The Institute of Combustion Engines and Transport, in cooperation with the BOSMAL Automotive Research and Development Centre, is working on an analysis of oil consumption in the context of toxic compound emissions. Trends in internal combustion engine design over the past years have been constrained by legal regulations concerning both toxic compounds and CO2 emissions. As a result, internal combustion engine manufacturers have developed a number of improvements not only to enhance combustion but also to reduce oil consumption. The level of oil consumption is, in fact, treated as a criterion for assessing the advancement of an engine. It also ensures the correctness of the engine’s production; furthermore, it indicates that the engine’s operation meets the standards.

Abstract
The Institute of Combustion Engines and Transport in collaboration with BOSMAL Automotive Research and Development Centre has been working on oil consumption in the aspect of toxic compound emissions.Over the past years, the tendencies in engine design have been constrained by legal regulations concerning both toxic compound and CO emissions. As a result, combustion engine manufacturers have developed numerous advancements not only to improve combustion, but also to diminish oil consumption. The level of oil consumption, in fact, is regarded as a criterion for evaluating the engine advancement. It also assures about the scrutiny the engine was produced with; moreover, it indicates whether engine operation is in the norm and the degree to which engine parts have worn off.
The paper comprises a description of both the conventional and laser treatment of the cylinder block. In addition, it presents the results of the research carried out in order to define the influence of the cylinder clock treatment on the oil consumption as well as on the toxic compound emissions.
