Abstract (en)
[origin: WO2014106688A1] The control arrangement and method allow an additional opening of a cam-driven exhaust valve (17) of an internal combustion engine for exhaust gas recirculation. Hydraulic fluid can be introduced into a hydraulic fluid chamber (11) that is arranged between a cam (2) and force transmission means (12, 18) and delimited by a piston (5) that is engaged with the force transmission means (12, 18) at least during the opening and closing movement of the exhaust valve (17). The cam (2) comprises a portion (2c) below the base circle (2a) of the cam (2), and engagement of a cam follower wheel (3) with the portion (2c) below the base circle (2a) is arranged to prevent outflow from the hydraulic fluid chamber (11).
