Summary:

The article presents the results of research on the impact of fuel type on the consumption of selected, components and piston nodes of internal combustion engines. The objects of research were medium-speed piston self-ignition engines, driving generators feeding by residual fuels. Among the tested types of engines, this one powered by residual fuels was subject to intensive wear. These fuels contained significant amounts of sulfur, water and are characterized by a large number of Conradson.Wear investigations were conducted under various natural operating conditions, including often adverse tropical regions. Significant wear of combustion chamber elements was found, such as: cylinder liners, pistons, cylinder heads, timing valves and injection equipment. The consumption states of selected elements were compared to those of the distillation fuel supply.Intensive wear results from the design of the investigated engines, in which the lubrication system for pistons and sleeves and crankshaft bearings is not separated. Wear investigates were carried out mainly with the use of passive observation, geometric and microscopic measurements, image analysis and the use of passive and passive diagnostic experiments. Apart from the intensive consumption of metallic materials, the problem in the tested internal combustion engines was the formation of deposits. The purpose of the research was also to identify types of wear.The new ecological requirements force the use of fuels with a limited sulfur content, exhaust gas treatment or in some regions only the use of distillation fuels. The use of distillation fuels in engines designed to be powered by residual fuels also raises new problems
