    Abstract: An exhaust tract for an internal combustion engine of a motor vehicle includes a first exhaust gas line, which conducts exhaust gases from the internal combustion engine to an exhaust-gas treatment device, and a second exhaust gas line, which forms a bypass line bypassing the exhaust gas treatment device. In order to ensure sufficient treatment of the exhaust gas even in the lean operating mode of an internal combustion engine, at least one first valve and one second valve are provided in series in the bypass line. An exhaust line is provided between the first valve and the second valve to reduce the pressure between the first and second valves. The pressure upstream of the second valve and the pressure downstream of the second valve, or the ambient pressure of the motor vehicle, are determined and negative pressure is applied to the exhaust line such that an exhaust gas flow via the second valve to the outside into the environment of the motor vehicle is prevented.

    Abstract: In a fastening arrangement for the positionally correct fastening of a device to a structural part of a motor vehicle, the at least one screw means is arranged on a tolerance-compensating part, wherein the tolerance-compensating part is fixed to the structural part by means of a joining material which is selected from an adhesive or a plastic liquefied by ultrasonic welding, and wherein the tolerance-compensating part is adjusted in position relative to the structural part. A method for the positionally correct fastening of a device to the structural part of a motor vehicle makes use of a tolerance-compensating part which is joined to the structural part by making use of a joining process in which a joining material is used, the joining process being selected from the group consisting of: adhesive bonding with an adhesive as the joining material, ultrasonic welding with a plastic as the joining material. The tolerance-compensating part is positionally adjusted relative to the structural part during the joining process through the joining material, and the device is fastened to the tolerance-compensating part via at least one screw.

    Abstract: An exhaust system has first and second exhaust gas turbochargers for a V-8 internal combustion engine having an ignition sequence of a 90° crank angle from one cylinder to the next in each of two cylinder banks. The exhaust system includes a first-through-fourth exhaust lines from the cylinders to the two exhaust gas turbochargers, with two cylinders respectively being assigned to an exhaust line. One exhaust turbocharger is respectively assigned to two exhaust lines. The two cylinders assigned to an exhaust line having an ignition interval of a 360° crank angle. The first and the second exhaust lines assigned to an exhaust gas turbocharger having an ignition sequence displaced with respect to one another by a 180° crank angle. As a result, the opening phase of the charge cycle intake valves can be prolonged, which leads to a significantly higher power of the internal combustion engine.

    Abstract: An exhaust system has first and second exhaust gas turbochargers for a V-8 internal combustion engine. A first cylinder bank includes four cylinders arranged in series side-by-side, and a second cylinder bank situated opposite the first cylinder bank includes the other four cylinders arranged in series side-by-side. The internal combustion engine has an ignition sequence of a 90° crank angle from one cylinder to the next. The exhaust system includes a first, a second, a third and a fourth exhaust line from the cylinders to the two exhaust gas turbochargers, with two cylinders respectively being assigned to an exhaust line. One exhaust turbocharger is respectively assigned to two exhaust lines. The two cylinders assigned to an exhaust line having an ignition interval of a 360° crank angle. The first and the second exhaust lines assigned to an exhaust gas turbocharger having an ignition sequence displaced with respect to one another by a 180° crank angle. As a result, the opening phase of the charge cycle intake valves can be prolonged, which leads to a significantly higher power of the internal combustion engine.
