An engine comprising a camshaft, the engine coupleable to an auxiliary device driven from the camshaft, the camshaft comprising: a plurality of valve cams each configured to actuate a respective intake valve or exhaust valve of the engine, an angular orientation of the valve cams about the rotational axis of the camshaft defined by the operational requirements of the valves; and an auxiliary device cam configured to actuate a drive element of the auxiliary device via one or more cam lobes, the auxiliary device cam having an angular orientation about the rotational axis of the camshaft, and the drive element having an angular orientation about the rotational axis of the camshaft, wherein the angular orientation of the drive element of the auxiliary device is selected respective to the angular orientation of the valve cams such that each actuation event of the auxiliary device occurs between two successive valve actuation events.

A vehicle includes at least one sensor generating a signal to control an operation of an internal combustion engine; and a control unit configured to store a control parameter to control an operation of the internal combustion engine, and to correct the control parameter based on an output of the at least one sensor. The control unit stops correcting the control parameter while the vehicle is at a halt, and the power generator is generating electric power by driving of the internal combustion engine.

An electronic ignition system for a portable gasoline tool includes a voltage boosting device, a spark plug connected with an output of the voltage boosting device, a DC power source, and a controller electrically connected with the DC power source and connected with the voltage boosting device. The controller controls an ignition voltage and an ignition advance angle. A related portable gasoline tool includes a body, a cylinder located in the body, a piston movable to and fro within the cylinder, a crankshaft co-moved with the piston, and a flywheel located on the body and driven by the crankshaft to rotate.

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.

In a package-storage type engine generator, a package (2) is partitioned into an upper section and a lower section. An engine (11) and a generator (12) are disposed in the lower section, and a radiator (42) and a radiator fan (43) are disposed in the upper section. An upper/lower partition member (32) partitions the package (2) into the upper section and the lower section. A portion of the upper/lower partition member (32), which faces the radiator fan (43), is formed in a downward inclined shape from a center portion to an outer edge portion of the package.

An engine including a fuel tank, a carburetor, a speed control lever, and a transport valve. The carburetor includes a throttle valve movable between a first throttle position and a second throttle position. The speed control lever is coupled to the throttle valve and is movable between a first position corresponding to the first throttle position and a second position corresponding to the second throttle position. The transport valve is fluidly coupled between the fuel tank and the carburetor, and includes a valve element moveable between an open valve position allowing fuel flow between the fuel tank and the carburetor, and a closed valve position preventing fuel flow between the fuel tank and the carburetor. Movement of the speed control lever to the second position moves the valve element to the closed valve position to stop fluid flow between the fuel tank and the carburetor.
