The regulator of pressure of fuel includes редукционный the valve with a press spring and диафрагменным a sensitive element, fig. the Regulator of pressure of fuel. The diaphragm divides two cavities of a regulator: fuel and vacuum. The vacuum cavity is connected by the pipeline to an inlet collector of the engine. In a vacuum cavity the press spring of a regulator is located also. Regulator function is maintenance of the set stable pressure of the fuel arriving to atomizers, and updating of this pressure depending on engine loading. At reduction разряжения in an inlet collector, pressure of fuel in system increases. The regulator of pressure of fuel is established on the end of the distributive pipeline and is not subject to repair in operation. At the working engine the regulator supports pressure of fuel in system in a range 284–225 кПа.
If pressure leaves for the bottom border, normal work двигате ля is broken and ЭБУ establishes a code of malfunction 44. At an elevated pressure of fuel more than 325 кПа there is a strong smell of the fulfilled gases and the code of malfunction 45 is established. |
