Injiniyo imayendetsa jekeseni wamadzi

Mwina mudamvapo kale za dongosolo la (Panthawi yotsutsana) la Pantone, lomwe limagwiritsa ntchito madzi mu injini kuti achepetse kugwiritsidwa ntchito kwamafuta ndi kuipitsa chilengedwe. Ngati chotsatiracho chikungokhudza "odzipangira nokha", dziwani kuti makampani akuluakulu akuyamba kuphunzira nkhaniyi, ngakhale sitingathe kulankhula mozama za dongosolo la Pantone (zambiri apa).

Zowonadi, dongosololi ndilosavuta kumvetsetsa pano, ngakhale litakhala lofanana kwambiri.

Zindikirani kuti titha kupanganso kulumikizana ndi nitrous oxide (yomwe ena amatcha nitro), yomwe nthawi ino ndi kukakamiza injini ndi okosijeni, onani apa kuti mudziwe zambiri.

Kodi ntchito?

Ndikukutsimikizirani kuti njira yogwiritsira ntchito injini yopangira madzi ndiyosavuta kuphunzira.

Choyamba, muyenera kumvetsetsa mfundo zingapo, monga kuti injini imagwira ntchito bwino pamene mpweya wozizira umaperekedwa kwa iyo. Inde, mpweya wozizira umatenga malo ochepa kuposa mpweya wotentha, kotero titha kuyika zochuluka muzipinda zoyaka kukazizira (zowonjezera zowonjezera = kuyaka kwambiri). Ndizofanana kwambiri mukawombera moto kuti mutengerepo mwayi).

Mumvetsetsa, cholinga apa ndikuziziritsa mpweya wolowa mu injini kwambiri.

Inde, mu buluu kudya zobwezedwa

Zoona zake n’zakuti nthawi zambiri mpweya umalowa mu injiniyo ndi kutentha kwambiri, ndiye n’chifukwa chiyani muyike kachipangizo kamene kamaziziritsa kwambiri? Chabwino, ziyenera kukumbukiridwa kuti injini zambiri zamakono zimagwiritsa ntchito turbocharging ... Ndipo aliyense amene anganene turbo, akunena kuti mpweya wopanikizika umalowa mkati (turbo imagwira ntchito pano). Ndipo akatswiri a sayansi ya zakuthambo adzazindikira mwamsanga kuti mpweya woponderezedwa = kutentha (imeneyi ndi mfundo yopondereza / yowonjezera yomwe imagwiritsidwa ntchito kuwongolera mpweya).

Mwachidule, mpweya uliwonse wopanikizika umayamba kutentha. Choncho, pa nkhani ya injini ya Turbo, yotsirizirayo imakhala yotentha kwambiri mukakhala pa rpm (kuthamanga kwa turbocharger kumawonjezeka). Ndipo ngakhale muli ndi cholumikizira / chotenthetsera kutentha kuti muziziritsa mpweya wochokera ku turbo, mpweya ukadali wotentha kwambiri!

Nawa amodzi mwa ma valve olowetsa omwe amatsegula kuti mpweya ulowe.

Choncho, cholinga chidzakhala ku kuziziritsa mpweya en jekeseni wa madzi mu mawonekedwe a ma microdroplets polowera (monga mpweya usanalowe mu masilinda). Njirayi ikufanananso ndi jekeseni wosadziwika, womwe umaphatikizapo jekeseni wa petulo pa mlingo wokwanira osati mu injini.

Chifukwa chake mvetsetsani kuti jakisoni wamadzi uyu siwokhazikika, ndiwopindulitsa pomwe mpweya wolowa m'malowo uli wotentha mokwanira.

Chifukwa chake, makinawa ndioyenera kutengera injini zamafuta ndi dizilo zomwe zili ndi vuto lomwelo.

BMW paulendo

Mfundo imeneyi inagwiritsidwa ntchito mu M4 ndi 1i prototypes 118-yamphamvu Series 3.

Malingana ndi chizindikirocho ndipo pambuyo pa mayesero ambiri, padzakhala kuwonjezeka 10% mphamvu za 8% kumwa ndi kochepa! Tonse chifukwa chakuzizira mpaka 25%.

Komabe, ziyenera kudziwidwa kuti zosungirako

m'pofunika kwambiri kugwiritsa ntchito injini

Chifukwa chake, zimathandiza kuchepetsa kuwononga mafuta mopitilira muyeso komwe kumachitika chifukwa choyendetsa mwamphamvu (injini za dizilo sizigwiritsa ntchito mafuta pang'ono molunjika). Choncho amene amayendetsa masewera adzapindula kwambiri ndi ndalama. BMW points 8% poyendetsa

"Wamba"

et pafupifupi 30% poyendetsa

kusewera

(Monga ndafotokozera kale, dongosololi limagwiritsidwa ntchito makamaka pamene mpweya wolowa umakhala wotentha, ndipo ndi pamene mukukwera nsanja).

Zopindulitsa zina?

Dongosololi lipereka maubwino ena:

• Chiŵerengero cha compression chikhoza kuwonjezeka, chomwe chimawonjezera ntchito.
• Poyatsira (petulo) amatha kuyatsa kale, zomwe zimapangitsa kuti mafuta azigwiritsidwa ntchito.
• Dongosololi lidzalola kugwiritsa ntchito mafuta otsika, omwe angakhale opindulitsa m'maiko ena.

Komano, ndikuwona chimodzi chokha: dongosolo limawonjezera chiwerengero cha zigawo zomwe zimapanga injini. Chifukwa chake, kudalirika kumakhala kocheperako bwino (chovuta kwambiri chinthucho, ndiye kuti kuthekera kwake kulephera).

Ngati muli ndi malingaliro ena kuti mumalize nkhaniyi, khalani omasuka kutero pansi pa tsamba!
