摘要： In apparatus for injecting fuel into an internal combustion engine, a flip-flop used for frequency dividing an engine rotational angle signal is arranged to be reset when a basic injection pulse is not coincident with a cylinder-determining pulse signal. The basic injection pulse is produced by a Q/N charge-discharge circuit arranged to start charging a capacitor in response to a leading edge of an output pulse from the flip-flop and to start discharging the same in response to a trailing edge of the same where time constant on charging is constant and time constant on discharging is variable depending on the quantity Q of intake air of the engine. The basic injection pulse is used to produce final injection pulse with which fuel injection valves are operated where the width of the basic injection pulse determines the basic amount of fuel to be injected. After the flip-flop is reset, its output pulse is shifted by 180.degree. CA, and thus the basic injection pulse TP occurs just before the final injection pulse thereby the latest engine operating conditions are reflected on the amount of fuel to be injected.

摘要： A residual fuel quantity measuring device for automobiles has a fuel flow rate sensor provided in a filler neck of a fuel tank for measuring the flow rate of liquid fuel supplied to a fuel tank. A computer computes the quantity of liquid fuel remaining in the fuel tank from a previously stored residual quantity of liquid fuel, the measured fuel flow rate, the injection rate of fuel from fuel injection valves, and the purge quantity of fuel evaporated in the fuel tank. A fuel meter visually displays the thus computed residual quantity of liquid fuel in the fuel tank.

摘要： An antidissipation apparatus for evaporated fuel vapor for an internal combustion engine. A purge passage connects the intake manifold and the fuel tank. A canister is installed in the purge passage and adsorbs evaporated fuel vapor generated in the fuel tank. A purge pump is installed in the purge passage and delivers the adsorbed evaporated fuel vapor to the intake manifold. Since the purge pump is driven by at least a part of a fuel flow in the fuel passage, the purge pump can change its discharge amount of the adsorbed evaporated fuel vapor to the intake manifold according to an amount of the fuel flow in the fuel passage. Therefore, the evaporated fuel vapor which is adsorbed at the canister can be supplied (purged) to the intake manifold by the purge pump forcibly even if the engine is a lean-burn type which can not employ large negative pressure of the intake manifold.

摘要： A motor includes a rotor, a commutator, a brush, and a bias member. The commutator has a rectifying surface. The commutator rectifies an electric current supplied to the rotor through the rectifying surface. The rotor is rotated by being supplied with the electric current. The brush makes contact with the commutator via the rectifying surface. The rotor is supplied with the electric current through the brush. The brush starts making contact with the commutator on an entry side of the brush as the rotor and the commutator rotate with respect to the brush along a rotative direction and the commutator intermittently makes contact with the brush. The bias member biases the brush toward the entry side.

摘要： The present invention provides a regenerative pump for supplying fuel into an injection device for an internal combustion engine. The regenerative pump has a longer pressurizing passage and a slanted discharge port connected thereto and formed at an outer periphery thereof. The pressure loss in the pump is small because the fuel flows smoothly into the discharge port from the pressurizing passage, and accordingly the efficiency of the pump is high and the pump can be made small in size at the same time.

摘要： An improved fuel injection control apparatus, in which a reference pressure is provided to a pressure regulator, for simplifying the fuel supply system by preventing the fuel quantity injected from injection valves into an engine from being influenced by variations in the air intake pressure. A pressure regulating device disposed in a fuel supply pipe between a fuel pump and the fuel injection valve regulates the pressure of fuel supplied from the fuel pump to the fuel injection valve so that the pressure is proportional to the predetermined pressure, without returning fuel from the injection valve to the fuel tank. An intake pressure detecting device detects the pressure in the intake pipe, and a fuel injection quantity correcting device corrects the fuel injection quantity according to deviations of the fuel pressure regulated by the pressure regulating device from a proper value due to the differential pressure between the pre-determined pressure of the pressure regulating means and the intake pressure. Accordingly, he fuel injection quantity injected from the injection valve is corrected based on the operating condition of the engine due to the variation of the intake pressure. As a result, the fuel supply system is simplified.

摘要： A fuel supply device includes a relief valve, a pressure regulator, and a controller. The controller controls a first pump to send fuel into an engine through a first passage, and controls a second pump to send fuel into a second passage to communicate with the first passage. The relief valve discharges fuel from the second passage when a fuel pressure of the second passage is higher than a relief pressure. The pressure regulator discharges fuel when a fuel pressure of fuel chamber is higher than a regulation pressure higher than the relief pressure in a state that a fuel pressure of backpressure chamber is equal to the relief pressure.
