摘要： An exhaust gas purification device for a general-purpose engine includes a crankcase and a cylinder block provided continuously on an upper portion of the crankcase and inclined to one lateral side of the crankcase. A catalytic converter is provided in an exhaust muffler of the engine. A downstream end of a secondary air introduction pipe is connected to an exhaust pipe upstream of the muffler. A dedicated air filter is connected through a one-way valve to an upstream side of the secondary air introduction pipe. The filter is disposed between the crankcase and a lower surface of the cylinder block. The secondary air introduction pipe is arranged so as to meander on one side of the cylinder block. Accordingly, the device can be employed without increasing an outer size of the engine, and can also securely introduce secondary air into an exhaust system, thereby enhancing an exhaust gas purifying effect.

摘要： The device includes an exhaust passage having an upstream end connected to an exhaust port of the engine and a downstream end provided with a catalytic converter, a secondary air passage having a downstream end connected to an intermediate point of the exhaust passage and an upstream end communicating with the atmosphere, and a reed valve provided in an upstream end of the secondary air passage to permit air flow from the atmosphere to the exhaust passage but not in the opposite direction. The reed valve has a resonance frequency which is z times the prescribed exhaust frequency of the engine, where z is an integer. The length of the secondary air passage is selected that the pulsation effect of air in the secondary air passage may be advantageously utilized.

摘要： An engine generator has an opening and closing mechanism including: a control shaft provided to a valve shaft of a choke valve to be rotatable relative thereto within a predetermined angular range; an urging member urging the valve shaft relative to the control shaft in a direction in which an opening degree of the choke valve decreases; a restriction mechanism that sets a minimum opening degree of the choke valve by restricting a range of rotation of the control shaft; a choke operating portion which, upon operation, drives the restriction mechanism in a direction in which the minimum opening degree of the choke valve decreases; and a negative pressure mechanism driven by a negative pressure generated during an operation of the engine to cause the control shaft to rotate to increase the minimum opening degree of the choke valve within the range of rotation restricted by the restriction mechanism.
