Abstract This article draws attention to the problems of maintaining fuel injection pumps of marine diesel engines in the conditions of use of residual fuels whose quality is steadily deteriorating, and also burned under engine’s reduced load and in situations where the international rules require a temporary change over into distillate fuels. The analysis of tribological processes occurring in hydraulic precision pairs of fuel injection pump such as barrel-plunger was presented and the types of occurring wears were discussed based on author’s own operational experience. There was pointed out the need for additional methods of verification / evaluation of technical condition using of technical diagnostic methods. Introduction by the International Maritime Organization (IMO) and the ratification by the associated countries, the rules relating to the control of emissions in special areas called Emission Control Areas (ECA) through changes in the International Convention for the Prevention of Pollution from ships: MARPOL – Annex VI, not only raised the operating costs or forced to ship owners / managers to comply with the provisions of the Convention, but above all had an impact on the operation of ships. It necessitated the use of fuel oils with low sulfur content called low-sulfur fuels, and in many cases, has ruled out the use of residual fuel to distillate fuels
