The paper presents test bench results concerning to oil consumption and blowby of current truck diesel engines. The influence of design factors is demonstrated and the understanding of correlations between oil-consumption and blowby related to design modifications is explained. With the results gained it is pointed out, that significant reductions in oil consumption figures are achieveable by adaptation of pistons and pistonrings to individual engine requirements. Increases in oilconsumption caused by deterioration of components, as for instance cylinder-liner geometrie, related to insufficient crankcase-rigidity, are described. All measures stated are in serial application of current truck diesel engines.
