Abstract: In a portable inverter power generation apparatus, a rectifying circuit converts AC electric power generated by an electric generator into DC electric power, and an inverter circuit converts the DC electric power into AC electric power. A current sensor detects an AC output current from the inverter circuit. In a first case where the AC output current detected by the current sensor increases from a value lower than a first value to a value higher than the first value, a computer sets a target rotational speed to a value lower than a resonance rotational speed at which an engine resonates until the AC output current detected by the current sensor increases to a second value higher than the first value, and sets the target rotational speed to a value higher than the resonance rotational speed when the detected AC output current increases to the second value.

Abstract: An auto choke device for an engine includes a choke valve for varying the opening of an intake passage of the engine, and a starter motor for starting the engine. Upon activation of the starter motor, the choke valve starts valve opening motion from a fully closed position. The choke valve continues the valve opening motion at a certain valve opening speed until it achieves a start opening set based on the temperature of the engine.

Abstract: A fuel tank has a tank body and a fuel inlet projecting upwardly from the tank body. The fuel tank includes a cylindrical member extending into the tank body, a canister, and a discharging passage in communication with the canister housing an adsorbent for absorbing fuel vapor from the fuel tank. A space between an outer circumferential surface of the cylindrical member and an inner circumferential surface of the fuel inlet is hermetically sealed by a seal. The cylindrical member has a passage for communicating an inside of the cylindrical member with a portion of an outside of the cylindrical member that is lower than the hermetically sealed space. The passage allows air in the tank body to enter the fuel inlet when fuel overflows from the fuel inlet, thereby inhibiting flow of fuel into the canister through the discharging passage.

Abstract: A soundproof type engine generator has an outer shell made by attaching at least a bottom panel to a three-dimensional frame and four wheels in the lower part thereof for transport. The soundproof type engine generator also has handles provided coaxially with opposing wheel shafts of the four wheels, which can be held by a user and facilitate the lifting of the soundproof type engine generator, even if the engine generator is heavy. The wheels of the engine generator are disposed farther outward than the outer shell of the soundproof type engine generator.

Abstract: In a portable inverter power generation apparatus, a rectifying circuit converts AC electric power generated by an electric generator into DC electric power, and an inverter circuit converts the DC electric power into AC electric power. A current sensor detects an AC output current from the inverter circuit. In a first case where the AC output current detected by the current sensor increases from a value lower than a first value to a value higher than the first value, a computer sets a target rotational speed to a value lower than a resonance rotational speed at which an engine resonates until the AC output current detected by the current sensor increases to a second value higher than the first value, and sets the target rotational speed to a value higher than the resonance rotational speed when the detected AC output current increases to the second value.

Abstract: A four-wheel vehicle includes a compact operation lever unit and is constructed so as to secure a sufficient space between the seat and the dashboard. In the four-wheel vehicle, a main body of the operation lever unit includes a first pivoting member, a stopper, and a second pivoting member. The first pivoting member is pivotable between a first position at which a first drive switching mechanism is set to a first mode, and a second position at which the first drive switching mechanism is set to a second mode. The first pivoting member is biased toward the second position. The stopper is arranged to restrict pivoting of the first pivoting member beyond the second position. The second pivoting member is pivotable in conjunction with an operation lever and includes a contact portion that causes the first pivoting member to pivot to a side of the first position against a biasing force.
