Engxenyeni eyinkimbinkimbi yesistimu yokulawula ukukhishwa kwemoto yakho, i-vapor canister (evame ukubizwa nge-charcoal canister) idlala indima ebalulekile, nakuba ivame ukunganakwa. Kuyisici esibalulekile sesistimu ye-Evaporative Emission Control (EVAP), eyenzelwe ngqo ukuvimbela imisinga kaphethiloli ethathwe ethangini lakho likaphethiloli ukuthi ingaphunyuki emoyeni.

Ezingxenyeni eziyinhloko zesitsha segesi kukhona amalahle acushiweyo, into enezimbobo eziningi kakhulu enendawo enkulu kakhulu. Lawa malalahle asebenza njengesipontshi, kodwa esikhundleni sokumunca uketshezi, amunca izinswelaboya zophethiloli—lokhu kusho ukuthi izinswelaboya zophethiloli zinamathela ebusweni bezinhlayiya zamalahle.

Inqubo ingahlukaniswa izigaba ezimbili eziyinhloko:

Lapho imoto yakho icishiwe, uphethiloli ethangini uvamise ukubila. Lezi zinswelaboya ezilimazayo zama-hydrocarbon azikhululwa emoyeni. Kunalokho, zidluliselwa ngamapayipi bese zigcinwa ngaphakathi esitsheni segesi. Amalahle acushiweyo abamba futhi agcine izinswelaboya ngempumelelo.

Lapho injini isebenza futhi isifinyelele isimo esithile sokusebenza, iyunithi lokulawula injini (ECU) livula i-solenoid valve ebizwa nge-purge valve. Umoya ohlanzekile udonswa ungene ku-canister nge-vent. Lokhu kudlula komoya kuthwala imisinga kaphethiloli egcinwe ku-charcoal, ibasuse "iyihlanze" futhi iyithumele ku-intake manifold yenjini ukuze ishwe ngendlela evamile ngesikhathi sokushiswa.

Ngenkathi umsebenzi wayo oyinhloko ukuvikela imvelo, indima ye-vapor canister iyimihlanga:

Kunciphisa kakhulu ukukhishwa kwamacarbohydrates angashile (HC), okuyinto enkulu ekubangeni umusi womoya ongcolile nokungcola komoya. Lokhu kusiza izimoto ukuthi zihambisane nemithetho eqinile yokukhishwa komoya emhlabeni.

Ngokubamba nokusebenzisa kabusha lezi ziphepho zikaphethiloli emuva ku-injini ukuze zishiswe, kuthuthukisa ukusebenza kahle kukaphethiloli. Uqinisile usebenzisa uphethiloli obungase uchitheke.

Igcina ibhalansi efanele yengcindezi ethangini likaphethiloli. I-canister engasebenzi kahle noma uhlelo oluvinjiwe lungaholela engcindezi engemihle, okwenza kube nzima ukugcwalisa ithangi likaphethiloli ngesikhathi sokugcwalisa (okwaziwa njengokuthi "ukucisha kwe-fuel pump").

Ngokufingqiwe, i-vapor canister iyisistimu elula kodwa elihlakaniphile. Isebenza njengomqaphi, ibamba ukungcola ngaphandle komzamo, yonga uphethiloli, futhi iqinisekise ukuthi imoto yakho iyasebenza njengoba ihloselwe - konke lokhu ngaphandle kokuba umshayeli aqaphele ukusebenza kwayo okuthule. Ukugcinwa kahle kwalesi sici kubalulekile kokubili endaweni ehlanzekile kanye nokusebenza kahle kwemoto.
