摘要： A silencer for a two-stroke motor of a power tool, including a silencer inlet to which adjoins a flow channel of channel length so that the flow channel can be connected to an outlet of a combustion chamber of the two-stroke motor, whereby the flow channel at the channel end opposite the silencer inlet opens out into a first chamber of depth, between the silencer inlet and the first chamber the flow channel is so flow-beneficially designed, that due to its mass inertia the exhaust gas flowing into the silencer inlet predominantly flows into the first chamber and after filling the first chamber flows back again thereby creating a counterpressure in the direction of the combustion chamber, so that in spite of small geometric dimensions it provides a periodically actin counterpressure on the outlet of the combustion chamber of the two-stroke motor.

摘要： A muffler is disclosed. In the muffler a throttling device that is controlled by the energy of the airflow to be muffled is provided in a pipeline of the airflow that needs to be muffled. The muffler is adjusted by itself according to random variety of the pulsing airflow, and can eliminate or reduce effectively the pulsation of the airflow and the related noise in the range of the low frequency and the middle frequency. The muffling effect of the muffler has no correlation with the volume of the muffler, and therefore the volume of the muffler can be reduced.

摘要： An exhaust system of a multi-cylinder internal combustion engine, particularly in a motor vehicle, has a first exhaust-gas line for receiving the exhaust gas from a first cylinder group of the internal combustion engine, a second exhaust-gas line for receiving the exhaust gas from a second cylinder group of the internal combustion engine, an exhaust-gas expansion chamber and an exhaust-gas outlet line, leading out of the exhaust-gas expansion chamber. The first and second exhaust-gas lines lead into an exhaust-gas mixing chamber which is coupled in gas flow communication with the exhaust-gas expansion chamber, so that exhaust gas can expand via the perforation of the exhaust-gas mixing chamber, into the exhaust gas expansion chamber.

摘要： A muffler comprises a casing and an exhaust pipe penetrating the casing. An exhaust gas chamber 4 is defined between the outer wall surface of the exhaust pipe and the inner wall surface of the casing. In the exhaust pipe positioned in the casing, an enlarged chamber for accommodating a particulate filter is formed. A downstream side portion of the exhaust pipe and the exhaust gas chamber are communicated with each other by a branch pipe. A communicating port is formed on the wall of an upstream side portion of the exhaust pipe positioned in the exhaust gas chamber. Until the pressure difference between the upstream and downstream of the communication control valve reaches a threshold value, the communication control valve is kept closed to close the communicating port and, thus, the exhaust gas flows through the particulate filter. When the pressure difference has reached the threshold value, the communication control valve is opened by the pressure in the upstream side portion to open the communicating port and, thus, a part of the exhaust gas bypasses the particulate filter.
