自从柴油机烧重油以来,就提出了涡轮增压器的涡轮能否在运行中清洗的问题。燃料中的杂质在喷嘴和涡轮叶片上形成积碳,因而使流道截面积减小,并改变其几何形状,其后果是使增压压力下降,排气温度升高和增压器效 Since the diesel engine burns heavy oil, it has been asked whether the turbo turbocharger can be cleaned during operation. Impurities in the fuel form soot on the nozzle and turbine blades, reducing the cross-sectional area of ​​the flow passage and changing its geometry, with the consequence of a decrease in boost pressure, an increase in exhaust gas temperature, and a supercharger effect
