Patent ·
OSTI ID:6487767

This patent describes a method of turbocharger control in a vehicle having an engine and a turbocharger for increasing the density of at least the air entering a cylinder of the engine. The turbocharger has at least a compressor and a turbine coupled by a shaft and a nozzle to increase the angular momentum of the flow of gas to the turbine. The nozzle has a housing and movable vanes to vary the angle and velocity that the exhaust gas hits the wheel of the turbine, and actuator for moving the vanes, a can separated by a diaphragm and having an A side and B side for actuating the actuator, solenoid-actuated valves for controlling the pressure in the A and B sides of the can, an electronic control unit (ECU) having memory for storing data and predetermined values and for actuating and de-actuating the solenoid-actuated valves, a plurality of inputs to the ECU for providing input data indicative of engine temperature, engine speed, vehicle speed, intake manifold pressure, throttle angle, engine knock and charge air temperature.
