bath air filter maintenance methods, mistakenly believe that the air filter must be plus oil, so the paper filter
