Jekeseni wamadzi mu injini yamagalimoto

Mphamvu zamagalimoto ndimutu wodziwika kwambiri m'magulu oyendetsa magalimoto. Pafupifupi aliyense woyendetsa amaganiza kamodzi za momwe angakulitsire magwiridwe antchito a magetsi. Ena amaika makina amagetsi, ena masilindala, ndi zina. (njira zina zowonjezera mphamvu zafotokozedwa mu stаwakuba). Ambiri omwe ali ndi chidwi ndi kukonza magalimoto amadziwa makina omwe amapereka madzi pang'ono kapena kusakaniza ndi methanol.

Oyendetsa magalimoto ambiri amadziwa lingaliro ngati nyundo yamadzi yamagalimoto (palinso osiyana review). Kodi madzi, omwe angayambitse kuwonongeka kwa injini yoyaka mkati, nthawi yomweyo kuwonjezera magwiridwe ake? Tiyeni tiyesetse kuthana ndi nkhaniyi, ndikuganiziranso zabwino ndi zoyipa zomwe jekeseni wa methanol yamadzi ili nayo pagawo lamagetsi.

Kodi jakisoni wamadzi ndi chiyani?

Mwachidule, dongosololi ndi thanki momwe amathiramo madzi, koma nthawi zambiri amakhala osakaniza a methanol ndi madzi mu 50/50 ratio. Ili ndi mota wamagetsi, mwachitsanzo, yochotsa pazenera lakutsogolo. Dongosololi limalumikizidwa ndi machubu otanuka (mu bajeti yambiri, ma hoses ochokera ku dropper amatengedwa), kumapeto kwake komwe kumayikidwa mphuno yapadera. Kutengera mtundu wamachitidwe, jakisoniyo imachitika kudzera mu atomizer imodzi kapena zingapo. Madzi amaperekedwa pamene mpweya utulutsidwa.

Ngati titenga mtundu wa fakitore, ndiye kuti chipangizocho chimakhala ndi mpope wapadera womwe umayendetsedwa pakompyuta. Makinawa adzakhala ndi sensa imodzi kapena zingapo zothandizira kudziwa nthawi ndi kuchuluka kwa madzi opopera.

Kumbali imodzi, zikuwoneka kuti madzi ndi mota ndizosagwirizana. Kuyaka kwa mafuta osakanikirana ndi mpweya kumachitika mu silinda, ndipo, monga aliyense amadziwa kuyambira ubwana, lawi (ngati si mankhwala omwe amawotcha) limazimitsidwa ndi madzi. Anthu omwe "adadziwana" ndi hayidiroliki yamagalimoto, kuchokera pa zomwe adaziwona, adatsimikiza kuti madzi ndiye chinthu chomaliza chomwe chiyenera kulowa mu injini.

Komabe, lingaliro la jekeseni wamadzi si lingaliro launyamata. M'malo mwake, lingaliro ili lili pafupi zaka zana. M'zaka za m'ma 1930, pazosowa zankhondo, Harry Ricardo adakonza injini za ndege za Rolls-Royce Merlin, komanso adapanga mafuta opangira okhala ndi nambala yayikulu ya octane. apa) zama injini amkati oyaka ndege. Kuperewera kwa mafuta koteroko ndikowopsa kwa kuphulika mu injini. Nchifukwa chiyani njirayi ndi yoopsa? payokha, koma mwachidule, chisakanizo cha mafuta-mpweya chikuyenera kuwotcha wogawana, ndipo pamenepa chimaphulika kwenikweni. Chifukwa chaichi, magawo a chipanichi amakhala ndi nkhawa zambiri ndipo amalephera mwachangu.

