Injini Yokucindezela Eguquguqukayo / Ukusebenza Kwenjini Yokucindezela Okuguquguqukayo

Yethulwe ngabakwa-Infiniti, kodwa isikhathi eside icatshangwa abanye abakhiqizi abaningi, injini yokucindezela eguquguqukayo isiyatholakala emakethe yezimoto.

Ukucindezela?

Okokuqala, kubalulekile ukwazi ukuthi iyini isilinganiso isilinganiso injini. Lobu ubudlelwano obulula phakathi komthamo womoya ongacindezelwanga (lapho ipiston iphansi: indawo ephansi efile) nalapho icindezelwa (lapho ipiston iphezulu: isikhungo esiphezulu esifile). Lesi sivinini asishintshi, ngoba indawo ye-piston ngaphansi noma phezulu ihlala ifana, ngakho-ke ama-roundabouts asuka endaweni A (PMB) aye ku-B (PMH).

Kule V-engine yakudala, sibona i-TDC ne-PMA ngesikhathi esisodwa. Umoya ocindezelwe kwesokunxele kanye nomoya ongacindezelwe kwesokudla

PMB: ipiston phansi

TDC: ipiston iphezulu

Inzuzo yesilinganiso sokucindezela okuphezulu?

Qaphela ukuthi uma ukhulisa isilinganiso sokucindezela, ukhulisa ukusebenza kahle kwenjini, ngakho amandla ayancipha. Ngakho-ke, umgomo wabaklami ukuwuphakamisa phezulu ngangokunokwenzeka. Kodwa-ke, kunengqondo ukuthi ukucindezela okukhulu, umthwalo omkhulu wezakhi zemishini, ngakho-ke kufanele kuqashelwe ukuthi ungadluli. Ngaphezu kwalokho, ukucindezela igesi kukhulisa izinga lokushisa layo, okuyisimiso esingokomzimba sezinjini zikadizili. Esigabeni esithile, uma sicindezela uphethiloli kakhulu kugesi (ngakho-ke umoya), izinga lokushisa liyoba phezulu kangangokuthi uphethiloli uzovutha wodwa ngisho nangaphambi kokuba ikhandlela liwushise... Khona-ke ukuthungela kuzokwenzeka maduze. , okubangela ukulimala kumasilinda (kodwa nama-valve) futhi kubangele ukungqongqoza.

Into yokungqongqoza izoqina ngenani elikhulu likaphethiloli, okungukuthi, lapho ulayisha (lapho ucindezela kakhulu i-pedal, kulapho kujovwa khona uphethiloli owengeziwe).

Esimeni esinjalo, kungaba kuhle ukuba nesilinganiso sokucindezelwa okuphezulu ekulayisheni okuphansi kanye nesilinganiso "esihlehlisayo" kancane uma sicindezelwa kanzima.

Isilinganiso Sokucindezela Okuguquguqukayo: Kodwa Kanjani?

Ukwazi ukuthi isilinganiso sokucindezela sincike ekuphakameni lapho i-piston ingahamba khona (TDC), ngakho-ke kwanele ukukwazi ukushintsha ubude bezintambo zokuxhuma (lezi "izinduku" ezibamba ama-piston futhi zixhuma crankshaft). Isistimu, eyasungulwa i-Infiniti, ngakho-ke ishintsha lokhu kuphakama ngenxa yesistimu ye-electromagnetic, ukuze ama-crank manje anganwetshwa! Izilinganiso ezimbili ezingenzeka zibe sezishintshwa zisuka ku-8: 1 ziye ku-14: 1, emva kwalokho ingxube yegesi / uphethiloli ingacindezelwa izikhathi eziyi-8 noma eziyi-14, okwenza umehluko omkhulu!

Sikhuluma nge-crankshaft ehambayo, ongoti bazosheshe babone ukuthi ayibukeki njengalokhu esijwayele ukukubona.

Lokhu kuphambene nenjini evamile, izinduku zayo zokuxhuma ziyizintambo ezilula ezixhunywe ku-crankshaft.

Nawa amalebula amabili i-Infiniti ewaqoke ukuthi amele ama-TDC amabili angaba khona.

Ngomthwalo ophansi isilinganiso sizoba sezingeni eliphezulu, okungukuthi, 14: 1, kuyilapho ngomthwalo omkhulu sizokwehla siye ku-8: 1 ukugwema ukuvutha okuzenzakalelayo ngaphambi kokuba i-spark plug yenze umsebenzi wayo. Ngakho-ke kufanele silindele ukubona ukonga uma unonyawo olulula, ukushayela kwezemidlalo ekugcineni akushintshi njengoba ukucindezela kuba "okuvamile" futhi. Kusazobonakala ukuthi lolu hlobo lwe-crank ehambayo luzothembeka ngokuhamba kwesikhathi, ngoba ukwengeza izingxenye ezihambayo kuhlale kuyingozi ...

Sawubona, Ngiyabonga ngazo zonke izihloko zenu ezichazwe kahle kakhulu futhi zangifundisa okuningi. Uma ngiqonda kahle, izinjini zikaphethiloli manje sezifakwe umjovo oqondile, njengodizili. Pho kungani siqhubeka "nokulawula" isilinganiso sokucindezela ukuze sinqande ukuzithungela lapho umoya ocindezelwe ungenawo uphethiloli? Il J. 5 ukusabela (kula) mazwana: Enkidu (2017-10-17 21:18:18): Kuhlala kubuhlungu ukuthi i-athikili ibhalwa ngaphandle kolwazi lwesihloko. Injini yokucindezela eguquguqukayo isebenza ngesiFulentshi ngisho ne-"ardà © chois"! Izilokotho ezinhle kini nonke. sergio57 (2018-06-04 09:57:29): Sanibonani nonke, ngisho nokunye: Unjiniyela we-Metz National School 1983 UMnu J.

Jesse (2021-10-11 17:08:53): Mayelana nalokhu, ukhuluma ngokuthi isilinganiso sokucindezela singakhuphuka kanjani sisuka ku-8: 1 siye ku-14: 1 sibonga uhlelo. Kwenzeka kanjani ukuthi ukwehlisa isilinganiso sokucindezela (sehle siye ku-8: 1) kunikeza amandla engeziwe? Akuyona yini enye indlela? Ngikhumbula ukuthi emncintiswaneni senze umsebenzi omncane ezingxenyeni zenjini ukuze sikwazi ukukhuphula isilinganiso sokucindezela ngaleyo ndlela sandise amandla enjini. Ukuphakama kwesilinganiso sokucindezela, i-piston stroke iba yinde futhi ngenxa yalokho iba nkulu isilinganiso se-oxidizer / injected fuel ratio, yingakho kuba ngcono ukusebenza kahle kanjalo namandla alethwayo, akunjalo? (Okuthunyelwe kwakho kuzobonakala ngaphansi kwamazwana)
