Methods of calculation, diagnostics and regulation of a system of gas’s recirculation of supercharging engine’s unit

Abstract

This article describes the problems of selecting structural and adjustment parameters of a system of automated control by energy of an engine’s exhaust gases flowing to the blades of a turbine wheel. Controlling the air pressure’s magnitude at the outlet of the compressor and limiting the maximum speed of the turbocompressor’s shaft is carried out by the exhausted gases’ recirculation. There is presented a method of calculating system of the gas recirculation in the turbine of supercharging engine’s unit, considering balance of forces influencing the membrane, spring, rod and screen. There are considered the ways of diagnosing and regulation of a system of gas recirculation past turbine.
