Changes Of Toxic Compouns Of Exhaustes During The Running-In Of Engine

Reliability and durability are the most important features of the combustion engines. The significant influence on these features has construction, production technology, and proper selection of materials. Regardless of precise producing the cooperative elements of the engine should undergo the running-in process. This process has great influence on durability of elements and normal time of exploitation. If it is properly selected and conducted, it will extend the time of future engine operation by decreasing initial value of wear of its friction pairs and giving proper values to the outer layers. During the running-in process, beside giving proper shape to the outer layers of individual elements of engine, parameters of the toxic compounds emission changes. The paper presents results of researches, which were aimed at describing the values of toxic compounds emission changes during the running-in process of engine.
