Qin Piston Ring Excellence ^Popular

QIN piston rings can be found in the main engines of the planet’s largest container vessels and fastest ferries as well as the auxiliary engines of the worldwide fleet. QIN piston rings are designed to operate with all fuels under the most stringent environmental conditions.
Fire bands, or anti-polishing rings, are rings inserted in the upper end of the cylinder liner in order to minimise carbon deposits building up on the higher area of the piston surface above the top compression ring.
