    Abstract: In at least one implementation, a method of operating a combustion engine, includes determining a temperature equal or related to a temperature of an engine at an engine start and comparing the determined temperature to a temperature threshold, determining if an engine operating condition exceeds an engine threshold within a threshold time after the engine was started, and if the determined temperature is below the threshold temperature and the engine operating condition remains above the engine threshold and the threshold time has not passed, providing an enriched fuel and air mixture to the engine.

    Abstract: A fuel supply system includes an intake flow passage communicating with an intake port of a gas engine, a fuel shut-off valve assembly for blocking a fuel supply passage to prevent supply of a gas fuel to a fuel mixer, a vacuum flow passage communicating with a vacuum actuator of the fuel shut-off valve assembly and a crank chamber of the gas engine, and means for holding the vacuum flow passage open when the gas engine starts, such that a vacuum produced in the crank chamber is used to actuate the vacuum actuator for switching the fuel shut-off valve assembly to an open position allowing supply of the gas fuel to the fuel mixer.

    Abstract: The invention concerns a method for controlling the fuel supply to an internal combustion engine at start-up, the engine having a fuel supply system. The invention also concerns a carburetor having a fuel supply system including a main fuel path connecting a diaphragm controlled regulating chamber to a main outlet in the region of the venturi section, the main fuel path including an actively controlled fuel valve, and an idling fuel path branching off from the main fuel path downstream of the valve and ending in at least one idling outlet in the region of a throttle valve, the fuel supply system further including a start fuel line starting upstream or downstream of the fuel valve and ending in at least one start fuel outlet to the intake channel.

    Abstract: A fuel enrichment device includes a body forming a first fuel chamber and a second fuel chamber. The second fuel chamber is adapted to contain a predetermined amount of enriching fuel to be provided to an engine. A normally open valve connects the first fuel chamber to the second fuel chamber. A normally closed valve for controls the provision of enriching fuel to the engine. The normally closed valve is open whenever the normally open valve is closed.

    Abstract: A carburetor electronic control system includes: transmission devices coupled to valves for opening and closing an intake path of a carburetor; electric motors that make the valves open and close via the transmission devices; and an electronic control unit for controlling the operation of the electric motors. The interior of a casing joined to one side face of the carburetor is divided by a partition plate into a transmission chamber on the carburetor side and a drive chamber on the opposite side. The transmission devices and the electric motors are housed and held in the transmission chamber and the drive chamber, respectively. Therefore, the transmission devices, the electric actuators, and the electronic control unit can be housed in a common casing, thereby reducing the dimensions of the carburetor electronic control system.

    Abstract: A choke valve is controlled finely suited to the running state of an engine. A throttle valve 8 and a choke valve 9 are provided in series on an intake pipe 6, and the opening degree of the choke valve 9 is controlled by a stepping motor 11. A choke valve opening degree upon start of engine (start opening degree) is determined depending on the engine temperature. The start opening degree judging unit 27 judges whether the start opening degree is closer to the fully closed side or fully opened side. The motor initializing unit 28 initializes the stepping motor 11 at the fully closed side or the fully opened side if the start opening degree is at the fully closed side or the fully opened side, respectively. After choke release, a driving signal in a specified number of steps is issued periodically.
