Regulates supply pressure to engine Delivery pressure and temperature logged Suitable for gasoline & diesel fuel supplies Overview Each Fuel Pressure Regulation Unit is designed to allow a range of settable fuel delivery pressures to be achieved. The pressure setpoint inputted by the customer (either directly entered into CADET V14, or client host system) is controlled by an electro pneumatically actuated regulator valve and a pressure transducer to provide pressure feedback. A PRT probe is also integrated to provide fuel temperature feedback. A pump on the inlet is used to provide flow and to increase the fuel pressure, prior to regulation. An integral manual selector can bypass the fuel pressure regulator hardware when not required. When bypassed, fuel pressure and temperature readings will still be taken. System Description The regulator consists of a constant flow automotive fuel pump. The fuel flows from the pump to the manifold block which is used to mount the pressure and temperature sensors. The constant flow rate from the pump is typically greater than the engine consumption. This over supply of fuel results in an increase in pressure seen at the regulator. When the resultant pressure is achieved the excess fuel is by-passed through the regulator to the fuel meter return line. Adjustment of the fuel pressure is achieved by way of an Electro Pneumatic Air Pressure fitting. This allows an E/P device to control the air pressure acting on the regulator diaphragm. Any spill back fuel from the engine is fed back into the pressure control unit, and is then fed to the fuel meter return line.
