摘要： A fuel pressure regulator for a no-return fuel system for an automotive engine with fuel injectors having a housing with a flexible diaphragm between first and second chambers. The second chamber has a fuel inlet receiving fuel from a fuel pump with a spring biased valve therein to admit fuel to the second chamber and an outlet to supply fuel to the engine. The second chamber is in continuous communication with the engine to accumulate any fuel expansion that may occur during engine deceleration or when the engine is turned off due to heating the fuel. The first chamber continuously communicates with the engine air intake manifold so that fuel is supplied to the engine fuel injectors at a substantially constant pressure drop across the injectors. An over-pressure relief by-pass valve responsive to pressure at said fuel inlet will by-pass fuel to a reservoir when pressure in said second chamber opens said spring biased valve. A switch in said by-pass valve acts through a pulse width modulator to reflect the over-pressure to the pump drive.

摘要： A fuel-supply system has a fuel pump, a pressure controller, a signal output device and a power switch. The pressure controller adjusts the observed fuel pressure of the fuel and may electronically communicate with a motor driving the fuel pump to regulate the supply of fuel from a fuel tank of the fuel-supply system to an engine. In detail, the pressure controller performs feedback control of a voltage applied to the motor such that the pressure of a fuel pumped from the fuel pump approaches to have a first target and/or ideal fuel pressure value. Further, the signal output device outputs the first target fuel pressure value to the pressure controller. Activation of the power switch supplies power, from a power source, to the pressure controller, the motor and the signal output device. Further, the pressure controller may perform feedback control based on a second target fuel pressure value.

摘要： A pressure sensor subsystem measures the pressure within a fuel pump and outputs an under-pressure signal when the measured pressure is below a predetermined threshold pressure value. A temperature sensor subsystem measures the temperature within the fuel pump and outputs an over-temperature signal when the measured temperature is above a predetermined threshold temperature value. A timing circuit monitors the pressure sensor subsystem and the temperature sensor subsystem for output of the under-pressure and over-temperature signals and outputs a pump disconnect signal when at least one of the signals is output for a prescribed time duration. A power controller disengages power from the pump upon output of a pump disconnect signal by the timing circuit.

摘要： A fuel pressure detector and a pressure accumulator are disposed in a fuel distribution line, an engine control apparatus controlling activation of a fuel pump based on output from the fuel pressure detector. The fuel pump is activated at maximum capacity to fill the fuel distribution line with fuel at a controlled pressure controlled by a fuel pressure regulator, then stopped. In this state, fuel accumulated under pressure in the pressure accumulator replenishes the fuel distribution line until fuel pressure inside the fuel distribution line drops to a predetermined value due to fuel injection by fuel injection valves.
