I-Turbocompound - kuyini? Isimiso sokusebenza

Ukwenza ngcono ukusebenza kahle kwamayunithi kagesi, abakhiqizi bakha izindlela nezinsiza ezahlukahlukene. Phakathi kwazo kukhona i-turbocompound. Ake sibheke ukuthi hlobo luni lwedivayisi, ukuthi isebenza kanjani i-turbocompound engine nokuthi yiziphi izinzuzo zayo.

Yini i-turbocompound

Lokhu ukuguqulwa isetshenziswa injini udizili. Ngendlela yakudala, injini ine-turbine esebenzisa amagesi e-exhaust ukukhulisa umfutho womoya kokuphindaphindwayo kokudla.

I-turbine yegesi inikeza ukushisa okungcono kwe-HTS kumasilinda, ngenxa yokuthi umkhathi uthola izinto ezingeyona ingozi kangako, futhi injini ithola amandla akhuphukayo. Kodwa-ke, le ndlela isebenzisa kuphela ingxenyana yamandla akhishwe lapho amagesi e-exhaust eshiya inqwaba ye-exhaust.

Nazi ezinye izinombolo. Ukushisa kwegesi okukhipha lapho kuphuma enjinini kungafinyelela kuma-degree angama-750. Njengoba igesi idlula ephepheni, iyaphotha ama-blades, okunikeza imoto inani elengeziwe lomoya omusha. Lapho kuphuma i-turbine, amagesi asashisa (izinga lawo lokushisa lehla ngama-degree ayikhulu kuphela).

Amandla asele asetshenziswa ngebhulokhi ekhethekile lapho kuqhuma khona. Idivayisi iguqula la mandla abe isenzo sokusebenza, okwandisa ukujikeleza kwe-crankshaft.

Ukuqokwa

Ingqikithi yebhlokhi eyinhlanganisela ukukhulisa amandla e-crankshaft ngenxa yamandla avele asuswe angene emoyeni ngenjini ejwayelekile. Udizili uthola umfutho owengeziwe, kodwa awusebenzisi uphethiloli owengeziwe.

Isebenza kanjani i-turbo compound

Turbocharging Classic siqukethe izindlela ezimbili. Owokuqala yigesi, impeller yayo iqala ukusebenza ngenxa yokuthi ingcindezi idalwa kupheshana lokukhipha. Umshini wesibili yi-compressor ehambisana nento yokuqala. Inhloso yawo ukupompa umoya ohlanzekile kumasilinda.

Enhliziyweni yeyunithi eyengeziwe, i-turbine yamandla isetshenziswa, engemuva kweyinhloko. Ukuqeda umehluko omkhulu phakathi kokujikeleza kwe-turbo compound ne-flywheel, isici se-hydraulic sisetshenziswa - i-clutch. Ukushibilika kwayo kuqinisekisa ukufaniswa kwetorque ephuma kudivayisi nakuma-crankshaft enjini.

Nayi ividiyo emfushane yokuthi enye yezinguquko zezinjini zeVolvo turbocompound isebenza kanjani:

Isikimu sokusebenza se-Turbo compound

Nawu umdwebo osheshayo wendlela esebenza ngayo injini ye-turbo. Okokuqala, ugesi wokukhipha ungena emgodini we-turbocharger, uzungeza i-turbine enkulu. Ngaphezu kwalokho, ukugeleza kuzungezisa impeller yale ndlela. Ngaphezu kwalokho, ijubane lingafinyelela ezinkulungwaneni eziyikhulu ngomzuzu.

Ibhulokhi elihlanganisiwe lifakwe ngemuva kwesekethe enkulu kakhulu. Umfudlana ungena emgodini wawo, uzungeze i-turbine yawo. Lesi sibalo sifinyelela ezinkulungwaneni ezingama-55 ngomzuzu. Ngaphezu kwalokho, kusetshenziswa ukuhlanganiswa koketshezi kanye negiya lokunciphisa elixhunywe ku-crankshaft. Ngaphandle kokuhlanganiswa oketshezi, idivayisi ngeke ikwazi ukunikeza ukwanda okushelelayo kwamandla enjini yomlilo yangaphakathi.

Injini ye-scania inohlelo olunjalo. Le nqubo ingumsebenzi wesikhungo samandla i-DT 1202. Injini yakudala kadizili eyayine-turbocharged yakwazi ukuthuthukisa amandla ngaphakathi kuka-420hp. Ngemuva kokuthi umkhiqizi athuthukise amandla kagesi ngohlelo lwe-turbo compound, ukusebenza kwawo kukhuphuke ngamahhashi angama-50.

Izinzuzo nokungalungi

Ukubonakala kokuthuthukiswa okusha kwenza kube nokwenzeka ukufeza le miphumela emihle elandelayo:

• Ukwanda okuhloniphekile kokusebenza kahle kwenjini, kepha ngasikhathi sinye i-crankshaft ayijiki ngaphezu kokujwayelekile;
• Ngesikhathi sokusebenza, ukufakwa akudingi uphethiloli owengeziwe, okwenza imoto ingabi namandla ngokwengeziwe;
• Ngenxa yobukhona be-hydraulic coupling, ukuzinza kweyunithi kuqinisekiswa ngoshintsho olubukhali kumthwalo;
• Injini isebenza ngokushelela kakhulu ngoba ukwanda kwamandla kuhlinzekwa ngokushintshana okusebenzayo kwe-crankshaft, kepha hhayi ngenxa yamajolti avela kumshini we-crank;
• Ukuqina kweyunithi akwehli, sengathi kufakwe i-turbine enjinini ejwayelekile. Ngokuphambene nalokho, ngenxa yokwehliswa kwemishini ye-piston, insiza yayo yokusebenza iyanda.

Okubi kubandakanya iqiniso lokuthi kwasetshenziswa imali eningi entuthukweni nasekufakweni okungeziwe kuzodinga nokukhokhelwa kwesimanje sezinjini. Ngaphezu kwezindleko eziphakeme zenjini uqobo, ukwakheka kwayo kuya kuba nzima. Ngenxa yalokhu, ukugcinwa futhi, uma kunesidingo, ukulungiswa kubiza kakhulu, futhi inkosi eyiqonda kahle le nto yokufaka kunzima kakhulu ukuyithola.
