Ceramic Coating Cylinder

  • Brief Description and Advantage
    Ceramic Coating Cylinder is a high-tech product, which applies special compound-electroplating process to disperse SiC ceramic particles uniformly distributing on the cylinder wall. SYM is the first company in Taiwan to make mass production of motorcycle engine by utilizing SiC ceramic coating technique.
  • The Ceramic Sic material can overcome the weakness of general ceramic materials, and in the meantime it possesses excellent properties of high hardness (wear resistance), heat resistance and etc., which can be the best candidate matchin g the requirements of the engine cylinder. However, general conventional electroplating techniques cannot disperse SiC ce ramic particles on the cylinder wall due to the insulation and high weight. As a result, SYM have developed the special comp ound-electroplating process to disperse Ni particles and SiC particles on the cylinder wall together, which forms a particular cylinder with the compound-electropl ating layer (Ni/SiC), and brings the quality to excellence.
  • Currently the quality control of mass production has already achieved to maintain the defective rate below 0.3%, so the ceramic coating cylinder with high quality and appropriate price can therefore be produced.
  • Item Hardness Wear (Maximum Power Test) Temperature of Cylinder Wall
  • Traditional Cast Iron SleeveHv 200~300 around 49.5μm 236℃
  • Cylinder SiC Particles > Hv2000 < 2μm 221℃

S.T.C.S.( Swirl Tumble Control System)

S.T.C.S movie

 

SYM all new design, combines the tumble and swirl characteristic of air motion into one single engine, called swirl- tumble control system—S.T.C.S.

 

 

1.Depending on speed
or loading, the built-in
ECU chip signals for
variable air flow patterns
and results in enhanced performance.

2.When high speed or full load, the swirl valve is opened, the mixture (air and fuel) flows through TWO inlet port into the cylinder.   3.During low speed or light load condition, the swirl valve of the system closed one of the two inlet port.   4.Depending on speed or loading, the built-in ECU chip signals for variable air flow patterns and results in enhanced performance.
