摘要： An exhaust emission control device of an engine 1 comprises an NOx storage catalyst 9 which traps and stores NOx in exhaust gas and reduces the stored NOx according to an air fuel ratio of inflowing exhaust gas. A controller 6 determines conditions for discharging the SOx stored in the catalyst 9. When SOx discharge conditions are satisfied and the engine running conditions are in a predetermined SOx discharge running region, the controller 6 performs SOx discharge control of the catalyst 9. As lean air fuel ratio control is prohibited from when SOx discharge conditions are satisfied to when SOx discharge is complete, lean air fuel ratio control is prevented from taking place when the NOx trapping capacity of the catalyst 9 is insufficient, and increase of exhaust emission is thereby prevented.

摘要： An apparatus for an exhaust gas system includes a main exhaust passage, a main catalytic converter disposed in the main exhaust passage, a bypass exhaust passage, a bypass catalytic converter disposed in the bypass exhaust passage, and a valve configured to open or close a section of the main exhaust passage. The bypass exhaust passage bypasses the main exhaust passage between a branch point of the bypass exhaust passage out of the main exhaust passage and a junction with the main exhaust passage at a upstream side of the main catalytic converter. A first sensor indicates a first air-fuel ratio of exhaust gas in the bypass exhaust passage. A second sensor indicates a second air-fuel ratio of exhaust gas flowing into the main catalytic converter. A controller determines whether the valve in the closed configuration leaks exhaust gas based on the first and second air-fuel ratios of exhaust gas.

摘要： An air-fuel ratio control system for an internal combustion engine provided with a NOx trap catalyst which is disposed in an exhaust gas passageway and arranged to trap NOx when the air-fuel ratio of exhaust gas flowing to the NOx trap catalyst is lean and to release and reduce trapped NOx when the air-fuel ratio is rich. The air-fuel ratio control system comprises a sensor for detecting an air-fuel ratio of exhaust gas in the exhaust gas passageway downstream of the NOx trap catalyst. Additionally, a control circuit is provided and configured to cause the engine to operate at a rich air-fuel ratio to accomplish a rich air-fuel ratio engine operation after an engine operation at a lean air-fuel ratio, and continue the rich air-fuel ratio engine operation for a duration even after the sensor has detected that the air-fuel ratio of exhaust gas is rich.

摘要： A first NOx-trapping catalyzer unit is disposed on an upstream part of an exhaust passage. A second NOx-trapping catalyzer unit is disposed on a downstream part of the exhaust passage. A structure is provided that causes the first NOx-trapping catalyzer unit to be exposed to a relatively high temperature environment and causes the second NOx-trapping catalyzer unit to be exposed to a relatively low temperature environment. Each of the first and second NOx-trapping catalyzer units traps NOx when the exhaust gas applied thereto shows a leaner air/fuel ratio and releases and reduces NOx when the exhaust gas applied thereto shows a stoichiometric or richer air/fuel ratio. The first NOx-trapping catalyzer unit shows the basicity that is higher than that of the second NOx-trapping catalyzer unit or the first NOx-trapping catalyzer shows the reducing ability that is lower than that of the second NOx-trapping catalyzer unit.

摘要： An internal combustion engine (1) is provided with a three-way catalytic converter (16) which purifies exhaust gas, a spark plug (6) which ignites a gaseous mixture and a throttle (11) which regulates an intake air flow rate. When the engine (1) is started, the ignition timing of the spark plug (6) is retarded based on the difference of the rotation speed Ne from a target idle rotation speed Net. If the engine rotation speed Ne is higher than the target idle rotation speed even after the ignition timing has reached a retard limit, the ignition timing is fixed to the retard limit and the intake air flow rate is reduced through the throttle (11), thereby forcing the engine rotation speed Ne to converge rapidly to the target idling rotation speed Net while maintaining the ignition timing at the retard limit to ensure rapid temperature increase in the converter (16).

摘要： A power source and a human contacting portion of a portable power tool, with a vibration-proof member and a spacer placed between them, are tightened by fastening and connecting means in the direction approaching each other. The spacer serves to limit compressive power of the vibration proof member which acts between the power source and human contacting portion within effective vibration-proof range of the vibration-proof member by utilizing the fastening and connecting means, This does not cause the vibration absorbing effect of the vibration-proof member to be lost. In addition, there is no need to check the fastening degree achieved by the fastening and connecting means, thus allowing easy attachment of the vibration-proof member thereto. Alternatively, vibration-proof members may be placed between the power source side and the working member side without spacers if the vibration proof members support the power source apart from the working member. To facilitate this construction a universal power transmission, such as a flexible shaft or coupling, is used to transmit rotation power from the power source to the working member in spite of a change in the relative positional relation of the power source to the working member, caused by the vibration-proof member.

摘要： A muffler for an internal combustion engine has an expansion chamber (31, 32) into which exhaust gas from the engine is introduced. The expansion chamber has a double wall (32A), with an inner panel (42) of the double wall (32A) having exhaust gas discharge portions (42A, 42B, 42C, 42D) with respective blowout holes (61, 62, 63, 64) for introducing the exhaust gas from the expansion chamber (32) into an air space (Sb) in the double wall (32A). From the air space (Sb), the exhaust gas is vented to the ambient through a discharge hole (37A) in an outer panel (42) of the double wall (32A ). A spark arrester screen (72) covers the discharge hole (37A).
