Ngakhale kuti injini ya dizilo imakhala ndi zinthu zingapo, mbali imodzi yaing’onoyo imachititsa kuti injiniyo injenjemere. Kagawo kakang'ono kameneka ndi majekeseni amafuta, omwe ndi gawo lofunika kwambiri la jakisoni wamafuta agalimoto.
Makampani angapo agwiritsa ntchito madola apamwamba mu R&D kuti akwaniritse kachigawo kakang'ono kameneka chifukwa zimakhudza kwambiri magwiridwe antchito amagalimoto a injini ya dizilo.
Kaya m'magalimoto, m'mathiraki, -pamsewu, kapena -zolemera kwambiri, zojambulira zimakhala ndi gawo lalikulu pofotokozera momwe injini imagwirira ntchito potengera kuchuluka kwamafuta, kutulutsa mpweya, komanso moyo wautali.
Mu positi iyi, tiwona momwe ma jakisoni amafuta a dizilo amayendera, kuyambira ndi kudziwa-m'mene ma injini a dizilo amagwirira ntchito komanso momwe ma jakisoni amathandizira pakuyaka.
Kodi Ma injini a Dizilo Amagwira Ntchito Motani?
Magalimoto onse a petulo ndi dizilo amagwira ntchito paukadaulo woyatsira mkati. Amasiyana ndi momwe mafuta amabayidwira m'chipinda choyaka moto kuti azitha kuyaka.
Mumainjini amafuta, mpweya-wosakaniza wamafuta umayatsidwa mkati mwa chipinda choyaka ndi spark kuchokera pa spark plug.
Popeza mulibe ma spark plugs mu injini za dizilo, kuyaka kumachitika mafuta akalowetsedwa m'chipindamo panthawi yoponderezedwa. Pamene kupanikizana, kuthamanga ndi kutentha kwa mpweya mkati mwa chipindacho zimakhala zokwera kwambiri zomwe zimapangitsa kuti mpweya uziyaka-mtengo wamafuta.
Udindo wa Majekeseni a Dizilo
Ntchito ya jekeseni wa mafuta a dizilo ndikupereka mafuta olondola komanso oyezedwa bwino panthawi yoyenera. Zingamveke zosavuta, koma pali teknoloji yambiri yomwe imalowa mu izi.
Kupambana kwakukulu komwe kungapezeke pakukweza kwa injini ya dizilo kungabwere chifukwa cha kupita patsogolo kwaukadaulo wa ma jakisoni.
Injector iyenera kuwonetsetsa kuti mafuta amaperekedwa molondola ngakhale mutakhala ndi kuthamanga kwambiri komanso kutentha mkati mwa chipindacho. Kuthamanga kwa jekeseni kumatha kufika ku 36,000 PSIG (kupanikizika kwa mumlengalenga ndi pafupifupi 1 PSIG), ndipo kutentha kumatha kufika madigiri 1000 Fahrenheit.
Chifukwa cha kupita patsogolo kwaukadaulo wa jekeseni, mtengo wake ukhoza kuyimira 30% ya mtengo wonse wa injini.
Mapangidwe ndi uinjiniya wa ma jakisoni amakhudza kwambiri magwiridwe antchito a injini yokha.
Kugwira ntchito bwino kwamafuta, mawonekedwe a phokoso, ndi kuchuluka kwa mpweya zimakhudzidwa ndi ukadaulo wa jekeseni wamafuta ndi kapangidwe kake.
Kufotokozera Dongosolo Loyikira Mafuta a Dizilo:
Kuti mudziwe momwe mitundu yosiyanasiyana ya jakisoni wa dizilo imagwirira ntchito, ndikofunikira kumvetsetsa kachitidwe ka jakisoni wamafuta. Chigawo chilichonse mu dongosolo limodzi ndi jekeseni zimagwira ntchito yapadera pakuwonetsetsa kuti mafuta amabayidwa molondola. Nazi zigawo za injini ya dizilo:
1. Nozzle:
Pamtima pa jekeseni aliyense pali nozzle. Mphunoyo ndi kachigawo kakang'ono ka jekeseni kamene kamalowetsa mafuta mu nkhungu yabwino ya timadontho ting'onoting'ono tisanabayidwe m'chipinda choyaka. Atomizing mafuta ndi kofunika kuti uyake mwachangu komanso moyenera.
Mphunoyo ndi yolondola-yopangidwa kuti iwonetsetse kuti mafuta opopera sangafanane ndi kuyaka konse.
2. Vavu ya singano
Vavu ya singano, yomwe imadziwikanso kuti valavu yowongolera, imagwira ntchito limodzi ndi nozzle. Vavu ya singano imayendetsa kayendedwe ka mafuta potsegula ndi kutseka mphuno ya jekeseni. Lamuloli ndi lofunikira pakuwunika nthawi ndi mita, kulola injini kuti iziyenda bwino m'malo osiyanasiyana.
3. Solenoid
Solenoid ndi koyilo yamagetsi mkati mwa jekeseni yomwe imagwira ntchito ngati valavu. Solenoid imayankha zizindikiro zamagetsi kuchokera ku Electronic control unit (ECU), kutengera momwe imatsegula kapena kutseka jekeseni.
