Kodi pali kusiyana kotani pakati pa 4 sitiroko ndi 2 sitiroko injini?
Ma injini a sitiroko anayi ndi awiri ali ndi zigawo zofanana koma amagwira ntchito mosiyana. Ma injini anayi a sitiroko nthawi zambiri amapezeka pa ma SUV.
Kodi stroke ya injini ndi chiyani?
Magalimoto ambiri atsopano, magalimoto ndi ma SUV ali ndi injini zomwe zimakhala zotsika mtengo kwambiri. Kuti injini iliyonse igwire ntchito bwino, iyenera kutsiriza kuyaka, komwe kumaphatikizapo mikwingwirima inayi ya ndodo yolumikizira ndi pistoni mkati mwa chipinda choyatsira mu injini ya sitiroko zinayi, kapena ziwiri mu injini ya sitiroko ziwiri. Kusiyana kwakukulu pakati pa injini ya sitiroko ziwiri ndi injini ya sitiroko zinayi ndikuyatsa nthawi. Nthawi zambiri amawombera amakuuzani momwe amasinthira mphamvu ndi momwe zimakhalira mwamsanga.
Kuti mumvetse kusiyana pakati pa injini ziwirizi, muyenera kudziwa kuti sitiroko ndi chiyani. Njira zinayi zimafunikira kuwotcha mafuta, iliyonse yomwe imaphatikizapo kuzungulira kumodzi. M'munsimu muli zikwapu zinayi zomwe zimakhudzidwa ndi ndondomeko ya sitiroko zinayi.
Sitiroko yoyamba ndi kumwa Sitiroko. Injini imayamba pakugunda pistoni ikagwetsedwa pansi. Izi zimathandiza kuti kusakaniza kwa mafuta ndi mpweya kulowa m'chipinda choyaka moto kudzera mu valve yolowera. Panthawi yoyambira, mphamvu yomaliza kugunda imaperekedwa ndi injini yoyambira, yomwe ndi injini yamagetsi yolumikizidwa ku flywheel yomwe imatembenuza crankshaft ndikuyendetsa silinda iliyonse.
Sitiroko yachiwiri (mphamvu). Ndipo amati chimene chagwa chiyenera kuwuka. Izi ndi zomwe zimachitika panthawi yoponderezedwa pamene pisitoni imasunthira kumbuyo kwa silinda. Pa sitiroko iyi, valavu yolowetsa imatsekedwa, yomwe imakanikiza mafuta osungidwa ndi mpweya wa mpweya pamene pisitoni ikupita pamwamba pa chipinda choyaka moto.
Kukwapula kwachitatu - kuyaka. Apa ndi pamene mphamvu zimapangidwira. Pistoni ikangofika pamwamba pa silinda, mipweya yopanikizidwayo imayatsidwa ndi spark plug. Izi zimapanga kaphulika kakang'ono mkati mwa chipinda choyaka chomwe chimakankhira pisitoni pansi.
Sitiroko yachinayi - utsi. Izi zimatsirizitsa njira yoyatsira inayi pamene pisitoni imakankhidwira mmwamba ndi ndodo yolumikizira ndipo valavu yotulutsa mpweya imatsegula ndikutulutsa mpweya wopsereza woyaka kuchokera kuchipinda choyaka.
Sitiroko imawerengedwa ngati kusintha kumodzi, kotero mukamva mawu akuti RPM amatanthauza kuti ndi kuzungulira kwathunthu kwa mota kapena mikwingwirima inayi pakusintha. Choncho, injini ikakhala ikuchita 1,000 rpm, izi zikutanthauza kuti injini yanu ikumaliza ntchito ya sitiroko inayi ka 1,000 pa mphindi imodzi, kapena pafupifupi 16 pa sekondi iliyonse.
Kusiyana pakati pa injini za sitiroko ziwiri ndi zinayi
Kusiyanitsa koyamba ndikuti ma spark plugs amayaka kamodzi pakusintha kwa injini yamitundu iwiri ndikuyatsa kamodzi pa sekondi imodzi mu injini ya sitiroko zinayi. Revolution ndi imodzi mwa masinthidwe anayi. Ma injini a sitiroko anayi amalola sitiroko iliyonse kuti ichitike palokha. Injini yokhala ndi mikwingwirima iwiri imafuna njira zinayi kuti zichitike mmwamba ndi pansi, zomwe zimapatsa dzina lake.
Kusiyana kwina ndikuti ma injini a sitiroko awiri safuna mavavu chifukwa kulowetsa ndi utsi ndi gawo la kukanikiza kwa pisitoni ndi kuyaka. M'malo mwake, pali doko lotulutsa mpweya m'chipinda choyaka moto.
Ma injini awiri a sitiroko alibe chipinda chosiyana cha mafuta, choncho ayenera kusakanizidwa ndi mafuta mu milingo yoyenera. Chiŵerengero chapadera chimadalira galimotoyo ndipo chikuwonetsedwa mu bukhu la eni ake. Miyezo iwiri yodziwika bwino ndi 50: 1 ndi 32: 1, pomwe 50 ndi 32 imanena za kuchuluka kwa mafuta pagawo lililonse lamafuta. Injini yokhala ndi mikwingwirima inayi ili ndi chipinda chosiyana chamafuta ndipo sichifuna kusakaniza. Ichi ndi chimodzi mwa njira zosavuta kudziwa kusiyana pakati pa mitundu iwiri ya injini.
Njira ina yodziwira awiriwa ndi mawu. Ma injini a sitiroko aŵiri nthawi zambiri amalira mokweza kwambiri, pamene injini ya sitiroko inayi imapangitsa kung’ung’udza kofewa. Ma injini a sitiroko awiri nthawi zambiri amagwiritsidwa ntchito m'makina otchetcha udzu ndi magalimoto okwera kwambiri (monga njinga zamoto ndi matalala a chipale chofewa), pomwe injini zokhala ndi sitiroko zinayi zimagwiritsidwa ntchito pamagalimoto apamsewu komanso ma injini othamanga kwambiri.
