摘要： Systems and methods for operating an engine that includes an exhaust tuning valve in its exhaust system are described. In one example, a position of the exhaust tuning valve may be adjusted to reduce a possibility of the exhaust tuning valve becoming stuck due to freezing water. In particular, the exhaust tuning valve may be cycled as ambient temperature approaches a temperature at which water freezes.

摘要： An engine exhaust system includes a catalytic converter, an exhaust conduit connected upstream of the catalytic converter, and an oxygen sensor extending into the exhaust conduit at a first axial position of the exhaust conduit. A valve is located within the exhaust conduit at the first axial position. The valve includes a movable throttle plate having a bypass notch formed on a periphery of the plate. The valve has an open position, and a closed position in which the bypass notch is placed adjacent to the oxygen sensor to guide exhaust over the oxygen sensor.

摘要： A system for controlling a sound level of a prime mover permitted to emanate from or within a vehicle includes a global positioning satellite (GPS) receiver operable for receiving a GPS signal and a sound control device. The sound control device is operable for increasing or decreasing a sound level of the prime mover in response to a control signal. A controller in communication with the GPS receiver includes a calendar and clock, and is programmed to execute a method, including receiving the GPS signal via the GPS receiver, and determining an actual location of the vehicle using the GPS signal. The controller also determines an actual date and time of day using the calendar and the clock, respectively, and transmits the control signal to the sound control device to increase or decrease the sound level using at least one of the actual location, date, and time of day.

摘要： An apparatus and method are provided for a drone elimination muffler to attenuate drone exhibited by engine exhaust systems. The drone elimination muffler comprises a hollow canister having a length and a diameter, and a tuned port comprising a first end connected to the canister and a second end connected to the exhaust system. The canister operates in concert with the tuned port as a dampener configured to substantially attenuate exhaust drone, or resonance, at one or more frequencies of engine operation. A valve is configured to switch the drone elimination muffler between a closed state in which the exhaust system operates without acoustic influence due to the drone elimination muffler, and an open state in which the drone elimination muffler directly influences the acoustic properties of the exhaust system.

摘要： An exhaust-gas muffler includes a casing and a relief valve. The relief valve is provided to open when a pressure of an upstream exhaust-gas chamber is equal to or higher than a predetermined value. The relief valve includes a shutter, a spring, and a seal member. The shutter member is provided to face an open end of a gas passage provided between an upstream exhaust-gas chamber and a downstream exhaust-gas chamber. The spring is to bias the shutter member in a direction in which the gas passage is closed. The seal member is disposed on a downstream side of the gas passage. The seal member is made of a metal mesh material and has a disc shape to cover the open end of the gas passage.
