1.注意试运转。新的或大修后的发动机必须经过严格的磨合试运转后,才允许投入正式作业。因这些新的配合件从表面上看似乎很光滑,但在显微镜下仔细观察还是凹凸不平的,若不经磨合立即投入作业,这些凹凸不平的表面互相嵌合会产生拉毛,这样会加快轴颈等件磨损,甚至引起烧瓦抱轴。
1. Attention to test run. After the new or overhaul of the engine must undergo a rigorous run-in trial before allowing the formal operation. Because these new mating parts appear superficially superficially smooth, they can be carefully observed under a microscope or bumpy. If they are put into operation immediately after they have not been worn in, these uneven surfaces will be churned together, which will speed up the journal Wear pieces and other pieces, and even cause burning shingles.
