摘要:
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.

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.
