3.6.1. Jerk at the moment of a start of motion

At the moment of a start of motion the limiting case of jerk — a failure is more often takes place. The most unpleasant sensations are connected with delay of response of the engine on pressing of a pedal of "gas". Sometimes the engine thus even глохнет.

Jerk arises at the moment of the beginning of opening throttle заслонки when on a signal of the gauge of position throttle заслонки ECU defines the moment of transition from an idling mode on a loading mode and should increase quantity of fuel submitted through atomizers. At insufficient pressure in a fuel stage, even at increase in duration of injection, fuel for smooth трогания from a place does not suffice. A technique of check of pressure of fuel Check of pressure of fuel in the power supply system see in subsection.
