    • PROBLEM TO BE SOLVED: To obtain a layout structure of a fuel system which prevents the migration of lubricating oil at the time of a fall in a small and lightweight portable engine generator.SOLUTION: The portable engine generator is provided with a power generation part 40 which generates power by operating an engine 30, and a negative pressure fuel cock 10 for supplying fuel to the engine 30 by utilizing a negative pressure of a crank chamber 31 of the engine 30 as an operation negative pressure. The negative pressure fuel cock 10 is arranged in the side opposite to a negative pressure take-out port 39 of the crank chamber 31 to the position of the power generation part 40 at the time of the fall of the portable engine generator, and in a position higher than that of the negative pressure take-out port 39 at the time of the upright stand of the portable engine generator. The negative pressure fuel cock 10 is arranged between a cooling air intake port 43 of the engine 30 and a louver 8 for taking in the cooling air provided in an external cover 2 of the portable engine generator.
    • 要解决的问题:获得在小而轻便的便携式发动机发电机中防止润滑油迁移的燃料系统的布局结构。解决方案:便携式发动机发电机设置有发电部分40 通过利用发动机30的曲轴室31的负压作为运转负压,向发动机30供给燃料的负压燃料旋塞10产生发动机30的动力。 在便携式发动机发生器的坠落时,负压燃料旋塞10布置在与曲轴室31的负压取出口39相对的一侧到发电部40的位置,并且在 位置高于便携式发动机发动机立柱时的负压取出口39的位置。 负压燃料旋塞10布置在发动机30的冷却空气进气口43和用于吸入设置在便携式发动机的外部盖2中的冷却空气中的通风板8之间。

    • PROBLEM TO BE SOLVED: To maintain optimal air excess ratio to enable stable combustion when gas containing methane is used as fuel for a gas engine for power generation.SOLUTION: A gas engine 10 includes a power generator 16 that is connected to an output shaft, an air intake path 18 through which gas containing methane of dilute concentration for air conditioning (ventilation air methane [VAM] gas) discharged from a coal mine is supplied, and gas mixing parts 54a-54d that mixes gas containing methane of high-concentration (coal mine methane [CMM] gas) midway of the air intake path 18. The gas engine 10 mixes the gas containing methane of dilute concentration and the gas containing methane of high concentration, supplies the mixed gas to a combustion chamber, and burn the mixed gas. In the gas engine 10, mixture ratio adjusting devices 26 and 28 are provided in the air intake path 18 on the upstream side of a supercharger 30 provided on the air intake path 18 on the upstream side of the gas mixing parts 54a-54d. The mixture ratio adjusting devices 26 and 28 adjust the mixture ratio of the gas containing methane of dilute concentration and atmospheric air. An air intake controlling means 90A controls the temperature or flow rate of intake air flowing into the supercharger 30 such as to be within a fixed range.
    • 要解决的问题:为了保持最佳的空气过剩率,当使用含有甲烷的气体作为用于发电的燃气发动机的燃料时,能够稳定地燃烧。 解决方案:燃气发动机10包括连接到输出轴的发电机16,进气通道18,通过该进气通道18从空气排出的空气(通风空气甲烷[VAM]气体) 提供煤矿,以及混合气体混合部件54a-54d,其将进入通道18中间的高浓度甲烷气体(煤矿甲烷[CMM]气体))混合。气体发动机10混合含有浓度浓度的甲烷的气体 并且含有高浓度甲烷的气体将混合气体供给到燃烧室,并燃烧混合气体。 在燃气发动机10中,混合比调节装置26和28设置在设置在气体混合部54a-54d的上游侧的进气通道18上的增压器30的上游侧的进气通路18中。 混合比调节装置26和28调节含有浓度浓度的甲烷和大气的气体的混合比。 进气控制装置90A控制流入增压器30的进气的温度或流量在一定范围内。 版权所有(C)2012,JPO&INPIT
