Liquid Forging · Replace at 60k‑100k km: Exploring Piston Precision Processes, Operating Principles, and Practical Replacement Intervals

This film analyzes the technical and service aspects of the Piston from three dimensions: *Process 1.Liquid forging or precision casting, with T6 heat treatment for grain refinement and zero internal defects. 2.Fully automated CNC machining with skirt profile, ring groove, and pin bore tolerances ≤±0.005mm. *Operating Principle 1.The piston reciprocates inside the Cylinder liner. 2.Four‑stroke cycle (intake‑compression‑power‑exhaust): during the power stroke, combustion gas pressure forces the piston downward, converting linear motion into rotary torque via the connecting rod. 3.Together with piston rings and pin, forms a complete Piston Set that seals the combustion chamber, controls oil consumption, and transmits power. *Replacement Interval 1.Naturally aspirated engines: inspect or replace around 80,000‑100,000 km under normal use. 2.Turbocharged / high‑performance engines: evaluate wear at 60,000‑80,000 km. 3.Early inspection is needed if oil consumption rises noticeably, abnormal engine noise occurs, or power drops. During an overhaul, the Piston Set (including rings) is typically replaced as a complete unit, often along with a new cylinder liner. With precision manufacturing processes, clear explanations of operating principles, and science‑based replacement intervals, we deliver reliable Vehicle parts, Engine Parts, and Auto Parts to the global market.
