Abstract:
A turbocharger assembly for use in conjunction with an engine, said turbocharger assembly comprising:a controller for generating a signal;a turbocharger housing defining an exhaust turbine outlet passage for permitting a flow of exhaust gases from said turbocharger housing, said turbocharger housing further including a backpressure valve actuator assembly having an actuator element operably responsive to said signal, said turbocharger housing further includes an actuator position sensor connected to said controller by a position sensor, said actuator position sensor generating a signal corresponding to the position of said actuator element and transmitting said position signal to said controller; and, a backpressure valve assembly disposed in said exhaust turbine outlet passage, said backpressure valve assembly including a selectively moveable backpressure valve element for selectively restricting the flow of exhaust gases in said exhaust turbine outlet passage to increase the relative backpressure of exhaust gases in said turbocharger housing, said backpressure valve element linked to said actuator assembly for operation in response thereto.
