（1）变换转速试验。使发动机怠速运转,然后由怠速向低速,由低速向中速,再由中速向高速加大节气门进行试验,同时结合逐缸断火法和在加机油口处听诊等方法反复进行。FE2 GK响声随着转速的升高而,抖动节气门时,在加油的瞬间异响。 (2)断火试验。在怠速、中速和高速情况下,逐缸反复进行断火试验。如某缸断火后响声明显减弱或消失,在复火的瞬间又能立即出现,则可断定为该缸连杆轴承响。(3)检查机油压力。诊断中要注意检查机油压力。如果响声,又伴随有机油压力低,这往往成为区别连杆轴承响与活塞销响、活塞敲缸响的重要依据。 喷油器修理包 23670-0L070 095000-7761 阀板 295040-9440 喷油器 0 445 120 529 喷油器 28348371 6510702433 A6510702433 A6510704987 28342997 喷油器 0 445 110 011 喷油器 0 445 110 081 喷油器 BEBE4D24001 喷油器 0 445 110 260 喷油器 4964172/4955526 喷油器 3076703 喷油器 23209-0C010 23250-0C010 泵总成 3075537-BC83 喷油器 20440388 喷油器 21371672 喷油器 7421340611 21340611 喷油器 20510724 喷油器 20547350 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=1645405349433&bpp=1&bdt=36&idt=28&shv=r20220216&mjsv=m202202090102&ptt=9&saldr=aa&cookie=ID%3D138bd4a5c3f9dd5c-22e6327ab7c8007c%3AT%3D1621323454%3ART%3D1621323454%3AS%3DALNI_MZr6w-L6tDY0HVf8PxDU64fYTf-Jg&nras=1&correlator=2932556305879&frm=23&ife=1&pv=1&ga_vid=1809893511.1645405349&ga_sid=1645405349&ga_hid=1662410261&ga_fc=0&nhd=1&u_tz=480&u_his=38&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=42531398%2C44750773%2C182982000%2C182982200%2C44756894%2C44758227%2C21067496%2C31062931&oid=2&pvsid=4197894050354243&pem=146&tmod=875727929&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.fyhv3trc71tn&fsb=1&dtd=33" data-google-container-id="1.fyhv3trc71tn" data-load-complete="true"> |
