Sažetak

Diesel engines are widely used despite their relatively high environmental impact. This fact requires ensuring high quality engine components, including the piston. The article presents a problem related to the occurrence of incompatibility of material structure in the combustion chamber of pistons of one of the Podkarpackie (Poland) piston factories for engines used in passenger cars. The aim of the article is to determine the diagnostic method - optimal from the point of view of quality and economy, convenient for use with large series, 100% control of the combustion chamber of pistons on the production line. Eddy current method was chosen as a solution for automatic inspection of material incompatibilities in the combustion chamber. As a complement to the selected method, a penetration method was proposed for products initially classified as non-compliant. The research was carried out in order to outline the concept of functioning of the proposed system.
