Urea sensor

Gawo lakutsogolo la sensor lostica limagwiritsidwa ntchito kudziwa kupanikizika kwa urea, ndipo gawo lakumbuyo limayambitsa kukakamiza kwa urea ndi mpweya wosakaniza chipinda chosakaniza. Gawolo litakwaniritsidwa: kumwa urea kumwa ndi zachilendo, ndipo galimotoyo imayatsa kuwala. Ngati nambala yolakwika ndi vuto lapano, injiniyo imangokhala ndi liwiro.

Kuyendera ndi Kusamalira:

Gwiritsani ntchito magetsi kuyeza magetsi otseguka a urea kupopera synsor, tengani kiyi ndikutsegula pulagi yayikulu, ndikuyeza 5V (mphamvu), 1). Kuyeza magetsi otsekeka, kokha poyambira batani, pulagi pa pulagi ndikuthyola magetsi kuti muyeze voliyumu, muyeso), 0/v (0/).

Zolakwika Zogwirizana:

Malingaliro owunikira:

1. Gwiritsani ntchito magetsi kuti muyeze voltuit magetsi otseguka ngati 5V (mphamvu), 0V (siginecha), zomwe zimasungidwa ndi makompyuta mulibe vuto.

2. Vuto la FC3571 likunenedwa, lomwe nthawi zambiri limadziwika kuti mzere wa siginecha ku mzere wamagetsi, bwalo lotseguka la waya kapena cholakwika cha chinthucho.

3. Vuto la FC3572 limanenedwa, lomwe limachitika chifukwa cha mzere wotsegulira wamagetsi kapena mzere wa siginecha, kuwonongeka kwamkati kwa chinthucho.

4. Fotokozani zolakwika za FC3573, nthawi zambiri plug imamasuka, kulumikizidwa kapena kuwonongeka kwamkati

Malingaliro oyang'ana:

1. Yang'anani pakuwona ngati kalankhulidwe ka Urea domp kuli kolumikizana, kulumikizana kwamadzi ndi kututa kwamadzi.

2. Pamene intero imapanikizika imaperekanso zovuta kapena zochepa, onani ngati sensor ya Sensor imasiyidwa kapena yowonongeka komanso ngati kusindikiza kwawonongeka.

3. Pofuna kupewa ma alarm abodza omwe amayamba chifukwa cha sensa ya urea. Zinthu zomwe zingasinthidwe kuti ziyesedwe.

4. Khodi yolakwika ya FC4239 imanenedwa. Nthawi zambiri, owunikira ECM omwe kukakamizidwa kwenikweni ndi kumapereka cholakwika. Mtengo wabwinobwino wokhazikika uyenera kukhala pakati pa 330 ~ 430KPa pomwe pampu ya urea doung yakonzeka kulowetsa (jakisoni wachita bwino) ndi gawo la jakisoni. Ngati ECM izindikira kuti zovuta zenizeni ndizokwera kwambiri kuposa 500kpa ndikupitilizabe kwa 8s, lidzanena zolakwa; Kapenanso gawo la jakisoni, lidzapereka kulakwa ngati kuli kopambana kuposa 150vu ndikupitiliza 0,5s. Chifukwa Chotheka:

Zachidule zatsekedwa, chitoliro cha jakisoni chimakhala ndikutsekedwa;

② The thehere urea makristals mkati mwa mapampu ya urea oletsedwa;

Kukakamiza kwa mpweya kumakwera kwambiri;

④ Onani ngati pepala lazachitsulo chosakanikirana cha chipinda chowonongeka.

5. Code ya FC4238 imanenedwa. Nthawi zambiri, owunikira ECM omwe kukakamizidwa kwenikweni ndi kutsika kwambiri ndipo amafotokoza cholakwika. Mtengo wabwinobwino wokhazikika uyenera kukhala pakati pa 330 ~ 430KPa pomwe pampu ya urea doung yakonzeka kulowetsa (jakisoni wachita bwino) ndi gawo la jakisoni. Chifukwa Chotheka:

Kupanikizika kwa mpweya;

② The thehere urea makristals mkati mwa mapampu ya urea oletsedwa;

③ Onani ngati sensor yolumikizira zitsulo zawonongeka ndipo ngati mphete yawonongeka;

Valavu yanjira ya gasi imawonongeka kapena scree screen imatsekedwa;

⑤ Valasi yama jekeseni;

6. Ngati zofunikira pamwambapa ndizabwinobwino, talingalirani kukonzanso deta kapena kusintha makompyuta.
