    • A fuel injection method wherein optimum fuel injection timing in a fuel-injection type gas fuel engine is determined by setting fuel injection end timing to be after the start of opening of an intake valve. That is, when injection ends in a first half of the intake valve open period the volumetric efficiency .eta.v falls and the engine output also falls, because the injection period overlaps with a period of positive pressure arising inside the intake pipe before opening of the intake valve, but when injection ends in a second half of the intake valve open period the volumetric efficiency .eta.v rises and the engine efficiency also rises, because the injection period overlaps with a period of negative pressure arising in the intake pipe during the first half of the intake value open period. Consequently, when fuel is injected during this trough in the intake port pressure, the volumetric efficiency increases and the engine output also increases by several percent.
    • 一种燃料喷射方法,其中燃料喷射型气体燃料发动机中的最佳燃料喷射正时通过将燃料喷射结束定时设定为在开阀开始之后。 也就是说,当进气阀打开期间的前半部分的喷射结束时,体积效率等级下降,并且发动机输出也下降,因为喷射周期与在进气口打开之前在进气管内部产生的正压时间重叠 但是当喷射在进气阀打开时段的后半段结束时,容积效率η升高并且发动机效率也上升,因为喷射周期与进气管在上半年期间产生的负压时间重叠 摄入量开放期。 因此,当在进气口压力期间在该槽内喷射燃料时,容积效率增加,发动机输出也增加了几个百分点。

    • A device for reducing air resistance of a vehicle includes a front bumper, a bumper spoiler, and a mounting piece. The bumper spoiler includes a main body section and a mounting base section which protrudes from a reverse side of the main body section. The mounting base section is made of rigid material capable of being elastically deformed and harder than the main body section. The main body section and the mounting base section are integrally joined to each other. The mounting base section has a first mounting section and a second mounting section. The first mounting section is inserted into and elastically engaged with a first mounting hole of the bumper, thereby being temporarily fixed to the bumper. The second mounting section is inserted into the second mounting hole of the bumper to be finally fixed to the bumper by the mounting piece.
    • 用于降低车辆的空气阻力的装置包括前保险杠,保险杠扰流板和安装件。 保险杠扰流器包括主体部分和从主体部分的相反侧突出的安装基部。 安装基座部分由能够弹性变形并且比主体部分更硬的刚性材料制成。 主体部和安装基部彼此一体地接合。 安装基部具有第一安装部和第二安装部。 第一安装部分插入并与缓冲器的第一安装孔弹性接合,从而临时固定在保险杠上。 第二安装部分插入保险杠的第二安装孔中,最后通过安装件固定到保险杠上。
