目前,越来越多的国产高速柴油机增装了废气涡轮增压器。由于废气涡轮增压器转速高达40000-70000 r／min,因此对其润滑条件的要求也很高。由于润滑不充分而导致废气涡论增压器损坏的现象在高寒地区时常出现,最常见的就是轴承损坏。废气涡轮增压器轴承损坏的根本原 At present, more and more domestic high-speed diesel engines are equipped with exhaust turbochargers. As the exhaust gas turbocharger speed up to 40000-70000 r / min, so its lubrication requirements are also high. The phenomenon of damage to the exhaust vortex turbocharger due to inadequate lubrication often occurs in alpine regions, the most common of which is bearing damage.
