20120138384 | EXHAUST APPARATUS FOR AN INTERNAL COMBUSTION ENGINE - An exhaust apparatus is provided with an exhaust gas pipe for discharging to the atmosphere an exhaust gas discharged from an internal combustion engine. The exhaust gas pipe has an upstream open end connected to the sound deadening device positioned at the upstream side of an exhaust gas discharging direction, and a downstream open end through which the exhaust gas is discharged to the atmosphere. At least one of the exhaust gas upstream side and the exhaust gas downstream side of the exhaust gas pipe has a diameter expansion structure expanded in diameter toward one of the upstream open end and the downstream open end. The exhaust apparatus comprises a plate provided in the diameter expansion structure to be held in opposing relationship with the discharge direction of the exhaust gas and having an open portion formed to pass through the plate in the discharge direction of the exhaust gas. | 06-07-2012 |
20120168245 | EXHAUST PIPE PART AND EXHAUST APPARATUS FOR INTERNAL COMBUSTION ENGINE - A tail pipe part includes a tail pipe to constitute part of the tail pipe, and has a hollow member connected with the tail pipe in axial alignment with the tail pipe to be positioned within an area covering a node portion in a sound pressure distribution of an air column resonance caused in the tail pipe, and a short pipe included in the hollow member and having a predetermined length to extend in the axial direction of the tail pipe, the short pipe having an open end at the upstream end thereof and a closed end at the downstream end thereof, the closed end being constituted by a bottom plate positioned at almost the same position as that of the node portion in the sound pressure distribution of a standing wave formed by the air column resonance caused in the tail pipe. | 07-05-2012 |
20120180465 | EXHAUST APPARATUS OF INTERNAL COMBUSTION ENGINE - An exhaust gas apparatus of an internal combustion engine is capable of suppressing the sound pressure level from being increased by the air column resonance in the tail pipe. The exhaust gas apparatus being provided with an exhaust gas pipe at the downstream side of an internal combustion engine in the exhaust gas direction of an exhaust gas flow, the exhaust gas pipe having an upstream opening end at one end portion thereof and connected with a sound deadening device at the upstream side in the exhaust gas direction of the exhaust gas flow, and a downstream opening end at the other end portion thereof for exhausting the exhaust gas flow to the atmosphere. | 07-19-2012 |
20120273302 | EXHAUST APPARATUS OF INTERNAL COMBUSTION ENGINE - An exhaust apparatus for internal combustion engines which can reduce exhaust noises, its weight and production cost with no need to provide a sub-muffler. The exhaust apparatus is provided with an inner pipe having the upstream open end and the downstream open end is disposed in the tail pipe, and the upstream open end of the inner pipe is protruded outwardly from the inside of the tail pipe to be extended into the resonance chamber, and thus the upstream open end is closed by the resonance chamber defined by the outer shell of the muffler, the end plate, and the partition plate. | 11-01-2012 |

20140196980 | SILENCING APPARATUS FOR A VEHICLE - A muffler has a flattened cross-sectional shape the width of which is greater than its height. The muffler includes therein a plurality of expansion chambers. The muffler also includes an inlet pipe, an outlet pipe and first to third communication pipes, through which the expansion chambers are open to the outside. All of an opening of the inlet pipe, an opening of the outlet pipe and openings of the first to third communication pipes formed in the muffler are arranged such that they fall between a position separated away from one end of the muffler in its width direction by a ¼ length of the width of the muffler and a position separated away from the end of the muffler by a ½ length of the width. | 07-17-2014 |
20150218998 | EXHAUST HEAT RECOVERY CONTROL DEVICE - An exhaust heat recovery control device includes a recovered heat adjusting unit configured to adjust an amount of heat recovered of exhaust gas by an exhaust heat recoverer recovering heat of exhaust gas and a control unit configured to control the recovered heat adjusting unit so as to prevent or suppress freezing in an exhaust pipe based on a traveling history of a vehicle on which the exhaust heat recovery control device is mounted when the freezing in the exhaust pipe is predicted. | 08-06-2015 |
