摘要： PROBLEM TO BE SOLVED: To reduce a capacity of a pump for supplying fuel in a fuel injection valve in which a displacement enlargement rate is varied when a nozzle needle is lifted.
SOLUTION: An outer needle stopper 3 is slidably attached to the outer periphery of the nozzle needle 12 on the opposite side to an injection hole. When a piezoelectric piston 6 is driven by a piezoelectric actuator so that the pressures of displacement enlarging chambers 222, 232 are increased, the nozzle needle 12 and the outer needle stopper 3 receive the pressures and the nozzle needle 12 is urged in a valve opening direction. When an amount of lift of the nozzle needle 12 reaches a predetermined lift amount, the movement of the outer needle stopper 3 is restricted by a stopper 236 so that the displacement enlargement rate is varied. Further, since a high pressure part is connected to a low pressure part via a sliding part through only one path extending from the displacement enlarging chamber 222 via the outer peripheral side of the piezoelectric piston 6 to the low pressure part, a fuel leak amount to the low pressure part is decreased to thereby reduce the capacity of the fuel supplying pump.

摘要翻译：解决的问题：为了降低在喷嘴针被提升时位移增大率变化的燃料喷射阀中供给燃料的泵的容量。解决方案：外针止动器3可滑动地附接到喷嘴针12的与喷射孔相反的一侧的外周。当压电活塞6由压电致动器驱动使得位移扩大室222,232的压力增加时，喷嘴针12和外针止动件3受到压力，并且喷嘴针12被推压在阀打开方向。当喷嘴针12的提升量达到预定的提升量时，外针止动器3的移动被止动件236限制，从而使位移增大率变化。此外，由于高压部分经由滑动部分经由位移扩大室222经由压电活塞6的外周侧延伸到低压部分的一个路径连接到低压部分，所以燃料泄漏量为低压部分减小，从而降低燃料供应泵的容量。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To enable fuel injection of a minute quantity with high accuracy by inhibiting fluctuation of a lift amount of a valve element 16 when injecting fuel of the minute quantity by a piezo type injector 1. SOLUTION: A piezoelectric actuator 18 of the injector 1 is divided into a first application section 45 which is formed of parts of a plurality of piezoelectric members 17 and can be separately applied with electric voltage, and a second application section 46 which is formed of the piezoelectric members 17 other than those included in the first application section 45. Electric voltage can be applied solely to the first application section 45 to generate driving force and an extension amount. Sensitivity of the lift amount of the valve element 16 with respect to the applied electric voltage can be therefore increased. Consequently, operation of the lift amount by adjustment of applied electric voltage is facilitated. Thus when the fuel of a minute quantity is injected by the piezo type injector 1, the fuel injection of the minute quantity can be highly accurately performed with fluctuation of the lift amount of the valve element 16 inhibited.

摘要翻译：要解决的问题：通过压电型喷射器1喷射微量燃料时，通过抑制阀元件16的提升量的波动，以高精度实现微量燃料喷射。解决方案：喷射器1的压电致动器18分为第一施加部45，第一施加部45由多个压电构件17的一部分形成，并且可以分别施加电压;以及第二施加部46，其由压电构件除了第一应用部分45中包括的那些之外，电压可以单独施加到第一施加部45以产生驱动力和延伸量。因此，阀元件16的提升量相对于所施加的电压的灵敏度可以增加。因此，通过调整施加的电压来提高升力量的操作变得容易。因此，当通过压电型喷射器1喷射微量的燃料时，可以通过抑制阀元件16的升程量的波动来高精度地进行微量的燃料喷射。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a variable injection hole injector capable of miniaturizing a piezoelectric actuator. SOLUTION: The injector 2 is provided with a first valve unit which consists of a first needle 21, a first intermediate piston 23 and a first upper piston 25 and a second valve unit which consists of a second needle 22, a second intermediate piston 24 and a second upper piston 26. The first and second valve units are driven by hydraulic pressure applied to a first control chamber 36 below the first intermediate piston 23, and an upper side of the first intermediate piston is provided in a first low pressure chamber 37. Consequently, set load of the piezoelectric actuator 51 can be reduced. Also, since total section area of the first and second pistons which high pressure is applied on is set smaller than total section area of the first and second needles 21, 22, valve opening force acting on the first and second valve units at a time of valve open is suppressed and drive hydraulic pressure at the time of lifting can be reduced and the piezoelectric actuator 51 can be miniaturized.

SOLUTION: The accumulation amount estimation device comprises: a filter disposed on an engine exhaust passage to carry a catalyst; an accumulation amount estimation means detecting differential pressure between before and after the filter and estimating the amount of soot accumulated on the filter based on the detected differential pressure; an oxidation state detection means detecting an oxidation state of the soot accumulated on the filter; and a forced oxidation means increasing a filter temperature to be a soot oxidation temperature or more to forcibly oxidize the soot accumulated on the filter near the catalyst carried by the filter. When oxidation state detection means detects that the soot accumulated on the filter near the catalyst is partially oxidized, the accumulation amount estimation means estimates the soot accumulation amount after the forced oxidation means oxidizes the soot accumulated on the filter near the catalyst.

摘要： PROBLEM TO BE SOLVED: To provide a normal close type high pressure pump having improved responsiveness at high speed rotation. SOLUTION: In the normal close type high pressure pump, a needle 61 installed integrally with a movable core 53 abuts against a valve member 21 by biasing force of a needle spring 56 when an electromagnetic actuator 50 is not energized and advances by electromagnetic attraction force upon energization. The needle 61 has a flange portion 611 having the outer diameter slightly smaller than the inner diameter of a valve cylindrical part 232. When the pressure in a pressurization chamber 95 is reduced and the valve member 21 is opened in a suction process at high speed rotation, fuel flows through a throttle flow passage 931 in a gap between the flange portion 611 and the valve cylindrical part 232 to generate a differential pressure, and the advancing operation of the needle 61 is assisted by the differential pressure. With this, the valve member 21 can be opened surely and the responsiveness at high speed rotation is improved. COPYRIGHT: (C)2011,JPO&INPIT