Ganizirani za ECU ngati chipangizo chokonzekera chomwe chimapereka malangizo ku zigawo zikuluzikulu za galimoto, kuphatikizapo majekeseni ndi makina opangira mafuta.
Solenoid imathandiza jekeseni kuti apereke mafuta enieni pa nthawi yoyenera, zomwe zimathandiza kuyaka bwino.
4. Pampu Yapamwamba-Yopanikizika
Monga momwe dzinalo likusonyezera, ntchito ya mpope wothamanga kwambiri-ndikupanga mphamvu yamphamvu kwambiri ndi kukanikiza mafutawo kuti athe kuthana ndi kuthamanga kwambiri mkati mwa chipindacho ndikubayabe mafuta a atomu. Pali makina opopera makina ndi makina a dizilo wamba njanji, iliyonse ili ndi zabwino zake.
5. Mizere ya Mafuta & Zosefera Mafuta
Mizere yamafuta ndi njira yolumikizira mapaipi ndi machubu omwe amanyamula mafuta kuchokera ku tanki kupita ku jekeseni. Cholakwika chilichonse kapena kuwonongeka kwa mizere yamafuta kungayambitse kutsika kwamphamvu komwe kumakhudza magwiridwe antchito a jekeseni.
Zosefera zamafuta zimachotsa zodetsa mumafuta popeza zowononga zimatha kuwononga zida zolondola monga majekeseni. Nthawi zambiri, kusefera kumachitika m'magawo angapo, kuyambira pa tanki kapena pampu yosinthira, ndikutsatiridwa ndi magawo oyambira ndi achiwiri akusefera.
Mitundu ya Majekeseni a Dizilo:
Pali mitundu ingapo ya jekeseni wamafuta, iliyonse ili ndi zabwino zake ndi zofooka zake. Mitundu ina ya jekeseni wamafuta yalembedwa pansipa:
Ma Injector a Unit: Izi zimaphatikizira mpope ndi nozzle kukhala gawo limodzi, zomwe zimapatsa mphamvu danga. Komabe, amabweretsa zovuta pakukonza ndi kukonza chifukwa cha zovuta zawo.
Common Rail Injector: Imagwira ntchito ndi-njanji yothamanga kwambiri yamafuta, majekeseniwa amathandizira kuti mafuta azitha kutumizidwa nthawi yake yolondola pamajekeseni angapo.
Majekeseni a Hydraulically Actuated: Pogwiritsa ntchito hydraulic pressure poyendetsa mphuno, majekeseniwa ndi okwera mtengo-ndiosavuta komanso osavuta kusiyana ndi amagetsi koma akhoza kusokoneza kulondola kwake.
Piezoelectric Injection: Kumangirira makhiristo a piezoelectric powongolera nozzle, amawonetsetsa kuperekedwa kwamafuta mosamalitsa komanso nthawi yake, ngakhale pamtengo wokwera kwambiri.
Kusamalira ma jekeseni anu amafuta:
Monga gawo lililonse lagalimoto, kukonza pafupipafupi komanso kokhazikika kwa ma jakisoni ndi ma jakisoni ndikofunikira kuti mukwaniritse bwino mafuta, mawonekedwe a phokoso omwe mukufuna, komanso kuwongolera mpweya. Umu ndi momwe mungasungire ma jakisoni:
Gwiritsani-mafuta abwino kwambiri: Onetsetsani kuti mafuta anu a dizilo alibe zowononga ngakhale mungakhale ndi zosefera ngati gawo la jekeseni wamafuta.
Sinthani zosefera mafuta: Zosefera zamafuta zimabwera ndi moyo wochepera wofotokozedwa ndi wopanga. Onetsetsani kuti zosefera zasinthidwa malinga ndi malingaliro a OEM. Zosefera zotsekeka zimakhudza kuyenda kwamafuta ndipo zimatha kuwononga majekeseni okwera mtengo.
Gwiritsani ntchito chotsukira chojambulira: Kuyeretsa nthawi ndi nthawi kwa jekeseni pogwiritsa ntchito chotsukira chovomerezeka chidzaonetsetsa kuti kuchotsedwa kwa zitseko ndi dothi ku jekeseni
Onetsetsani kuti majekeseni anu afufuzidwa ndikuthandizidwa mwaukadaulo: Kuyang'anitsitsa ndi kutumikiridwa nthawi zonse ndi akatswiri amakanika kungathandize kuzindikira mavuto pasadakhale
Kukulitsa Kuchita Kwa Injini Ya Dizilo Ndi Ma Injection Oyenera:
Kuzindikira mitundu yosiyanasiyana ya ma jakisoni amafuta a dizilo ndi makina ojambulira kumapatsa mphamvu eni magalimoto kuti ayamikire gawo lawo lofunikira pakusunga magwiridwe antchito amphamvu a injini za dizilo. Majekeseni ang'onoang'ono koma amphamvu awa ndi njira yopulumutsira makina anu amphamvu a dizilo!
Kwa eni ake a dizilo omwe akufunafuna ukadaulo wa jakisoni kapena zida zabwino, musayang'anenso Diesel Fuel Components Inc.
Timagwira ntchito mwaukadaulo pakukonza, kumanganso, ndikuyesa ntchito zamitundu yosiyanasiyana ya ma jakisoni a dizilo, mapampu, ndi magawo ena ofunikira a injini ya dizilo.
