Improved piston running in low-speed diesel engines

Verbesserter Kolbenlauf von langsam laufenden Dieselmotoren

  • 32 Accesses


The piston-running behaviour of large-bore low-speed diesel engines is a complex process influenced by many different parameters. Recent investigations at Wärtsilä have shown that the piston-running behaviour of Sulzer RTA engines could nevertheless be greatly improved by straightforward design solutions. These measures are all combined in the TriboPack design standard which is now incorporated in all new Sulzer RTA engines. This article, based on one of three awarded papers [1] of the latest CIMAC congress, outlines the research results behind TriboPack and explains why it is the remedy for various tribological phenomena encountered in the past in Sulzer RTA engines.
