Huanyu Marine & Machinery Co.,Ltd. is the leading manufacturer and supplier of marine engine parts such as diesel engine cylinder liner, piston skirt, cylinder head, exhaust valve casing, piston head, oil burner nozzle, Turbocharger, water jacket and needle valve in China.Founded in 1996, since its inception the company take utmost care of quality at every stage of the manufacturing process. We specialize in developing custom-made parts as per customer specifications. Our immense expertise and experience in the field of marine engine parts and diesel engine cylinder liner, such as B&W, SULZER, MAN etc, has enabled us to deliver the most innovative, reliable and cost effective product range.

    1. Diesel Engine Cylinder Liner
    2. Diesel Engine Cylinder Liner Formed cylinder working space with cylinder cover and piston.
      Cylinder liner of trunk piston diesel withstands side thrust of piston, so it becomes lead of piston reciprocating action.
      Transmit heat of piston assembly and self-heat to cooling water tokeep its proper working temperature.
      Cylinder liner of two stoke diesel engine is equipped with vent; it ishoisted by piston to achieve air distribution.
    1. Cylinder head/cover
    2. Cylinder head/coverCylinder head is used to seal the top of cylinder liner, formed airtightoperating space with piston and cylinder liner.
      Fix cylinder liner tightly to the proper position of the machine, and makepiston operate properly.
      To install various accessories of diesel engine, such as oil burner nozzle,intake and exhaust valve unit, cylinder starting valve, indicator valve, safetyvalve, valve arm, etc.
    1. Piston crown
    2. Piston crownWorking conditions: under bad conditions such as hightemperature, high pressure, high speed and badly lubricating. Piston touch withhigh temperature gas directly, constant temperature can achieve more than2500K, heated greatly with bad heat dissipation, so piston working temperatureis very high, with its top up to 600~700K and temperature is unevenlydistributed; top of piston withstands high gas pressure, especially for workingprocess ...
    1. Piston Skirt
    2. Piston SkirtPiston skirt is the part below piston ring land. Itsfunction is to keep vertical position of piston during reciprocating action,which is leading part of piston. The skirt part slide with high speed incylinder under side thrust action, so it is badly worn. When designing skirtpart, it should have enough bearing area to reduce beta ratio and form oilfilm; assure right cylindrical shape of skirt part and keep minimal gap withcylinder ...
