A na-enweta usoro nke injin diesel na-agbanwe ike okpomọkụ ka ọ bụrụ ike nrụpụta site na usoro anọ na-aga n'ihu: oriri, mkpakọ, ọrụ na iyuzucha. A na-akpọ usoro ọ bụla dị otú ahụ okirikiri ọrụ. A na-akpọ injin ọ bụla mezuru okirikiri ọrụ site n'ịtụgharị crankshaft ugboro abụọ ma na-emegharị piston ugboro anọ ka a na-akpọ injin strok anọ. Ụkpụrụ na-arụ ọrụ nke engine diesel nwere ọrịa strok anọ:

1. ịṅụ ọgwụ ike

Oghere crankshaft na-ebugharị piston ka ọ si n'etiti etiti nwụrụ anwụ gaa na etiti nwụrụ anwụ. N'oge a, valvụ oriri na-emeghe ma mechie valvụ ikuku. N'oge mmegharị nke piston ahụ, olu cylinder ahụ ji nwayọọ nwayọọ na-abawanye, na-eme oghere, ya mere a na-agbanye ngwakọta combustible n'ime cylinder site na valvụ oriri ruo mgbe piston rutere n'etiti etiti nwụrụ anwụ ma mechie valvụ oriri.

N'ihi nkwụsị nke oriri nke usoro oriri, nrụgide nke gas na cylinder na njedebe nke oriri bụ ala karịa ikuku ikuku, banyere 0.075MPa ~ 0.09MPa. N'ihi ikpo ọkụ nke akụkụ okpomọkụ dị elu dị ka mgbidi cylinder na piston na ikuku ọkụ na-ekpo ọkụ na-ahapụ na okirikiri gara aga, okpomọkụ gas na-ebili na 370K ~ 440K. Ihe na-abanye na cylinder n'oge ọrịa strok oriri abụghị ngwakọta ọkụ, kama ikuku dị ọcha.

2. mkpakọ ọrịa strok

Na njedebe nke ọrịa strok oriri, piston na-esi na etiti nwụrụ anwụ gaa n'elu ebe anwụ anwụ nke crankshaft na-ebugharị, na ụda cylinder na-eji nwayọọ nwayọọ na-ebelata. N'oge a, a na-emechi valvụ ndị na-eri nri na ikpochapụ, na ikuku dị ọcha na-agbanye. Mkpakọ ahụ na-akwụsị mgbe piston rutere n'etiti etiti nwụrụ anwụ. N'oge usoro mkpakọ, nrụgide gas na okpomọkụ na-abawanye n'otu oge ahụ, a na-ejikọtakwa ngwakọta ahụ n'ihu. Ebe ọ bụ na oke mkpakọ nke dizel buru ibu, ihe dị ka 15 ruo 22, okpomọkụ na nrụgide na njedebe nke mkpakọ dị oke elu, nrụgide nwere ike iru 3MPa na 5MPa, na okpomọkụ nwere ike iru 800K ruo 1000K.

3. strok ike

Na njedebe nke mkpakọ strok, mmanụ ọkụ injection mgbapụta na-efesa mmanụ dizel dị elu n'ime okpomọkụ dị elu na ikuku dị elu na cylinder site na injector n'ụdị alụlụ, nke na-agbapụta ngwa ngwa ma mepụta ngwakọta na ikuku. Ebe ọ bụ na okpomọkụ dị na cylinder dị elu karịa ọkụ ọkụ diesel nke akpaaka (ihe dị ka 500K), ngwakọta mmanụ dizel ozugbo na-ere ọkụ ma na-ere ọkụ n'onwe ya, na ruo oge ụfọdụ mgbe nke ahụ gasịrị, nrụgide na okpomọkụ dị na cylinder na-ebili nke ọma mgbe a na-agba ya. mmanụ ụgbọala, ịkwanye piston ala ka ọ rụọ ọrụ. N'oge ike strok, ozugbo nrụgide nwere ike iru 5MPa ~ 10MPa, na ozugbo okpomọkụ nwere ike iru 1800K ~ 2200K.

4. Ọnwụ strok

Mgbe strok ike dị nso na njedebe, valvụ ikuku na-emepe emepe, valvụ ihe oriri na-emechi, na crankshaft na-ebugharị piston site na etiti nwụrụ anwụ ruo n'elu ebe nwụrụ anwụ site na mkpanaka njikọ. A na-ewepụ gas na-ekpocha ọkụ na cylinder n'okpuru nrụgide nke ya na ntinye nke piston. Mgbe piston rutere n'elu etiti nwụrụ anwụ, valvụ ikuku na-emechi na iyuzucha ya kwụsịrị. N'ihi na e nwere nkwụsi ike iyuzucha na iyuzucha usoro, na njedebe nke iyuzucha ọrịa strok, nrụgide na cylinder dịtụ elu karịa ikuku ikuku, banyere 0.105MPa ~ 0.115MPa, na okpomọkụ bụ banyere 900K ~ 1200K.

N'ime strok anọ ahụ, ọ bụ naanị strok ike na-emepụta ike, na strok atọ ndị ọzọ bụ strok inyeaka iji kwadebe maka strok ike, ha niile na-erikwa ume. Na okirikiri nke mbụ mgbe injin na-amalite, a ga-enwerịrị ike mpụga iji tụgharịa crankshaft iji mezue oriri na mkpakọ strok. Mgbe strok ike malitere, a na-echekwa ike na-arụ ọrụ na flywheel site na crankshaft iji nọgide na-aga n'ihu nke okirikiri ndị na-esote.
