Throttle operation

Iyo throttle valve chimwe chezvakakosha zvikamu zveiyo intake system yeinjini yekupisa mukati. Mumotokari, iri pakati pekutora manifold nemhepo sefa. Painjini dzedhiziri, throttle haidiwi, asi pamainjini emazuva ano ichiri kuisirwa kana paine emergency. Mamiriro acho akafanana neinjini dzepeturu kana dziine valve yekusimudza control system. Basa guru revhavha ye throttle ndeyekupa uye kugadzirisa mhepo inoyerera inodiwa pakuumbwa kwemhepo-mafuta musanganiswa. Saka, kugadzikana kweinjini yekushandisa modes, chiyero chemafuta ekushandisa uye maitiro emotokari sese zvinoenderana nekushanda kwakaringana kwekuvhunduka.

Kudzipa mudziyo

Kubva pane inoshanda yekuona, iyo throttle valve is a bypass valve. Munzvimbo yakavhurika, kudzvanywa muhurongwa hwekutora kwakaenzana nemhepo. Sezvo ichivhara, inoderera, ichiswedera kune vacuum kukosha (izvi imhaka yekuti mota iri kushanda sepombi). Ndicho chikonzero nei iyo vacuum brake booster yakabatana kune yakawanda yekudyara. Zvimiro, iyo damper pachayo iplate yakatenderedza inogona kutenderera 90 madhigirii. Imwe shanduko yakadaro inomiririra kutenderera kumwechete kubva pakuvhurwa kwakazara kusvika pakuvhara kwevharuvhu.

Device accelerations

Butterfly valve block (module) inosanganisira zvinotevera zvinhu:

• Iyo kesi yakashongedzerwa nemanozzles akasiyana. Iwo akabatana neventilation masisitimu anoteya mafuta uye inotonhorera mhute (kupisa damper).
• Activation inofambisa valve kana mutyairi akatsikirira accelerator pedal.
• Position sensors kana potentiometers. Vanoyera throttle kuvhura angle uye vanotumira chiratidzo kune injini yekudzora unit. Mune masisitimu emazuva ano, maviri throttle position control sensors akaiswa, anogona kunge ari kutsvedza kubata (potentiometers) kana magnetoresistive (asina-kubata).
• Idling regulator. Izvo zvinodikanwa kuchengetedza iyo yekuseta kumhanya kwe crankshaft mune yakavharwa mode. Ndiko kuti, iyo diki yekuvhura angle yekuvhunduka inobatwa inovimbiswa kana iyo accelerator pedal haina kushushikana.

Mhando uye modes dzekushanda kweiyo vharuvhu vharuvhu

Mhando ye throttle actuator inosarudza dhizaini yayo, maitiro ekushanda uye kutonga. Inogona kuva yemagetsi kana yemagetsi (electronic).

Zvokuimba kutyaira mudziyo

Ekare uye yakachipa mhando dzemotokari dzine mechanical valve actuator umo accelerator pedal yakabatana zvakananga kune wastegate uchishandisa yakakosha tambo. Iyo mechanical actuator ye butterfly valve ine zvinhu zvinotevera:

• accelerator (gasi chitiviri);
• dhonza nekumonyorora marevhisi;
• tambo yesimbi.

Kudzvinyirira iyo accelerator pedal inomutsa iyo mechanic system ye levers, tsvimbo uye tambo, zvichiita kuti damper itenderere (kuvhurika). Somugumisiro, mhepo inotanga kupinda muhurongwa, uye musanganiswa wemhepo-mafuta unoumbwa. Iyo yakawanda mweya inopihwa, iyo yakawanda mafuta inoyerera uye saka kumhanya kunowedzera. Kana iyo throttle iri munzvimbo isina basa, iyo throttle inodzokera kunzvimbo yakavharwa. Pamusoro peiyo huru modhi, masystem masisitimu anogona zvakare kusanganisira manyorero ekutonga kweiyo throttle chinzvimbo uchishandisa yakakosha knob.

