BMW Valvetronic Eccentric Shaft - OE Supplier 11377589883

Valvetronic puts an arm between the lifter and the camshaft, which regulates how much of the camshaft’s lift is applied to the valve. The arms, called Intermediate Levers, ride on the Eccentric Shaft and are actuated by an electronic motor. The engine computer controls the motor and drives a gear that rotates the Eccentric Shaft, determining how much cam lift is used at any time. Although BMW’s engines have throttle bodies as fail-safes, the Valvetronic system effectively regulates the air entering each cylinder
