An engine-driven working machineis a generator in which an outer caseis formed to be substantially rectangular in plan view that extends in a longitudinal direction, and an engineis housed in an insideof the outer case. In the generator, a crankshaftis disposed to intersect the longitudinal direction of the outer case. Further, an intake portand an exhaust portare disposed in the longitudinal direction of the outer case. Furthermore, a carburetoris disposed at a side of the intake port, and a muffleris disposed at a side of the exhaust port

A fuel-tank-equipped working machine is provided, which is capable of securing a fuel tank to be large in a state where the fuel-tank-equipped working machine is secured to be compact. A generatoras a working machine includes a fuel tanksupported at an outer case. The working machineincludes a tank openingthat is formed at the outer case, a mounting concave portionthat is formed on the fuel tank, and a cushion portionthat is capable of being housed in the mounting concave portion. The tank openingis formed so as to be able to expose an upper half partof the fuel tankto an outsideof the outer case. Further, the cushion portionhas a fitting groovecapable of being fitted to an opening rimof the tank opening

Fuel-tank-equipped working machine

An engine-driven working machine capable of favorably reducing exhaust sound (that is, noise) is provided. An engine-driven working machineis a generator in which an engineand a mufflerare housed in an insideof an outer case. The generatorincludes a tail pipethat is provided at a lower portionof the muffler, a discharge portthat is disposed above the tail pipe, and a baffle platethat is disposed to face the discharge port. The discharge portis formed in the outer case. Further, cooling air that is sent from a cooling fanis guided to below the mufflerwith the baffle plate

An engine-driven working machine capable of reducing an opening of an outer case to be small, and decreasing the number of components is provided. An engine-driven working machineis a generator in which an inverteris provided at a suction side of a cooling fan, and a fuel tankis provided over the inverter. The generatorincludes an intake portthat is formed in an outer case, and a first air guide passagethat is formed by a tank bottom portionof the fuel tank. The intake portis formed in a lower side partof a tank front wall, in the outer case. The first air guide passageis formed by the tank bottom portionthat is inclined with a falling gradient toward the inverterfrom the intake port

An engine-driven working machineis a generator where a working unitincluding an engineand a power generating unitis housed in an outer case. A plurality of lower support meansare included in the generator. The lower support meansincludes a first vibration isolating support portiondisposed between the working unitand the outer case, a second vibration isolating support portionformed integrally with the first vibration isolating support portion, and a groove portionformed between the first vibration isolating support portionand the second vibration isolating support portion. The working unitis supported with the first vibration isolating support portion. The outer caseis supported with the second vibration isolating support portion. A fitting portionof the outer caseis fitted to the groove portion

Engine-driven working machine housed in outer case with vibration isolating support

An outboard motor configured so that an engine is covered by an engine cover, an intake opening is provided to both sides of the engine cover, and air drawn into the engine cover from the intake opening is introduced to a throttle body. A discharging/interference-type muffler is provided partway along an intake channel for guiding air from the intake opening to the throttle body. The discharging/interference-type muffler is provided vertically in the interior of the engine cover, and the interior of the discharging/interference-type muffler is divided in two in the vertical direction.

Outboard motor

A portable engine generator includes a power generation unit operating an engine to generate electricity and a negative pressure fuel cock using a negative pressure in a crank chamber as an operating negative pressure to supply fuel to the engine. The negative pressure fuel cock is located on a side opposite to a negative pressure take-out port of the crank chamber with respect to a position of the power generation unit when the portable gas-engine generator is turned over, and so as to be located at a position higher than the negative pressure take-out port when the portable gas-engine generator is in an upright posture.

Portable engine generator

An outboard engine unit capable of efficiently cooling the interior of an engine cover is disclosed. The outboard engine unit includes a cooling opening capable of guiding air to an interior from an upper part of the engine cover, a first intake channel having a first outlet open to an upper front end and communicating with the opening, a partition wall disposed so as to be oriented substantially in a perpendicular direction below the first outlet; and a second intake channel extending substantially in the perpendicular direction along a rear wall of the engine cover rearward of the partition wall. The outboard engine unit is configured so that air directed from the cooling opening to the interior of the engine cover is directed to the throttle unit via the second cooling air intake channel.

Outboard engine unit

Engine cooling structure directs cooling air, introduced into a case by operation of a fan, to a cylinder block of an engine and then discharges the cooling air out of the case through an outlet port along meandering flow passages. Case cooling structure directs cooling along the inner surface of the case. Further cooling flow passage directs the air to vertically-oriented heat radiating fins so that the cooling air flows upward along the fins and then is discharged through the outlet port. Metal cooling-fan cover is supported by the lower cover via mounting members, and a resin-made cover guide is fastened to the engine together with supporting portions and interposed between the fan cover and the engine.
