Kwii-distributors (abahambisa) kwiimodeli ezininzi, i-rotors (i-sliders) exhotywe nge-anti-interference resistors isetyenziswa.Funda malunga nokuba yintoni isilayidi esine-resistor, yeyiphi imisebenzi eyenzayo ekutshiseni, ukuba isebenza njani kwaye isebenza njani, kunye nokukhetha okuchanekileyo kunye nokutshintshwa kwale nxalenye kwinqaku.
Yintoni imbaleki ye-resistor kwaye idlala yiphi indima kwi-distributor
I-slider ene-resistor yi-rotor yokusabalalisa ukutshatyalaliswa koqhagamshelwano kunye nenkqubo yokutshisa i-contactless, exhotywe nge-interference-suppressing resistor.
Nayiphi na inkqubo yokutshisa ngumthombo onamandla wokuphazamiseka kwerediyo ephazamisa ukwamkelwa kweenkqubo zerediyo kuwo onke amaqela, zombini kwimoto ngokwayo nakwisithuthi esidlula kufuphi.Ezi ziphazamiso ziviwa njengoko ucofa kunye nokuqhekeka, isantya sokuphindaphinda esonyuka ngokunyuka kwesantya se-injini.Ukuphazamiseka kuveliswa ngeentlantsi ezenzeka kwiindawo ezahlukeneyo zesekethe ye-high-voltage yenkqubo yokutshisa: kwi-spark gaps ye-spark plugs naphakathi koqhagamshelwano kwikhava kunye ne-slider yomthengisi.Xa i-spark ityibilika, uluhlu olubanzi lwemitha ye-electromagnetic lwenzeka - yiyo loo nto ukuphazamiseka kuvakala phantse kuwo onke amabhanti erediyo.Nangona kunjalo, i-spark ngokwayo inika i-radiation of low intensity, amandla aphambili akhutshwa ngamacandelo anxulumene ne-spark gap - iingcingo eziphezulu ze-voltage ezisebenza njengee-eriyali.
Ukulwa ne-phenomenon echazwe, izinto ezongezelelweyo zingeniswa kwi-high-voltage circuit ye-ignition system - ukusabalalisa okanye ukuchasana okugxininisiweyo.Iingcingo eziphezulu ze-voltage ezine-non-metallic conductors ezisembindini zisebenza njengokuchasana okusasazwayo.I-Resistors kwiiplagi ze-spark kunye ne-slider slider yenza njengezinto ezichasayo ezigxininisiweyo - le nkcukacha iya kuxoxwa ngakumbi.
Kutheni ukuqaliswa kwe-resistor kwi-high-voltage circuit kukhokelela ekunciphiseni kwinqanaba lokuphazamiseka?Isizathu silula kakhulu.Xa kukho ukuphuka kwe-gap ye-spark, i-high-frequency currents ihamba nge-conductor edibeneyo kuyo, ekhokelela ekuphumeni kwamaza erediyo ngulo mqhubi.Ukubekwa phakathi kwesithuba se-spark kunye nomqhubi we-resistor kunye nokuchasana kwamawaka amaninzi e-ohms atshintsha umfanekiso: kunye ne-capacitances kunye ne-inductances abasoloko benayo abaqhubi, isihluzo esilula senziwe esinqumla icandelo le-high-frequency yokuphazamiseka. .Enyanisweni, ukunqunyulwa okupheleleyo akukwenzeka, nangona kunjalo, i-amplitude ye-high-frequency currents kwi-wire iyancipha ngokukhawuleza, okukhokelela ekuhlahleni okuphindaphindiweyo kwinqanaba lokuphazamiseka kwerediyo kwi-high-voltage circuit ye-ignition system.
Ukuba sichaza zonke ezi zingasentla kwisilayidi somthengisi, ke isithuba sentlantsi apha siqhagamshelene nesigqubuthelo kunye noqhagamshelwano olusondeleyo lwesilayidi, kunye neengcingo eziphezulu ze-voltage ezihamba ukusuka kwikhoyili ukuya kwisilayidi kwaye ukusuka kubafowunelwa ukuya kwi-slider. amakhandlela asebenza njengee-eriyali.Ngaloo ndlela, apha i-resistor iphakathi kwabaqhubi ababini, kodwa ukunyanzeliswa okukhulu kokuphazamiseka kwenzeka kwintambo evela kwikhoyili, kwaye ukunyanzeliswa kokuphazamiseka kwiingcingo zekhandlela kwenzeka ngenxa yokuchasana kweengcingo ngokwazo kunye ne-resistors eyakhelwe kumakhandlela.
