Kodi njira yozizira yamagalimoto awiri ndi iti?

Makina awiri oziziritsa magalimoto

Pawiri kuzirala dongosolo. Mitundu ina ya injini zamafuta a turbocharged imagwiritsa ntchito njira yozizirira yapawiri. Dera limodzi limapereka kuziziritsa kwa injini. Mpweya wina wozizirira pochangitsa. Mabwalo ozizirira amakhala odziyimira pawokha. Koma ali ndi cholumikizira ndipo amagwiritsa ntchito thanki yokulirapo wamba. Kudziyimira pawokha kwa mabwalo kumakupatsani mwayi kuti musunge kutentha kosiyanasiyana kwa zoziziritsa kukhosi mu iliyonse yaiwo. Kusiyana kwa kutentha kumatha kufika 100 ° C. Sakanizani zoziziritsa kuzizira, musalole ma valve awiri a cheke ndi ma throttles. Dera loyamba ndi makina oziziritsira injini. Dongosolo lozizira lokhazikika limapangitsa injini kukhala yofunda. Mu osiyanasiyana 105 ° C Mosiyana muyezo. Pazigawo ziwiri zozizira zozizira, kutentha kwa mutu wa silinda kumayikidwa pamtunda wa 87 ° C. Ndipo muzitsulo zazitsulo - 105 ° C. Izi zimatheka pogwiritsa ntchito ma thermostats awiri.

Dongosolo lozizira kawiri

Imakhala yozizira kwambiri. Popeza dera lamphamvu lamiyala limafunika kusungidwa kutentha pang'ono, kozizira kwambiri kumazungulira. Pafupifupi 2/3 yathunthu. Zozizira zotsalira zimazungulira mozungulira mozungulira. Kuonetsetsa kuti yunifolomu izizirala pamutu wamphamvu, ozizira amafalikira mmenemo. Kulowera komwe kutulutsa zochulukitsa mpaka kuchuluka kambiri. Izi zimatchedwa kuzizira kozungulira. Makina awiri ozizira makina. Kutentha kwambiri kwamutu wamphamvu kumatsagana ndi kuthamanga kozizira kwambiri. Kupsyinjika kumeneku kumakakamizidwa kuthana ndi thermostat ikatsegula. Kuwongolera kapangidwe kazinthu zoziziritsa kukhosi. Chimodzi mwama thermostats chimapangidwa ndi magawo awiri oyang'anira.

Makina awiri ozizira ntchito

Chitofu cha imodzi yotentha chimakhala ndi magawo awiri olumikizana. Mbale yaying'ono komanso yayikulu. Mbale yaying'ono imatsegulidwa koyamba, yomwe imakweza mbale yayikuluyo. Dongosolo lozizira limayang'aniridwa ndi makina oyang'anira injini. Injini ikayamba, onse awiri amatseka. Amapereka makina otentha. Firiji imazungulira mozungulira kochepa mozungulira mutu wamphamvu. Kuchokera pampu kudzera pamutu wamphamvu, chosinthira chotenthetsera, mafuta ozizira kenako ndikulowetsa mu thanki. Kuzungulira uku kumachitika mpaka kutentha kozizira kukafika 87 ° C. Pa 87 ° C, thermostat imatsegula m'mbali mwa mutu wamphamvu. Wozizilitsa amayamba kuzungulira mozungulira kwambiri. Kuchokera pampu kudzera pamutu wamphamvu. Chotenthetsera, kutentha exchanger, mafuta ozizira, imodzi kutsegula, rediyeta ndiyeno kudzera thanki kuwonjezeka.

Kodi kutentha kumatseguka pati?

Kuzungulira uku kumachitika mpaka kuziziritsa mu cylinder block kufika 105 ° C. Pa 105 ° C, thermostat imatsegula cylinder block circuit. Madziwo amayamba kuyendayenda mmenemo. Pachifukwa ichi, kutentha kwa mutu wa silinda nthawi zonse kumasungidwa pa 87 ° C. Chigawo chachiwiri ndi njira yoziziritsira mpweya. Dongosolo la chipangizo choziziritsira mpweya. Makina oziziritsira mpweya amakhala ndi chozizira, radiator ndi pampu. zomwe zimalumikizidwa ndi mapaipi. Dongosolo loziziritsa lilinso ndi nyumba yopangira ma turbocharger. The refrigerant mu dera amazunguliridwa ndi osiyana mpope. Zomwe zimayendetsedwa, ngati n'koyenera, ndi chizindikiro chochokera ku unit control unit. Madzi omwe amadutsa mu ozizira amachotsa kutentha kuchokera mumpweya wothira. Ndiye utakhazikika mu radiator.

Mafunso ndi Mayankho:

Ndi chiyani chomwe chikuphatikizidwa mu makina ozizirira injini? Dongosololi lili ndi jekete yoziziritsa yamagalimoto, pampu ya hydraulic, thermostat, mapaipi olumikizira, radiator ndi fan. Magalimoto ena amagwiritsa ntchito zida zina zowonjezera.

Kodi njira yozizirira yozungulira iwiri imagwira ntchito bwanji? Injini ikakhala yotenthetsera, choziziritsa kukhosi chimazungulira mozungulira pang'ono. Injini yoyatsira mkati ikafika kutentha, chotenthetsera chimatseguka ndipo choziziritsa kukhosi chimazungulira pa radiator mozungulira mozungulira.

N'chifukwa chiyani mukufunikira makina ozizirira amitundu iwiri? Pambuyo pa nthawi yopuma, injini iyenera kufika kutentha kwachangu, makamaka nyengo yozizira. Kuzungulira kwakukulu kumapereka kuziziritsa kwa mota.
