    摘要： A vehicle comprising: an internal combustion engine having a cylinder and an exhaust manifold for collecting exhaust gases expelled from the cylinder; an exhaust system configured to channel exhaust gases along a flow path from the exhaust manifold to an exhaust outlet, the exhaust system comprising an exhaust component configured to cause an alteration to engine-generated sound pulses passing through the exhaust component; and a sound bypass device comprising a sound inlet port at a first location on the exhaust system before a first exhaust component along the flow path and a sound outlet port at a second location on the exhaust system after the first exhaust component along the flow path, the sound bypass device being configured to transmit engine-generated sound pulses from the sound inlet port to the sound outlet port whilst preventing flow of exhaust gases from the sound inlet port to the sound outlet port.

    摘要： Constraints on arrangement of catalysts are reduced, and early activation and long-term performance maintenance of the catalysts are both achieved. An exhaust pipe includes a first catalyst provided in a first exhaust pipe extending upward on the side of an exhaust manifold, and a second catalyst provided in a second exhaust pipe that extends downward from a bent pipe extending from the first exhaust pipe and that is adjacent to the first exhaust pipe. The second catalyst is disposed at a position offset to a higher location from an up-down middle position of the first exhaust pipe.

    摘要： The disclosure relates to an exhaust gas cooling device for an internal combustion engine, having a housing which can be connected to an exhaust gas line of the internal combustion engine and has an axis of symmetry and having a Venturi assembly coupled to the housing for introducing exhaust gas and ambient air and having an outlet line emitting an exhaust gas-ambient air mixture into the environment, wherein: the Venturi assembly has a Venturi channel which can be coupled fluidically to the exhaust gas line and an inlet opening delimited by the Venturi channel and the exhaust gas line for ambient air; the Venturi channel is used to conduct an exhaust gas-ambient air mixture and opens, with the inlet opening, into a mixing chamber; the Venturi channel has an outlet opening and the outlet opening has an inflow opening, wherein the outlet opening and the inflow opening are spaced apart from one another; the Venturi channel and the outlet line, with the inflow opening, open into the housing.

    摘要： A vehicle exhaust dissipation system includes a fan unit and one or more processors. A memory is communicably coupled to the one or more processors and stores a fan control module including computer-readable instructions that when executed by the processor(s) cause the processor(s) to, responsive to a determination that an ambient temperature is equal to or below a fan rotor activation temperature, control operation of the fan unit to generate an airflow directed into an exhaust gas exiting the vehicle from a vehicle exhaust opening.
