Kutora pressure sensor.
Mhepo inotora pressure sensor (ManifoldAbsolutePressureSensor), inozonzi MAP. Iyo yakabatana neakawanda manifold ine vacuum chubhu, uye neyakasiyana yekumhanyisa mutoro weinjini, shanduko yevacuum mune yakawanda yekudya inokonzereswa, uyezve kuramba shanduko mu sensor inoshandurwa kuita chiratidzo chevoltage kuti ECU iite. gadzirisa huwandu hwejekiseni uye yekubatidza nguva Angle.
Mune injini yeEFI, iyo intake pressure sensor inoshandiswa kuona huwandu hwekutora, iyo inonzi D-injection system (velocity density type). Iyo yekutora pressure sensor inoona huwandu hwekutora haina kunyatsoonekwa senge intake flow sensor, asi inoshandisa isina kunanga kuona, uye inobatwawo nezvakawanda zvinhu, saka kune nzvimbo dzakawanda dzakasiyana mukuona uye kugadzirisa kupfuura iyo intake flow sensor, uye kukanganisa kunogadzirwa kunewo hunhu hwayo.
Iyo yekumanikidza kupinza sensor inoona iyo yakazara kudzvanywa kweyakawanda manifold kuseri kweiyo throttle valve, iyo inoona yakanyatso kudzvanywa shanduko mune yakawanda zvichienderana nekumhanya kweinjini uye mutoro, uyezve inoshandura iyo chiratidzo chemagetsi kune injini yekudzora unit (ECU), uye iyo ECU inodzora iyo yakakosha jekiseni remafuta maringe nehukuru hwechiratidzo chemagetsi.
Iyo intake pressure sensor imhando ye sensor inoshandiswa kutarisa shanduko yekumanikidza mujini yekutora system. Inoita basa rakakosha mumotokari kana zvimwe zvemukati injini midziyo.
Iwo makuru mabasa ekutora pressure sensor ndeaya anotevera:
1. Kugadziriswa kwemafuta: Kupinza kudzvinyirira sensor kunogona kuyera kudzvinyirira mupombi yekutora uye kupa yakarurama kutora kudzvinyirira data kune injini yekudzora unit. Kubva pane iyi data, iyo control unit inogona kugadzirisa mafuta ekugovera kuti ape yakakwira yekupisa kushanda uye kuita.
2. Injini yekudzora: Chiratidzo chekutora kudzvinyirira sensor chinoshandiswawo pakuvandudza mazano ekugadzirisa injini. Rongedza nguva yekubatidza, nguva yevharuvhu, uye mamwe maparamita akakosha zvichienderana neshanduko mukudzvanywa kwekutora simba rekubuda kwemagetsi ari nani, hupfumi hwemafuta, uye kutonga kwekuburitsa.
3. Mhosva yekuona: Iyo inopinza yekumanikidza sensor inogona kutarisa mamiriro ekushanda kweiyo yekudyara system uye kutumira kodhi yekukanganisa kune iyo control unit kana anomaly ichiitika. Izvi zvinobatsira kuona uye kuongorora matambudziko ane chekuita nehurongwa hwekudya, sekudonha kwemhepo mupombi yekudyara, kutadza kwe sensor kana kudzvanywa.
Zvese mune zvese, iyo yekutora pressure sensor inopa chaiyo data yekudzora injini nekuyera kudzvanywa shanduko mune yekutora duct kuti ikwidze kupisa kwemoto, kuburitsa simba uye emission control. Inoita basa rakakosha mukushanda kwakajairwa uye kutadza kuongororwa kweinjini.
Ndezvipi zviratidzo zvekuputsika kwekushisa kwekushisa sensor?
01 Injini inofinha
Injini yakagomara chiratidzo chakajeka chekutadza kupinza tembiricha sensor. Kana iyo tembiricha yemvura inopihwa neinopinza tembiricha yemhepo kuECU yakakwira kupfuura chaiyo tembiricha yemvura, musanganiswa unova mutete, zvichikonzera kunonoka kweinjini uye kuderera kwesimba. Mukuwedzera, nokuti ECU haina kuwana chiratidzo chekushisa kwemvura yakarurama, musanganiswa unogona kunge wakanyanyisa kana wakatetepa, zvichiita kuti zvive zvakaoma kutanga motokari inotonhora. Nokudaro, kugadzirisa dambudziko iri, zvinowanzodiwa kugadzirisa iyo inopinza tembiricha yemhepo sensor.
02 Haikwanise kunyatso kudzora jekiseni remafuta
Kukuvadzwa kune yekutora tembiricha sensor kunozokonzera kusakwanisa kunyatso kudzora jekiseni remafuta. Izvi zvinodaro nekuti iyo inopinza tembiricha yemhepo sensor ine basa rekutarisa tembiricha yemhepo inopinda muinjini uye kupfuudza ruzivo urwu kumotokari yemagetsi control unit (ECU). Iyo ECU inogadzirisa vhoriyamu jekiseni remafuta zvichibva pane iyi data kuti ikwidze kuita kweinjini uye kushanda kwemafuta. Kana iyo sensor yakakuvadzwa, iyo ECU haizokwanisi kuwana chaiyo tembiricha yemhepo data, zvichikonzera isina kururama jekiseni remafuta. Izvi hazvingokanganisa mashandiro einjini chete, asi zvinogona kutungamira mukuwedzera kushandiswa kwemafuta.

Iyo fan inogara ichimhanya kana kusamhanya
Kukuvadzwa kweyekupinza tembiricha yemhepo sensor kunogona kuita kuti fan itenderere zvakajairika kana kwete. Kana paine dambudziko ne sensor tembiricha yekudyara, haigone kuverenga chaizvo tembiricha inotonhorera yeinjini, iyo inokanganisa fan control unit. Kana iyo sensor kuverenga yakadzikira, fan inogona kuramba ichimhanya mukuyedza kudzikisa tembiricha inotonhorera. Zvakasiyana, kana kuverenga kwakakwirira, fan inogona kusatanga, zvichiita kuti injini iwedzere kupisa. Nokudaro, maitiro asina kujairika emufanisi angave ari chiratidzo chakajeka chekukundikana kwekutora kwekushisa kwemhepo sensor.
04 Chiratidzo chekushisa kwemvura chisina kujairika
Abnormal tembiricha yemvura chiratidzo chiratidzo chiri pachena chekukanganisika kwemhepo kupinza tembiricha sensor. Kana paine dambudziko ne sensor tembiricha yekutora, inogona kusakwanisa kuverenga chaizvo tembiricha inotonhorera yeinjini, zvichikonzera kuverenga kusiri iko kwegeji yekushisa kwemvura. Kusarurama uku kunogona kuita kuti mutyairi afungisise tembiricha yeinjini, izvo zvinozokanganisa kuchengetedzwa kwekutyaira. Naizvozvo, kana chiratidzo chekushisa kwemvura chikaonekwa chisina kujairika, iyo yekupinda tembiricha yemhepo sensor inofanirwa kuongororwa nekukurumidza sezvinobvira uye kugadzirisa kwakakodzera kana kutsiva.
Kana iwe uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonere kana uchida zvigadzirwa zvakadaro.
