博世DLLA144P234喷油嘴

 

油量的多少，取决于喷油时间的长短。喷油器按电磁线圈的控制方式不同，分为电压驱动式和电流驱动式两种。电压式也分低阻和高阻的，高阻的可以接12V电，低阻的只能接低电压，错接在12V上时间稍长会烧线圈。喷油时，电脑提供的电压是恒定的，比如说12V，断油时马上变为0V，这个变化是瞬时的，就像是电脑语言里面的0和1一个概念，中间没有0.5之说。换言之,这是一个脉动的直流电信号，并非什么交流电等等一类的名词。交流电什么概念呢?正负交错才叫交流电。好像汽车里面除了发电机整流器以前的部分,基本上接触不到交流电。当喷油嘴堵塞时,喷油不畅,或者喷油嘴间隙有积碳及胶合物,达不到设计的喷油量或雾化效果,才需要清洗。编辑本段故障排除喷孔堵塞
　　可用通针进行疏通，疏通后要经纬仔细地清洗。针阀体大平面与喷油嘴主体平面接触不良，或针阀圆柱面磨损较大。若针阀体大平面与喷油嘴主体平面接触不良，可用氧化铬涂在平板上进行“8”字形研磨；若针阀圆柱面磨损较大，应成对更换针阀偶件。
密封不良
　　针阀和针阀体密封不良，造成喷油嘴雾化不良或滴油。 　　这种故障可用细的氧化铬或牙膏，涂在针阀端的密封带上，但千万不要涂到圆柱部分，再将针阀插入针阀体，边敲边转直到密合。研磨石必须将氧化铬或牙膏洗去。
油路有空气
　　在油路中有空气。只需将油路中的空气排除即可。DLLA160S995 DLLA144S992 DLLA151S985 DLLA138S983 DLLA140S976 DLLA151S972 DLLA154S970 DLLA136S943 DLLA150S925 DLLA142S924 DLLA150S896 DLLA146S890 DLLA144S889 DLLA150S870 DLLA150S853 DLLA144S842 DLLA150S838 DLLA150S836 DLLA150S815 DLLA150S762 DLLA150S753 DLLA150S739 DLLA155S713 DLLA155S710 DLLA149S394 DLLA150S344ND71 DLLA142S1142 DLLA156S344ND111 DLLA150S374ND94 DLLA160SND171 DLLA150SND154 DLLA155SND199 DLLA151S907 DLLA142S1013 DLLA130S1253 DLLA142S1264 DLLA142S1266 DLLA150S1070 DLLA150S315ND145 DLLA160S295ND147 DLLA160S295ND152 DLLA142S315ND159 DLLA155SND160 DLLA160SND171 DLLA155SND180 DLLA155SND182 DLLA155SND199 DLLA150SND200 DLLA155SND217 DLLA160SND226 DLLA150SND227 DLLA150SND229 DLLA150SND230 DLLA160SND236 DLLA150SND238 DLLA150SND240 DLLA150SND241 DLLA160SND243 DLLA160SND249 DLLA160SND251 DLLA160SND253 DLLA150SND254 DLLA155SND263 DLLA150SND265 DLLA150SND272 DLLA150SND273 DLLA153SM029 DLLA156SM 139A DLLA156SM058 DLLA155SM061 DLLA145SM012 DLLA155SM049 DLLA153SN029 DLLA155SN083 DLLA146S334N168 DLLA160SN171 DLLA150SN289 DLLA166S374N379 DLLA151S354N381 DLLA150S334N385 DLLA16S561N389 DLLA154S284N393 DLLA144S354N403 DLLA150S394N404 DLLA152S354N406 DLLA166S346N408 DLLA138S364N409 DLLA150S394N411 DLLA150S394N412 DLLA154S324N413 DLLA150S374N414 DLLA137S374N417 DLLA143S384N418 DLLA154S334N419 DLLA160S354N420 DLLA154S344N421 DLLA160S295N422 DLLA154S344N424 DLLA151S354N425 DLLA154S344N428 DLLA148S354N429 DLLA105S304N433 DLLA160S307N435 DLLA158S325N437 DLLA154S374N438 DLLA146S344N439 DLLA145S344N453 DLLA142S354N454 DLLA146S394N455 DLLA148S324N456 DLLA162S384N457 DLLA155S365N458 DLLA154S424N459 DLLA142S374N461 DLLA150S374N464 DLLA150S355N467 DLLA150S424N470 DLLA148S334N472 DLLA148S324N473 DLLA154S304N474 DLLA153S295N475 DLLA154S364N476 DLLA150S424N477 DLLA150S285N484 DLLA160S324N486 DLLA150S355N490 DLLA150S345N492 DLLA103S314N495 DLLA146S284N496 DLLA144S364N497 DLLA133SN500 DLLA142S344N501 DLLA142S354N502 DLLA154SN503 DLLA133SN504 DLLA145SN506 DLLA160S325N507 DLLA140SN510 DLLA155SN515 DLLA155SN515B DLLA151SN517 DLLA160SN519 DLLA145SN523 DLLA154SN526 DLLA160S325N527 DLLA152SN529 DLLA155SN532 DLLA154SN533 DLLA150SN534 DLLA155SN536 DLLA160SN538 DLLA160SN539 DLLA157SN544 DLLA148SN545 DLLA155SN546 DLLA142S344N547 DLLA150SN548 DLLA150SN549 DLLA157SN551 DLLA143SN553 DLLA150SN555 DLLA150SN557 DLLA149SN558 DLLA160SN564 DLLA160SN566 DLLA160SN567 DLLA160SN570
