The regulator of pressure of fuel includes the reduktsionny valve with a press spring and a diafragmenny sensitive element, fig. 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 also press spring of a regulator is located. Function of a regulator is maintenance of the set stable pressure of the fuel arriving to nozzles, and correction of this pressure depending on engine loading. At razryazheniye reduction 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 of 284-225 kPas.
If pressure leaves for the bottom border, normal work двигате ля is broken and EBU establishes a code of malfunction 44. At a fuel elevated pressure more than 325 kPas appear a strong smell of the fulfilled gases and the code of malfunction 45 is established. |