Pofuna kuthana ndi izi, G. Ricardo adachita maphunziro angapo, chifukwa chake adakwanitsa kupondereza kuphulika chifukwa chobayira madzi. Kutengera ndi zomwe adachita, mainjiniya aku Germany adakwanitsa kuwirikiza kawiri mphamvu yama unit mu ndege zawo. Pachifukwa ichi, mawonekedwe a MW50 (methanol wasser) adagwiritsidwa ntchito. Mwachitsanzo, womenya Focke-Wulf 190D-9 anali ndi injini yemweyo. Kutulutsa kwake kwakukulu kunali mphamvu ya mahatchi 1776, koma ndi kuwotcha kwakanthawi kochepa (kusakaniza kotchulidwa pamwambapa kunadyetsedwa muzipilala), bala iyi idakwera mpaka 2240 "mahatchi".

Izi sizinangogwiritsidwa ntchito munjira iyi ya ndege. The nkhokwe ya ndege German ndi American, panali zosintha angapo mayunitsi mphamvu.

Ngati tikulankhula zamagalimoto opanga, ndiye kuti mtundu wa Oldsmobile F85 Jetfire, womwe unayambira pamzera wa 62th wazaka zapitazi, udalandira fakitala wamadzi. Galimoto ina yopanga yomwe imathandizira injini motere ndi Saab 99 Turbo, yomwe idatulutsidwa mu 1967.

Ndege za Oldsmobile F85

Apeza 99 Turbo

Kutchuka kwa dongosololi kudakula chifukwa chakuwugwiritsa ntchito mu 1980-90. m'galimoto zamasewera. Chifukwa chake, mu 1983, Renault imakonzekeretsa magalimoto ake a Fomula 1 ndi thanki ya malita 12, momwe amapopera magetsi, chowongolera pamagetsi ndi kuchuluka kwa jakisoni. Pofika 1986, akatswiri a gululi adakwanitsa kuwonjezera makokedwe ndi mphamvu yamagetsi kuchokera pa 600 mpaka 870 ndiyamphamvu.

Pankhondo yothamanga ya opanga makina, Ferrari nayenso sanafune "kudyetsa kumbuyo", ndipo adaganiza zogwiritsa ntchito njirayi mgalimoto zake zamasewera. Chifukwa cha kusinthaku, chizindikirocho chidakwanitsa kutsogolera pakati pa opanga. Lingaliro lomwelo lidapangidwa ndi mtundu wa Porsche.

Kukonzanso kofananako kunachitika ndi magalimoto omwe amatenga nawo mbali m'mipikisano yochokera mndandanda wa WRC. Komabe, koyambirira kwa zaka za m'ma 90, omwe adakonzekera mpikisano wotere (kuphatikiza F-1) adasintha malamulowo ndikuletsa kugwiritsa ntchito njirayi mgalimoto zothamanga.

Kupambana kwina mdziko la motorsport kunapangidwa ndi chitukuko chofananira pamipikisano yothamanga mu 2004. Mbiri ya ma mile imodzi idasweka ndimagalimoto awiri osiyana, ngakhale adayesayesa kufika pachimake ndi mitundu ingapo yama powertrain. Magalimoto awa a dizilo anali ndi zida zochulukitsira madzi.

Popita nthawi, magalimoto adayamba kulandira ma intercoolers omwe amachepetsa kutentha kwa mpweya usanalowe muzambiri. Chifukwa cha ichi, akatswiri adatha kuchepetsa ngozi yakugogoda, ndipo jekeseni silinali lofunikira. Kuwonjezeka kwamphamvu kwamphamvu kunatheka chifukwa chokhazikitsa dongosolo la nitrous oxide supply (lomwe lidawonekera mu 2011).

Mu 2015, nkhani idayambanso kuwonekera za jekeseni wamadzi. Mwachitsanzo, galimoto yatsopano yotetezera MotoGP yopangidwa ndi BMW ili ndi chida chopopera madzi. Pakuwonetsera kovomerezeka kwamagalimoto ochepa, woimira automaker waku Bavaria adati mtsogolomo akukonzekera kutulutsa mzere wazikhalidwe zosagwirizana ndi zomwezi.

