摘要： A tuned cavity is provided to receive the exhaust gases from an internal combustion engine, the cavity being proportioned so that an acoustical standing wave is set up therein at the principal frequency of the noise output of the engine, pressure nodes of this wave appearing at the opposite ends of the cavity. The gas from the cavity is passed through a series of apertures spaced therealong into a chamber in a manner so as not to significantly affect the standing wave pattern. The gas is then passed from the chamber to a section comprising flexible diaphragm means which acts as an inertial damper and a flap valve, the gas being exhausted into the ambient atmosphere from the diaphragm section.

摘要： PROBLEM TO BE SOLVED: To reconcile the enhancement of the exhaust capability of condensed water collected in a muffler and decrease in back pressure of an engine. SOLUTION: This muffler is equipped with an inlet pipe 9 for introducing exhaust gas; an outlet pipe 12 for exhausting the exhaust gas; a valve 17 for opening/closing an inflow port 15 of the exhaust gas flowing in the outlet pipe 12 according to an operation state; and a bypass passage 19 having the cross section area smaller than that of the outlet pipe 12 and communicating with the outlet pipe 12 by bypassing the valve. In an onboard state, an inflow port 20 of the bypass passage 19 is opened so as to locate on the lower side than the inflow port 15 of the outlet pipe 12. The cross section area of the bypass passage 19 is set smaller than the cross section area of the inflow port 15 which is opened/closed with the valve 17.

摘要： PROBLEM TO BE SOLVED: To remarkably obtain both a muffling effect in low engine speed and a back pressure elevation preventing effect in high engine speed. SOLUTION: An exhaust pipe 1 is divided into two, a main passage 3 and a bypass passage 4. This valve element structure is to timely open and close the bypass passage 4 and is provided with a valve element 10 capable of opening and closing the bypass passage 4. A spring 11 for energizing the valve element 10 to close the bypass passage 4, and a magnet 12 for acting a magnetic force on a retainer 17 closing the bypass passage 4 (this is integrated with the valve element 10) to retain a closed state. In this valve element structure, adjusting the magnetic force of the magnet 12 increases force for opening the closed valve element 10; and adjusting the energizing force of the spring 11 reduces force for further widely opening the opened valve element.

摘要： PROBLEM TO BE SOLVED: To provide an active noise controller in which noise in a duct is precisely detected by reducing the adverse effects caused by the air flow in the duct and the vibration of the duct, making the frequencies of the standing waves which consists of muffling sound waves produced in the direction of the duct cross surface so as to muffle sound in a wide frequency range for a wide diameter duct. SOLUTION: A sensor 16 is placed in the space that is communicative with a duct 11 inner space, is arranged with a space having a cross section shape of an isosceles triangle having one side along the longitudinal direction of the duct 11 outside the duct 11 inner space so as to detect the noise propagating in the duct 11 or the muffling condition in the duct 11. Sound muffling speakers are placed on the faced walls of the duct 11 opposite each other. The speakers radiate sound waves having the same phases and the same sound pressure with each other into the duct and the frequencies of the standing waves produced in the direction of the cross section surface are made higher.
