Title: Turbocharger control system

Abstract

A turbocharger control system is described for an engine having a turbocharger with a variable output compressor driven by a variable input turbine, the compressor boosting the pressure of an input manifold of the engine and the turbine being run from the exhaust gases of the engine. The control system consists of: a computing circuit including input circuit means for receiving input signals representative of operational parameters of the engine, programmable memory means for storing predetermined tabular data and sequential and computational instructions, processor means responsive to the memory means for receiving the input signals and generating output signals as a function of the input signals, tabular data, and instructions, and output circuit means for outputing the plurality of output signals, sensor means connected to the engine and the computing circuit for sensing the pressure in the manifold, the temperature of the exhaust gases, the speed of the engine, and position of the throttle, compressor and turbine actuators of the engine and generating signals representative thereof; and actuator means connected to the output circuit means for controlling the position of the actuators in response to predetermined ones of the output signals, respectively; the computing circuit, sensor means, and actuator meansmore » defining a turbine control loop for regulating the input of the exhaust gasses to the turbine as a function of the error difference between an optimum manifold pressure of the engine and the actual manifold pressure of the engine; and a compressor control loop for regulating the output of air flow from the compressor as a function of the speed and acceleration of the engine.« less