Kodi madzi kapena jakisoni wa methanol amapatsa chiyani injini?

Chifukwa chake tiyeni tichoke m'mbiri kuti tichite. Chifukwa chiyani mota imafunikira jekeseni wamadzi? Madzi ochepa akamalowetsedwa (madontho osaposa 0.1 mm amapopera), akakumana ndi sing'anga wotentha, amasandulika kukhala gaseous wokhala ndi mpweya wokwanira.

BTC utakhazikika imapanikiza mosavuta, zomwe zikutanthauza kuti crankshaft iyenera kugwiritsa ntchito mphamvu zochepa kuti igwire. Chifukwa chake, kuyika kumalola mavuto angapo kuthetsedwa nthawi imodzi.

Choyamba, mpweya wotentha umakhala ndi kachulukidwe kochepa (pofuna kuyesa, mutha kutenga botolo la pulasitiki lopanda kanthu m'nyumba yotentha ndikulizizira - lichepa bwino), kuti mpweya wocheperako usalowe muntanda, zomwe zikutanthauza kuti mafuta kapena dizilo mafuta amayaka kwambiri. Pofuna kuthetsa izi, injini zambiri zili ndi turbochargers. Koma ngakhale pankhaniyi, kutentha kwa mpweya sikumatsika, chifukwa makina amagetsi akale amapangidwa ndi utsi wotentha womwe umadutsa munthawi zambiri za utsi. Kupopera madzi kumapangitsa kuti mpweya wambiri uperekedwe kuzitsulo kuti zipititse patsogolo kuyaka. Chifukwa chake, izi zikhala ndi zotsatirapo zabwino pa chothandizira (mwatsatanetsatane, werengani mu ndemanga yapadera).

Kachiwiri, jekeseni wamadzi imathandizira kuwonjezera mphamvu yamagetsi popanda kusintha magwiridwe antchito komanso osasintha kapangidwe kake. Chifukwa chake ndichakuti, pakakhala nthunzi, chinyezi chimatenga voliyumu yambiri (malinga ndi kuwerengera kwina, voliyumu imakulitsa nthawi 1700). Madzi akasanduka nthunzi m'malo ochepa, kupanikizika kwina kumapangidwa. Monga mukudziwa, kupanikizika ndikofunikira kwambiri pamakokedwe. Popanda kuchitapo kanthu pakupanga kwamagetsi ndi chopangira mphamvu, gawo ili silingakwere. Ndipo popeza nthunzi imakula kwambiri, mphamvu zambiri zimatulutsidwa pakuyaka kwa HTS.

Chachitatu, chifukwa cha kupopera madzi, mafuta samapitilira kutentha, ndipo kuphulika sikupanga mu injini. Izi zimalola kugwiritsa ntchito mafuta otsika mtengo okhala ndi nambala yocheperako ya octane.

Chachinayi, chifukwa cha zomwe zatchulidwa pamwambapa, dalaivala sangakakamize poyatsira gasi mwachangu kuti galimoto ikhale yamphamvu kwambiri. Izi zimatsimikiziridwa ndikupopera madzi mu injini yoyaka yamkati. Ngakhale mphamvu ikuchulukirachulukira, kugwiritsiridwa ntchito kwamafuta sikuwonjezeka. Nthawi zina, ndimayendedwe ofanana oyendetsa, kususuka kwa magalimoto kumatsika mpaka 20 peresenti.

