Abstract: 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.

Abstract: Provided is a variable valve device for an internal combustion engine, capable of improving engine characteristics by increasing the maximum valve lift of an intake valve to a large valve lift while preventing excessive lost motion operation of lost motion mechanisms. The variable valve device includes intake- and exhaust-side swing arms that pivot to open and close intake valves (3a, 3b) and exhaust valves (61a, 61b) in two cylinders #1, #2, intake- and exhaust-side hydraulic lash adjusters (10a, 10b, 65a, 65b) that serve as pivot points of the respective swing arms, a variable valve system that continuously varies valve lift characteristics of the intake valves and lost motion mechanisms (11) that stop opening and closing of the intake exhaust valves by lost motion of the intake- and exhaust-side hydraulic lash adjusters on the cylinder #1. The maximum valve lifts of the intake valves are set larger than valve lifts of the exhaust valves. The minimum valve lifts of the intake valves are set smaller than the valve lifts of the exhaust valves.
