摘要： An altitude compensated vacuum control system for regulating the vacuum servo mechanism of an internal combustion engine of the type having a distributor with a vacuum servo controlled advance mechanism incorporating a positive stop for maximum spark advance, a carburetor to provide a source of vacuum to operate said vacuum servo mechanism and a vacuum control valve assembly for regulating the vacuum servo mechanism of said distributor. The vacuum control valve assembly receives a spark port vacuum signal from the carburetor to maintain a predetermined vacuum spark advance as the engine begins to accelerate. Upon attaining the predetermined vacuum spark advance and at a given speed, the control assembly becomes operative to sum the initial first predetermined level vacuum signal to a secondary altitude compensated vacuum source signal, which is a function of an engine operating parameter, thereby causing the vacuum servo spark advance mechanism in the distributor to obtain a maximum spark advance by moving to a positive stop within the distributor. This full vacuum advance is maintained independent of the degradation of the vacuum signals as a result of changes in altitude, provided the spark port signal is greater than the full vacuum spark advance signal.
