F02M 7/133

Auxiliary jets, i.e. operating only under certain conditions, e.g. full power (means for enriching charge at high combustion-air flow F02M7/04; means for enriching charge on sudden throttle opening, i.e. at acceleration F02M7/06)

Introduced: January 1990

Title

Titles differ between systems:

IPC: Auxiliary jets, i.e. operating only under certain conditions, e.g. full power

CPC: Auxiliary jets, i.e. operating only under certain conditions, e.g. full power (means for enriching charge at high combustion-air flow F02M7/04; means for enriching charge on sudden throttle opening, i.e. at acceleration F02M7/06)

Full Title

Full titles differ between systems:

IPC:

Carburettors with means for influencing, e.g. enriching or keeping constant, fuel/air ratio of charge under varying conditions > Other installations, with moving parts, for influencing fuel/air ratio, e.g. having valves > Auxiliary jets, i.e. operating only under certain conditions, e.g. full power

CPC:

Carburettors with means for influencing, e.g. enriching or keeping constant, fuel/air ratio of charge under varying conditions (choke valves for starting F02M1/00) > Other installations, with moving parts, for influencing fuel/air ratio, e.g. having valves (F02M7/24 takes precedence) > Auxiliary jets, i.e. operating only under certain conditions, e.g. full power (means for enriching charge at high combustion-air flow F02M7/04; means for enriching charge on sudden throttle opening, i.e. at acceleration F02M7/06)
