    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.
    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 ...
    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 ...
    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.
    2. Oil Burner NozzlePerformance of oil burner nozzle is extremely important for engine power, fuel consumption and waste gas emission. While parts processing tolerance smallerthan 2/1000 mm is akey element to guarantee nozzle performance, which can meet the tolerance setby engine maker. It's this unique technology and excellent processing which canensure complete satisfactory of customers and properly operating ...
    2. Exhaust Valve CasingDual function, to reduce negative pressure, corrosion-resistant material,brightly colored appearance, good visibility, strong shock resistance, high durability and easy to install.
      Usage: used in pipeline system, to prevent water impact.
      Installed in relatively high point, to expel air of pipeline system whenstart up system, while, to introduce air to prevent vacuum when close system.
    2. Stainless Steel Needle ValveSocket meter valve has many advantages, such as easy to fix and remove,fastening connection, fire-proof, explosion resistant, high-pressure resistant,high sealed ability, etc, it's an advanced valve for connection in electric station, oil refining, chemical plant installations and meter measurement pipeline system.
    2. Water JacketThe water passages in the cylinder block andcylinder head form the engine water jacket. In the cylinder block, the waterjacket completely surrounds all cylinders along their full length. Within thejacket, narrow passages are provided between the cylinders for coolantcirculation around them. In addition, water passages are provided aroundthe valve seats and other hot parts of the cylinder block.
    2. Complete Turn-Key EnginesWe can offer complete turn-keyengine packages for nearly every inboard and sterndriveapplication. From a 3.0L,4-cylinder engine rated at 140hp, to an 8-cylinder, 8.1L engine package rated up to 450hp.
    2. Remanufactured Marine EnginesWeare one of the largest online remanufactured replacement marine engine andmotor supplier in China.For more information, please contact us directly.
