Kukangana pansi (mosamala).
Kaya timakonda kapena ayi, kugwedezeka kwamphamvu kumatsagana ndi zinthu zonse zosuntha zamakina. Zinthu sizili zosiyana ndi injini, zomwe ndi kukhudzana kwa pistoni ndi mphete ndi mbali yamkati ya masilinda, i.e. ndi malo awo osalala. Ndi m'malo awa komwe kutayika kwakukulu kuchokera kumakangano oyipa kumachitika, kotero opanga ma drive amakono akuyesera kuwachepetsa momwe angathere pogwiritsa ntchito matekinoloje atsopano.
Osati kutentha kokha
Kuti mumvetse bwino zomwe zikuyenda mu injini, ndikwanira kulowa mfundo zomwe zimayendera mu injini ya spark, kufika 2.800 K (pafupifupi 2.527 ° C), ndi dizilo (2.300 K - pafupifupi 2.027 ° C). . Kutentha kwakukulu kumakhudza kuwonjezeka kwa kutentha kwa gulu lotchedwa cylinder-piston gulu, lopangidwa ndi pistoni, mphete za pistoni ndi masilinda. Zotsirizirazi zimapundukanso chifukwa cha kukangana. Choncho, m'pofunika kuchotsa bwino kutentha kwa dongosolo lozizira, komanso kuonetsetsa mphamvu zokwanira zomwe zimatchedwa filimu yamafuta pakati pa pistoni zomwe zimagwira ntchito muzitsulo.
Chofunikira kwambiri ndikumangirira.
Gawoli likuwonetsa bwino momwe ntchito ya gulu la pisitoni latchulidwa pamwambapa. Zokwanira kunena kuti mphete za pistoni ndi pisitoni zimayenda pamwamba pa silinda pa liwiro la 15 m / s! N'zosadabwitsa kuti chidwi chochuluka chimaperekedwa kuti atsimikizire kulimba kwa malo ogwirira ntchito a masilinda. N’chifukwa chiyani kuli kofunika kwambiri? Kutayikira kulikonse mu dongosolo lonse kumabweretsa mwachindunji kuchepa kwa mphamvu yamakina a injini. Kuwonjezeka kwa kusiyana pakati pa ma pistoni ndi ma cylinders kumakhudzanso kuwonongeka kwa mafuta odzola, kuphatikizapo nkhani yofunika kwambiri, i.e. pa gawo lolingana la filimu yamafuta. Kuti muchepetse mikangano yoyipa (pamodzi ndi kutenthedwa kwa zinthu zamtundu uliwonse), zinthu zowonjezera mphamvu zimagwiritsidwa ntchito. Imodzi mwa njira zatsopano zomwe zikugwiritsidwa ntchito panopa ndi kuchepetsa kulemera kwa pistoni pawokha, kugwira ntchito m'masilinda amagetsi amakono.
NanoSlide - zitsulo ndi aluminiyamu
Ndiyeno, kodi cholinga chimene tatchulachi chingakwaniritsidwe motani m’zochita zake? Mercedes amagwiritsa ntchito, mwachitsanzo, ukadaulo wa NanoSlide, womwe umagwiritsa ntchito pisitoni zachitsulo m'malo mwazomwe zimagwiritsidwa ntchito kwambiri zomwe zimatchedwa aluminium reinforced. Ma pistoni achitsulo, pokhala opepuka (ndi otsika kuposa 13 mm kuposa aluminiyamu), amalola, mwa zina, kuchepetsa kuchuluka kwa ma crankshaft counterweights ndikuthandizira kukulitsa kulimba kwa mayendedwe a crankshaft ndi piston yonyamula yokha. Njira imeneyi tsopano ikugwiritsidwa ntchito kwambiri mu injini zoyatsira spark ndi kuponderezana. Kodi maubwino otani aukadaulo wa NanoSlide? Tiyeni tiyambe kuyambira pachiyambi: yankho loperekedwa ndi Mercedes limaphatikizapo kuphatikiza ma pistoni achitsulo okhala ndi aluminiyamu nyumba (masilinda). Kumbukirani kuti panthawi yogwiritsira ntchito injini, kutentha kwa pistoni kumakwera kwambiri kuposa pamwamba pa silinda. Panthawi imodzimodziyo, kukula kwa mzere wazitsulo za aluminiyamu kumakhala pafupifupi kuwirikiza kawiri kwazitsulo zachitsulo (zambiri mwazitsulo zomwe zimagwiritsidwa ntchito panopa ndi ma silinda amapangidwa kuchokera kumapeto). Kugwiritsiridwa ntchito kwa chitsulo cholumikizira pisitoni-aluminiyamu yolumikizira nyumba kumatha kuchepetsa kwambiri kukwera kwa pisitoni mu silinda. Ukadaulo wa NanoSlide umaphatikizanso, monga momwe dzinalo likusonyezera, zomwe zimatchedwa sputtering. nanocrystalline ❖ kuyanika pa kubala pamwamba yamphamvu, amene kwambiri amachepetsa roughness pamwamba pake. Komabe, ponena za ma pistoni okha, amapangidwa ndi zitsulo zonyezimira komanso zamphamvu kwambiri. Chifukwa chakuti iwo ndi otsika kusiyana ndi anzawo a aluminiyamu, amadziwikanso ndi kulemera kochepa kwazitsulo. Ma pistoni achitsulo amapereka kulimba kwabwino kwa malo ogwirira ntchito a silinda, omwe amawonjezera mwachindunji mphamvu ya injini powonjezera kutentha kwa ntchito m'chipinda chake choyaka. Izi, zimatanthawuza ubwino wowotcha wokha komanso kuyaka bwino kwa mafuta osakaniza mpweya.
