Galimoto yozizira dongosolo. Yang'anani musananyamuke
Mwinamwake aliyense anawona galimotoyo itaima pambali pa msewu ndi chivundikiro chotseguka ndi kukwera kwa mitambo ya nthunzi. Kodi mungapewe bwanji kuti izi zisakuchitikireni? Tikulemba izi pansipa ...
Musanayambe kufotokoza za kuwonongeka kwa dongosolo yozizira, ndi bwino kulabadira lingaliro la kugwiritsa ntchito dongosolo lino mu injini kuyaka mkati.
Eya, injini imagwira ntchito bwino mumikhalidwe yotsimikizika ya thermodynamic (kutentha kozizira ndi pafupifupi 90-110 digiri Celsius).
Izi sizikugwiranso ntchito pamtundu wa dizilo, womwe uyenera kuyatsidwa pamatenthedwe otsika ndi mapulagi owala powonjezera kutentha kwa chipinda choyaka moto, komanso mtundu wamafuta. Injini yoyatsira mkati - zonse dizilo ndi mafuta - imawotcha osakaniza opangidwa bwino ndi mpweya pokhapokha pa kutentha kwina. Ngati kutentha komwe kuyaka kumakhala kochepa kwambiri, ndiye kuti mafuta ochulukirapo amaperekedwa (motero kuyaka kwakukulu pa "injini ya undercooled"), mafuta samawotcha kwathunthu, zinthu zovulaza zimatulutsidwa, ndipo tinthu tating'ono tamafuta osawotchedwa timayenda pansi pa injiniyo. yamphamvu pamwamba ndi kusakaniza mafuta kuchepetsa mafuta ake katundu.
Onaninso: layisensi yoyendetsa. Khodi 96 yagulu B yokoka ngolo
Ngati kutentha kuli kwakukulu kwambiri, kuyaka mwadzidzidzi kumachitika, i.e. kuyatsa kosalamulirika kumayamba, ndipo vuto ndi kuchepetsedwa - ndi kutentha kwakukulu - kwa mafuta, ndipo, chifukwa chake, kuwonongeka kwa mafuta. Zikavuta kwambiri, kutentha kwambiri kwa pistoni/silinda kungayambitse kutentha kwakukulu kwa pistoni, zomwe nthawi zambiri zimabweretsa kugwidwa.
Izi ndizotipangitsa kuti tizisamalira bwino njira yozizirira bwino, makamaka tikagula galimoto yogwiritsidwa ntchito ndipo sitinakhalepo ndi mwayi wophunzira za momwe zimakhudzira panthawi yolemetsa yolemetsa m'chilimwe (mwachitsanzo, kuyendetsa galimoto yodzaza. galimoto kumapiri).
Onaninso: Momwe mungasamalire batri?
Kotero, ndi zigawo ziti zomwe zimazizira zimakhala ndi zomwe muyenera kuziganizira?
Nthawi zambiri, kuzirala ndi: makina olowera mpweya wa injini, pampu yozizirira, v-belt/v-belt, thermostat, radiator ndi fan. Chozizira, chomwe chimatuluka ndi mpope wamadzimadzi woyendetsedwa ndi crankshaft, mutatuluka muzitsulo za injini, umalowa m'chipinda cha thermostatic valve ndikubwerera ku injini (pamene thermostat yatsekedwa, tili ndi dera lotchedwa laling'ono. zomwe zimalola injini kutentha mofulumira) kapena kumapitirizabe kuzizira, kumene madziwo amakhala atakhazikika (chomwe chimatchedwa kufalikira kwakukulu).
Chofala komanso chosavuta kukonza vuto la kutentha kwa injini ndi thermostat. Ikalephera, kutuluka kwaufulu kumalo otentha kumatsekedwa ndipo kutentha kwa kutentha sikugwiritsidwa ntchito mokwanira. Komabe, nthawi zambiri zimachitika kuti injini yokhala ndi thermostat yothandiza imatenthedwabe. Pankhaniyi, pampu / lamba pagalimoto nthawi zambiri ndi chifukwa cha kulephera.
