    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: A two stroke engine having an exhaust port formed in the cylinder wall. At the upper portion of the exhaust port, there is provided a rotary type exhaust timing control valve which is adapted to be actuated by a centrifugal governor device to control the exhaust timing in accordance with the engine speed. The centrifugal governor device has a governor shaft which extends coaxially with the engine crankshaft and directly connected at one end with the adjacent end of the crankshaft.

    Abstract: A valve opening and closing timing control apparatus includes: a driving side rotator configured to rotate synchronously with a crankshaft of an internal combustion engine; a driven side rotator disposed coaxially with a rotation axis of the driving side rotator and configured to rotate integrally with a valve opening and closing camshaft; a phase controller configured to control a relative rotation phase between the driving side rotator and the driven side rotator by supply and discharge of a fluid; and a torsion spring configured to attain a biasing force to displace the relative rotation phase between the driving side rotator and the driven side rotator in a predetermined direction. The driving side rotator is fastened to a cover-shaped plate, and the torsion spring includes a first arm and a second arm.

    Abstract: A method for operating a reciprocating internal combustion engine in an engine braking mode includes, in a working cycle of the engine braking mode, a first outlet valve of a first cylinder is closed for a first time, then opened for a first time, and subsequently closed for a second time, and then opened for a second time, in order to thereby discharge gas that has been compressed in the first cylinder from the first cylinder by a cylinder piston. The outlet valve is held open after the first opening and prior to the second dosing long enough for the cylinder to be filled with gas that flows out of a second cylinder via at least one outlet channel, where when the engine braking mode is activated, at least one camshaft for activating at least one gas exchange valve of the reciprocating internal combustion engine is adjusted.

    Abstract: A gas-powered tool motor includes a combustion chamber with an intake valve at one end, an exhaust valve at another end, and a control plate or control valve between two portions of the combustion chamber. A piston or other positive displacement device is in communication with the combustion chamber. The intake and exhaust valves have closure members that are movable along a common axis in tandem between collective open positions for recharging the combustion chamber with the fuel and air mixture and collective closed positions for detonating the fuel and air mixture in the combustion chamber and displacing the positive displacement device. The control plate or control valve supports limited air flows from a first portion of the combustion chamber to a second portion of the combustion chamber even in the closed position of the control valve for supporting two-stage combustion.
