  2. Manifold vacuum - Wikipedia

    en.wikipedia.org/wiki/Manifold_vacuum

    Manifold vacuum, or engine vacuum in a petrol engine is the difference in air pressure between the engine's intake manifold and Earth's atmosphere. Manifold vacuum is an effect of a piston's movement on the induction stroke and the airflow through a throttle in the intake manifold of an engine. It is a measure of the amount of restriction of ...

  3. Crankcase ventilation system - Wikipedia

    en.wikipedia.org/wiki/Crankcase_ventilation_system

    The intake manifold vacuum, with wide open throttle, is lower in these conditions, which causes the PCV valve to open and the crankcase gases flow to the intake system. [13] The greater flow rate of intake air during these conditions means that a greater quantity of blow-by gases can be added to the intake system without compromising the ...

  4. Manifold (fluid mechanics) - Wikipedia

    en.wikipedia.org/wiki/Manifold_(fluid_mechanics)

    Hydraulic manifold A component used to regulate fluid flow in a hydraulic system, thus controlling the transfer of power between actuators and pumps Inlet manifold (or "intake manifold") An engine part that supplies the air or fuel/air mixture to the cylinders Scuba manifold In a scuba set, connects two or more diving cylinders Vacuum gas manifold

  5. Vacuum modulator - Wikipedia

    en.wikipedia.org/wiki/Vacuum_modulator

    Vacuum Modulator is an engine load sensing device that converts engine vacuum into a transmission valve body input.. Most vacuum modulators operate with manifold vacuum (below throttle blades) that offer more vacuum at idle, and proportionately changes (rises and falls) with engine load as opposed to operating on engine speed.

  6. Ignition timing - Wikipedia

    en.wikipedia.org/wiki/Ignition_timing

    Some vacuum advance units have two vacuum connections, one at each side of the actuator membrane, connected to both manifold vacuum and ported vacuum. These units will both advance and retard the ignition timing. On some vehicles, a temperature sensing switch will apply manifold vacuum to the vacuum advance system when the engine is hot or cold ...

  7. Jetronic - Wikipedia

    en.wikipedia.org/wiki/Jetronic

    Inlet manifold vacuum is measured using a pressure sensor located in, or connected to the intake manifold, in order to calculate the duration of fuel injection pulses. Originally, this system was called Jetronic, but the name D-Jetronic was later created as a retronym to distinguish it from subsequent Jetronic iterations.

  9. Secondary air injection - Wikipedia

    en.wikipedia.org/wiki/Secondary_air_injection

    To prevent the startling and potentially damaging effects of the explosive combustion of this raw fuel, a diverter valve is used. This valve senses the sharp increase in the intake manifold vacuum resulting from the sudden closure of the throttle, and diverts the air pump's outlet to atmosphere. Usually this diverted air is routed to the engine ...
