Abstract

In designing railway combustion engines, the key objective is to reduce fuel consumption. The way to achieve this objective is reduction of friction losses in the piston – cylinder node, which is the main in combustion engine. The analysis subjected railway engine DZC6 produce by ANGLO BELGIAN CORPORATION, where on the basis of the parameters was carried out simulations for pistons with revised microgeometry bearing surface.
