Abstract: An engine assembly for a vehicle includes an internal combustion engine and an exhaust system. The exhaust system includes a catalytic converter, a main muffler, a hydrocarbon trap, a pre-muffler disposed upstream from the main muffler and the hydrocarbon trap, and an exhaust path valve. The exhaust path valve is movable between first and second exhaust path positions. The exhaust path valve obstructs a second exhaust path in the first exhaust path position such that exhaust gas flows from an exhaust port of an engine cylinder to the catalytic converter to the main muffler and to the atmosphere. The exhaust path valve obstructs a first exhaust path in the second exhaust path position such that exhaust gas flows from the exhaust port of the engine cylinder to the catalytic converter to the hydrocarbon trap and to the atmosphere.

Abstract: A method for checking a capacity of at least one supply line for an electrically operated assembly that is coupled electrically via the at least one supply line to an electrical system of an at least partially automated mobile platform. The method includes: ensuring a non-critical operating state of the mobile platform; determining an off-load terminal voltage at an input connection of the assembly, with zero-current supply line; applying a defined current to the supply line of the electrically operated assembly; determining an on-load terminal voltage at the input connection of the assembly, in doing so, the defined voltage being applied to the supply line of the electrically operated assembly; determining a differential voltage between the off-load terminal voltage and the on-load terminal voltage; comparing the differential voltage to a differential-voltage limit value to determine whether the capacity of the electric supply line is sufficient to operate the assembly.

Abstract: A method for producing round stock (10) which is provided with at least one inscription and/or marking (16), at least the surface (12) of the round stock (10) consisting of a metallic material, in particular of chromium or steel, for example of hardened steel, chromium-plated steel or stainless steel.

Abstract: A sensor (S) is provided for determining the stroke of the piston rod (6) of a fluid cylinder, particularly a hydraulic or pneumatic cylinder. The sensor includes a lighting unit for illuminating a code applied on the surface of the piston rod and differing from said surface by color, a first camera unit with a first lens system for recording a first image of the illuminated code in a first scanning window, an evaluation unit for evaluating output signals of the first camera unit, and an interface for issuing the evaluated output signals as information regarding the position of the piston rod. Additionally, a second redundant camera unit is provided with a second lens system, which serves for recording a second image of the illuminated code in a second scanning window.
