摘要: An internal combustion engine includes a cylinder head, a poppet valve having a seat within the cylinder head, a cam shaft on which is mounted an eccentrically shaped cam, and a rocker arm assembly comprising a rocker arm, a cam follower, and an electromagnetically actuated lash adjuster. The lash adjuster provides a continuously variable length fulcrum for the rocker arm. The actuator may be a piezoelectric stepper motor. The lash adjuster may be operative to vary a rate of internal exhaust gas recirculation and without requiring crank angle data.
