1/04 Carburettors with means for facilitating engine's starting or its idling below operational temperatures the means to facilitate starting or idling being auxiliary carburetting apparatus able to be put into, and out of, operation, e.g. having automatically-operated disc valves
1/06 Carburettors with means for facilitating engine's starting or its idling below operational temperatures the means to facilitate starting or idling being auxiliary carburetting apparatus able to be put into, and out of, operation, e.g. having automatically-operated disc valves having axially-movable valves, e.g. piston-shaped
1/08 Carburettors with means for facilitating engine's starting or its idling below operational temperatures the means to facilitate starting or idling becoming operative or inoperative automatically (in connection with auxiliary carburetting apparatus F02M 1/04)
1/10 Carburettors with means for facilitating engine's starting or its idling below operational temperatures the means to facilitate starting or idling becoming operative or inoperative automatically (in connection with auxiliary carburetting apparatus F02M 1/04) dependent on engine temperature, e.g. having thermostat
1/12 Carburettors with means for facilitating engine's starting or its idling below operational temperatures the means to facilitate starting or idling becoming operative or inoperative automatically (in connection with auxiliary carburetting apparatus F02M 1/04) dependent on engine temperature, e.g. having thermostat with means for electrically heating thermostat
1/14 Carburettors with means for facilitating engine's starting or its idling below operational temperatures the means to facilitate starting or idling becoming operative or inoperative automatically (in connection with auxiliary carburetting apparatus F02M 1/04) dependent on pressure in combustion-air- or fuel-air-mixture intake (F02M 1/1 takes precedence)
1/16 Carburettors with means for facilitating engine's starting or its idling below operational temperatures Other means for enriching fuel-air mixture during starting; Priming cups; using different fuels for starting and normal operation
1/18 Carburettors with means for facilitating engine's starting or its idling below operational temperatures Other means for enriching fuel-air mixture during starting; Priming cups; using different fuels for starting and normal operation Enriching fuel-air mixture by depressing float to flood carburettor
3/00 Idling devices for carburettors (with means for facilitating idling below operational temperatures F02M 1/00)
3/02 Idling devices for carburettors (with means for facilitating idling below operational temperatures F02M 1/00) Preventing flow of idling fuel
3/04 Idling devices for carburettors (with means for facilitating idling below operational temperatures F02M 1/00) Preventing flow of idling fuel under conditions where engine is driven instead of driving, e.g. driven by vehicle running down hill
3/045 Idling devices for carburettors (with means for facilitating idling below operational temperatures F02M 1/00) Preventing flow of idling fuel under conditions where engine is driven instead of driving, e.g. driven by vehicle running down hill Control of valves situated in the idling nozzle system, or the passage system, by electrical means or by a combination of electrical means with fluidic or mechanical means
3/05 Idling devices for carburettors (with means for facilitating idling below operational temperatures F02M 1/00) Preventing flow of idling fuel under conditions where engine is driven instead of driving, e.g. driven by vehicle running down hill Pneumatic or mechanical control, e.g. with speed regulation
3/055 Idling devices for carburettors (with means for facilitating idling below operational temperatures F02M 1/00) Preventing flow of idling fuel under conditions where engine is driven instead of driving, e.g. driven by vehicle running down hill Fuel flow cut-off by introducing air, e.g. brake air, into the idling fuel system
3/06 Idling devices for carburettors (with means for facilitating idling below operational temperatures F02M 1/00) Increasing idling speed
3/07 Idling devices for carburettors (with means for facilitating idling below operational temperatures F02M 1/00) Increasing idling speed by positioning the throttle flap stop, or by changing the fuel flow cross-sectional area, by electrical, electromechanical or electropneumatical means, according to engine speed
3/08 Idling devices for carburettors (with means for facilitating idling below operational temperatures F02M 1/00) Other details of idling devices (fighting ice-formation by heating idling ports F02M 15/02)
3/09 Idling devices for carburettors (with means for facilitating idling below operational temperatures F02M 1/00) Other details of idling devices (fighting ice-formation by heating idling ports F02M 15/02) Valves responsive to engine conditions, e.g. manifold vacuum (F02M 1/00, F02M 5/00-F02M 33/00 take precedence)
