I-GM Buick Chevrolet Electronic Pressure Switch Sensor 12573107

Umfutho kawoyela

Kubhekiselwa ohlelweni oluncane lwe-electromechanical oluhlanganisa izinzwa ezincane, ama-actuator, amasekhethi okucubungula amasignali nokulawula, amasekethe esixhumi esibonakalayo, ukuxhumana kanye nokunikezwa kwamandla. Okuvame ukusetshenziswa uhlobo lwe-silicon piezoresistive kanye nohlobo lwe-silicon capacitive, kokubili okuyizinzwa ze-electronic micromechanical ezikhiqizwa kumawafa e-silicon. Ngokuvamile, sisebenzisa inzwa yokucindezela uwoyela ukuthola ukuthi ungakanani uwoyela osekuwoyela wenjini yemoto, futhi siguqule isignali etholiwe ibe isignali esingayiqonda, okusikhumbuza ukuthi ungakanani uwoyela osele, noma ukuthi singafinyelela kude kangakanani. hamba, noma ngisho ukukhumbuza imoto ukuthi idinga ukufakwa uphethiloli.

Inzwa yokushisa kwamanzi

Ngaphakathi kune-thermistor ye-semiconductor, lapho izinga lokushisa liphansi, kukhulu ukumelana; Ngokuphambene nalokho, ukuphikisana okuncane, kufakwe ejazini lamanzi le-injini ye-cylinder block noma ikhanda le-cylinder futhi lixhumana ngokuqondile namanzi okupholisa. Ukuze uthole izinga lokushisa kwamanzi okupholisa injini. Ngokwalolu shintsho, iyunithi yokulawula i-elekthronikhi ikala izinga lokushisa lamanzi okupholisa injini. Uma izinga lokushisa liphansi, kukhulu ukumelana. Ngokuphambene, kuncane ukumelana. Ngokwalolu shintsho, iyunithi yokulawula ye-elekthronikhi ikala izinga lokushisa lamanzi okupholisa injini njengenombolo yokulungiswa komjovo kaphethiloli kanye nesikhathi sokuthungela. Okusho ukuthi, singakwazi ukwazi ukusebenza kwemoto, ukuma noma ukunyakaza, noma ukuthi isinesikhathi esingakanani ihamba ngezinga lokushisa lamanzi enjini.

Ukugeleza kwenqwaba yomoya

Umsebenzi wayo ukubona ukungena komoya kwenjini, nokuguqula ulwazi lokungenisa komoya lube amasiginali kagesi ukuze aphume, bese uwadlulisela ku-ECU. Siyazi ukuthi ukushayela kwemoto kudinga idivayisi yokuthungela ukuze uthole umfutho oya phambili. Ngakho-ke, inani lokwehla kwamandla emali liyisisekelo se-ECU ukubala isikhathi sokujova uphethiloli, inani lomjovo kaphethiloli kanye nesikhathi sokuthungela sedivayisi yokuthungela lapho imoto ibaswa. Umsebenzi wayo ukusenza sikwazi ukusheshisa kangcono futhi sinciphise imoto.
