Yini ephuka kumjovo wedizili?

Ikhwalithi ye-atomization kaphethiloli, ukuvutha, ngisho namandla kanye ne-torque yenjini kuncike ekusebenzeni kwama-injection. Ngakho-ke noma nini lapho ubona izimpawu zokuhluleka komjovo emotweni yakho, phuthuma kumakhenikha. Akufanelekile ukuqinisa, ngoba uma ushayela isikhathi eside ngama-injection anephutha, imiphumela izoba yingozi kakhulu. Awuqinisekile ukuthi ungabona kanjani ukungasebenzi kahle nokuthi yini engadiliza kuma-injection? Sijahile ngezincazelo!

Uzofundani kulokhu okuthunyelwe?

• Yiziphi izingxenye zesistimu yomjovo ezingaphumeleli kakhulu?
• Ungawubona kanjani umjovo ophukile?

Ngikhuluma nje

Isici esibiza kakhulu nesisebenza kakhulu sohlelo lomjovo yipompo, kodwa ngenhlanhla, lena akuyona imojula ephuthumayo kakhulu. Ama-injection aphuka kaningi. Ukulimala kuzo kungabangelwa, isibonelo, isimo esibi sezimpawu, izimbobo zezinaliti ezivaliwe noma ukugqwala kwezindlu.

Uma ufuna ukwazi ukuthi ama-nozzles asebenza kanjani, funda okufakiwe kwangaphambilini kulolu chungechunge. → Lusebenza kanjani uhlelo lomjovo kadizili?

Kungani ama-injection kadizili ephuka?

Ama-injection, nakuba engavumelani nalokhu, azosebenza ngaphansi kwezimo ezinzima. Lawa madivaysi azacile futhi anembe afaka uphethiloli wedizili ngaphansi kwengcindezi enkulu kumasilinda enjini izikhathi eziningi lapho ushayela. Namuhla ingcindezi ohlelweni lomjovo isuka ku-2. imigoqo ukuya phezulu. Engxenyeni yekhulu leminyaka edlule, lapho isimiso sisakazeka kabanzi, ama-injection kwadingeka amelane cishe nengxenye yokucindezela.

Uma kucatshangwa ukuthi ikhwalithi kaphethiloli ilungile, ama-injection kufanele agijime ibanga elingu-150 XNUMX km ngaphandle kwezinkinga. amakhilomitha. Nokho, ngophethiloli we-diesel, izinto zingahluka. Ngenxa yalesi sizathu, kwenzeka ukuthi ukufaka esikhundleni ama-injection kuyadingeka kaningi kunalokho umkhiqizi asikisela. Impilo yesevisi iyancipha ibe ngu-100-120 km noma ngaphansi. Ukuncipha kwayo kuncike ezimeni zokusebenza kwenjini nendlela oyisebenzisa ngayo.

Yini engagqekeza ama-injection?

Izihlalo zamavalvu okulawula. Zilinyazwa yizinhlayiya kuphethiloli, ngokuvamile i-sawdust. Lokhu kuholela ekuvuzeni kwe-injector, i.e. "Ukugcwalisa", kanye namaphutha ekunqumeni ukucindezela kwenduku ye-hydroaccumulator. Ukugqokwa kwezihlalo kungaholela ekusebenzeni okungalingani kanye nezinkinga ezinzima zokuqala.

