Compréhension des mécanismes de formation de dépôts en fond de première gorge de piston de moteurs Diesel

Moussa Diaby
Abstract : The fast degradation of engine oils and the increased formation of deposits in diesel engines are consequences of the use of Exhaust Gas Recirculation (EGR) process associated with increased temperature and pressure in Diesel engines combustion chambers. This thesis was aimed at understanding the formation processes of these deposits in the first piston ring grooves. In this purpose, deposits generated during endurance tests on engine bench, have been analysed. The analyses showed that the deposits mainly resulted from the degradation of lubricants into
