Magawo a Magalimoto a Dongfeng Cummins Idn Tuner 4921322

Sensor yowonjezereka (map).

Imalumikiza chakudya chambiri ndi chubu cha vacuum, ndipo ndi katundu wothamanga wa injini, imazindikira kuti ikhale yosasinthika ya senso ya ecu kuti ikonzekere mankhwala osokoneza bongo ndikuyamwa.

Mu injini ya EFI, sensor yoponderezedwa imagwiritsidwa ntchito kudziwa kuchuluka kwa mpweya, komwe kumatchedwa D-mtundu wa jekeseni (mtundu wa Velocity). Inshuwaration Air Perser imazindikira kuti mpweya watha mpweya wabwino m'malo mwa nthawi yayitali ngati ikani mpweya woyenda. Nthawi yomweyo, zimakhudzidwanso ndi zinthu zambiri, kotero pali zosiyana pakati pa kupezeka kwa sensor, ndi zolakwa zomwe zimayambitsidwa nazo zimakhalanso ndi zochitika zake.

Sensor kupanikizana imazindikira kukakamira kwakukulu kwa kudya komwe kumayambitsa. Imazindikira kusintha kwa kupanikizika kwathunthu mu gawo malingana ndi liwiro la injini ndi katundu, kenako ndikutembenuza mphamvu ya siginecha yoyang'anira injini (Ecu). Ecu imawongolera kuchuluka kwa jakisoni wokhazikika malinga ndi magetsi osayina.

Mfundo yofunika kugwirira ntchito

Pali mitundu yambiri yazomwe zimaphatikizika, monga varistar ndi Cakucator. Chifukwa cha zabwino zoyankha mwachangu, kulondola kwapamwamba, kukula kang'onong'ono komanso kusinthasintha kosinthika, ma varser amagwiritsidwa ntchito pompopompo.

kapangidwe

Selor yopsinjika imagwiritsa ntchito chitseko chokakamizidwa, ndipo kupsinjika kumawonjezera mlatho wa tiriko pa diicon diaphragm yomwe ingasinthidwe. Chip Chip ndichimodzi mwazovuta, ndipo opanga onse opanga ma sys ali ndi mapiko awo omwe amakakamizidwa, zina zomwe zimapangidwa mwachindunji, ndipo zinazo ndikugula mwachindunji kuchokera kwa akatswiri opanga zip. Nthawi zambiri, tchipisi chimapangidwa mwachindunji ndi sensor opanga kapena tchipisi a ASC zimagwiritsidwa ntchito pazomwe amagwiritsa ntchito. Chipsi ichi chimaphatikizidwa kwambiri, ndipo kupsinjika chip, mawonekedwe a Emplifring, chizindikiro cha Emc ndi ROM kuti agwirizane ndi sensor yomwe imaphatikizidwa ndi chip. Sensor yonse ndi chip, ndipo chip chimalumikizidwa ndi pini ya pini yolumikizira.
