Izizathu ezi-3 eziyinhloko zokuthi uwoyela wenjini ungene kusihlungi somoya

Isihlungi somoya siklanyelwe ukucupha udoti, ukungcola nokunye ukungcola, hhayi uwoyela. Kwesinye isikhathi, uma umakhenikha wesevisi yendawo ethatha indawo yesihlungi somoya, uchwepheshe uzobonisa ukuthi uwoyela wenjini utholakele; kungaba ngaphakathi kwendlu yesihlungi somoya noma eyakhelwe kusihlungi esisetshenzisiwe. Nakuba uwoyela osesihlungini somoya ngokuvamile engelona uphawu lokwehluleka kwenjini okuyinhlekelele, akufanele neze uzitshwe. Ake sibheke izizathu ezi-3 eziyinhloko zokuthi kungani uwoyela ungena kusihlungi somoya.

1. Ivalvu evalekile ye-crankcase ventilation (PCV).

I-valve ye-PCV ixhunywe endaweni yokungenisa umoya, ngokuvamile ngepayipi le-raber vacuum, elisetshenziselwa ukukhulula i-vacuum ngaphakathi kwe-crankcase yenjini. Le ngxenye ivamise ukugxunyekwa phezu kwekhava yevalvu yekhanda lesilinda, lapho ukucindezela kugeleza ukusuka engxenyeni engezansi yenjini ngamakhanda amasilinda kuphumele endaweni yokungena. Ivalvu ye-PCV iyafana nesihlungi sikawoyela wenjini ngokuthi ngokuhamba kwesikhathi ivaleke ngemfucumfucu eyeqile (uwoyela wenjini kulokhu) futhi kufanele ishintshwe ngokwezincomo zomkhiqizi wemoto yakho. Uma i-valve ye-PCV ingashintshwa njengoba kunconyiwe, uwoyela oweqile uzophuma ngevalvu ye-PCV bese ungena ohlelweni lokungenisa umoya.

Iliphi ikhambi? Uma i-valve ye-PCV evalekile itholakala iwumthombo wamafutha enjini ngaphakathi kwesihlungi sakho somoya noma isistimu yokungenisa umoya, kufanele ishintshwe, kuhlanzwe umoya owuthathayo, futhi kufakwe isihlungi somoya esisha.

2. Amasongo episton agugile.

Umthombo wesibili ongaba khona kawoyela wenjini ovuza endlini yesihlungi somoya amasongo e-piston. Amasongo e-piston afakwe onqenqemeni olungaphandle lwamapiston ngaphakathi kwegumbi elivuthayo. Amasongo aklanyelwe ukudala ukusebenza kahle komlilo futhi avumele amanani amancane kawoyela wenjini ukuthi aqhubeke nokugcoba igumbi elivuthayo langaphakathi ngesikhathi sokushaywa kwepiston ngakunye. Lapho amaringi eguga, ayaxega futhi angabangela ukufutheka kwamafutha, okuvame ukuvela njengentuthu eluhlaza okwesibhakabhaka ephuma epayipini le-exhaust yemoto ngenkathi ushayela. Ezigabeni zokuqala zokugqokwa kweringi ye-piston, ukuphuma kukawoyela ngokweqile kungabangela ukucindezela okukhulu ngaphakathi kwe-crankcase, eqondisa amafutha amaningi nge-valve ye-PCV futhi ekugcineni angene emoyeni njengoba kuphawuliwe ngenhla.

Iliphi ikhambi? Uma ubona uwoyela wenjini kusihlungi sakho somoya noma indawo engenisa umoya, umakhenika ochwepheshile angase atuse ukuthi uhlole ukucindezela. Lapha umakhenikha uzofaka igeji yokuminyanisa emgodini ngamunye wepulaki yenhlansi ukuze ahlole ukuminyanisa kusilinda ngayinye. Uma ukucindezela kuphansi kunalokho okufanele kube khona, imbangela ngokuvamile igqoke amasongo e-piston. Ngeshwa, lokhu kulungisa akulula njengokushintsha i-valve ye-PCV. Uma ama-piston rings agugile ehlonzwa njengomthombo, kungaba yisu elihle ukuqala ufune enye imoto, njengoba ukufaka ama-piston namaringi cishe kuzobiza ngaphezu kwenani lemoto.

3. Imigudu kawoyela evalekile

Isizathu sokugcina esingaba isizathu sokuthi uwoyela wenjini ungene ohlelweni lokungenisa umoya futhi ekugcineni uvale isisefo somoya kungenxa yokuvaleka kwamaphaseji kawoyela. Lesi sibonakaliso ngokuvamile sivela lapho uwoyela wenjini nesihlungi kungashintshwanga njengoba kunconyiwe. Lokhu kubangelwa ukunqwabelana ngokweqile kwe-carbon deposits noma udaka ngaphakathi kwe-crankcase yenjini. Lapho uwoyela ugeleza ngendlela engafanele, umfutho kawoyela owedlulele unqwabelana enjinini, okwenza ukuba amafutha amaningi aphushwe nge-valve ye-PCV angene emoyeni.

Iliphi ikhambi? Kulokhu, kwanele ukushintsha ngezikhathi ezithile uwoyela wenjini, isihlungi, i-valve ye-PCV bese ubuyisela isihlungi somoya esingcolile. Kodwa-ke, uma kutholakala amaphaseji kawoyela avimbekile, ngokuvamile kuyatuswa ukuthi uwoyela wenjini ushiswe futhi ushintshe isihlungi sikawoyela okungenani kabili phakathi namamayela ayi-1,000 okuqala ukuze kuqinisekiswe ukuthi amaphaseji kawoyela enjini awanawo udoti.

Uyini umsebenzi wesihlungi somoya?

Isihlungi somoya ezinjinini eziningi zesimanje zangaphakathi ezivuthayo sitholakala ngaphakathi kwendawo yokudonsa umoya, ebekwe phezu kwenjini. Ixhunywe ohlelweni lomjovo kaphethiloli (noma i-turbocharger) futhi iklanyelwe ukunikeza kahle umoya (i-oxygen) ohlelweni lukaphethiloli ukuze luxubane nophethiloli ngaphambi kokuthi lungene endaweni evuthayo. Umsebenzi oyinhloko wesihlungi somoya ukukhipha izinhlayiya zokungcola, uthuli, imfucumfucu nokunye ukungcola ngaphambi kokuba umoya uxubane nophethiloli owuketshezi (noma uphethiloli wedizili) bese uphenduka umusi. Uma isihlungi somoya sivaleka ngemfucumfucu, singaphumela ekwehleni ukusebenza kahle kukaphethiloli kanye nokuphuma kwamandla enjini. Uma uwoyela utholakala ngaphakathi kwesihlungi somoya, lokhu kungase futhi kube nomthelela omkhulu ekusebenzeni kwenjini.

Uma wenza ukunakekelwa okujwayelekile emotweni yakho, iloli, noma i-SUV futhi uthola uwoyela wenjini ngaphakathi kwesihlungi somoya noma indawo engenisa umoya, kungaba umqondo omuhle ukuthi umakhenikha ochwepheshe eze kuwe ukuze azohlolwa endaweni. Ukuhlonza umthombo oyinhloko ngendlela efanele kungakongela inani elikhulu lemali ekulungiseni okukhulu noma ngisho nokushintsha imoto yakho kusenesikhathi.
