Complete sets of piston rings 4 pcs.
Piston fingers 4 pcs.
Pistons (graphite + phosphated coating) 4 pcs.
Saves fuel, increases life, reduces engine noise.
Complete set for one engine.
The new pistons have a phosphate coating of the piston and an anodized groove for the piston ring.
This reduces the coefficient of friction and increases wear resistance and corrosion resistance and improves oil absorption compared to a conventional piston.
The main indicators from the phosphated surface:
Coefficient of friction is 25-30% less
Surface capacity increases 3-4 times, from 2.5 to 7-10 g / m2
Corrosion resistance Increased more than 10 times
Heat resistance Properties are stable up to 500 ° С
Basic parameters of anodized surface:
Hardness is 3 times higher than the hardness of the piston material
Strength increased 1.5-2 times
On the outside diameter, the pistons are divided into five classes (A, B, C, D, E) through 0.01 mm (measured in a plane perpendicular to the piston pin at a distance of 52.4 mm from the bottom of the piston)
Piston class for external diameter A B C D E
