Mota yekutora pressure sensor function
Iwo makuru mabasa emotokari yemhepo inotora pressure sensor anosanganisira zvinotevera zvinhu:
Ipa injini yekuremerwa chiratidzo : Iyo yekudyara yekumanikidza sensor inopa iyo injini mutoro chiratidzo kuECU (injini yekudzora Unit) nekuyera shanduko yekumanikidza mune yakawanda yekudyara. Aya masaini anobatsira ECU kunyatso kudzora jekiseni kupuruzira upamhi uye kuvhurika kuvhurika kuti ikwidze kuita kweinjini uye hupfumi hwemafuta.
Dzora jekiseni remafuta uye nguva yekubatidza : Sensors inoshandura shanduko yekumanikidza mune yakawanda yekudyara kuita masaini emagetsi eECU kugadzirisa jekiseni remafuta uye yekubatidza nguva Angle. Kana iyo injini ikawedzera, kudzvanywa muhuwandu hwekudya kunoderera, iyo sensor inobuda chiratidzo inowedzera, uye ECU inowedzera huwandu hwejekiseni remafuta uye inononoka kuvhenekera kumberi kweAngle. Zvikasadaro, jekiseni remafuta richadzikiswa uye kupisa kuchave kumberi.
Gadzirisa nguva yekuvhura vharafu uye jekiseni remafuta: Muinjini ine yemagetsi valve control system, iyo inopinza yekumanikidza sensor inoona kudzvanywa shanduko mupombi yekupinza uye inoverenga nemazvo huwandu hwemhepo mucylinder imwe neimwe kugadzirisa nguva yekuvhura valve uye vhoriyamu jekiseni remafuta. Izvi zvinobatsira kuvandudza kushanda uye simba rekubuda kweinjini.
dzivirira injini : Iyo yekutora pressure sensor inogonawo kuona isina kujairika mamiriro ekushanda einjini, senge abnormal pressure shanduko, uye kutumira masaini ku control system kuchengetedza injini. Izvi zvinobatsira kudzivirira kukuvara kweinjini nekuda kwekuremerwa kana zvimwe zvinhu.
Kushanda musimboti : Iyo yekudya yekumanikidza sensor inowanzobatanidzwa kune yekudyara manifold kuburikidza ne vacuum chubhu uye inonzwa shanduko yevacuum mune yakawanda yekutora. Sezvo injini yekumhanyisa uye mutoro uchichinja, kudzvanywa mune yekudyara manifold kuchachinja, uye kuramba mukati me sensor kuchachinjawo zvinoenderana, nokudaro kuburitsa chiratidzo chemagetsi. Ichi chiratidzo chinogamuchirwa neECU uye chinoshandiswa kugadzirisa jekiseni remafuta uye nguva yekudzima.
Kukanganisa kukanganisa : Kana iyo yekudyara yekumanikidza sensor yakakuvadzwa, inogona kutungamira kune isina kugadzikana isingaiti kumhanya, kukurumidza kukurumidza, kunetseka kutanga, kuwedzera kushandiswa kwemafuta uye mamwe matambudziko emotokari. Panguva imwecheteyo, injini yekutadza mwenje ichavhenekerwa, uye inoenderana kodhi kodhi ichachengetwa.
Naizvozvo, kugara uchiongorora uye kugadzirisa kwekutora kudzvanywa sensor kwakakosha kuti uve nechokwadi chekushanda kwakajairika kwemotokari.
Manifold Absolute Pressure Sensor (MAP) chinhu chakakosha muinjini yemotokari inocherekedza shanduko yekuchinja muhuwandu hwekutora uye inoshandura shanduko idzi kuita masaini emagetsi kuti anyatso kudzora neinjini yemagetsi control unit (ECU). Iyo yekutora pressure sensor yakabatana kune yekudyara manifold kuburikidza ne vacuum chubhu uye inogona kunzwa shanduko yevacuum mune yakawanda yekudyara. Nekumhanya kwakasiyana kweinjini uye mutoro, kuramba mukati me sensor kuchachinja, iyo inozoshandurwa kuita chiratidzo chevoltage yeECU kugadzirisa huwandu hwejekiseni remafuta uye nguva yekudzima.
Kushanda musimboti
Nheyo yekushanda yekutora kudzvinyirira sensor inobva pakupikisa kuchinja kunokonzerwa nekuchinja kwekumanikidza. Tora varistor type inlet pressure sensor semuenzaniso, chikamu chayo chepakati isilicon diaphragm yakagadzirwa nepiezoresistive mhedzisiro ye semiconductor. Kana kudzvinyirirwa kweiyo manifold manifold kuchiita pasilicon diaphragm, iyo diaphragm inokanganisa, zvichikonzera shanduko mukukoshera kwayo. Iyi shanduko inoshandurwa kuva chiratidzo chemagetsi, iyo inowedzerwa uye inopfuudzwa kuECU. Zvichienderana nemagetsi anogamuchirwa emagetsi, ECU inonyatso kudzora jekiseni remafuta kuti rienderane nezvinodiwa zvakasiyana zvekutyaira.
Mhando nemashandisirwo
Kune marudzi akawanda emagetsi ekudzvinyirirwa masensa, akajairika ndee semiconductor varistor, vacuum bellows uye capacitive. Pakati pavo, semiconductor varistor inoshandiswa zvakanyanya muD-mhando jekiseni system nekuda kwemabhenefiti ayo ekukurumidza kupindura, kurongeka kwepamusoro, hukuru hudiki uye kuchinjika kuisirwa. Iyo capacitive sensor inoshandisa diaphragm kuti igadzire chinhu chinobatikana chine inosiyana capacitance kukosha, uye inoshandura shanduko yekumanikidza kuita chiratidzo chemagetsi nekuyera dunhu.
Maintenance uye kukanganisa kuongororwa
Iko kutadza kuongororwa kweiyo intake pressure sensor inowanzobatanidza kutarisa kana chiratidzo chayo chekubuda chiri mukati meyakajairika renji. Kana iyo sensor inobuda chiratidzo isina kujairika, kuita kweinjini kunogona kuderedzwa kana kusagadzikana. Munguva yekugadzirisa, nguva nenguva tarisa kubatana uye kuiswa chisimbiso kwe sensor kuti ive nechokwadi chekuti inoshanda nemazvo.
