Abstract
A choke assembly for an internal combustion engine comprising a user interface, a fuel valve, and a choke valve. The choke assembly further comprising an off position, in which the user interface is in a first position, the fuel valve is in a closed position, and the choke valve is in a closed position; a start position, in which the user interface is in a second position, the fuel valve is in an open position, and the choke valve is in the closed position; and a run position, in which the user interface is in a third position, the fuel valve is in the open position, and the choke valve is in an open position.
Claims28
A choke assembly for an internal combustion engine comprising:
- a user interface having a first position, a second position, and a third position;
- a fuel valve coupled to the user interface and having an open position and a closed position, the open position for supplying fuel to the internal combustion engine, and the closed position for preventing the supply of fuel to the internal combustion engine;
- a choke valve having an open position and a closed position, the closed position allowing less air flow to the internal combustion engine than the open position;
- an off position in which the user interface is in the first position, the fuel valve is in the closed position, and the choke valve is in the closed position;
- a start position in which the user interface is in the second position, the fuel valve is in the open position, and the choke valve is in the closed position;
- and
- a run position in which the user interface is in the third position, the fuel valve is in the open position, and the choke valve is in the open position.
A method of operating a choke assembly for an internal combustion engine, the choke assembly including a user interface having a first position, a second position, and a third position, a fuel valve having an open position for supplying fuel to the internal combustion engine and a closed position for preventing the supply of fuel to the internal combustion engine, and a choke valve having an open position and a closed position, the closed position allowing less air flow to the internal combustion engine than the open position, the method comprising:
- positioning the choke assembly in an off position in which the user interface is in the first position, the choke valve is in the closed position, and the fuel valve, which is coupled to the user interface, is in the closed position;
- positioning the choke assembly in a start position in which the user interface is in the second position, the fuel valve is in the open position, and the choke valve is in the closed position;
- and
- positioning the choke assembly in a run position in which the user interface is in the third position, the fuel valve is in the open position, and the choke valve is in the open position.
