| 20110215573 | Exhaust pipe connection structure and exhaust pipe connection method - An exhaust pipe connection structure for interconnecting a connection pipe and an exhaust pipe that are arranged in an exhaust system of an, internal combustion engine. Either of the connection pipe or the exhaust pipe is inserted into the other, and the portion where the connection pipe and the exhaust pipe overlap each other is radially deformed and swaged. | 09-08-2011 |
| 20110215272 | EXHAUST VALVE STRUCTURE - An exhaust valve structure includes: an inner cylindrical portion that forms an introducing passage of exhaust gas and that has a stay member; a valve element that closes or opens the introducing passage; and a wire mesh that is fixed to the stay member and that contacts the valve element when the introducing passage is closed. The wire mesh is formed in a shape such that a diameter of the wire mesh gradually increases toward a downstream side of the introducing passage and a load exerted on the stay member when the valve element contacts the wire mesh is distributed in a diameter-increasing direction in which the diameter of the wire mesh increases. | 09-08-2011 |
| 20100251702 | Heat Recovery System - A plurality of flat tubes formed as a tube having notches by linearly cutting upper and lower parts from a hollow flat circular doughnut shape are stacked to structure a tube laminate. It is attached to a case so that a notch aligns with the notch and faces upward by an exhaust inflow end plate and that a notch aligns with the notch and faces downward by an exhaust outflow end plate. A cutoff valve is provided at an exhaust outflow end of an exhaust communication tube passing through the center of the tube laminate by heat insulation. While an internal combustion engine is warming up, the cutoff valve is closed to cause the exhaust to flow in gaps of the respective flat tubes from upward to downward as a whole and also a heat exchange medium is caused to flow in the respective flat tubes from downward to upward as a whole to have heat exchanged between the exhaust and the heat exchange medium to recover the exhaust heat. | 10-07-2010 |
