在确认缸处于压缩上死点后，首先调整缸气门间隙,6DF3U机型每旋转120°曲轴转角按发火顺序1-5-3-6-2-4逐缸调整气门间隙。气门间隙用厚薄规调整（见图5)。各缸均调整好后应复查一遍并起动柴油机，在怠速状态凭观察和手感检查调整是否有误。 更换柴油机机油 柴油机运行时的高温将使机油不断老化变质，运行时产生的金属磨损杂质将使机油受到污染，因此定期更换机油对延长柴油机的使用寿命有重大意义。在严寒地区使用的柴油机机油更换周期应缩短，如在-10℃以下工作的柴油机机油更换的周期应改为为行驶里程5000km(或运行100小时)。 更换机油应在柴油机热态时，因为热的机油更容易带走机油中的杂质并流干净。放完机油后把放油螺塞（换用新垫圈）拧紧后再加注新机油。 07 检查喷油器的喷油压力和喷雾质量 检查喷油器应在的试验台上进行，当以每分钟30次速度泵油时，在压力25～26Mpa时，喷油器喷雾要均匀，断油要，并听到特殊的清脆响声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" src="https://googleads.g.doubleclick.net/pagead/ads?client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=1%3A32776%2C2%3A32776%2C8%3A134217728%2C9%3A134250504%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=WyJXaW5kb3dzIiwiMTAuMCIsIng4NiIsIiIsIjkxLjAuNDQ3Mi4xMDEiLFtdXQ..&tt_state=W3siaXNzdWVyT3JpZ2luIjoiaHR0cHM6Ly9hZHNlcnZpY2UuZ29vZ2xlLmNvbSISInN0YXRlIjozfSx7Imlzc3Vlck9yaWdpbiI6Imh0dHBzOi8vYXR0ZXN0YXRpb24uYW5kcm9pZC5jb20iLCJzdGF0ZSI6N31d&dt=1623921391840&bpp=2&bdt=90&idt=21&shv=r20210615&cbv=%2Fr20190131&ptt=9&saldr=aa&cookie=ID%3D138bd4a5c3f9dd5c-22e6327ab7c8007c%3AT%3D1621323454%3ART%3D1621323454%3AS%3DALNI_MZr6w-L6tDY0HVf8PxDU64fYTf-Jg&nras=1&correlator=5525575464520&frm=23&ife=1&pv=2&ga_vid=843877787.1623921392&ga_sid=1623921392&ga_hid=2135977283&ga_fc=0&nhd=1&u_tz=480&u_his=41&u_java=0&u_h=1080&u_w=1920&u_ah=958&u_aw=1920&u_cd=24&u_nplug=3&u_nmime=4&adx=-12245933&ady=-12245933&biw=1920&bih=855&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=182982000%2C182982200%2C31060957%2C31060972%2C31060973%2C21067496&oid=3&pvsid=2910216266296002&pem=146&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php&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.fd9ertc4mrsj&fsb=1&dtd=27" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" allow="conversion-measurement" data-google-container-id="1.fd9ertc4mrsj" data-load-complete="true"> |
