What Is Ported Vacuum at Lucy Haire blog

What Is Ported Vacuum. Ported vacuum was the same amount of vacuum at 1,000 rpm as it was at 2,500 rpm. In modern cars with computerized engine controllers, all those sensors and the controller change both mixture and spark timing 50 to 100 times per second, and we don't even have a distributor. The vacuum port acts as a source of vacuum pressure, needed by a vacuum advance mechanism to adjust the ignition timing accordingly. When it comes to automotive ignition systems, the type of vacuum you rely on can significantly affect engine performance. Vacuum that increases as engine speed increases. All engines use vacuum in some capacity. On older vehicles the carburetors were often designed with different vacuum ports to. As the pedal is pushed, the vacuum increases. Venturi vacuum was used before distributors had mechanical advance as it was a increasing vacuum signal as the engine ran faster and faster. Which to use & when !!! This mechanism uses the strength. With that thought in mind consider if the distributor hooked to ported vac, as air speed increases the ported vac activates and.
