Isebenza kanjani injini ye-diesel?

Lona ukuphela kwepompo emaphethelweni esiteshi. Akekho obonakala engayisebenzisi. I-Lonely Island ayinalutho uze uzwe ukuduma kweloli. Iloli likhala lingena endaweni yokupaka bese likhuphukela endlini yokumpompa. Ongakuqapheli imoto ecwebile ekhasa ikhuphukela kolunye uhlangothi lwepompo. Udizili awusewona owamaloli kuphela.

Izinjini zikadizili bezisetshenziswa embonini yezokuthutha isikhathi eside. Bakhiqiza i-torque enkulu ngosayizi wabo futhi bathembekile ngaphansi kwemithwalo esindayo. Kodwa lobo buchwepheshe obugqame kakhulu emalolini buye bancishiswa ukuze balayishe amaloli nezimoto ezihlangene kube nemiphumela emihle, futhi ukuthandwa kwabo kuyakhula.

Iyini i-diesel fuel?

I-diesel fuel umqondo obanzi. Lokhu kubhekisela ohlotsheni lukaphethiloli oluvutha ngokucindezelwa esikhundleni senhlansi, olubizwa ngokuthi i-fuel ignition. Ivamise ukutholakala kuwoyela ongahluziwe, njengophethiloli, kodwa ibhekana nenqubo yokuhlanza ingxenye ehlukile. Lokhu kunikeza uphethiloli we-diesel izakhiwo ezinamafutha kakhulu kunophethiloli.

Eminye imithombo kadizili iye yathuthukiswa, njenge-biodiesel, engenziwa ngamafutha emifino. Uphethiloli wedizili kulula kakhulu ukuwugcina nokuyikhiqiza, futhi amakhithi asekhaya akuvumela ukuthi uzenzele owakho i-biodiesel.

Isebenza kanjani injini ye-diesel

Injini kadizili ihluke kakhulu kunekaphethiloli. Isisekelo siyafana, lapho ukuqhuma okuncane ngaphakathi kwesilinda senjini kuphushela i-piston phansi, okwenza i-stroke yamandla. Nokho, indlela lokhu okufinyelelwa ngayo ihluke ngokuphawulekayo.

Nakuba ukuqhuma kwenjini kaphethiloli kuvela ku-spark plug, izinjini zikadizili azibasi nhlobo. Awafakelwe ama-spark plugs futhi esikhundleni salokho athembele kuphela ekucindezelweni. Enjinini kaphethiloli, isilinganiso sokuminyanisa ngokuvamile siphakathi kuka-8:1 no-10:1, okusho ukuthi umthamo womoya nophethiloli kusilinda uminyaniswa ube ingxenye yesishiyagalombili noma ingxenye eyodwa kweziyishumi yevolumu yayo yoqobo. Enjinini kadizili, lokhu kucindezela kucishe kuphindwe kabili! Ingxube kaphethiloli wedizili nomoya ucindezelwa ukusuka ku-14:1 kuye ku-22:1.

Kungani ibalulekile? Lokhu kungenxa yokuthi ukuqhuma kumane nje kungenxa yokucindezela okukhulu kwalokhu kucindezelwa kuphethiloli. Uphethiloli wedizili awushi kahle uma ubhekene nenhlansi noma ilangabi, kodwa ukhiqiza amandla amakhulu uma uqhuma ngenxa yokucindezelwa.

umjovo wamafutha

Ngenxa yokuqina, ukungaguquguquki kwe-oyili, uphethiloli wedizili kunzima kakhulu ukuwenza i-athomu bese ufafaza kusilinda. Ngaphezu kwalokho, uphethiloli wedizili ujovwa endaweni ephakeme kakhulu yokucindezela. Lokhu kusho ukuthi uhlelo lomjovo lwenjini kadizili ludinga ingcindezi emangalisayo ukuze ujove uphethiloli kusilinda. Injini kadizili ivamise ukusebenza namaphampu kaphethiloli amabili; iphampu yokunikezela esuka ethangini ukuya endaweni yenjini kanye nepompo yomjovo womfutho ophezulu wokwandisa ingcindezi kuma-injection.

Izinzuzo zobuchwepheshe besimanje diesel

Ubuchwepheshe obusha emakethe, okuhlanganisa amasistimu omjovo ka-rail diesel (CRD) kanye nezihlungi zezinhlayiya zikadizili, kusho ukuthi izinjini zikadizili zisebenza ngokuthula futhi zihlanzekile kunangaphambili. Iphunga elibi nokusebenza okukhulu okwenza ubunikazi bedizili bungathandeki kwaqedwa, futhi inzuzo yomnotho kaphethiloli yandisa ukuthandwa kwayo futhi.

Izinkinga ezingaba khona nge-diesel fuel

Ukuba nemoto kadizili kungafika neqoqo lezinkinga ezijwayelekile. Uma usebenza ezindaweni ezibandayo namazinga okushisa angaphansi kweziro, uphethiloli wedizili uvamise ukuphenduka ijeli, okubangela izinkinga ezinkulu zokuqala nokusebenza. Lokhu kulula ukukunqanda nokukulungisa ngesifudumezi sika-diesel, kodwa kusacasula. Njengoba izinjini zikadizili zingadumile njengezinjini zikaphethiloli, ukuthola indawo yokugcwalisa ehlomele ukugcwalisa izimoto zabagibeli ngophethiloli wedizili ngezinye izikhathi kungaba nzima. Qaphela izindawo eziseduze, kanye namahora azo okuvula, futhi uhlele izitobhi zokufaka uphethiloli kusenesikhathi uma uhamba.

Izinkinga ezijwayelekile ngezinjini zikadizili

Amanzi awashi kahle. Lapho i-diesel fuel iqukethe umhwamuko wamanzi, ukusebenza kwawo kungathinteka kakhulu. Izinjini zikadizili zifakwe isisefo esibizwa ngokuthi isihlukanisi samanzi esidinga ukunakekelwa njalo futhi ngokuvamile asinakwa. Izinjini zikadizili zingabiza kakhulu ukuzikhanda ngoba zidinga umsebenzi omningi ukuzixilonga nokuzilungisa. Isibonelo senkinga evamile kubakhiqizi abaningi i-cylinder head gasket: ijwayele ukwehluleka ngaphambi kwesikhathi ngoba ivala iphuzu eliphakeme kakhulu lokucindezela enjinini. Ukugcinwa njalo ezitolo zokulungisa izimoto njenge-AvtoTachki, kanye nokuxilonga izinkinga njengoba zenzeka, kuzokusiza ugweme izikweletu zokulungisa ezingadingekile.
