Kedu ka mmanụ dizel si arụ ọrụ?

Isi ihe dị iche n'etiti injin dizel na injin mmanụ ụgbọ ala bụ na n'ime igwe mmanụ dizel, a na-eji mmanụ injector nozzles na-efesa mmanụ ahụ n'ime ụlọ ndị na-agba ọkụ naanị mgbe etinyere ikuku dị n'ọnụ ụlọ nke ọ bụla n'okpuru nnukwu nrụgide nke na ọ na-ekpo ọkụ nke ukwuu iji gbaa ọkụ. mmanụ ụgbọala ahụ ozugbo.
Nke a bụ nlele nzọụkwụ site na ihe na-eme mgbe ịmalite ụgbọ ala nwere mmanụ dizel.
1.Ị na-atụgharị igodo na mgbanye.
Mgbe ahụ, ị ​​na-eche ruo mgbe engine na-ewuli elu okpomọkụ zuru ezu na cylinders maka afọ ojuju mmalite.(Ọtụtụ ụgbọ ala nwere ntakịrị ọkụ nke na-ekwu "Chere," ma ụda kọmputa na-ekpo ọkụ nwere ike ịrụ otu ọrụ ahụ na ụfọdụ ụgbọ ala.) Ịtụgharị igodo na-amalite usoro nke a na-agbanye mmanụ n'ime cylinders n'okpuru nnukwu nrụgide nke na ọ na-ekpo ọkụ. ikuku na cylinders niile naanị ya.Oge ọ na-ewe iji kpoo ọkụ ebelatala nke ukwuu - ikekwe ọ ga-agafe 1.5 sekọnd na ihu igwe na-adịghị mma.
Mmanụ dizel adịghị agbanwe agbanwe karịa mmanụ ụgbọala ma dị mfe ịmalite ma ọ bụrụ na ụlọ ọkụ ahụ na-ekpo ọkụ, ya mere, ndị na-emepụta na-arụ ọrụ na-arụ ọrụ obere ọkụ na-arụ ọrụ na batrị iji kpoo ikuku na cylinders mgbe mbụ ị malitere engine.Usoro nchịkwa mmanụ ọkụ ka mma na nrụgide injection dị elu na-emepụta ọkụ zuru oke iji metụ mmanụ ọkụ na-enweghị ọkụ ọkụ, ma plọg ahụ ka dị n'ebe ahụ maka njikwa ikuku: Okpomọkụ ọzọ ha na-enye na-enyere aka ọkụ ọkụ nke ọma.Ụgbọ ala ụfọdụ ka nwere ụlọ ndị a, ndị ọzọ enweghị, mana nsonaazụ ya ka bụ otu.
2. "Malite" ọkụ na-aga.
Mgbe ị hụrụ ya, ị ga-azọ ụkwụ na ngwa osooso wee tụgharịa igodo mgbanye ka ọ bụrụ “Malite.”
3.Fuel nfuli na-anapụta mmanụ ụgbọala si tank tank na engine.
Ka ọ na-aga, mmanụ ọkụ ahụ na-agafe n'ime ihe nzacha mmanụ ụgbọala na-ehicha ya tupu ya erute n'oghere injector mmanụ ụgbọala.Idozi ihe nzacha kwesịrị ekwesị dị mkpa na mmanụ dizel n'ihi na mmetọ mmanụ ụgbọala nwere ike mechie obere oghere ndị dị na nozzles injector.

4.The mmanụ ụgbọala injection mgbapụta pressurizes mmanụ ụgbọala n'ime a nnyefe tube.
A na-akpọ tube nnyefe a ụgbọ okporo ígwè ma na-edebe ya n'ebe ahụ n'okpuru nrụgide dị elu mgbe niile nke 23,500 pound kwa square inch (psi) ma ọ bụ karịa ka ọ na-ebuga mmanụ ụgbọala na cylinder ọ bụla n'oge kwesịrị ekwesị.(Nrụgide mmanụ ụgbọala nwere ike ịbụ naanị 10 ruo 50 psi!) Ndị na-emepụta mmanụ ọkụ na-enye mmanụ ọkụ dị ka ezigbo ịgbasa n'ime ụlọ combustion nke cylinders site na nozzles na-achịkwa nke engine's engine control unit (ECU), nke na-ekpebi nrụgide, mgbe mmanụ ọkụ na-eme, ogologo oge ọ na-adị, na ọrụ ndị ọzọ.
Igwe mmanụ dizel ndị ọzọ na-eji hydraulics, wafers crystalline, na ụzọ ndị ọzọ iji chịkwaa ntụtụ mmanụ, a na-emepụtakwa ihe ndị ọzọ iji mepụta engine mmanụ dizel nke na-adị ike karị ma na-anabata ya.
5.The mmanụ ụgbọala, ikuku, na "ọkụ" izute na cylinders.
Ọ bụ ezie na nzọụkwụ ndị bu ụzọ na-enweta mmanụ ọkụ n'ebe ọ kwesịrị ịga, usoro ọzọ na-aga n'otu oge iji nweta ikuku ebe ọ kwesịrị ịdị maka egwuregwu ikpeazụ, ọkụ ọkụ.
Na mmanụ dizel ndị a na-emekarị, ikuku na-esi n'ihe na-ehicha ikuku na-abata bụ́ nke yiri nke dị n'ụgbọ ala ndị na-enye gas.Agbanyeghị, turbochargers ọgbara ọhụrụ nwere ike ibuba oke ikuku n'ime cylinders ma nwee ike inye ike na akụ na ụba mmanụ ọkụ n'okpuru ọnọdụ kacha mma.Turbocharger nwere ike ịbawanye ike na ụgbọ ala diesel site na pasent 50 ebe ọ na-ebelata oriri mmanụ ya site na pasent 20 ruo 25.
6.Combustion na-agbasa site na obere mmanụ ọkụ nke a na-etinye n'okpuru nrụgide na ụlọ precombustion na mmanụ ọkụ na ikuku n'ime ụlọ ọkụ n'onwe ya.
