Сэлбэг бүр хэрхэн эвдэрдэг, солихоос өмнө юуг хэмжих, хямд хувилбар яагаад эхэлж эвдэрдэг. Брошур биш, вандан сандал дээр харж байгаагаар бичсэн.
A piston fails in three ways: the ring grooves wear oversize, the crown cracks from heat, or the skirt scuffs from poor lubrication. Which type you buy decides how long it lasts.
Унших →LinerA liner does not just guide the piston. Its surface holds the oil film and its outer wall sits in coolant. Both sides fail in different ways.
Унших →RingRings do four jobs: seal combustion gas, support the piston, spread oil, and scrape it back. A ring that only seals but does not scrape gives you blue smoke and oil consumption.
Унших →ValveThe intake valve is cooled by incoming air. The exhaust valve is heated by it. That single difference explains the materials, the coatings, and the failure modes.
Унших →BearingA bearing is not a plain bush. It is a steel back, a bonding layer, and a running layer chosen for load. Measuring it wrong is more common than wearing it out.
Унших →CrankshaftA crank is judged on journal size, taper, roundness and cracks — not on how it looks. The material matters because it sets how much you can grind before it is scrap.
Унших →RodRods fail at the bolts and at the small end far more often than in the middle. The bolt is the part people reuse, and that is usually the mistake.
Унших →GasketA gasket is a controlled leak path that has to seal three different things at once: combustion pressure, coolant, and oil. The material is chosen for which of those dominates.
