ABSTRACT:
A system for controlling turbocharger compressor surge includes a turbocharger compressor fluidly coupled to an engine intake manifold, an exhaust gas recirculation (EGR) valve disposed in-line with an EGR conduit fluidly coupled between the engine intake and exhaust manifolds, means for determining a mass flow parameter, a speed sensor producing a speed signal indicative of turbocharger speed, and a control computer configured to determine a mass flow rate surge value, corresponding to a fresh air mass flow rate above which turbocharger compressor surge is avoided, as a function of the speed signal, and to limit the EGR valve position and VGT position as a function of the mass flow parameter and the mass flow rate surge value to maintain exhaust gas flow through the EGR valve at a flow rate below which turbocharger compressor surge is avoided.
