OREANDA-NEWS. May 13, 2011. Buyers of KAMAZ vehicles submit much fewer claims for replacement of broken engine parts. Thanks to an entry control system, KAMAZ managed to screen a number of suppliers whose components for engines didn’t meet requirements set by the company.

The Research and Development Center of KAMAZ is always developing and improving subassemblies. To date, the company successfully applies the best international practices in production of engine parts. OOO Federal Mogul Naberezhnye Chelny US-Russian Joint Venture has been cooperating with the enterprise in this activity for already a year and a half. The quality of parts of a cylinder-and-piston group for Russian KAMAZ trucks has improved substantially. Thanks to technological innovations and American know-how introduced at the JV, parts of a cylinder-and-piston group of the company have several advantages over their Russian analogs.

Sets of piston rings were particularly improved; they are three times as wear-resistant as old models. New types of rings developed at Federal Mogul are better adapted to the shape of the cylinder. It enabled to significantly reduce oil consumption during engine operation. These rings are adapted to all types of power units produced by OJSC KAMAZ, ranging from Euro-1 and to Euro-5 engines of the new generation developed currently. The quality of casting and machining of cylinder liners was significantly improved. Decreased roughness and oil absorption of the working surface of parts enabled to reduce their wear resistance both during breaking-in, and during their further operation.

Another innovation which greatly improved the performance of KAMAZ engines was the introduction of the Common Rail fuel injection system made by Bosch, Germany. It enabled not only to reduce fuel consumption and exhaust emissions, but also, thanks to a new torsional vibration damper in a high-pressure fuel pump drive, to reduce the noise from a running power unit and enhance its reliability.

The use of new developments in KAMAZ engines increases their operating life up to 1 million kilometers, and therefore enables to satisfy one of the major international requirements currently set by the EU countries for producers of motor vehicles.