M'malo mwake, kukula uku kuli ndi otsutsa. Malingaliro olakwika kwambiri okhudza jekeseni wamadzi ndi awa:

1. Nanga bwanji nyundo yamadzi? Sitingakane kuti madzi akalowa m'miyalayimale, mota imakumana ndi nyundo yamadzi. Popeza madzi amakhala ndi kachulukidwe kabwino pisitoni ikagundika, siyingathe kufika pakatikati pakufa (izi zimadalira kuchuluka kwa madzi), koma crankshaft imapitilizabe kuzungulira. Izi zimatha kupindika ndodo zolumikizira, kuthyola makiyi, ndi zina zambiri. M'malo mwake, jakisoni wamadzi ndi wocheperako kotero kuti kuponderezana sikumakhudzidwa.
2. Metal, yolumikizana ndi madzi, imathamanga pakapita nthawi. Izi sizingachitike ndi dongosololi, chifukwa kutentha kwamakina oyendetsa injini kumadutsa madigiri 1000. Madzi amasintha kukhala nthunzi pamadigiri 100. Chifukwa chake, pantchitoyo, palibe injini mu injini, koma nthunzi yotentha kwambiri. Mwa njira, mafuta akawotcha, pamakhalanso mpweya wambiri mumafuta otulutsa utsi. Umboni wochepa wa izi ndi madzi omwe amatuluka mu chitoliro chotulutsa utsi (zifukwa zina zowonekera zikufotokozedwa apa).
3. Madzi akawoneka mumafuta, mafutawo amatuluka. Apanso, kuchuluka kwa madzi opopera ndi ochepa kwambiri kotero kuti sangathe kulowa mu crankcase. Nthawi yomweyo imakhala mpweya womwe umachotsedwa limodzi ndi utsi.
4. Mpweya wotentha umawononga kanema wamafuta, ndikupangitsa kuti magetsi agwire mphero. M'malo mwake, nthunzi kapena madzi sizimasungunula mafutawo. Zosungunulira zenizeni zenizeni ndi mafuta chabe, koma nthawi yomweyo kanema wamafuta amakhalabe makilomita mazana masauzande.

Tiyeni tiwone momwe chida chopopera madzi mgalimoto chimagwirira ntchito.

Momwe makina obayira madzi amagwirira ntchito

M'magulu amakono amakono omwe ali ndi dongosolo lino, zida zosiyanasiyana zitha kukhazikitsidwa. Nthawi ina, nozzle imodzi imagwiritsidwa ntchito, yomwe ili pamalo olowera asanabweretse bifurcation. Kusintha kwina kumagwiritsa ntchito ma jakisoni angapo amtunduwo anagawira jekeseni.

Njira yosavuta yokwera makina oterewa ndikukhazikitsa thanki ina yamadzi momwe mpope wamagetsi adzaikidwire. Chubu cholumikizidwa ndi icho, kudzera momwe madzi amaperekera kwa opopera. Injini ikafika pofika kutentha (kutentha kwa injini yoyaka mkati kumafotokozedwa m'nkhani ina), dalaivala akuyamba kupopera mbewu kuti apange utsi wonyowa munthawi zambiri.

Kukhazikitsa kosavuta kumatha kukhazikitsidwa pa injini ya carburetor. Koma nthawi yomweyo, munthu sangachite popanda kusintha kwamachitidwe. Poterepa, dongosololi limayang'aniridwa kuchokera pagalimoto yonyamula ndi driver.

M'masinthidwe apamwamba kwambiri, omwe amapezeka m'masitolo ogwiritsira ntchito magalimoto, mawonekedwe a kutsitsi amaperekedwa mwina ndi microprocessor yapadera, kapena momwe imagwirira ntchito imagwirizanitsidwa ndi zikwangwani zochokera ku ECU. Poterepa, muyenera kugwiritsa ntchito zamagetsi zamagalimoto kuyika dongosololi.

