摘要： An intermittent swirl type injection valve having a spray angle, capacity coefficient and fuel spray travel distance set so that the valve produces optimum engine operating conditions, with the spray angle, capacity coefficient and fuel spray travel distances being determined taking into account the gap area A.sub.c, the spray hole diameter d.sub.e, and the area A.sub.g of tangential passages in the valve. The injection valve includes a valve body and a valve needle slidably fitted in a valve hole formed in the valve body. A spray hole in the valve body merges with a valve seat provided at an end of the valve hole, and the spray hole is shaped to receive the lower end of the valve needle. Tangential passages swirl the fuel when the needle valve leaves the valve seat to open the valve to spray fuel substantially conically through the spray hole. The injection valve is designed so as to satisfy the following conditions:.alpha.=20.degree. to 75.degree.,d.sub.e =0.3 to 1.2 mm,and ##EQU1## where .alpha. is the spray angle of the fuel and .theta. is the angle between the central axis of the tangential passages and the central axis of the valve needle.

摘要： A spill type swirl injector includes a nozzle body, an injection port, a pressurized fluid induction passage, a valve assembly, a swirl chamber, two tangential pressurized fluid supply passages and a spill assembly including two spill openings provided on an outer cylindrical wall of a movable member of the valve assembly and opened to inner side of the swirl chamber. An axial hole provided in the movable member of the valve assembly and in the nozzle body and discharge passage assembly is connected to a pressurized fluid supply source, thereby spilling a predetermined quantity of the pressurized fluid from the inner side of the swirl chamber through the spill opening, axial hole and spill passage assembly. The spill type swirl injector immediately injects the fluid in the form of a liquid film flow having a sufficiently high swirling velocity, after the valve is opened, so that the sprayed liquid droplets are remarkably fine and uniform and the atomizing characteristics and response of the atomization to the injection pressure are improved in comparison with prior spill type swirl injectors.

摘要： A pressure boosting unit (110) is provided in each fuel injection valve of an engine (1). A pressure of fuel to be supplied to the fuel injection valve from a common rail (3) is boosted as required. An ECU (20) causes low pressure injection to be performed with the pressure boosting unit 110 being in a non-operated state, and high pressure injection to be performed with the pressure boosting unit (110) being in an operated state, and the pressure of the fuel being maintained at a boosted pressure. Based on the result, the ECU (20) corrects a fuel injection period of the fuel injection valve. Also, after the correction of the fuel injection period is completed, fuel injection is performed before the pressure of the fuel reaches the boosted pressure after the pressure boosting unit starts to be operated. Based on the result, operation starting timing of the pressure boosting unit is adjusted.

A slit-shaped nozzle outlet 4 is constructed such that its transverse walls from its inner end 9 to its outer end 10 have an included angle .gamma. of 20 to 180 degrees, such that an angle .beta. of 0 to 90 degrees is made between the axis of the fuel injector and the opening direction of the slit-shaped nozzle outlet 4, such that the nozzle outlet 4 is diverged outward from a plane joining the axis to the fuel injector and the inner end 9, and such that the opposite portions of the inner end 9 have a width W of 0.05 mm to 0.24 mm. By combining these constructions suitably, the fuel spray can be formed efficiently and properly into a flat sector shape thereby to improve the fuel injection characteristics.
