A cylinder housing for a reciprocating-piston internal combustion engine, in particular of a motor vehicle, includes a first cylinder which is delimited by a first cylinder barrel and a second cylinder which is delimited by a second cylinder barrel. The cylinders differ from one another with respect to their respective inner contour formed by the respective cylinder barrels.

An engine block for an internal combustion engine of a motor vehicle has a cylinder within which a piston can be movably accommodated between a top dead center and a bottom dead center and has a cylinder bore, the internal cylinder diameter of which expands in the direction of the bottom dead center. The internal cylinder diameter expands only below the region in which a piston system change takes place during operation of the internal combustion engine. The internal cylinder diameter tapers from the top dead center to the region.

An electrode and method for the electrochemical machining of a workpiece is disclosed. The electrode is designed as a cathodically polarized tool electrode. It has a geometry that corresponds to the geometry to be removed from the workpiece, at least in a machining range, and perviousnesses in the electrode to allow an electrolyte to flow through and exit at the electrode surface, at least in the area of the machining range. The perviousnesses are formed by a porous design of the electrode and/or by artificially created openings in the electrode or the electrode surface. The porosity distribution and/or the number, arrangement and configuration of the openings is selected such that a uniform electrolyte flow and/or electrolyte exchange at the electrode surface is ensured at least in the machining range of the electrode.

Electrode and method for electrochemically machining a workpiece

A method and an apparatus reduces particles in exhaust gases of an internal combustion engine by passing the exhaust gases through a microwave energy field in a resonator for applying energy and burning the particles. In order to improve the application of energy, the particles are agglomerated beforehand in a high-voltage field of an electrostatic filter.
