    摘要： A supercharged engine has a charge air intake and an engine exhaust outlet, a positive displacement supercharger connected to the air intake, a charge air and bypass control valve comprising a rotary body throttle valve including a rotary valve body, a primary air passage and a separate bypass air passage each extending through the rotary body. The primary air passage is fully open in a first rotary position of the rotary body wherein the bypass air passage is closed, and the bypass air passage is fully open in a second rotary position wherein the primary air passage is closed. Airflow through the passages varies in an inverse manner as the rotary body is rotated between the first and second positions, whereby airflow through the control valve is controlled with a single actuator movable through the full range of positions and airflow through the primary and bypass passages is inversely varied.

    摘要： A boost purge ejector tee arrangement is integrated into a turbocompressor associated with an engine and includes first and second passages, an inlet port and a nozzle. The first passage is formed into a housing of the turbocompressor and includes an outlet in communication with a turbocompressor inlet. The second passage is formed into the housing and includes a boost air inlet in communication with an internal outlet area of the turbocompressor and intersecting the first passage. The inlet port is associated with the housing and intersects the first passage. The nozzle is positioned in the first passage such that an outlet of the nozzle is proximate the intersection of the inlet port and first passage. During a boost mode of operation, the second passage is adapted to receive boost air flow, which flows through the nozzle thereby creating a vacuum and drawing purge through the inlet port.

    摘要： Techniques for learning endstop position(s) of an actuator for a wastegate valve include detecting a learn condition and, in response to detecting the learn condition, performing a learn procedure for the actuator endstop position(s). The learn procedure includes commanding the actuator to a desired position past the endstop position corresponding to a fully-closed wastegate valve while rate-limiting a velocity of the actuator. When the difference reaches its maximum allowed value and the velocity falls below a fraction of its rate limit, the endstop position is learned. When the wastegate valve is requested open, the actuator is then controlled using the learned endstop position. Reference stiffness for a fully-closed wastegate valve could be obtained, and subsequent stiffness checks could then be periodically performed and, if less than the reference stiffness, a duty cycle of the actuator could be increased during open-loop control.
