Fulumizitsa Udindo SENSOR: khalidwe, ntchito mfundo

Malo kachipangizo fulumizitsa malo (TPS) ali ndi yofunika zedi mu dongosolo, amene oyang'anira analandira mafuta mlingo. Malinga ndi chizindikiro ake Mtsogoleri ayamba kugwira ntchito yake, zomwe zikuphatikizapo tanthauzo la malo fulumizitsa. Ndi mmene mkulu liwiro kusintha chizindikiro imagwiridwa anaziika wa mphamvu ya ngo ndi mbamuikha, ndipo - chinthu chachikulu kudziŵa chofunika mafuta mlingo. Mu mode imene injini poyambira ndi kuyang'aniridwa khumudwitsidwa ngodya ya kuchimwa. Ndipo ngati ndi lotseguka ndi 75 peresenti kapena kuposa, galimoto ndi adamulowetsa ndi mode yoyeretsa. chizindikiro A wopereka fulumizitsa malo sensa, ndi kuyambira. Zinali pambuyo Mtsogoleri wayamba kulamulira pxx (yang'anira la kusakhala ndi chochita). Choncho mpweya okwanira imagwiridwa ndi injini.

Tikumbukenso kuti kachipangizo fulumizitsa malo ali dzina lina. limagwirira Izi otchedwa potentiometric mtundu womwenso resistors (zonse ndi variable). Kulimbikira kwa okwana pafupifupi 8 ohms.

A chizindikiro kusonyeza vavu malo akudyetsedwa kudzera ndi resistor kwa Mtsogoleri wa. tenepa ali ndi phindu kuti ndi pang'ono zosakwana 0,7 V. Ngati voteji ndi wamkulu kuposa 4 V, ndi ulamuliro wagawo amazindikira kuti valavu kwathunthu lotseguka. malo fulumizitsa kawirikawiri pa thupi lake ndi olumikizidwa kwa kasinthasintha olamulira. Olamulira ali ndi poyambira wapadera, amene wapangidwa ndi kagawo chamtanda. Kwenikweni, TPS chili mwa zomangira ziwiri.

N'kosatheka kutchula moyandikana sensa fulumizitsa malo. cholinga chake ndi kupanga ndi DC voteji njila kwa deta amene kutsegula ngodya ya khumudwitsidwa, ndi mafuta dongosolo jekeseni wa injini. Kutsinde kasinthasintha imatsogoleredwa mu mobwerera malangizo. limagwirira ichi chili ndi nozzle wapadera (throttling) a dongosolo mafuta jekeseni. Pali, ndithudi, anapereka zonse kwa unsembe izi. Tikumbukenso kuti thandizo la mankhwala sangakhale zochepa msewu mtunda.

Ndipo mmodzi mutu Ndikufuna kukhudza pa - ndi fulumizitsa malo kachipangizo Sandama. Pa makina aakulu, monga momwe tikudziwira, zimagwirira anakhazikitsa amafunika chisamaliro chapadera. Ndipo nthawi TPS amabwera mu ziyambe kukonzedwa. Choncho, limagwirira izi zosalongosoka ngati:

1. Pali mavuto pa zachabe.
2. Anatseka pansi HIV - stalling injini ya galimoto.
3. Jerks kuoneka pa mtengo akonzedwa.
4. Osagwira liwiro "zimatengedwa" pafupifupi onse mwanjira yomwe injini akuchita ntchito zake.

Pofuna kuwonetsetsa kuti TPS sachiza, muyenera fufuzani ndi kuchita mosavuta. Muyenera kuyatsa poyatsira, ndiye kuyeza voteji pakati osachiritsika slider ndi "thupi". Ngati voltmeter kuwerenga adzakhala wofanana 0,7 V kapena zochepa, chirichonse yachibadwa.
