IAC: abin da shi ne, babban gazawar, manufa

Wannan labarin za a yi la'akari da IAC, abin da shi ne, da manufa na aiki, da asali saituna. Akwai ma za a gaya game da lokacin da bukatar maye gurbin rago gudun kayyadewa Vaz motoci. Ka sani cewa zamani mota da aka cushe da dama masu auna sigina da actuators. Wadannan sun hada da iko da idling. Tare da shi na goyon bayan da engine gudun. A lokacin da ka karya IAC motor fara aiki talauci, akwai bayyanar cututtuka irin su m juyawa daga cikin crankshaft, shi dai kullum tsalle. A wasu lokuta, yana yiwuwa cewa engine tsaya a nan ba, kuma ba zai fara.

Mene ne IAC?

Da farko, bari mu yi la'akari da waje da kuma ciki bayyanar da IAC. Mẽne ne, za ka koya daga wannan labarin. An shigar kusa da maƙura, tare da shi sanya don kula da engine gudun a matakin 700 zuwa 900 juyin minti daya. Wannan yana cika ta hanyar daidaitawa da iska samar da maƙura na'urar. Azahiri idling mai kula kama wani kananan roba akwatin, ciki wanda suke kananan fatar Motors (ko solenoid). Amma wasu model da wani cylindrical siffar, Ya sanya daga karfe. A stepper mota ko solenoid actuates sanda na karfe, wanda ya buɗe kuma rufe iska wadata.

Running da engine a rago

Malalaci gudun tsari

Idan za mu tuna carbureted injuna, da engine gudun a idling kayyade ta hanyar musamman sukurori. A kan aiwatar da saitin da ya wajaba wajen saka idanu da oxygen abun ciki na shaye gas, da crankshaft gudun. A hanya kanta sosai lokaci-cinyewa kuma bukatar wararrun da suka kawo shi. Lokacin da na farko ya tilasta man fetur allura tsarin, da hanya da aka muhimmanci Sauki.

A gaskiya ma, cikin IAC, abin da shi ne tattauna a cikin labarin, shi ne actuator, maimakon haska. Yana yana da nasaba da wani lantarki kula naúrar, wanda ya tattara duk bayanan a kan mota a real lokaci. Bisa ga bayanai, da kwamfuta ya haifar da wani abin hawa iko duka muhimmanci sigogi na ciki konewa engine.

Lura cewa Laifi kayyadewa idling fitilar «rajistan shiga engine» ba haske a sama a mafi yawan lokuta. Kuma ku tuna cewa kayyadewa - wannan ba shi ne haska. IAC - wannan actuator, tun da shi ba ya auna.

Lokacin amfani da kewaye IAC akwai daya kawai drawback - shi ko da yaushe yayi kokarin dattako da juyawa daga cikin crankshaft. Duk da haka, yayin da tuki bukatar wannan kusan vuya, kamar yadda ya zama dole don daidaita lokacinta kawai a lokacin da ya sauya sheka gudu ko braking.

Mene ne gwamnoni

Akwai da dama iri na rago controls. Zai yiwu mafi sauki - shi dogara ne a kan solenoids. Lokacin da ta samar da wani irin ƙarfin lantarki wadata, ya miƙa karfe core. Saboda haka, da kewaye nassi fara rufe, ragewa iska wadata. Kuma mataimakin versa. Amma akwai wani kadan drawback. Gwamnoni da irin wannan ne kawai biyu matsayi - bude da kuma rufe tashar. Domin samar da wata lafiya gyara, ka sau da yawa amfani da ƙarfin lantarki ga solenoid. Kafin ka duba IAC, tabbatar da cewa a lokacin da ƙonewa ne powered on.

Nau'i na biyu - a Rotary iko. Ka'idar aiki ne kusan kama da baya daya. Iyakar abin da bambanci - shi ne gaban na'ura mai juyi, wanda ya fitar bude da kuma rufe da kewaye tashar. Amma mafi yadu jog idling, wanda ya kunshi 4 windings da wani maganadisu a cikin siffar wani zobe. A kowane daga cikin windings amenable ƙarfin lantarki daga lantarki iko naúrar.

Major lalacewar da rago gudun tsari

Idan kana kokarin gane asali engine kanka, kuma kana da wani shakka cewa kayyadewa na idling ne daga oda, shi wajibi ne su san ainihin gazawar bayyanar cututtuka. Kuma da sosai farko shi ne cewa gudun tsallen da aka idling. Har ila yau, a lokacin da gas sallama ya auku ake kira rataya - turnovers ga wani lokaci jinkirta da daya darajar.