• Iziqu ze-valve. Noma yimuphi umonakalo entweni yokuphotha engaphakathi komjovo - kungakhathaliseki ukuthi ukonakala ngenxa yokungagcobi ngokwanele, ukuvala noma ukunamathela ngenxa yokunamathela ngenxa yezinga eliphansi likaphethiloli - kubangela ukuba ama-injection avuze futhi aphuphume. Futhi lapha umphumela awulingani, ukusebenza kahle kwenjini.
• Ama-sealants. Ukugqokwa kwazo kuboniswa iphunga elibonakalayo lamagesi okukhipha umoya noma ukuhayiza noma umaka lapho injini isebenza. Izigxivizo zenziwa ngendlela yamawasha ayindilinga amancane acindezela i-injector esihlalweni esisekhanda lesilinda. Abiza indibilishi futhi ukuwashintsha kuwumdlalo wezingane, kodwa ukungafinyeleli izinsuku eziwumnqamulajuqu kungaba nemiphumela emibi kakhulu - amagesi akhipha umoya aphuma egunjini lomjovo adala isilonda esivimbayo. Lokhu kuzokwenza kube nzima ukususa umjovo owonakele futhi kungase kuphoqe ngisho nekhanda lonke lesilinda ukuba lihlakazwe ngale njongo. Ukulungisa kuleli cala kuzobiza futhi kube nzima.
• Futha izimbobo. Uma ithiphu le-nozzle ligugile, ukufafaza akusebenzi kahle. Isibaseli asilethwa ngokunembile futhi esikhundleni salokho siconsa sisuka phezulu ngezikhathi ezingahleliwe. Ukunganeli kokunikezwa kukaphethiloli we-diesel ezidingweni kuholela ekungeneni kwamandla enjini ngaphansi komthwalo, izinkinga zokufinyelela i-rpm, kanye nokwenyuka kokusetshenziswa kukaphethiloli nokusebenza okunomsindo. Ezinhlelweni ze-Common Rail, ukuvala izimbobo ezinokungcola okuqinile okuvela kuphethiloli wezinga eliphansi, ngeshwa, ukungasebenzi kahle futhi kungamisa imoto ngesikhathi esingalindelekile.
• Inaliti. Kokubili ukuguga nokudabuka kukhoni yenaliti ehambayo ngaphakathi kwethiphu lomjovo kanye nokubopha kwayo kudala umonakalo omkhulu. Ukuquleka kwenzeka uma usebenzisa uphethiloli ongcolile ogeza futhi ugcobe inaliti ngesikhathi sokusebenza. Ubani owayengacabanga ukuthi ukwehluleka kwalesi sici esincane kungaholela ekungeneni kukaphethiloli kumafutha enjini, nasezimotweni ezintsha, ngisho nokulimala kwezihlungi zezinhlayiya?
• Isici se-Pisoelectric. Ezinjinini ezinohlelo lwesitimela olujwayelekile, ikhoyili nayo ingalimala. Lokhu kubangelwa ukugqwala kwesibambi se-nozzle noma isifunda esifushane ku-solenoid. Kungase futhi kubangelwe ukuhlangana okungalungile noma ukusetshenziswa kwengxenye engahambisani nezincomo zomkhiqizi.

Ungakubona kanjani ukungasebenzi kahle komjovo?

Imvamisa ibika ukungasebenzi kahle. intuthu emnyama iphuma epayipini lokukhipha umoya, ikakhulukazi lapho uqala futhi ukusheshisa okubukhali. Lokhu kudalwa uphethiloli omningi ohlinzekwa ngumjovo kumasilinda enjini. Lokhu kunciphisa amandla enjini futhi kwandisa ukusetshenziswa kukawoyela. Uphawu lokulimala komjovo nalo ukusebenza kanzima, ukushaya injini.

Ku-Common Rail, ukuxilongwa kokungasebenzi kahle komjovo kunzima kakhulu kunakwezinye izinhlelo. Lapho enye yazo iqala ukusebenza ngokungalingani, abanye balungisa umsebenzi wabo ngendlela yokuthi bagcine ukuphuma kwamagesi e-exhaust ngaphakathi kwebanga elivamile.

Izinkinga ngokuqala imoto azikucasula nje kuphela, kodwa futhi bagcizelela ibhethri nesiqalisi. Nakuba ukushintshwa kwebhethri kungeyona inkinga, isiqalisi esiphukile sidinga ukulungiswa okumba eqolo. Okubi nakakhulu ngesikhwama semali kuzoba ukufaka esikhundleni se-dual-mass flywheel, eguga ngokushesha uma kufanele inxephezele ukushintshashintsha kwe-rpm. Futhi lokhu kumane kuyisiqalo sezinkinga ezingase ziphakame uma ungazinaki izimpawu zomjovo ohlulekile. Uhlu lwabo lude: ukulimala kwe-lambda probe, ukwehluleka kwesihlungi sezinhlayiya, ukungahambi kahle kweketango lesikhathi, futhi ezimweni ezimbi kakhulu, ngisho nokuncibilika kwamapiston.
