PROBLEMS CAUSED BY BURNING HEAVY FUELS IN DIESEL ENGINES

The use of residual oils of increasingly poor quality as the fuel for medium-speed diesel engines causes a higher rate of fuel-induced wear in the operation of the engine. Catalyst residues from the cat cracker, the cat fines, and a high sulfur content are mainly responsible for this wear. Fuel-induced wear on liners, piston rings and first piston ring grooves was examined on a MAN VIV23/23 test engine by means of the Radio Nuclide Wear Measurement Technique. A calculation procedure for determining the risk to engine components from low-temperature corrosion was also developed. Results of measurements and calculations are summarized. Countermeasures against abrasive and corrosive wear are also discussed.
