Ga n'ihu nke usoro maka draịva nkeji nke ika

N'oge a, ndị na-emepụta mmanụ ụgbọala nke oge a na-achọ ụzọ dịgasị iche iche iji mee ka arụmọrụ ha dịkwuo elu. Ọ bụ ezie na mmanụ dizel n'afọ ndị na-adịbeghị anya enwewokwa mbelata site na mbelata nke mbugharị, mmụba nke nrụgide na usoro injection, na mgbe ụfọdụ site na iji usoro turbocharging cascade. Agbanyeghị, ha ejirila ndochi mmanye ogologo oge na, n'adịghị ka ndị ogbo ha mmanụ ụgbọ ala, ahapụlarị usoro mgbanwe mgbanwe site na ikuku gaa na njuputa mmanye. Ụkpụrụ nke ịrụ ọrụ nke dizel nwere nrụgide dị elu na cylinders na enweghị valvụ trotul na-eme ka ha dị mma na mbụ. Ya mere, mbelata nke engines mmanụ ụgbọala na-ewere àgwà dị oke egwu na mbelata olu na ọnụ ọgụgụ nke cylinders na mgbanwe gaa na njuputa mmanye. Otú ọ dị, okpomọkụ dị elu nke gas na-ekpocha ọkụ ma e jiri ya tụnyere diesel ka na-eme ka ojiji nke geometry turbochargers na-agbanwe agbanwe (ma e wezụga BorgWarner nkeji maka Porsche 911 Turbo), valvụ trotul na-aga n'ihu na-emepụta nguzogide ikuku, na ndị na-emepụta na-achọ ihe niile. ụzọ ndị ọzọ enwere ike iji melite arụmọrụ ha. Afọ iri gara aga, Audi mbụ ẹkenam Nchikota turbocharging na kpọmkwem mmanụ ụgbọala injection na ya TFSI, na ugbu a na ya ọhụrụ 2.0 TFSI unit, ụlọ ọrụ injinia alaghachila nke ọma Miller okirikiri - naanị na a kama gbanwetụrụ ụdị. Ahịa ụlọ ọrụ na-akpọ nkà ihe ọmụma okike nke moto ọhụrụ na ike nke 190 hp. na oke torque nke 320 Nm "rightsizing", n'echiche nke "olu ọrụ ahọpụtara nke ọma". Otú ọ dị, okwu ahụ dị nnọọ iche na ozi nke ndị ọrụ ibe ha si Mazda, bụ ndị na-ezo aka na nke a iji zere njuputa mmanye.

N'aka ozo, na Audi, turbocharging bu ihe di nkpa n'ime usoro oru ohuru nke injin ohuru, dika onye compressor bu ihe na-adighi agbanwe agbanwe nke injin igwe Miller, nke kachasi bu Mazda Millenia nke 90s. Principlekpụrụ ọrụ a na-agụnye idebe valvụ ahụ na-emeghe ogologo oge mgbe piston amalitela ịkwaga site na ala gaa na etiti nwụrụ anwụ. Ka ikuku si otú a na-amalite ịlaghachi na ihe ngosi oriri, igwe na-arụ ọrụ igwe, nke na-emepụta nrụgide azụ, na-elekọta njide ya.

N'aka nke ọzọ, ogo ọgbụgba mgbasa na-adị elu karịa ogo mkpakọ na-enweghị ihe egwu nke mgbawa. Nke ahụ bụ, ụkpụrụ Miller na-enye ohere ịnweta mkpakọ na mmụba dị iche iche, karịa otu ihe ahụ na ọkọlọtọ Otto engine. Mmetụta dị mma bụkwa ikike iji rụọ ọrụ na valvụ mepere emepe sara mbara.

