Abstract
Seeking for technologies to meet uprising environmental legislation restrictions all over the world, the use of EGR valves [1] in Heavy Duty Diesel engines seems to be irreversible and so frightening. Despite its notable contribution to Nitrogen Oxides emission reduction, its catastrophic effects on accelerated corrosive wear in liners and piston rings are very well known by the industry. For EGR valves with condensation technology this undesirable effect is substantiated with fuel sulphur content and acids produced by combustion, a characteristic still present in fuels commercialized in Brazil.
This report presents the performance of a bench engine test procedure for heavy duty Diesel that provokes accelerated polish of liners and piston rings by corrosive and abrasive wear in a short period of running test when compared with standard industry procedures for wear and durability evaluation. This methodology allows a simultaneous comparison of performance of different material, under exact same test conditions, reducing running time, test infrastructure and global test costs.