Umsasazi wokulayita kunye nendawo yesilayidi kuyo
Yiyo loo nto esi sixhathisi sibizwa ngokuba sisichasi-siphazamiso (okanye sicinezela ngokulula).Nangona kunjalo, ukongeza ekulweni nokuphazamiseka kwerediyo, i-resistor yenza eminye imisebenzi emininzi:
● Ukuthintela (okanye ukunciphisa ubunzulu) ukutshiswa koqhagamshelwano lwekhava yomthengisi kunye nesilayidi ngokwaso;
● Ukunciphisa amathuba okuqhawuka kombane kweminye imithombo yombane onamandla;
● Ukwandisa ubomi benkonzo bamakhandlela kunye nezinto ezinxulumene noko;
● Ukwandisa ixesha lokukhutshwa kwe-spark, oko kwezinye iimeko kwandisa ukuzinza kwe-injini.
Kutheni kusenzeka konke oku?Isizathu kukuchasana nombane wangoku, okwenza i-resistor.Ngenxa yokuchasana kwi-high-voltage circuit, xa ukukhutshwa kuhamba, amandla akhoyo ayancipha - kwanele ukuba i-spark phakathi kwe-electrode yamakhandlela ivuthe umxube ovuthayo, kodwa akwanelanga ukunyibilika kwendawo yesinyithi. i-electrodes kunye nabafowunelwa kumthengisi.Ngelo xesha, amandla agcinwe kwi-coil ahlala efana, nangona kunjalo, ngenxa yokwanda kokuchasana kwesekethe, ayinikwa amakhandlela ngokukhawuleza, kodwa ixesha elithile - oku kukhokelela ekwandeni ixesha lokukhupha, eliqinisekisa ukutshiswa okuthembekileyo komxube kwiisilinda.
Ke, i-resistor enye kuphela kwisilayidi somthengisi womlilo wenza imisebenzi emininzi eyandisa ukusebenza kakuhle kwe-injini kunye nokuthuthuzela kwesithuthi.
Uyilo kunye neempawu zesilayidi esine-resistor
I-slider (i-rotor) ene-resistor iqukethe iinxalenye ezininzi: i-cast case, abafowunelwa ababini abaqinileyo (ophakathi, ukuphumla kwi-ember kwi-cover yokusabalalisa, kunye necala elinye) kunye ne-cylindrical resistor ebekwe kwindawo ekhethekileyo yokuphumla.Umzimba wenziwe ngezinto zokufakelwa kombane, oonxibelelwano badla ngokulungiswa kuyo kunye ne-rivets.Iipleyiti ze-Springy zenziwe kubafowunelwa, phakathi kwayo i-resistor ixinyiwe.Kwinxalenye engezantsi yomzimba wesilayidi, umjelo oqingqiweyo wenziwa ukulungisa umsabalalisi wokutshisa kwi-shaft.
Ngokwendlela yokufaka i-resistor, kukho iindidi ezimbini zezilayidi:
● Ngesixhasi esinokubuyiselwa;
● Nge-resistor engatshintshiyo - inxalenye izaliswe kwi-recess kunye ne-insulating compound ekhethekileyo esekelwe kwi-epoxy resin okanye izinto ze-vitreous.
Isilayidi esine-resistor
Abagijimi basebenzisa i-resistors enamandla yoyilo olukhethekileyo kunye neeterminals zokuphela, ezenzelwe ukufakwa phakathi koqhagamshelwano lwe-springy.Kwiimoto zasekhaya, i-resistors ene-resistance ye-5.6 kOhm isetyenziswa rhoqo, nangona kunjalo, i-resistors enokumelana ne-5 ukuya kwe-12 kOhm inokufumaneka kwii-slider ezahlukeneyo.
Ngokuxhomekeke kuhlobo lomthengisi, isilayidi sinokuxhonywa ngokulula kwi-shaft yokusabalalisa (ngokuqhelekileyo iindawo ezinjalo zine-T-shaped), okanye zixhonywe ngezikrufu ezibini kwi-ignition time regulator (ezi nxalenye zenziwe ngendlela ye-cylinder flat) .Kuzo zombini iimeko, i-resistor ifakwe ngaphandle kwe-slider, evula ukufikelela ekuhloleni kwayo kwaye, ukuba kunokwenzeka, ukutshintshwa.
