油管内的压力波动有时还会在主喷射之后，使高压油管内的压力再次上升，达到令喷油器的针阀开启的压力，将已经关闭的针阀又重新打开产生二次喷油现象，由于二次喷油不可能完全燃烧，于是增加了烟度和碳氢化合物（HC）的排放量，油耗增加。此外，每次喷射循环后高压油管内的残压都会发生变化，随之引起不稳定的喷射，FE2 GK尤其在低转速区域容易产生上述现象，时不仅喷油不均匀，而且会发生间歇性不喷射现象。为了解决柴油机这个燃油压力变化的缺陷，现代柴油机采用了一种称为共轨的技术。 修理包 3803780 油泵总成 4935006 3949086 3939898 5362270 喷油器 kbel-p031 喷油器 1112100dlc1 喷油器 166-0149 油泵总成 3974596 阀组件 F00RJ01329 油嘴 DLLA150P861 油嘴 150P244HCO 输油泵 0 440 004 018 输油泵 0 440 008 089 单体泵 0428-6791 单体泵 0428-7049 单体泵 0428-6967 单体泵 0 414 287 016 单体泵 0 414 287 004 油泵总成 3604346 3034874 3655644 LED">ABSolute;top:0;border:0;width:undefinedpx;height:undefinedpx;" SANdbox="allow-forms allow-popUPS allow-popups-to-escape-sandbox allow-same-origin allow-scripts allow-top-navigation-by-user-activation" frameborder="0" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" src="https://googleads.g.doubleclick.net/pagead/ads?client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=3%3A32%2C4%3A32%2C8%3A134217728%2C9%3A134250632%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1081344%2C32%3A32&format=0x0&url=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%3D1&ea=0&flash=0&pra=5&wgl=1&uach=WyJXaW5kb3dzIiwiNy4wLjAiLCJ4ODYiLCIiLCI5OC4wLjQ3NTguMTAyIixbXSxudWxsLG51bGwsIjY0IixbWyIgTm90IEE7QnJhbmQiLCI5OS4wLjAuMCJdLFsiQ2hyb21pdW0iLCI5OC4wLjQ3NTguMTAyIl0sWyJHb29nbGUgQ2hyb21lIiwiOTguMC40NzU4LjEwMiJdXV0.&dt=1645497895630&bpp=2&bdt=37&idt=31&shv=r20220216&mjsv=m202202090102&ptt=9&saldr=aa&cookie=ID%3D138bd4a5c3f9dd5c-22e6327ab7c8007c%3AT%3D1621323454%3ART%3D1621323454%3AS%3DALNI_MZr6w-L6tDY0HVf8PxDU64fYTf-Jg&nras=1&correlator=1912013929455&frm=23&ife=1&pv=1&ga_vid=1433237903.1645497896&ga_sid=1645497896&ga_hid=806508190&ga_fc=0&nhd=1&u_tz=480&u_his=47&u_h=1080&u_w=1920&u_ah=958&u_aw=1920&u_cd=24&u_sd=1&DMC=8&adx=-12245933&ady=-12245933&biw=1920&bih=855&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=42531397%2C44750773%2C182982000%2C182982200%2C21067496%2C31062931&oid=2&pvsid=3904908034182239&pem=146&tmod=264894944&uas=0&nvt=1&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&eae=2&fc=1920&brdim=0%2C0%2C0%2C0%2C1920%2C0%2C1920%2C958%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=32772&bc=31&ifi=1&uci=1.xkefadpr8v9o&fsb=1&dtd=38" data-google-container-id="1.xkefadpr8v9o" data-load-complete="true"> |
