Abstract: A general engine throttle apparatus includes a throttle body 12, a throttle valve 13, a throttle shaft 14, a driven gear 24, an electrically driven motor 15, and a detected body block 26. The throttle valve 13 opens and closes an intake air introduction hole 11. The throttle shaft 14 holds the throttle valve 13 and is rotatably supported by a holding hole 16 of the throttle body 12. The electrically driven motor 15 transmits a rotation operation force to the driven gear 24. The detected body block 26 is attached to another end part in an axial direction of the throttle shaft 14, and a state of the throttle shaft 14 is detected by a sensor. The driven gear 24 is integrally formed on one end side in the axial direction of the throttle shaft 14. The detected body block 26 is formed to have a maximum outer diameter that is smaller than a minimum inner diameter of the holding hole 16.

Abstract: A throttle apparatus includes a throttle body (12), a throttle valve (13), a throttle shaft (14), an electrically driven motor (15), a drive gear (23), a driven gear (24), a middle gear (25), and a sensor block (19). The middle gear (25) is held by the throttle body (12) such that a gear shaft is displaced from an imaginary straight line (V) connecting together a motor shaft and the throttle shaft (14). A gear arrangement projection part (34) that projects outward by a displacement amount of the middle gear (25) and a connector arrangement projection part (35) that projects to a same side as the gear arrangement projection part (34) at a position adjacent to a motor housing part (12b) side of the gear arrangement projection part (34) are formed on an outer surface of the throttle body (12). The motor connector (36) is arranged on the connector arrangement projection part (35) such that the motor connector (36) is in parallel with an axis center of the motor shaft and faces another end side of the throttle body (12). The sensor connector (20) is arranged on the sensor block (19) such that the sensor connector (20) is directed toward the axis center from a direction that is orthogonal to the axis center of the motor shaft.

Abstract: In a control apparatus for a general-purpose internal combustion engine including a generator as a power supply, the generator includes a main generator coil supplying power to the stepping motor, and an auxiliary generator coil supplying power to an ignition device of the engine. The apparatus includes ignition timing controller for, when starting the engine by a manual starter, detecting that an engine speed reaches or exceeds a predetermined engine speed not exceeding a connecting rotation speed of a centrifugal clutch to retard an ignition timing of the engine, thereby suppressing increase in the engine speed to less than the connecting rotation speed, and for restoring the ignition timing to its normal timing after a predetermined time elapses from start of retarding the ignition timing. Accordingly, it suppresses overshooting of an engine speed above the connecting rotation speed even if a delay occurs in closing a throttle valve by a delay in activating the motor.

Abstract: An engine fuel supply apparatus includes: a fuel chamber provided in a carburetor; a first communication passage for opening the interior of the fuel chamber to the atmosphere; a second communication passage for communicating the interior of the fuel chamber with the interior of a Venturi section; and a passage switching section capable of switching between the first and second communication passages and mechanically connected to the main switch so that it can operate in response to the main switch shifting between an ignition position and a stop position. The passage switching section switches the second communication passage to the first communication passage in response to the main switch shifting from the stop position to the ignition position and switches the first communication passage to the second communication passage in response to the main switch shifting from the ignition position to the stop position.
