Abstract: A decorative cover for a back-illuminated interior trim panel for a vehicle, said cover being a sturdy shell-structure including a transparent plate, forming the back side of the shell-structure, and a decorative component top layer including a trim material layer, which forms the outer surface of the decorative cover, wherein the trim material layer is formed from a trim material which is one from a group of materials consisting of a wood veneer, a metallic layer, a paper, a textile and a fabric, and wherein the laminate is configured to have a predetermined degree of translucency.

Abstract: An internal combustion engine for driving a working assembly with a clutch, including a combustion chamber into which a mixture of fuel and air is supplied, a spark plug to ignite the mixture, ignition of the mixture driving a piston operably coupled to a crank portion of the engine, a fuel supply system including a fuel valve and a throttle valve, a throttle position sensor configured to determine a position of the throttle valve, a speed sensor configured to determine engine speed, and an electronic control unit configured to control operation of the fuel valve and the spark plug, the electronic control unit being configured to initiate a speed limitation operation in response to a first position of the throttle valve at engine start-up, wherein the speed limitation operation continues until the throttle valve is moved from its first position.

Abstract: An internal combustion engine (1) may include a combustion chamber (41) into which a mixture (40) of fuel and air is supplied, a spark plug (50) disposed proximate to the combustion chamber (41) to ignite the mixture (40) by generating a spark such that ignition of the mixture drives a piston (6) operably coupled to a crank portion (12) of the engine (1), a speed sensor (102) configured to determine engine speed, and an electronic control unit (100) configured to control operation of the spark plug (50). The electronic control unit (100) may be configured to initiate a speed limitation operation in response to engine speed reaching a cut out speed threshold and to control ignition timing within an operating band (320) of ignition angles prior to engine speed reaching the cut out speed threshold. The speed limitation operation may include skipping application of sparks.

Abstract: Method for optimizing the current A/F settings when accelerating the engine over at least one defined speed interval, the method comprising comparing at least two acceleration times of different A/F ratio that each encompasses at least one defined speed interval. Adjusting the A/F ratio based on the comparison.
