The fuel pump with an electric drive and the fuel level sensor are established in a tank. The pump takes away gasoline from a tank and via the filter submits fuel on the feeding pipeline to a pressure regulator. The fuel pump creates in system избыточ aching the pressure exceeding target pressure of a regulator and working pressure of fuel nozzles. The regulator of pressure is established on the distributive pipeline and supports pressure of fuel at the set level. The excessive amount of fuel merges in a tank on the separate pipeline. At inclusion of ignition of EBU turns on the relay of the fuel pump for 2 seconds. For this period the pump manages to lift pressure in fuel system. If within two seconds the starter was not included, EBU switches off the fuel pump. At the subsequent inclusion of a starter the fuel pump turns on repeatedly. Failure of the pump does engine start impossible. If the pump does not provide nominal pressure of fuel, it can lead to violations of normal operation of the engine. |
