<p>An electrically responsive turbocharger system (10) for an internal combustion engine in which an actuator (56) operates a wastegate valve (52) normally in dependence upon a spring (68) acting against the exhaust gas pressure. A control system (62) overrides these two opposing forces by locking the actuator (56) in response to an electrical signal corresponding to the compressor discharge pressure. </p> |
