Pneumatic control device for internal combustion engine, has conduit connecting electro valve to pneumatic actuator, pneumatic control branch connected to vacuum circuit by electro valve, and pressure sensor arranged on branch

摘要

The device has a conduit (8) connecting an electro valve (4) to a pneumatic actuator (3), and a pneumatic control branch (18) connected to a vacuum circuit (2) by the electro valve. A pressure sensor (19) is arranged on the branch, and the actuator includes an actuating unit (17). A control unit (16) disposes calibration curve that is predetermined from displacement of the activating unit. The pneumatic control branch is composed of the pneumatic actuator of the electro valve. The pressure sensor is arranged at the conduit. An independent claim is also included for a control method.
