An internal combustion engine has a separate exhaust passage for each one of banks. An exhaust purifying catalyst is provided in each exhaust passage. The mass flow rates G, Gof exhaust gas that flow through the exhaust passages are individually estimated. The flow rate of exhaust gas is individually adjusted per each bank by controlling the operation of each one of exhaust gas recirculation valves such that the difference between the estimated mass flow rates G, Gis decreased.

Exhaust purifying apparatus for internal combustion engine

A motor includes a rotatable cylindrical rotor housed in a stator and has a female threaded nut formed inside the rotor. The motor has a male threaded screw shaft engaging with the nut. The rotation of the rotor is transformed to linear movement of the screw shaft by restricting the rotation of the screw shaft. A plurality of engaging sections project from the screw shaft. A contact section is provided with the rotor to contact with the engaging sections. The contact section contacts the engaging sections in accordance with the rotation of the rotor to restrict the rotation of the rotor and to prevent the screw shaft from releasing from the rotor.
