| 20090313982 | EXHAUST SYSTEM FOR MOTORCYCLE - An exhaust system for a motorcycle is configured to enhance output while maintaining a necessary noise level. The exhaust system includes an exhaust pipe connected to an engine, and a silencer connected to the exhaust pipe. The silencer includes a hermetically sealed outer cylinder and an inner cylinder disposed within the outer cylinder so as to extend along an axis of the outer cylinder. The outer cylinder has a front end portion connected to the exhaust pipe and a rear end portion opened toward the atmosphere. The inner cylinder includes a reduced diameter portion with a diameter which becomes smaller in the downstream direction, a throttle portion with a constant diameter, the throttle portion being connected to the reduced diameter portion, and an enlarged diameter portion connected to the throttle portion with a diameter which becomes larger in the downstream direction. | 12-24-2009 |

| 20100236226 | Exhaust system and method for an internal combustion engine and a generator set utilizing same - This invention discloses an exhaust system for an internal combustion engine and a generator set utilizing same. The exhaust system reduces jet noise and temperature of a first exhaust gas from the internal combustion engine. The exhaust system comprises an inlet, a chamber, and an outlet. The inlet is capable of generating an airflow into the chamber where the first exhaust gas is merged with said airflow into a second exhaust gas, thereby reducing the noise and temperature of the first exhaust gas. The chamber includes sound absorbing material to further reduce the noise. The inlet is decoupled from the internal combustion engine to reduce vibration noise, and is made up of a high temperature elastomer to accommodate extreme exhaust gas temperatures. | 09-23-2010 |

| 20130042600 | SOUND ATTENUATING HEAT EXCHANGER FOR AN INTERNAL COMBUSTION ENGINE - A sound attenuating heat exchanger for an internal combustion engine includes a housing, a barrier wall and a fin. The housing includes an exhaust inlet, an exhaust outlet, a coolant inlet and a coolant outlet. The exhaust inlet is connected to the exhaust outlet by an exhaust flow passage. The coolant inlet is connected to the coolant outlet by a coolant flow passage. The barrier wall fluidly separates the exhaust flow passage from the coolant flow passage. The fin extends from the barrier wall into the exhaust flow passage, and includes a resonator adapted to attenuate sound waves traveling through exhaust gas within the exhaust flow passage. The barrier wall and the fins are adapted to exchange heat energy between the exhaust gas flowing through the exhaust flow passage and coolant flowing through the coolant flow passage. | 02-21-2013 |
| 20140053540 | BRACKET FOR AN AFTER-TREATMENT COMPONENT - A bracket for connecting an after-treatment component to a frame is disclosed. The bracket may have a clevis connectable to the after-treatment component. The bracket may also have a front link coupler. The front link coupler may have a tang connected to the clevis. The front link coupler may also have a first flange extending outward from the tang and a second flange extending outward from the tang opposite the first flange. In addition, the front link coupler may have a third flange spaced apart from the first flange and extending outward from the tang and a fourth flange spaced apart from the second flange and extending outward from the tang opposite the third flange. The first, second, third, and fourth flanges may be connectable to the frame. | 02-27-2014 |
| 20140250874 | EXHAUST DEVICE FOR MULTICYLINDER ENGINE - An exhaust device includes a plurality of independent exhaust passages connected to an exhaust port of one cylinder or a plurality of cylinders that are non-sequential in exhaust order, and a mixing pipe into which exhaust that has passed through the respective independent exhaust passages flows. The downstream ends of the respective independent exhaust passages are connected in a bundled form to the upstream end of the mixing pipe. A cavity expansion chamber is disposed in an exhaust passage downstream from the mixing pipe. The cavity expansion chamber is disposed in a position (at a distance L2) such that, in the intermediate speed range, a negative pressure wave generated due to an exhaust pressure wave generated by opening an exhaust valve being reflected by the cavity expansion chamber reaches the exhaust port during an overlap period of the exhaust valve and an intake valve of the cylinder. | 09-11-2014 |
| 20140352287 | EXHAUST GAS TREATMENT DEVICE - The invention relates to an exhaust gas treatment device for an exhaust system of a combustion engine, more preferably of a road vehicle, with a housing enveloping at least one interior space, and with at least one through-pipe penetrating the interior space without interruption and which at two fastening points distant from each other is connected to the housing in a fixed manner. | 12-04-2014 |