Imibuzo yokukhetha kunye nokutshintshwa kwesilayidi esine-resistor
I-resistor ebekwe kwisilayidi ixhomekeke kwimithwalo ebalulekileyo yombane kunye neyomatshini, ngoko ke ekuhambeni kwexesha inokungaphumeleli - ukutshisa okanye ukuwa (ukuqhekeka).Njengomthetho, ukuchithwa kwe-resistor akuvimbeli i-injini, kodwa kuphazamisa kakhulu ukusebenza kwayo - injini ayifumani amandla apheleleyo, iphendula kakubi kwi-pedal yegesi, "i-troit", i-detonates, njl. Inyaniso kukuba iintlantsi ziyakwazi ukutyibilika kwi-resistor etshisiweyo okanye eyahlulahlula, ngoko ke inkqubo yokutshisa iyaqhubeka nokusebenza, kodwa ngokuphulwa kunye nokusebenza kancinci.Xa iimpawu ezinjalo zivela, kufuneka uqale ususe isigqubuthelo somthengisi (oku kufuneka kwenziwe kuphela xa injini imisiwe kwaye i-terminal isusiwe kwibhetri), qhaqha kwaye uhlole isilayidi.Ukuba i-slider iyinto eqhelekileyo, ngoko inokususwa ngaphandle kwezixhobo, kwaye ukuba inxalenye ixhunyiwe kwi-regulator ye-ignition timeing, ke izikrufu ezimbini kufuneka zikhutshwe nge-screwdriver.
Ukuba, xa uhlola i-resistor, akukho zibonakaliso zangaphandle zokungasebenzi kwayo (ayitshisi okanye iphukile), okanye i-resistor igcwele i-compound, ngoko kufuneka uhlolisise ukuchasana kwayo kunye nomhloli - kufuneka ilale kuluhlu lwe 5-6 kOhm (kwezinye iimoto - ukuya kwi-12 kOhm, kodwa ingabi ngaphantsi kwe-5 kOhm).Ukuba ukuchasana kudla ngokungapheliyo, ke i-resistor iphosakele kwaye kufuneka itshintshwe.Inxalenye yohlobo olufanayo kunye nokuchasana kufuneka kuthathwe ukutshintshwa - oku kuphela kwendlela yokuqinisekisa ukuba i-resistor iya kuwela kwindawo kwaye inkqubo yonke iya kusebenza ngokuqhelekileyo.Ukutshintsha i-resistor kwehla ngokulula ukususa inxalenye endala (kukulungele ukuyikhupha nge-screwdriver) kunye nokufaka entsha.Ukuba i-resistor igcwele i-compound, ngoko kuya kufuneka utshintshe isilayidi sonke - kwiimoto zasekhaya, ukutshintshwa okunjalo kuya kubiza amashumi amaninzi eeruble.
Isilayidi esinekhompawundi-ezaliswe
IsixhasiIsixhasi esinokubuyiselwa kwisilayida
Ngokuqhelekileyo, abanini beemoto bafaka i-wire jumpers endaweni ye-resistors - akuvumelekanga ngokungqongqo ukwenza oku.Ukungabikho kwe-resistor kwandisa izinga lokuphazamiseka kwerediyo kwaye kunokuphazamisa ukusebenza kwenkqubo yokutshisa (kubandakanywa nokukhokelela ekunxibeni okunzulu koqhagamshelwano lwe-slider kunye nekhava yokusabalalisa, kunye ne-electrodes ye-spark plugs).Kananjalo akukhuthazwa ukuba utshintshe isilayidi kunye ne-resistor kwi-slider elula kwiinkqubo zokutshisa kunye neengcingo eziphezulu ze-voltage zokumelana ne-zero.Kuphela ezo ntlobo kunye neemodeli zezilayidi ezicetyiswa ngumvelisi we-ignition distributor kufuneka zisetyenziselwe ukutshintshwa.
Ngokukhetha okufanelekileyo kunye nokutshintshwa kwesilayidi kunye ne-resistor (okanye kuphela i-resistor), inkqubo yokutshisa iya kusebenza ngokuthembekileyo kunye "nongcoliseko" oluncinci lomoya werediyo.
