Indlela injini yomjovo isebenza ngayo, isimiso sokusebenza kanye nezinzuzo

Esikhundleni sezinjini ze-carbureted ezisanda kutholakala yonke indawo, izinjini zokujova noma zokujova manje sezisetshenziswa kakhulu. Isimiso sokusebenza kwazo silula futhi siyonga ngokwedlulele. Nokho, ukuze baqonde inzuzo injector, kufanele uqale uqonde ukuthi kungani esikhundleni carburetors.

I-carburetor isebenzela ukuhlinzeka ngophethiloli endaweni eningi yokungena, lapho isivele ixubene nomoya, futhi ukusuka lapho isakazwa emakamelweni avuthayo ama-pistons. Ukunikezwa nokuxutshwa kukaphethiloli nomoya kuzodla amandla enjini - afinyelela kumaphesenti ayishumi. Uphethiloli udonswa ezinhlobonhlobo ngenxa yomehluko wengcindezi emkhathini nasezindaweni eziningi, futhi ukuze kugcinwe izinga lokucindezela elifunekayo, kusetshenziswa izinsiza zenjini.

Ngaphezu kwalokho, i-carburetor inezinye izinto eziningi ezimbi, isibonelo, lapho uphethiloli omningi udlula ku-carburetor, umane awunaso isikhathi sokuqondisa ngentamo ewumngcingo ku-manifold, ngenxa yalokho i-carburetor iqala. ukubhema. Uma uphethiloli ungaphansi kwezinga elithile, injini imane nje ayidonsi futhi igcine - isimo esijwayelekile kwabaningi.

Isebenza kanjani i-injector

I-injector, empeleni, yenza umsebenzi ofanayo enjini njenge-carburetor - inikeza uphethiloli emakamelweni omlilo we-pistons. Nokho, lokhu akubangelwa ukumuncwa kukaphethiloli ezinhlobonhlobo eziningi, kodwa ngokujova uphethiloli ngemibhobho ngokuqondile emakamelweni avuthayo noma kumanifold, futhi lapha uphethiloli uxutshwa nomoya.

Amandla ezinjini zokujova ngokwesilinganiso aphezulu ngamaphesenti ayi-10 kunalawo ezinjini ze-carburetor.

Ama-injection ahlukaniswe abe izinhlobo ezimbili eziyinhloko:

i-mono-injection - uphethiloli unikezwa ngemibhobho ku-manifold, bese usakazwa ngqo emakamelweni omlilo;
umjovo osakazwayo - ekhanda le-cylinder kukhona i-nozzle ye-piston ngayinye futhi ingxube ye-fuel-air kwenzeka ekamelweni elivuthayo.

Izinjini zokujova ezinomjovo osabalalisiwe zizonga kakhulu futhi zinamandla. Uphethiloli uhlinzekwa lapho i-valve yokungena ivuleka.

Isebenza kanjani injini yomjovo, isimiso sokusebenza kanye nezinzuzo

Izinzuzo ze-injector

Uhlelo lomjovo luphendula ngokushesha kunoma yiluphi ushintsho ekulayisheni injini, ngokushesha nje lapho isivinini sikhuphuka, umjovo wenziwa njalo.

Izimoto ezinesistimu yomjovo kulula ukuziqala, umzuzu oshukumisayo wenjini uyakhula. I-injector isabela kancane ezimweni zezulu, ayidingi ukufudumeza isikhathi eside emazingeni okushisa omoya angaphansi kweqanda.

Ama-injection "anobungane" kakhulu emvelweni, izinga lokukhishwa kwezinto eziyingozi liphansi ngamaphesenti angama-50-70 kunalelo le-carburetor.

Futhi ayonga kakhulu, njengoba uphethiloli usetshenziswa ngendlela edingekayo ukuze injini isebenze kahle okwamanje.

Ukubi kwezinhlelo zokujova

Ukungalungi kuhlanganisa iqiniso lokuthi ukusebenza okujwayelekile kwenjini kudinga umsebenzi odidiyelwe wezinzwa eziningana ze-elekthronikhi ezilawula imingcele ehlukene futhi zizidlulisele kumprosesa oyinhloko wekhompiyutha ebhodini.

Izidingo eziphakeme zokuhlanzeka kukaphethiloli - izintamo ezincane zama-injection zizovala ngokushesha uma kusetshenziswa uphethiloli wekhwalithi ephansi.

Ukulungisa kubiza kakhulu, futhi ezinye izakhi azikwazi ukubuyiselwa sanhlobo.

Njengoba ubona, akukho uhlelo olulodwa olungenazo izinkinga, noma kunjalo, i-injector inezinzuzo eziningi, futhi kungenxa yalokhu ukuthi izinjini zokujova zeza ukuzothatha indawo ye-carburetor.

Ividiyo ebonakalayo kakhulu, ku-3D, mayelana nomgomo wokusebenza kwenjini yomjovo.
