3.6. The car moves breakthroughs
With reference to the car breakthrough — this short-term spontaneous change of frequency of rotation of a cranked shaft of the engine irrespective of the provision of a pedal of "gas". In daily operation series of breakthroughs, as a rule, take place. A limiting case of breakthrough — a failure — notable delay of response of the engine on pressing of a pedal of an accelerator.
It is conditionally possible to allocate three types of breakthroughs:
– at the moment of a start of motion;
– at dispersal;
– at the established movement, i.e. at the continuous provision of a pedal of "gas".
For definition of the reasons of breakthroughs at car movement with the injector engine the special diagnostic equipment therefore we recommend to address in the car-care center specializing on repair of systems of injection of fuel is required. However, as practice shows, in most cases breakthroughs happen are caused by insufficient pressure of fuel in a fuel stage or malfunction of the sensor of provision of a butterfly valve.
In the presence of some skills it is possible to define the reason of breakthroughs independently.
