Abstract: A centrifugal pendulum for damping rotational irregularities of a driveshaft of an internal combustion engine, having a carrier flange element connectable indirectly or directly to the driveshaft, and having multiple pendulum elements displaceable in relation to the carrier flange element, and guided via rollers in pendulum paths. Each pendulum element is displaceable in relation to the carrier flange element in the circumferential direction between a first and a second stop position. At least one friction element having defined thermal expansion properties, which are different in particular from the carrier flange element and/or the pendulum elements, is associated with the carrier flange element, and is designed and arranged in such a way that in a defined temperature range of the centrifugal pendulum, upon a movement of at least one pendulum element corresponding to the friction element in the direction of a stop position.

Abstract: In an air intake system of a multi-cylinder internal combustion engine with exhaust gas recirculation, particularly a Diesel engine, including an intake duct with a throttle valve wherein the intake duct is connected to an intake manifold of the engine and an exhaust gas recirculation conduit is connected to the intake duct downstream of the throttle valve, the throttle valve includes a valve member provided with a turbulence plate which has a diameter smaller than the valve member and extends normal to the valve member, and the valve member has passages and the turbulence member has holes for generating turbulence in the intake duct downstream of the throttle valve.