Nkọwa nke Audi banyere usoro Miller

Ndị na-emepụta Audi na-akọwa isiokwu a n'ụzọ nke ha. N'adịghị ka usoro bụ isi, Otú ọ dị, kama ijide valvụ oriri na-emeghe iji belata mkpakọ mkpakọ, ha na-emechi ya nke ọma na mbụ - tupu piston erutela ebe etiti nwụrụ anwụ. Kama oge mmeghe bụ ogo 190-200 nke ntụgharị crankshaft dị ka ọ dị na mbụ, valvụ ahụ na-emeghe naanị ogo 140. Agbanyeghị, na omume, nke a na-enweta otu mmetụta ahụ nke ibelata oke mkpakọ. A na-akwụ ụgwọ maka oge mmeghe na-ebelata site n'ịbawanye nrụgide nkwalite site na iji turbocharger. N'ihi ya, engine na-enweta ihe oriri nke engine na-ebelata, ma na-arụ ọrụ zuru ezu na-arụ ọrụ ike nke nnukwu igwe. N'ime ọrụ ibu nke akụkụ, a na-eme ntinye mmanụ ọkụ ọzọ na strok dị elu nke piston site na iji usoro injection ozugbo, nke na-emeju usoro ịgbanye ọzọ n'ime ọtụtụ ihe oriri. Tụkwasị na nke ahụ, Audi Valvelift System (AVS) maka oge valvụ na-agbanwe agbanwe na-enye ohere ka oghere mmeghe nke valvụ ndị na-eri ihe na-abawanye ruo ogo 170 n'okpuru ibu zuru oke. Agbakwunyere na nke a bụ njikwa nju oyi nwere ọgụgụ isi, ọtụtụ ihe na-ekpochapụ isi na mbelata esemokwu site na iji mmanụ viscosity dị ala (0W-20). N'ihi ọtụtụ ngwọta teknụzụ dị elu, 2.0 TFSI ọhụrụ nwere oke torque na oke nke 1450 ruo 4400 rpm ma na-eri obere mmanụ.

3.0 TFSI: Nhazi igwe kama turbocharger

Ndị ọrụ Porsche họọrọ biturbo ndochi maka ya liter atọ V6 engine na 420 hp. Maka 3.0 TFSI, Audi na-eji igwe eji arụ ọrụ (Eaton nke isii, R1320) na ikuku mmiri / ikuku. Usoro nke imepụta injin ahụ dị mkpụmkpụ, nke nwere ike ịbụ otu n'ime nkọwa maka mkpebi a, ọ bụ ezie na Audi na-ekwu na echiche a kachasị mma n'ihi uru ndị ọzọ - dị ka ewu ewu nke ụdị mmanye a na-amanye na United States. Ihe a kapịrị ọnụ nke azịza Audi gụnyere compressor dị n'azụ valvụ ahụ, nke na-eme ka arụmọrụ juputara. Na ele mmadụ anya n'ihu, valvụ pụrụ iche na ụlọ compressor na-eweghachi ụfọdụ ikuku jikọtara ọnụ na ntinye ya, si otú a na-ebelata mfu na ike achọrọ iji gbanwee ya. Na omume, ruo n'ụdị ụfọdụ, otu ahụ na-arụ ọrụ nke ọma dịka igwe ikuku na naanị na nnukwu ibu ka Compressor na-amalite ịrụ ọrụ na ike ya niile.

2.5 TFSI: Sịlịnda ise maka ụdị kọmpi egwuregwu

Nke a unit na-eso ọtụtụ n'ime postulates nke ụlọ ọrụ ndị ọzọ engines, na-ewere n'ime akaụntụ kpọmkwem nke ise-cylinder engines. 2.5 TFSI, Otú ọ dị, nwere oke ngwa ngwa na naanị ụdị ike dị ka Audi RS 3, TT RS na RS Q3. Na Audi TT RS gbakwunyere ụdị, engine nwere ntughari nke 2,48 lita nwere ike nke 360 ​​hp. – dị ka AMG ọhụrụ engine anọ-cylinder maka A-Class na ya mmepụta. Otú ọ dị, engine nke ise cylinder na-enye ya kacha torque nke 465 Nm budata na mbụ (na nso 1650 ka 5400 rpm) karịa igwe nke ndị ọrụ ibe si Stuttgart.
