Mota yekutora pressure sensor function
Monitor kutora manifold pressure
Iyo yekutora pressure sensor yakabatana kune yekudyara manifold kuburikidza ne vacuum chubhu kuti ione iyo yakakwana yekumanikidza shanduko mune yekutora manifold kuseri kwe throttle valve munguva chaiyo. Idzi shanduko dzekumanikidza dzakanyatsoenderana nekumhanya uye mutoro weinjini, uye masensa anoshandura shanduko idzi dzemagetsi kuita masaini emagetsi anotumirwa kuECU.
Optimize jekiseni remafuta
Zvichienderana nechiratidzo chekumanikidza chinopihwa ne sensor, iyo ECU inonyatso kuverenga huwandu hwemafuta anodiwa neinjini. Kana iyo injini ikawedzera, kudzvinyirira kwakawanda kunoderera, iyo sensor inobuda chiratidzo inowedzera, uye ECU inowedzera vhoriyamu jekiseni remafuta zvinoenderana. Zvikasadaro, inoderera. Uku kugadziridzwa kwakasimba kunovimbisa kushanda kwakanaka kweinjini pasi pemamiriro akasiyana ekushanda.
Kudzora nguva yekudzima
Iyo yekutora pressure sensor inobatsirawo ECU kugadzirisa nguva yekudzima. Kana iyo injini ikawedzera, iyo yekubatidza mberi Angle inononoka zvakakodzera. Kana mutoro ukaderedzwa, iyo yekubatidza mberi Angle inoenderera mberi. Kugadziriswa uku kunobatsira kuvandudza simba reinjini uye hupfumi hwemafuta.
Yekubatsira kuyerera kwemhepo kuverenga
Mune Type D mafuta jekiseni system, iyo inopinza yekumanikidza sensor inoshandiswa pamwe chete nemhepo yekuyerera mita kuyera huwandu hwekupinda zvisina kunanga, nekudaro kuverenga kuyerera kwemhepo zvakanyanya. Iri basa rekubatana rinowedzera kukwirisa jekiseni remafuta uye kuita kweinjini.
Kuona kukanganisa uye kudzivirira
Iyo intake pressure sensor inokwanisa kuona kusarudzika kudzvanya shanduko mune yakawanda yekudyara, senge mavharogi kana kudonha, uye kutumira masaini kuECU. Izvi zvinobatsira kuona kutadza kweinjini nenguva uye kutora matanho ekudzivirira kudzivirira kumwe kukuvara.
Mhando uye nheyo dzekushanda
Zvakajairwa kutora kumanikidza sensors kunosanganisira varistor uye capacitive marudzi. Iyo varistor sensor inoshandura kupikisa kuburikidza nekugadziriswa kwesilicon diaphragm uye inoburitsa chiratidzo chemagetsi. Iyo capacitive sensor inoshandura iyo capacitance kukosha kuburikidza ne deformation ye diaphragm uye inoburitsa iyo pulse chiratidzo. Masensa ese ari maviri anoshandiswa zvakanyanya mumotokari dzemazuva ano nekuda kweiyo yepamusoro uye nekukurumidza kupindura.
Sum up
Intake pressure sensor ndechimwe chezvakakosha zvemotokari injini yekudzora system, basa rayo haringogumiri pakutarisa kudzvanywa, asi zvakare rinosanganisirwa mujekiseni remafuta, nguva yekubatidza, kuyerera kwemhepo uye kuona kukanganisa. Nekunyatso kudzora ma paramita aya, masensa anovandudza zvakanyanya kuita kweinjini, hupfumi hwemafuta uye kuburitsa.
Mota yekutora kudzvanywa sensor (intake pressure sensor) ndechimwe chezvinhu zvakakosha zveiyo jekiseni jekiseni system, kutadza kwayo kuchaita kuti injini yekudzora unit (ECU) isakwanise kunyatso gadzirisa chiyero chemhepo-mafuta. Zvinotevera ndizvo zviratidzo zvikuru uye zvikonzero zvekukanganisa:
Core chiratidzo mharidzo
Kunetsa kana kusakwanisa kutanga injini
Abnormal sensor masaini anokonzeresa iyo ECU kutadza kuverenga iyo chaiyo jekiseni jekiseni remafuta, zvichikanganisa kudzima uye jekiseni remafuta.
Kana mutsara we sensor wakaputsika kana kupfupika-kutenderera, iyo ECU inogona kurasikirwa zvachose nekutora kumanikidza data, zvichikonzera kutadza kwekutanga.
Abnormal power output
Kuwedzera kusimba kana kuderera kwesimba: sensor haigone kugadzirisa chiratidzo neshanduko yedhigirii yevacuum, uye ECU inokanganisa kutorwa kwemhepo, zvichikonzera kutsauka kwehuwandu hwemafuta.
s erratic idle speed : Kana musanganiswa wacho wakanyanya kukora kana kuti wakatetepa, injini inogona ku jitter kana kukurumidza kuchinja.
combustion anomaly
Utsi hutema hunobva papombi yekuburitsa : musanganiswa wakakora zvakanyanya kuti ukonzerese kupisa kusingaite, kunowanzo onekwa nekukasira.
kupinza pombi kupisa : Kana musanganiswa wanyanya kutetepa, gasi risina kupiswa rinobatidza mupombi inopinza.
Mhosva inokonzera classification
Iyo sensor pachayo
Internal strain gauge kana kutadza kwedunhu (eg semiconductor strain gauge failure).
Iyo inobuda chiratidzo voltage inodarika yakajairwa huwandu (senge voltage drift).
kukundikana kwakabatana nekunze
Iyo vacuum hose yakavharwa kana kubuda, izvo zvinokanganisa kutapurirana kwekumanikidza.
Kuiswa kwakashata kwechisimbiso mhete kunotungamira kuvharika kweiyo inlet yekumanikidza (signal mutation panguva yekumanikidza).
Diagnostic zano
Preliminary examination
Tarisa uone kana mwenje wemhosva wakabatidzwa (mamwe mamodheru anokonzeresa iyo OBD kukanganisa kodhi).
Tarisa iyo vacuum pombi yekubatanidza uye sensor wiring harness.
Professional bvunzo
Shandisa iyo diagnostics kuverenga chaiyo-nguva data hova uye enzanisa yakajairwa kumanikidza kukosha.
Edza kana iyo sensor inobuda voltage inosiyana nekuvhurwa kwe throttle.
Tip : Kana zviratidzo zviri pamusoro zvichiperekedzwa nezvikanganiso (zvakadai seP0105/P0106), sensor uye maseketi ane hukama anofanira kutanga atariswa. Kuregeredza kwenguva refu kunogona kukonzera kukuvadzwa kune matatu-nzira inoshandura inoshandura kana kuwedzera kukuru kwekushandisa mafuta.
Kana iwe uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonere kana uchida zvigadzirwa zvakadaro.
