Restriction of number of turns

Our engines maintain high enough frequencies of turns. Valves are set in motion by means of тарелочных the pushers directly located over distributive () by shaft (ами). Thus in movement insignificant weights of metal that does not represent danger to a drive of valves are resulted.

This restriction is partial function of injection which at too high frequency of rotation of the engine stops the further increase of turns by a fuel stopping delivery. If you will be surprised with faults in engine work on high turns, it not defect, and the built in self-defence of the engine. Border of number of turns in Audi for various engines the different:

  • Four-cylinder двухклапанный the engine: 6500 rpm.
  • Four-cylinder пятиклапанный the engine: 6800 rpm.
  • The six-cylinder engine: 6200 rpm.
