摘要
根据内燃机油中的烟炱在高温下与氧气结合而引起失重的原理,利用热重仪来测定内燃机油中烟炱含量,并用此法对行车试验油进行了监测。此法可测定新油及旧油中的烟炱含量,准确性、重复性较好。
According to the principle of weight loss of oil caused by the combination of soot and oxygen under high temperature, the soot content in engine oil can be determined by Thermogravimetric Analyzer. The soot content in the field test oils is measured with the fore mentioned method, which shows good accuracy and repeatability on both new and used oils.
