GY6 4t injini - zonse muyenera kudziwa za Honda powertrain

Mabaibulo awiri angapezeke pamsika: 50 ndi 150 cc injini. Poyamba, injini ya GY6 imatchedwa QMB 139, ndipo yachiwiri, QMJ157. Dziwani zambiri za gawo lagalimoto m'nkhani yathu!

Zambiri za njinga yamoto Honda 4T GY6

Pambuyo kuwonekera koyamba kugulu mu 60s, Honda sanathe kugwiritsa ntchito njira zatsopano mapangidwe kwa nthawi yaitali. M'zaka za m'ma 80, chiwembu chatsopano chinapangidwa, chomwe chinakhala chopambana. Chinali chipinda chimodzi chokhala ndi sitiroko zinayi chokhala ndi mpweya kapena mafuta. Ilinso ndi ma valve awiri apamwamba.

Iwo anali lolunjika yopingasa ndipo anaikidwa pa njinga yamoto ambiri ang'onoang'ono ndi scooters - njira za tsiku ndi tsiku zoyendera anthu aku Asia, monga Taiwan, China kapena maiko a kum'mwera chakum'mawa kwa kontinenti. Ntchitoyi anakumana ndi chidwi moti posakhalitsa makampani ena anayamba kupanga mayunitsi kapangidwe ofanana, mwachitsanzo, Kymco Pulsar CB125, amene anali kusinthidwa Honda KCW 125.

Injini ya GY6 mumitundu ya QMB 139 ndi QMJ 158 - data yaukadaulo

Chigawo chaching'ono cha sitiroko zinayi chimagwiritsa ntchito choyambira chamagetsi chokhala ndi kickstand. Chipinda choyaka moto cha hemispherical chinayikidwa ndipo mawonekedwe a silinda adapangidwa mumtundu wa SOHC wokhala ndi camshaft mumutu wa silinda. Anabala 39 mm, sitiroko 41.4 mm. Voliyumu yonse yogwira ntchito inali ma kiyubiki mita 49.5. masentimita pa compression chiŵerengero cha 10.5:1.. Anapereka mphamvu ya 2.2 hp. pa 8000 rpm. ndipo mphamvu ya thanki yamafuta inali malita 8.

Mtundu wa QMJ 158 ulinso ndi choyambira chamagetsi chokhala ndi choyimira. Ndiwoziziritsidwa ndi mpweya ndipo imakhala ndi malo okwana 149.9cc. Mphamvu yayikulu kwambiri ndi 7.5 hp. pa 7500 rpm. ndi silinda anabowola 57,4 mm, pisitoni sitiroko 57,8 mm ndi psinjika chiŵerengero cha 8:8:1.

Kukonzekera kwa galimoto - chidziwitso chofunikira kwambiri

GY6 imagwiritsa ntchito kuzirala kwa mpweya komanso camshaft yoyendetsedwa ndi camshaft. Mapangidwewo adaphatikizanso mutu wa silinda wa semi-cylindrical cross-flow cylinder. Kuyeza kwamafuta kunachitidwa ndi carburetor imodzi ya mbali imodzi pa liwiro lokhazikika. Chigawochi chinali kutsanzira kapena 1:1 kutembenuka kwa gawo la Keihin CVK.

Choyatsira cha CDi capacitor chokhala ndi maginito oyendetsa ndege chinagwiritsidwanso ntchito. Chifukwa chakuti chinthu ichi chili pa flywheel, osati pa camshaft, kuyatsa kumachitika panthawi yoponderezedwa ndi kutulutsa mpweya - uwu ndi mtundu wamoto wamoto.

Mphamvu ndi kufala kosalekeza kosinthika

Galimoto ya GY6 ili ndi maginito omangidwa omwe amapereka 50VAC ku CDi system komanso 20-30VAC yokonzedwa ndikuwongolera ku 12VDC. Chifukwa cha iye, mphamvu inaperekedwa kwa zipangizo zomwe zili mu chassis, monga kuyatsa, komanso kulipiritsa batire.

Kutumiza kwa CVT komwe kumayendetsedwa ndi centrifugally kumakhala mu swingarm yophatikizika. Imagwiritsa ntchito mphira ndipo nthawi zina imatchedwanso VDP. Kumbuyo kwa swingarm, clutch ya centrifugal imalumikiza kufalikira kwa zida zosavuta zochepetsera. Zoyamba mwazinthuzi zimakhalanso ndi choyambira chamagetsi, zida zoboola kumbuyo ndi choyambira.

Ndikoyeneranso kutchula kuti palibe zowawa pakati pa crankshaft ndi zosinthika - zimayendetsedwa ndi clutch yamtundu wa centrifugal yomwe ili kumbuyo kwa pulley. Njira zofananira zagwiritsidwa ntchito, mwachitsanzo. mu zinthu monga Vespa Grande, Bravo ndi kusinthidwa Honda Camino/Hobbit. 

GY6 injini ikukonzekera - malingaliro

Monga momwe zimakhalira ndi injini zambiri zoyatsira mkati, mtundu wa GY6 ukhoza kupangidwa ndi masinthidwe ambiri kuti apititse patsogolo magwiridwe antchito ake. Chifukwa cha izi, njinga yamoto yovundikira kapena kart momwe galimotoyo imayikidwa idzakhala yachangu komanso yamphamvu. Komabe, ziyenera kukumbukiridwa kuti izi zimafuna chidziwitso chapadera ndi chidziwitso kuti zisawononge chitetezo.

Kuchuluka kwa mpweya

Chimodzi mwazosintha zomwe zimachitika pafupipafupi ndikuwonjezera kutuluka kwa mpweya wotulutsa mpweya. Izi zitha kuchitika posintha masheya, ma mufflers wamba ndi mtundu wosinthidwa - izi zitha kupezeka m'masitolo apaintaneti. 

Izi zidzakulitsa ntchito ya injini - mwatsoka, zigawo zomwe zimayikidwa pamafakitale opanga zimachepetsa mphamvu ya injini kuti ichotse mpweya wotulutsa mpweya pamagetsi otsika. Chifukwa cha izi, kufalikira kwa mpweya mu gawo lamagetsi kumakhala koipitsitsa.

Mutu mphero

Njira zina zowonjezera ntchito ya mphamvu yamagetsi zimaphatikizapo kuonjezera chiwerengero cha kuponderezana, chomwe chidzakhudza bwino torque ndi mphamvu yopangidwa ndi mphamvu yamagetsi. Izi zikhoza kuchitika mwa mphero kumutu ndi katswiri.

Zimagwira ntchito m'njira yoti gawo lopangidwa ndi makina lichepetse kuchuluka kwa chipinda choyaka moto ndikuwonjezera kuchuluka kwa kuponderezana. Samalani kuti musapitirire, chifukwa izi zingayambitse kuponderezana kwambiri, zomwe zingayambitse kugwirizana pakati pa pistoni ndi ma valve a injini.

GY6 ndi chida chodziwika chomwe chimapereka mwayi wambiri.

 Idzagwira ntchito yokhazikika komanso ngati injini yosinthira. Pachifukwa ichi, injini ya GY6 ndiyotchuka kwambiri. Zimakwanira ma scooters ndi karts. Galimoto ndi mtengo wokongola ndi kuthekera kwa kupanga zosintha ndi kupezeka mkulu wa otchedwa. zida zosinthira kuti muwonjezere magwiridwe antchito a unit.
