2-stroke injini

Funda ukunyakaza oku-2-bar okuthathu

Isebenza kanjani?

Ingqwele yejubane, isiphambano, i-enduro ngisho nesilingo, injini enama-stroke ama-2 iyakwazi ukwenza konke. Ukwazi kanjani ukufeza lesi senzo? Kuleli sonto, Ukulungiswa Kwebhayisikili kukuphoqa ukuthi uthole amathumbu alo mbhemi oshisekayo kodwa ongalungiseki ukuze umqonde kangcono.

Le KTM enama-stroke amabili igcina amandla e-carburetor elula. Esikhathini esizayo esiseduze, uzofaka esikhundleni salo umjovo ohlanzeke kakhulu futhi osebenza kahle kakhulu.

Izinzuzo ze-2-stroke ekushiseni okukodwa ngakunye. Inzuzo enkulu ngaphezu kwe-4-stroke, eyivumela ukuthi inikeze amandla aphindwe kabili endaweni efanayo. Isici esikunikeza nokuguquguquka okukhethekile, okunenzuzo enkulu futhi kwaziwa ezivivinyweni. Njengoba ungabona ebhokisini lethu, imivimbo engu-2 yenza izinto ezi-2 ngesikhathi (ngaphezulu nangaphansi kwepiston), kodwa ngeshwa ixuba amabhulashi kancane. Eqinisweni, ivumela amagesi amasha ukuba ageleze ku-exhaust. Isici esiyenza ingcolise futhi idle kakhulu. Kodwa, njengoba sizobona kamuva, leli phutha alinqandeki, ikakhulukazi njengoba linezinye izimfanelo.

Elula futhi engasindi

Awekho ama-valve lapha, kodwa "ukukhanya" okuthole igama lesidlaliso "cylinder bore". Kuwukudlula kwepiston phambi kwezibani okuqinisekisa ukusatshalaliswa, ngaleyo ndlela kugwenywe ukusetshenziswa kwe-camshaft eyodwa noma ngaphezulu eshayelwa iketango elifakwe ama-tensioner, wonke ama-valve okulawula ngokusebenzisa imithambeka noma ama-tappets. Izingxenye eziyisipele eziholela ezindlekweni zokukhiqiza ezinciphe kakhulu kanye nokunakekelwa kanye nesisindo. Izimfanelo ezimenza abe ngumpetha wokuncintisana.

Injini yesikhathi esizayo!

Ngomjovo, othumela uphethiloli ku-cylinder kuphela ngemuva kokuba igesi yokukhipha ivaliwe, igesi yokukhipha ivinjelwa ekulahlekelweni igesi elisha. Ukungcola kanye nokusetshenziswa kuhlukaniswe ngu-2, kufinyelela emazingeni amanje ezinjini ezi-4-stroke ngenkathi zigcina izinzuzo zazo zemvelo. Lobu buchwepheshe busetshenziswa abakwa-Rotax kuma-twin-cylinders ayo angu-600 no-800 (isithombe), athuthukisa i-120 ne-163 hp. ku-8000 rpm, ngokulandelana. Noma yini esiyishoyo, ingxenye yesibili ayikabi nazwi layo lokugcina !!!

I-two-stroke inaleli gama ngoba yenza izigaba ezi-4 zomjikelezo wayo ... ngezinyathelo ezi-2. Ufeza lokhu ngokusebenza kanyekanye phezulu nangaphansi kwepiston. Ake sihlolisise ukuthi lokhu kusebenza kanjani.

Umfanekiso #1:

(Ngenhla kwepiston): Ukuphakamisa ipiston kucindezela ingxube. Lesi yisigaba sokucindezela.

(Ngezansi kwepiston): Ngesikhathi esifanayo, ukususwa kwepiston kukhulisa umthamo we-crankcase. Ngakho, ukucindezeleka kudonsa ingxube ngokusebenzisa ama-valve. Lesi yisigaba sokwamukela.

Umfanekiso #2:

(Ngenhla kwepiston): Ipiston isanda kufinyelela esiqongweni se-stroke yayo. Use-High Still, noma i-PMH. Inhlansi evela ku-spark plug ibangela ukuthi ingxube ivuthe bese ipiston iqala ukwehla. Lesi yisigaba somlilo.

(Ngezansi kwepiston): Ivolumu ye-crankcase isezingeni eliphezulu futhi umthamo uyaphela. Njengomthetho, zombili izikhathi zanamuhla zifakwe i-inlet ye-casing ephansi kanye nama-valve okuhlola, njengalapha, ukuvimbela ukukhishwa kwamagesi amasha asanda kutholwa.

Umfanekiso #3:

(Ngenhla kwepiston): Ukuvutha kwandisa ingcindezi nezinga lokushisa. Amagesi ayanda futhi ehlise i-piston. Lesi yisigaba sokushayela somjikelezo, esibizwa nangokuthi ukuphumula. Ngokushesha nje lapho ukukhanya okuphumayo kuvulwa (kwesobunxele), ingcindezi iyehla, ngaleyo ndlela ilungiselela ukungena kwamagesi amasha acindezelwe ngaphambili endlini ephansi.

(Ngaphansi kwepiston): Ivolumu ye-crankcase iyancipha, okubangela ukuthi ama-valve avale futhi amagesi amasha (aluhlaza) acindezelwe ngaphambili. Ukuvula izibani zokudlulisa kuzosusa amagesi amasha kusilinda. Kuyaphawuleka ukuthi ukukhanya okukhipha umoya ovulekile okubanzi kuvumela amanye amagesi ukuba aphume enjini ngaphandle kokuvutha. Ochwepheshe babiza lokhu "i-short circuit"
