摘要:
A control device for a high-pressure fuel pump for an internal combustion engine having a solenoid valve installed as a suction valve in a fuel charging passage to a pressurized chamber. A pump suction pressure generated in the pressurized chamber in the charging stroke is exerted on the solenoid valve in a valve opening direction. The solenoid valve is closed at OFF state of an electric driving signal and opened at ON state of the electric driving signal, so that a discharging rate of the high-pressure fuel pump of variable discharge rate type is controlled by an opening and closing control of the solenoid valve.

A heat exchanger comprises a first plate and a second plate. A coolant flow passage is formed by brazing the first plate and the second plate by use of a first brazing filler metal. A pipe is brazed between a first groove portion provided in the first plate and a second groove portion provided in the second plate by use of a second brazing filler metal. A pair of first flanges provided contiguously with the first groove portion. Each of the first flanges includes an inner surface. A pair of second flanges provided contiguously with the second groove portion. Each of the second flanges includes an inner surface. At least one of the inner surfaces of the first flanges and the inner surfaces of the second flanges is covered with the second brazing filler metal. The first and second flanges are held by jigs upon brazing of the pipe.

A display device includes: a plurality of display interconnects (3) provided so as to extend parallel to each other; a drive circuit (44aa) provided at one ends of the display interconnects (3), and connected to the display interconnects (3); a first interconnect (Wa) provided so as to cross the other ends of the display interconnects (3) in an insulating state; and a second interconnect (Wb) provided so as to cross the one ends of the display interconnects (3) in an insulating state, and so as to be connected to the first interconnect (Wa). When any of the display interconnects (3) is disconnected, a display signal from the drive circuit (44aa) is supplied to the other side of the disconnected display interconnect (3) sequentially through the second interconnect (Wb) and the first interconnect (Wa) in this order via an amplifier circuit (A). The second interconnect (Wb) is configured so that the display signal from the drive circuit (44aa) is supplied to the first interconnect (Wa) via a plurality of paths (Pa, Pb) that are different from each other.

摘要:
A high-pressure fuel pump of an internal combustion engine has a fuel injection valve provided on a cylinder. The high-pressure fuel pump is for pumping fuel to the fuel injection valve, and has a pressure chamber, a plunger for pressurizing the fuel in the pressure chamber, a fuel valve provided in the pressure chamber, and an actuator for operating the fuel valve. A control device has means for calculating the drive signal of the actuator so as to realize the variable discharge of the high-pressure fuel pump. The end timing of the drive signal is limited or restricted so that an attraction force of a solenoid coil is not maintained at the bottom dead center of the plunger in case that the required discharge to the fuel pump is less than the total discharge.

An apparatus controls the quantity of fuel injection of an injector in accordance with the fuel pressure in the fuel rail of a direct injection type internal combustion engine. A reference value for controlling the injector is obtained on the basis of the difference and the fuel pressure in the fuel rail at the time of starting fuel injection out of injector.

There is provided a high-pressure fuel pump drive circuit for manipulating the electric current to be passed to a solenoid coil for controlling a high-pressure pump. This circuit is characterized in that a first switching element, the solenoid coil and a second switching element are connected in series with each other in a rout from a source voltage side to the ground side, that a flywheel diode for passing electric current to a power source is disposed parallel with the solenoid and with the first switching element, and that a Zener diode connected with the power source is disposed parallel with the second switching element, wherein a counter electromotive force to be developed at the opposite ends of solenoid coil on the occasion when the second switching element is changed from ON to OFF is consumed by the flywheel diode provided that the first switching element is in a state of ON, and the counter electromotive force is more rapidly consumed by the Zener diode provided that the first switching element is turned OFF.
