3.6. The car moves jerky
With reference to the car jerk is a short-term spontaneous change of frequency of rotation of a cranked shaft of the engine irrespective of position of a pedal of "gas". In daily operation series of jerks, as a rule, take place. A limiting case of jerk — a failure — notable delay of response of the engine on pressing of a pedal of an accelerator.
It is conditionally possible to allocate three kinds of jerks:
– At the moment of a start of motion;
– At dispersal;
– At the established movement, i.e. at constant position of a pedal of "gas".
For definition of the reasons of jerks at movement of the car with инжекторным the engine the special diagnostic equipment is required, therefore we recommend to address in the service specialising on repair of systems of injection of fuel. However, as practice shows, in most cases jerks happen are caused by insufficient pressure of fuel in a fuel stage or malfunction of the gauge of position throttle заслонки.
In the presence of some skills the reason of jerks can be defined independently.