Zipangizo zamakono zopopera zimaphatikizapo zinthu zotsatirazi:

• Mpope wamagetsi wopanikiza mpaka bar 10;
• Mpweya umodzi kapena angapo opopera madzi (kuchuluka kwawo kumadalira chida chamtundu wonse ndi mfundo yogawa mayendedwe amadzi pazipilala);
• Wowongolera ndi microprocessor yomwe imayang'anira nthawi ndi kuchuluka kwa jakisoni wamadzi. Pampu yolumikizidwa nayo. Ndiyamika chinthu ichi, nthawi zonse mkulu-mwatsatanetsatane mlingo ndi anaonetsetsa. Ma aligorivimu ophatikizidwa ndi ma microprocessor ena amalola kuti makinawo azitha kusintha mosiyanasiyana mitundu yamagetsi yamagetsi;
• Tangi kuti madziwo azipopera mobwerezabwereza;
• Level sensor yomwe ili mu thanki iyi;
• Mapiko a kutalika kolondola ndi zovekera zoyenera.

Njirayi imagwira ntchito molingana ndi mfundo imeneyi. Wowongolera jakisoni amalandila zizindikilo kuchokera pakuyenda kwa mpweya (kuti mumve zambiri za momwe imagwirira ntchito ndi zovuta zake, werengani apa). Malinga ndi izi, pogwiritsa ntchito ma algorithms oyenerera, microprocessor imawerengera nthawi ndi kuchuluka kwa madzi opopera. Kutengera kusintha kwa dongosololi, mphukira imatha kupangidwa ngati malaya okhala ndi atomizer yopyapyala kwambiri.

Makina ambiri amakono amangopereka chikwangwani chotsegula mpope. Mu zida zodula kwambiri, pali valavu yapadera yomwe imasintha mlingowo, koma nthawi zambiri siyigwira ntchito moyenera. Kwenikweni, wowongolera amayamba pomwe mota ifika ku 3000 rpm. ndi zina zambiri. Musanayambe kukhazikitsa koteroko pagalimoto yanu, muyenera kukumbukira kuti opanga ambiri amachenjeza za machitidwe olakwika pamakina ena. Palibe amene adzapereka mndandanda mwatsatanetsatane, chifukwa chilichonse chimadalira magawo amagetsi.

Ngakhale ntchito yayikulu ya jakisoni wamadzi ndikuwonjezera mphamvu yamainjini, imagwiritsidwa ntchito pokhapokha ngati ozizira oziziritsa mpweya womwe umachokera ku chopangira chofiira.

Kuphatikiza pakukulitsa kutulutsa kwa injini, ambiri ali otsimikiza kuti jakisoniyo imatsukanso malo oyendera a silinda ndi thirakiti la utsi. Ena amakhulupirira kuti kupezeka kwa nthunzi mu utsi kumapangitsa kuti mankhwala azitha kuyika poizoni, koma pakadali pano, galimoto sidzafunika chinthu china chothandizira galimoto kapena dongosolo lovuta la AdBlue, lomwe mungawerenge . apa.

Kutulutsa madzi kumakhudza kokha pamakina othamanga kwambiri (kuyenera kutenthedwa bwino ndikuwuluka kwa mpweya kuyenera kuthamanga mwachangu kuti chinyontho chilowe muzipilala), komanso mokulira m'magawo amagetsi osinthika. Izi zimapereka makokedwe owonjezera komanso kuwonjezera pang'ono mphamvu.

Ngati injini mwachilengedwe ikulakalaka, ndiye kuti siyikhala yamphamvu kwambiri, koma sizingavutike chifukwa cha kuphulika. Pogwiritsa ntchito injini yoyaka moto mkati mwa turbo, jakisoni wamadzi woyikidwa patsogolo pa chowonjezeracho chimawonjezera mphamvu pochepetsa kutentha kwa mpweya womwe ukubwera. Ndipo pochita zazikulu kwambiri, makina oterewa amagwiritsa ntchito kusakaniza kwamadzi ndi methanol pamlingo wa 50x50.

