Abstract
The article contains an analysis of a turbocharger model in witch gas bearings were applied. It also gives the measurement results of oil consumption by a turbocharger equipped with a normally used bearing system of a turbocharger. A mathematical model for calculation caring capacity of gas bearings in application to turbocharger was presented in this paper. The article gives also the measurement method of oil consumption by the turbocharger in variants ranges of engine work. Application of such bearings aims at: - elimination of oil penetration from turbocharger intata spaces in the compressor body and turbine. Elimination of these leaks caused a decrease in toxic component concentration in exhaust gases. A significant decrease in the amount of hydrocarbon and a considerable reduction of solid particles is note worth. This problem is specially significant as concerns protection of the natural environment harmed by the ever increasing number of vehicles driven by internal combustion engines with turbocharger. - Application of gas bearings permitted to diminish the moment of friction in the bearing shell of the turbocharger shaft, this has a positive influence on the reaction time of the torbocompressor system. Application of a new type of bearing reduces also the masses of the compressor and this has a positive effect on shortening of the reaction time of the turbocharger. - Reduction of friction in the bearings shells permits to increase the rotational speed of the turbocharger and rotor - Bearings of the new structures should contribute to smaller dimensions of the turbocharger and this will make its housing at the engine easies.