Nheyo yekushanda kwemagetsi dhiraivha

Rudzi rwechipiri uye rwemazuva ano rwekuvhundutsa kunotyisa ndeye electronic throttle (ine electric drive uye electronic control). Hunhu hwayo hukuru:

• Iko hakuna yakananga mechani kupindirana pakati pedal uye damper. Pane kudaro, kutonga kwemagetsi kunoshandiswa, izvo zvinokutenderawo kuti uchinje injini torque pasina kudzvanya pedal.
• Injini idling inodzorwa otomatiki nekufambisa iyo throttle.

Iyo yemagetsi system inosanganisira:

• throttle chinzvimbo uye gasi sensors;
• electronic engine control unit (ECU);
• kudhonza kwemagetsi

Iyo yemagetsi throttle control system zvakare inofunga masaini kubva kune kutapurirana, mamiriro ekunze system, brake pedal position sensor uye cruise control.

Paunodzvanya chinomhanyisa pedal, iyo accelerator pedal position sensor, ine maviri akazvimirira potentiometers, inoshandura kuramba mudunhu, inova chiratidzo kune yemagetsi control unit. Iyo yekupedzisira inotumira murairo wakakodzera kune yemagetsi drive (motor) uye inoshandura throttle. Nzvimbo yaro, zvakare, inodzorwa nemasensa akakodzera. Vanotumira ruzivo nezve nzvimbo itsva yevharuvhu kuECU.

Ikozvino throttle position sensor is potentiometer ine multidirectional zviratidzo uye inopikisa zvachose ye8 kOhm. Iyo inowanikwa mumuviri wayo uye inopindirana nekutenderera kweshaft, ichishandura kona yekuvhura yevhavha kuita DC voltage.

Munzvimbo yakavharwa yevhavha, mhepo inenge iine 0,7 V, uye munzvimbo yakazaruka yakakwana, inenge 4 V. Ichi chiratidzo chinogamuchirwa nemutongi, nokudaro kudzidza nezvehuwandu hwekuzarura throttle. Kubva pane izvi, huwandu hwemafuta anopiwa hunoverengwa.

Iyo damper position sensor inobuda curves ine multidirectional. Chiratidzo chekutonga ndicho musiyano pakati pezvinhu zviviri. Iyi nzira inobatsira kubata nekukanganisa kunogona kuitika.

Kubatira basa uye kugadzirisa

Kana iyo throttle valve ikakundikana, module yako inoshanduka zvachose, asi mune dzimwe nguva zvakakwana kugadzirisa (kugadzirisa) kana kuchenesa. Naizvozvo, kuitira kunyatsoshanda kwemagetsi anotyairwa masisitimu, zvinodikanwa kugadzirisa kana kudzidza throttle. Iyi nzira inosanganisira kuisa data pane yakanyanyisa nzvimbo dzevhavha (kuvhura nekuvhara) muchiyeuchidzo chemutongi).

Throttle adaptation inosungirwa mune zvinotevera kesi:

• Paunenge uchitsiva kana kugadzirisa zvakare yemagetsi injini yekudzora unit yemota.
• Paunenge uchitsiva chinotyisa.
• Kana injini isina kugadzikana pakusaita basa.

Iyo throttle valve unit inodzidziswa pachiteshi chebasa uchishandisa midziyo yakakosha (scanners). Kupindira kusina unyanzvi kunogona kutungamirira kukugadzirisa kusina kunaka uye kuora kwekuita kwemotokari.

Kana paine dambudziko nema sensors, mwenje wenyevero uchauya mupanera yemidziyo kukuzivisa iwe nezvedambudziko. Izvi zvinogona kuratidza zvese zvisizvo marongero uye kuzorora kwevanobatika. Kumwe kusashanda kwakajairika kudonha kwemhepo, iyo inogona kuongororwa nekuwedzera kwakanyanya mukumhanya kweinjini.

Pasinei nekureruka kwekugadzira, zviri nani kupa kuongororwa uye kugadziriswa kwevhavhavhavha kune nyanzvi ine ruzivo. Izvi zvinovimbisa hupfumi, kugadzikana uye, kunyanya kukosha, kushanda kwakachengeteka kwemotokari uye kuwedzera hupenyu hweinjini.