Ubwino ndi kuipa

Chifukwa chake, makina opangira madzi amalola:

• Kulowetsa kutentha kwa mpweya;
• Kupereka kuzirala kowonjezerapo kwa zinthu zanyumba yoyaka;
• Ngati mafuta otsika kwambiri (otsika-octane) amagwiritsidwa ntchito, kupopera madzi kumawonjezera kukanika kwa injini;
• Kugwiritsa ntchito njira yomweyo yoyendetsa kumachepetsa mafuta. Izi zikutanthauza kuti ndimphamvu zomwezo, galimotoyo imatulutsa zowononga zochepa (zachidziwikire, izi sizothandiza kwambiri momwe galimoto ingachitire popanda chothandizira ndi njira zina zothetsera mpweya wa poizoni);
• Osati kokha kuwonjezera mphamvu, komanso zimapangitsa galimoto kutembenukira ndi makokedwe chinawonjezeka ndi 25-30 peresenti;
• Kuti pamlingo winawake zinthu zomwe zimayambira ndi kutulutsa injini;
• Sinthani kuyankha kwamphamvu ndi kuyankha;
• Bweretsani chopangira mphamvu kuti chizigwiritsa ntchito kuthamanga kwa liwiro la injini yochepa.

Ngakhale pali zinthu zambiri zothandiza, jakisoni wamadzi ndiwosafunika pagalimoto wamba, ndipo pali zifukwa zingapo zabwino zomwe opanga ma automaker sakugwiritsira ntchito popanga magalimoto. Ambiri mwa iwo ndichifukwa choti dongosololi lidachokera pamasewera. Mdziko la motorsport, chuma chamafuta chimanyalanyazidwa. Nthawi zina mafuta amafikira malita 20 pa zana. Izi ndichifukwa choti injini nthawi zambiri imabweretsedwera kuthamanga kwambiri, ndipo driver nthawi zambiri amalimbikira mpweya mpaka kuyima. Mwa njira iyi, zotsatira za jakisoni zimawonekera.

Chifukwa chake, izi ndizoyipa zazikulu zadongosolo:

• Popeza kuyikirako kumapangidwira kukonza magwiridwe antchito agalimoto zamasewera, izi zimangogwira pamphamvu yayikulu. Galimoto ikangofika pamlingo uwu, wowongolera amakonza mphindi ino ndikubaya madzi. Pazifukwa izi, kuti makinawo agwire bwino ntchito, galimotoyo iyenera kuyendetsedwa pamasewera. Pazovuta zochepa, injini imatha "kufungatira" kwambiri.
• Jekeseni wamadzi imachitika ndikuchedwa. Choyamba, njirayo imalowa mumayendedwe amagetsi, ma aligorivimu ofanana amayatsidwa mu microprocessor, ndipo mpopeyo imalandira chizindikiro kuti iyatse. Pampu yamagetsi imayamba kupopera madzi mumzere, ndipo pokhapokha pambuyo pake mphutsiyo imayamba kupopera. Kutengera ndikusintha kwa dongosololi, zonsezi zimatha kutenga pafupifupi millisecond imodzi. Ngati galimoto ikuyenda mwakachetechete, ndiye kuti kupopera mankhwala sikungakhale ndi mphamvu konse.
• Mu mitundu ndi nozzle limodzi, ndizosatheka kuwongolera kuchuluka kwa chinyezi chomwe chimalowa mu silinda inayake. Pachifukwa ichi, ngakhale kuli koyenera, machitidwe nthawi zambiri amawonetsa kuyendetsa kwamagalimoto osakhazikika, ngakhale atakhazikika bwino. Izi ndichifukwa cha kutentha kosiyanasiyana mu "miphika" iliyonse.
• M'nyengo yozizira, dongosololi limafunikira kuthira mafuta osati ndi madzi okha, komanso ndi methanol. Pakadali pano, ngakhale nyengo yozizira, madziwo amaperekedwa mwaulere kwa wokhometsa.
• Kuti mota uziyenda bwino, madzi obayidwa amafunika kuthiridwa, ndipo izi ndizowonjezera zina. Ngati mumagwiritsa ntchito madzi apampopi pafupipafupi, posakhalitsa madontho a laimu adzasonkhana pamakoma a malo olumikizirana (monga sikelo ya ketulo). Kukhalapo kwa ma particles olimba mgalimoto kumadzaza ndi kuwonongeka koyambirira kwa chipindacho. Pachifukwa ichi, distillate iyenera kugwiritsidwa ntchito. Poyerekeza ndi mafuta osafunikira (galimoto wamba sikuti imagwiritsidwa ntchito munjira zamasewera, ndipo lamuloli limaletsa izi pamisewu yaboma), kukhazikitsa kokhako, kukonza kwake ndikugwiritsa ntchito distillate (ndipo m'nyengo yozizira - chisakanizo cha madzi ndi methanol) sichabwino pazachuma ...

