In a general-purpose internal combustion engine connectable to operating machines such as a snowplow, a washing machine and a wood chipper having an electronic control unit that controls operation of the operating machine when connected, there are provided a signal output terminal that is installed in the electronic control unit and outputs a signal generated by the electronic control unit to the operating machine and a signal selector constituted by a personal computer that selects a signal to be outputted by the signal output terminal from among signals in response to manipulation by an operator. The engine can be easily connected with any operating machine without a complicated electronic control unit, thereby improving versatility and convenience.

General-purpose internal combustion engine

An inspection method is conducted after the assembly of an industrial engine is complete. An identification code assigned to an industrial engine is read. Basic engine specification data and device-specific engine specification data that correspond to the read identification code are extracted from a database to a completion inspection unit. Various inspections are conducted on the individual engine by the completion inspection unit on the basis of the extracted basic engine specification data. The device-specific engine specification data of the engine that has passed the inspection is written into memory. A confirmation inspection is then conducted by a device-specific inspection machine to determine whether the engine has the output characteristics required by the mounting device.

Industrial engine completion inspection method

In a failure detection system of coils that produce outputs in response to rotation of a crankshaft of a general-purpose engine (including a power coil that produces an output indicative of the engine speed), the outputs produced by the coils are inputted to determine whether the coils produce the outputs, and it is discriminated that one of the coils (i.e., power coil) has failed when the coil does not produce the output, thereby enabling detection of failure such as wire breaking of the power coil and preventing overrunning of the engine and other such problems.

Coil failure detection system for general-purpose engine

In an auto-choke system for a general-purpose engine, it is determined whether the operator has operated a combination switch to enable ignition in the engine and based on the result of this determination, the operation of a choke motor (actuator) is controlled to regulate the opening of the choke valve, specifically the operation of the choke motor is controlled to fully open the choke valve when ignition is found to be disabled. As a result, jetting of fuel is minimized and flooding prevented when the recoil starter is manipulated with ignition disabled. In addition, the operation of the choke motor is controlled to fully close the choke valve when ignition is found to be enabled, thereby enhancing the starting performance of the engine.

Automatic choke control system for general-purpose engine

The invention makes an output sharing of an engine and an electric motor proper so as to suitably drive a load. When a throttle opening degree variation amount &#x394;V is within a &#x394;V, an engine E can drive a power generator G at a rated revolution speed. A switching circuitis switched in such a manner as to charge a batteryby a generated power. When the opening degree variation amount &#x394;V becomes larger than the &#x394;V, a power assist of operating the power generator G as the electric motor is set to be standby. When the opening degree variation amount &#x394;V is more than &#x394;V(&#x3e;&#x394;V), the power assist is started. In the power assist, an angle advance amount is increased. When acceleration is insufficient, it is possible to further increase a conduction angle in stages.

Engine operated machine

An engine generator apparatus controls the air-fuel ratio in response to the stable output of an oxygen sensor. When a system protectordetects a disorder in a power network, it outputs failure signal. A connection relayis opened in response to the failure signal to release connection of a generator to the power network to release load. When the failure signal is not detected, a load determination sectionurges a proportional valve controllerand the controllerdrives a valvecorresponding to the oxygen density to perform a control of the air-fuel ratio. The load determination sectiondetermines that the load is released by the failure signal to send a notification of no load to the controller. The controllerstops the control of the air-fuel ratio based on the oxygen density in response to this notification.
