- The problem of lubricating oil consumption still seems to be important one at least because of the use of DPFs in exhaust systems of diesels. Even a minor consumption can be a source of particulate matter that blocksfilters. On the other hand formation of oil film parameters that guarantee minimum oil consumption could lead to the increased friction losses. Ali these remarks relate to the nominal temperature ofoperation. Situation can differ at temperature of cold start. Presented paper deals the problem of oil consumption at lower temperatures. The observation concerning friction losses under these conditions are mentioned as well. Parameters influencing the lubricating oil consumption, oil consumption at nominal temperature of engine run, oil consumption at low temperature are presented in the paper. As well course of oil film thickness, layer thickness and friction force for upper compression ring at engine nominal temperature of operation, course of oil film thickness, layer thickness and friction force for upper compression ring at lower engine run temperature, ring face wetting level at nominal temperature of operation, ring face wetting level at lower temperature of operation, lubricating oil consumption and friction losses generated by ring pack of single cylinder are subject of the paper.
