2-stroke injini

Phunzirani 2-bar mayendedwe atatu

Kodi ntchito?

Champion wa liwiro, mtanda, enduro ngakhale mayesero, 2-sitiroko injini amadziwa kuchita izo zonse. Kodi amakwanitsa bwanji kuchita zimenezi? Sabata ino, Kukonza Biker kumakukakamizani kuti mupeze matumbo a munthu wosuta koma wosasinthika kuti mumumvetse bwino.

KTM yokhala ndi mikwingwirima iwiri iyi imapangitsa mphamvu ya carburetor kukhala yosavuta. Posachedwapa, adzalowa m'malo mwake ndi jekeseni yoyeretsa kwambiri komanso yogwira mtima kwambiri.

Sitiroko 2 imapindula ndi kuyaka kumodzi pa sitiroko. Ubwino waukulu kuposa 4-sitiroko, yomwe imalola kuti ipereke mphamvu kuwirikiza kawiri pa kusamutsidwa komweko. Mbali yomwe imapatsanso kusinthasintha kwapadera, yopindulitsa kwambiri komanso yodziwika pamayesero. Monga mukuonera m'bokosi lathu, zikwapu za 2 zimapanga zinthu za 2 panthawi (pamwamba ndi pansi pa pistoni), koma mwatsoka zimasakaniza maburashi pang'ono. Ndipotu, amalola mpweya watsopano kulowa mu utsi. Chilema chomwe chimapangitsa kuipitsa ndikuwononga kwambiri. Koma, monga momwe tidzaonera m’tsogolomu, chilema chimenechi sichiri choletsa, makamaka popeza chilinso ndi makhalidwe ena.

Zosavuta komanso zopepuka

Palibe mavavu pano, koma "kuwala" komwe kwamupatsa dzina loti "cylinder bore". Ndiko kupita kwa pisitoni kutsogolo kwa magetsi komwe kumatsimikizira kugawa, potero kupewa kugwiritsa ntchito camshafts imodzi kapena zingapo zoyendetsedwa ndi unyolo wokhala ndi ma tensioners, ma valve onse owongolera pogwiritsa ntchito otsetsereka kapena matepi. Zida zosinthira zomwe zimabweretsa kutsika mtengo kopanga komanso kukonza ndi kulemera. Makhalidwe omwe amamupangitsa kukhala ngwazi yampikisano.

Injini yamtsogolo!

Ndi jekeseni, yomwe imatumiza mafuta mu silinda pokhapokha mpweya wotulutsa mpweya utatsekedwa, mpweya wotulutsa mpweya umatetezedwa kuti usataye mpweya watsopano. Kuipitsa ndi kugwiritsira ntchito kumagawidwa ndi 2, kufika pamiyeso ya injini zamakono za 4-stroke ndikusunga ubwino wawo wachilengedwe. Ukadaulo uwu umagwiritsidwa ntchito ndi Rotax pa 600 ndi 800 Skidoo twin-cylinders (chithunzi), omwe amapanga 120 ndi 163 hp. pa 8000 rpm, motero. Chilichonse chomwe tinganene, gawo lachiwiri silinatchulepo mawu ake omaliza !!!

2 kugunda ndi 3 mayendedwe

Sitiroko iwiri ili ndi dzinali chifukwa imachita magawo anayi a kuzungulira kwake ... mu masitepe awiri. Amakwaniritsa izi pogwira ntchito nthawi imodzi pamwamba ndi pansi pa pistoni. Tiyeni tione mwatsatanetsatane mmene izi zimagwirira ntchito.

Chithunzi #1:

(Pamwamba pa pisitoni): Kukweza pisitoni kumakakamiza kusakaniza. Iyi ndiye gawo la psinjika.

(Pansi pa pisitoni): Nthawi yomweyo, kusuntha kwa pisitoni kumawonjezera kuchuluka kwa crankcase. Choncho, kuvutika maganizo kumayamwa kusakaniza kupyolera mu ma valve. Ili ndiye gawo lovomerezeka.

Chithunzi #2:

(Pamwamba pa pisitoni): Pistoni yangofika kumene pamwamba pa sitiroko. Ali mu High Still, kapena PMH. Kutentha kochokera ku spark plug kumapangitsa kuti kusakaniza kuyaka ndipo pisitoni imayamba kutsika. Iyi ndi gawo la kuyaka.

(Pansi pa pisitoni): Voliyumu ya crankcase ndiyokwera kwambiri ndipo kutha kwake kumatha. Monga lamulo, nthawi zonse zamakono zimakhala ndi cholowera chocheperako komanso ma valve, monga pano, kuteteza kutulutsa mpweya watsopano womwe wangotengedwa kumene.

Chithunzi #3:

(Pamwamba pa pisitoni): Kuyaka kumawonjezera kuthamanga ndi kutentha. Mipweya imakula ndikutsitsa pisitoni. Iyi ndi gawo loyendetsa galimoto, lomwe limatchedwanso kupumula. Mwamsanga pamene kuwala kwa mpweya kumatsegula (kumanzere), kupanikizika kumatsika, potero kukonzekera kulowa kwa mpweya watsopano woponderezedwa munyumba yapansi.

(Pansi pa pisitoni): Kuchuluka kwa crankcase kumachepa, zomwe zimapangitsa kuti ma valve atseke ndipo mpweya watsopano (wobiriwira) umakanizidwa kale. Kutsegula magetsi otumizira posachedwapa kudzachotsa mpweya watsopano mu silinda. Amadziwika kuti lonse lotseguka utsi kuwala amalola mpweya ena kuthawa injini popanda kuwotcha. Akatswiri amatcha izi "short circuit"
