Abstract: A rotating mass component with high balancing quality is provided. The balancing is performed in a substantially automated manner and without chip formation. A method for balancing a rotating mass component, such as a rotor is achieved by deposition welding of welding points on the mass component. The mass symmetry respective to the rotation axis is improved. The deposition welding takes place through cold metal transfer welding, in particular of a plurality of individual mass points.

Abstract: An internal combustion engine with a system for secondary air charging has a combustion unit, an intake air conduit connected to the combustion unit, and an exhaust gas conduit connected to the combustion unit. A throttle is arranged in the intake air conduit. A turbo-engine is connected to the intake air conduit by a supply conduit upstream of the throttle and by a discharge conduit downstream of the throttle. A compressor is provided wherein the turbo-engine is connected operatively to the compressor and wherein the compressor is connected by a connecting line to the exhaust gas conduit. A valve is arranged in the discharge conduit. A vacuum cell actuates the valve. An electro-pneumatic converter is operatively connected to the vacuum cell. The vacuum cell, when reaching a defined differential pressure, opens the valve suddenly so that a vacuum pulse is generated that acts on the turbo-engine.
