About Relationship Between the Oil Consumption and the Toxic Compounds Emission from IC-Engines

The oil consumption can be considered as a source of the toxic compounds emission in internal combustion engines, The paper presents a theoretical and experimental analysis of the problem. Experimental investigation has been carried out according the European ECE R15 and ECE R49 standard tests for engines (Otto and Diesel types) of regular and doubled oil consumption. A significant increase in emission of hydrocarbons has been found for the increased oil consumption. Characteristics of the polycyclic aromatic hydrocarbons (PAH) group as well as an individual method of the PAH compounds examination have been discussed in the paper (gas freezing method and chromatography have been applied).
