摘要： A passive prechamber spark plug for use in a combustion chamber of a vehicle engine includes an upper prechamber having an upper opening where the upper prechamber is connectable to the combustion chamber via the upper opening. An air ignition spark is formable via an upper air spark gap. A central electrode is disposed in an upper region of the upper prechamber where a base of the upper prechamber opposite the upper region is an insulator. An electrically conductive element or a slot is guided by the insulator continuously from the upper prechamber into a lower region under the base and the lower region is either a lower prechamber or is arrangeable directly in the combustion chamber. An earth electrode is disposed in the lower region such that a lower air-surface gap spark gap is formed between the earth electrode and the electrically conductive element or the slot.

摘要： An exhaust system is provided for an internal combustion engine having at least a first and a second cylinder, wherein the first cylinder is assigned a first exhaust gas pipe and the second cylinder is assigned a second exhaust gas pipe. The first exhaust gas pipe is assigned a first muffler, and the second exhaust gas pipe is assigned a second muffler. A first damping pipe branches off from the first exhaust gas pipe upstream of a first shut-off element. The damping pipe firstly opens into a first reflection chamber and is subsequently led through the first muffler and opens into the second exhaust gas manifold downstream of a second shut-off element. A second damping pipe branches off from the second exhaust gas pipe upstream of a second shut-off element. The second damping pipe firstly opens into a second reflection chamber and is subsequently led through the second muffler and opens into the first exhaust gas pipe downstream of the first shut-off element.

摘要： An exhaust flap for an exhaust system of a motor vehicle, which has an internal combustion engine and an electronic processing device for a closed-loop control of the internal combustion engine, has a valve element, an actuator for moving the valve element, and a dedicated electronic processing device. The dedicated electronic processing device is configured to receive a first signal which is provided by the electronic processing device of the motor vehicle and which characterizes a first position of the valve element, generate a second signal which characterizes a second position of the valve element as a function of the received first signal, and transmit the second signal to the actuator. The actuator moves the valve element into the second position based on the received second signal.

摘要： An exhaust-gas system for a vehicle having an internal combustion engine includes a Helmholtz resonator and two exhaust-gas lines extending toward the resonator. The resonator has two neck openings to a resonator volume. Each neck opening is coupled to one of the exhaust-gas lines, and the resonator is tuned to damp a dominant engine order.
