7.3. Check of frequency of rotation at idling

Frequency of rotation at idling, depending on the included consumer (for example, headlights, the conditioner or the amplifier of the steering mechanism), is constantly corrected by the block of management of the engine. Carburettor engines work thus on 700 rpm, turbodiesels can rotate the cranked shaft at level of 900 rpm. For check it is necessary to have a tachometre, in workshops for this purpose connect the motor-tester. If the measured values do not correspond to factory parametres malfunction cannot be eliminated separately: experts then check all control system of the engine. Then it is necessary for onboard computer to "pass" pair of kilometres that to recycle. On such to "a training phase high fluctuations at idling – quite normal phenomenon.
