Ceramic Engine Parts Mercedes Benz Piston 128mm , OEM 4220300617 - Product

Other Specification : Ceramic Engine Parts Mercedes Benz Piston 128mm For OEM 4220300617 MERCEDES BENZ PISTON OM422 LA FOR DIESEL ENGINE OEM 4220300617 A Piston Is A Component Of Reciprocating Engines, Reciprocating Pumps, Gas Compressors And Pneumatic Cylinders, Among Other Similar Mechanisms. It Is The Moving Component That Is Contained By A Cylinder And Is Made Gas-tight By Piston Rings. In An Engine, Its Purpose Is To Transfer Force From Expanding Gas In The Cylinder To The Crankshaft Via A Piston Rod And/or Connecting Rod. In A Pump, The Function Is Reversed And Force Is Transferred From The Crankshaft To The Piston For The Purpose Of Compressing Or Ejecting The Fluid In The Cylinder. In Some Engines, The Piston Also Acts As A Valve By Covering And Uncovering Ports In The Cylinder Wall. Piston Technology Tin Coating Tin Is Coated By Electro Analysis Or Heat Dipping At Thicknessbetween 0.001 And 0.003mm. Tin Is Characterized As Soft And Oil-friendly Which Improves Running-in Efficiency Of Piston And Liner. This Coating Is Most Commonly Used. Graphite Sprayed At Piston Skirt/Graphite Printing Graphite Is Characterized As Good Lubricating, Which Helps Lubricant Adhering To Coating Surface. The Coating Will Reduce Friction And Scratching. The Thickness Is Between 0.01and 0.02 Mm. Piston Roof Anodizing The Piston Roof Is Anodized By Electro Bath, Forming Thin Layer Of Al2O3 , This Treatment Will Improve Heat Resistance (above 500), Heat Conductivity And Anti-corrosion, It Helps Prevent Piston Roof Burn-up. The Thickness Is Normally 0.02 To 0.05mm. If The Thickness Increases By 0.01mm, The Heat Conductivity Will Decrease By 25%, The Roof Temperature When Running Will Belowerfrom 30 To 50. Anodizing Technology And Processing Is Normally Complicated. Piston Roof MoS2 Spraying The Function Is Close To Roof Anodizi
