ON THE INFLUENCE OF THE SUPERCHARGING RATIO ON THE FRICTIONAL LOSSES OF A SINGLE-CYLINDER DIESEL ENGINE

Frictional losses of reciprocating internal combustion engines, as part of total losses, play an important role in energy saving problems. The influence of the supercharging ratio on frictional losses, in this paper, is especially analysed. All the experiments have been carried out employing a direct injection single-cylinder AVL diesel engine. The results of this investigation proved that the frictional losses, expressed through the frictional mean effective pressure, linearly increase with the supercharging ratio at given values of the brake load and of speed of rotation. Such an influence is expressed by a relation proposed by the Authors.
