FUEL PRESSURE CONTROL DEVICE-BASED HFATING SYSTEM

摘要

A temperature control based fuel pressure control device is provided to compensate temperature drop resulting from pressure reduction quickly by regulating the electric heating wire. A temperature control based fuel pressure control device comprises a fuel supply unit(110), a fuel pressure control unit(140), a fuel discharge unit(160), a temperature sensing unit(120), an electronic control unit(130), and a heat source supply unit(150). The fuel supply unit supplies high pressure fuel. The fuel pressure control unit reduces the pressure of the high pressure fuel to the critical value. The fuel discharge unit discharges low pressure fuel formed by the pressure reduction to a vehicle engine. The temperature sensing unit senses the temperature lowered by the pressure reduction or external temperature. The electronic control unit generates control signal for changing the lowered temperature to the set operation temperature. The heat source supply unit supplies heat source corresponding to the control signal to obtain the set operation temperature through electric heating wire mounted on the fuel pressure control unit.
