Air System

The intake manifolds, connected to an take air distributor, supply each cylinder with air. A pressure switch, pressure sensor and ignition distributor are also connected to intake air distributor. Pressure switch operates according to difference in pressure in intake air distributor and atmospheric pressure, while pressure sensor measures actual pressure in intake air distributor. A throttle valve, operated by accelerator pedal, is located at the mouth of the intake air distributor. Intake air distributor is connected to air cleaner by a rubber elbow. Idling air system, is in the form of a by-pass system, in intake air distributor, it joins behind throttle valve. Its functional cross section, can be varied, with an idling air adjusting screw. An auxiliary air line, from air cleaner via auxiliary air regulator, to intake air distributor forms the warming-up air system. Its volume is varied, depending on engine temperature, by the auxiliary air regulator.