Kunena zowona, zofooka zina zimatha kukonzedwa. Mwachitsanzo, kuti unit yamagetsi igwire bwino ntchito pamtunda wapamwamba kapena pakatundu kambiri pa rpm yotsika, njira yokhazikitsira madzi imatha kukhazikitsidwa. Poterepa, ma jakisoni adzaikidwapo, imodzi pamitundu ingapo yodyera, monga mafuta ofanana.

Komabe, mtengo wa kuyika koteroko ukuwonjezeka kwambiri osati chifukwa cha zowonjezera zowonjezera. Chowonadi ndi chakuti jekeseni wa chinyezi ndiwomveka kokha pakakhala kayendedwe ka mpweya. Valavu yodyetsa (kapena zingapo pakusintha kwa mainjini) ikatsekedwa, ndipo izi zimachitika kwa mizere itatu, mpweya mu chitoliro suyenda.

Pofuna kuteteza madzi kuti asatulukire kwa osonkhanitsa pachabe (dongosololi silikuthandizira kuchotsa chinyezi chowonjezera chomwe chimadzaza pamakoma a wokhometsa), wowongolera amayenera kudziwa nthawi yanji komanso mphuno iti yomwe iyenera kugwira ntchito. Kukonzekera kovuta kumeneku kumafunikira zida zodula. Poyerekeza ndi kuchuluka kwakanthawi kwamagalimoto wamba, zoterezi sizoyenera.

Zachidziwikire, ndi bizinesi ya aliyense kukhazikitsa makina otere pagalimoto yanu kapena ayi. Talingalira za maubwino ndi zovuta za kapangidwe kameneka. Kuphatikiza apo, tikupangira kuwonera kanema mwatsatanetsatane wa momwe jekeseni wamadzi imagwirira ntchito:

Chiphunzitso cha injini yoyaka mkati: jakisoni wamadzi mu kapangidwe kake

Mafunso ndi Mayankho:

Kodi jekeseni wa Methanol ndi chiyani? Uku ndi kubaya madzi pang'ono kapena methanol mu injini yothamanga. Izi kumawonjezera kukana detonation wa mafuta osauka, amachepetsa umuna wa zinthu zoipa, kumawonjezera makokedwe ndi mphamvu ya injini kuyaka mkati.

Kodi jakisoni wamadzi a methanol ndi chiyani? Jekeseni wa methanol amaziziritsa mpweya wokokedwa ndi injini ndikuchepetsa mwayi wogogoda injini. Izi zimawonjezera mphamvu ya injini chifukwa cha kutentha kwakukulu kwa madzi.

Kodi Vodomethanol System imagwira ntchito bwanji? Zimatengera kusinthidwa kwadongosolo. Zothandiza kwambiri zimagwirizanitsidwa ndi ma jekeseni amafuta. Kutengera katundu wawo, methanol wamadzi amabayidwa.

Kodi Vodomethanol amagwiritsidwa ntchito bwanji? Izi zidagwiritsidwa ntchito ku Soviet Union mu injini za ndege kusanadze injini za jet. Methanol yamadzi idachepetsa kuphulika kwa injini yoyaka mkati ndikupangitsa kuyaka kwa HTS kukhala kosalala.
