1 问题的提出 增压器是柴油机的重要部件之一。它利用气缸燃烧产生的废气,推动增压器的涡轮旋转,涡轮同轴带动压气机旋转。目前,DF4型机车上基本都是采用VTC和ZN系列增压器。由于该增压器采用的是内支承式滑动轴承,所以对机油的条件要求比较高,工作中既不能缺油,更不能
1 Problem Proposed Turbocharger is an important part of the diesel engine. It uses the exhaust gas produced by the combustion of the cylinder to promote turbocharger turbine rotation, turbine coaxial drive compressor rotation. At present, DF4 locomotives are basically using VTC and ZN series supercharger. As the turbocharger is used within the bearing-type plain bearings, so the requirements of the oil conditions are relatively high, neither the lack of work in the oil, not to mention
