  • Detail

Piston graphite lubricated antifriction coating ink ITO ink coating Chemical Technology Research Institute recently launched a piston graphite lubricated antifriction coating ink suitable for silk printing to meet the requirements of various piston customers for increasing power and fuel efficiency, extending piston life and protecting the engine. The design of internal combustion engine is continuously improved and debugged. After the redesign of internal combustion engines, the piston is often the most affected component. The friction of the piston will not only affect the final performance of the engine according to incomplete statistics, but also may cause damage to the engine. Ito technical research engineers have successfully developed a piston graphite solid lubrication antifriction coating ink suitable for silk printing process according to the requirements of piston working environment

in order to improve the performance of the piston, cope with the increased friction and improve the engine performance, compared with the piston in the past, today's piston has lighter weight, smaller thermal expansion and better thermal conductivity. In addition, the design of the piston also has small changes. For example, the piston skirt is shorter, and the surface area perpendicular to the pin boring is reduced, so the friction of the piston is also reduced. In operation, these surfaces of the piston bear the pressure from the pin guide and torsion, so the strength of friction is the greatest. Although these changes are significant, with the application of complex cold start and injection systems in the engine, the performance improvement brought by these changes has been greatly weakened. These improvements of the engine bring more fuel into the cylinder, which significantly reduces the viscosity of the lubricating oil film in the piston area, and on the contrary weakens the load capacity of the engine. Although the lubrication technology is constantly improving, every improvement of the engine is also weakening its effect, thus continuously increasing the friction of the piston and the wear of the engine

these high-strength friction will cause serious damage to the engine in a short time, which can be easily found by checking the piston. Unfortunately, the degradation rate of lubricating oil is very fast, and the piston has been damaged before the mechanical personnel or vehicle owners realize it. The following is the result of poor piston lubrication in some current engines

from the positive pole to the electric cell to the whole vehicle system to the echelon utilization and then to the recycling of raw materials.
