6.3.5. Idling regulation
Valve LFR (Leerlauffullungs-regelung) systems of regulation of filling is attached to an inlet collector and regulates air expense at work in a mode of idling bypassing throttle заслонки. Thanks to it frequency of rotation of the cranked shaft, remaining a constant irrespective of is reached, whether such consumers of energy, as the pump of the amplifier of the steering mechanism or the central air compressor are included. Management of valve LFR is carried out by the electronic block of management of system of injection. The inlet collector is executed so that soaked up air with the help заслонок goes on long or on a short way. At frequency of rotation of a cranked shaft more low about 4000 rpm заслонки are closed, soaked up air moves on a long way thereof the engine twisting moment raises. At frequency of rotation of a shaft over 4000 rpm заслонки open, soaked up air goes on a short way thanks to what capacity raises. The block of management of system of injection operates movement заслонок by means of the vacuum valve which includes мембранный the mechanism of a drive of a shaft заслонок. The system рециркуляции the fulfilled gases consists of mechanical and electric valves and serves for reduction of quantity NОx in the fulfilled gases to the catalyst. The electronic block of management is in the right niche for feet under plastic facing. The prevention
