    • PROBLEM TO BE SOLVED: To provide a fuel (such as gas oil) lubricating diesel engine without making a lubricating pump and an injection pump influence with each other, by reducing the number of part items.
      SOLUTION: This fuel (such as gas oil) lubricating diesel engine 1 has a fuel supply passage 4 for supplying fuel to an oil pan 3 from a fuel tank 2 by an electric supply pump 6, a lubricating system fuel supply passage 8 for supplying the fuel to engine respective parts 7 from the oil pan 3 by the lubricating pump 10, and an injection system fuel supply passage 13 for supplying the fuel to an injection system 12 from the oil pan 3 by the injection pump 15. Since the lubricating system fuel supply passage 8 and the injection system fuel supply passage 13 are independently formed, these do not have influence on each other, and desired lubrication performance and injection performance can be provided.

    • 要解决的问题:通过减少零件的数量来提供不使润滑泵和喷射泵相互影响的燃料(例如瓦斯油)润滑柴油发动机。 解决方案:该燃料(例如瓦斯油)润滑柴油发动机1具有燃料供给通道4,用于通过供电泵6将燃料从燃料箱2供给到油底壳3,润滑系统燃料供给通道8 用于通过润滑泵10从油底壳3向发动机各部分7供应燃料;以及喷射系统燃料供给通道13,用于通过喷射泵15从油底壳3向喷射系统12供应燃料。由于 润滑系统燃料供给通道8和喷射系统燃料供给通道13独立地形成,这些不会相互影响,并且可以提供期望的润滑性能和喷射性能。 版权所有(C)2006,JPO&NCIPI

    • PROBLEM TO BE SOLVED: To provide a fuel injection device capable of dissolving wax-clogging of a filter.SOLUTION: The fuel injection device 1 includes a high-pressure pipe 20 for guiding high-pressure fuel flowing out of a common rail 4 by opening a decompression valve 13 to a filter 6 as a circulation flow passage for introducing a part of the high-pressure fuel from a high-pressure flow passage from a fuel supply pump 3 to an injector 5 into the filter 6. The decompression valve 13 functions as an introduction valve for introducing the high-pressure fuel into the circulation flow passage. The high-pressure 20 includes a check valve 25 and a circulation flow valve 26 from the upstream side. Thereby, valve-opening pressure of the check valve 25 is set comparatively high, and thereby the fuel in the high-pressure pipe 20 can be introduced into the filter 6 while keeping the pressure thereof at a high value. Thereby, the fuel can be introduced into the filter 6 in a further high-temperature condition, whereby wax-clogging can be surely dissolved.
    • 要解决的问题:提供一种能够溶解过滤器蜡堵塞的燃料喷射装置。 解决方案:燃料喷射装置1包括用于引导从共轨4流出的高压燃料的高压管20,该高压管通过将减压阀13打开到过滤器6,作为循环流动通道,用于引入一部分 从燃料供给泵3到喷射器5的高压流路的高压燃料进入过滤器6.减压阀13用作将高压燃料引入循环流路的导入阀。 高压20包括从上游侧的止回阀25和循环流量阀26。 因此,止回阀25的开阀压力被设定得比较高,从而能够将高压管20内的燃料引入到过滤器6中同时保持其高压。 由此,能够在另外的高温条件下将燃料引入到过滤器6中,从而可以可靠地溶解蜡堵塞。 版权所有(C)2012,JPO&INPIT
