kulephera kwa mafuta owongolera mphamvu

kulephera kwa mafuta owongolera mphamvu Zimayambitsa kuti injini yoyaka mkati imayamba movutikira, imakhala ndi "kuyandama" liwiro lopanda ntchito, galimoto imataya mawonekedwe ake osinthika, nthawi zina kutulutsa mafuta kuchokera ku mapaipi amafuta. kawirikawiri, chowongolera mafuta (chidule cha RTD) chimayikidwa panjanji yamafuta ndipo ndi vacuum vacuum. Mumitundu ina yamagalimoto, RTD imadula mzere wobwereranso wamafuta amafuta. kuti muwone kuti kuwonongeka kwa dongosolo la mafuta ndi chowongolera cholakwika, muyenera kuchita macheke angapo osavuta.

Kodi mafuta owongolera ali kuti

kuti tipeze malo oyikapo chowongolera mafuta, tiyeni tiwone chomwe chiri komanso kuti ndi chiyani. Izi zidzakuthandizani kufufuza kwina ndi kufufuza.

Chinthu choyamba chimene muyenera kudziwa ndi chakuti pali mitundu iwiri ya RTDs - makina (akale chitsanzo) ndi magetsi (chitsanzo chatsopano). Koyamba, iyi ndi vacuum vacuum, yomwe ntchito yake ndikusamutsa mafuta ochulukirapo ndikubwerera ku thanki yamafuta kudzera pa hose yoyenera. Chachiwiri, ndi sensor yamafuta omwe amatumiza uthenga wofunikira ku kompyuta.

Kawirikawiri chowongolera chamafuta amafuta chimakhala panjanji yamafuta. Njira ina yowonjezeramo ndi payipi yobwerera mafuta yamagetsi. palinso njira - malo owongolera ali mu thanki yamafuta pagawo la mpope. M'machitidwe oterowo, palibe payipi yobwerera mafuta ngati yosafunikira. Kukhazikitsa koteroko kuli ndi ubwino wambiri, kuphatikizapo kuphweka kwa mapangidwe (palibe payipi yowonjezera), mafuta owonjezera samalowa m'chipinda cha injini, mafuta amawotcha pang'ono ndipo samasungunuka kwambiri.

Momwe mafuta oyendetsera mafuta amagwirira ntchito

Mwachidziwitso, valavu yachikale (yoikidwa pa magalimoto a petulo) ili ndi thupi lake, mkati mwake muli valve, nembanemba ndi kasupe. Pali malo atatu opangira mafuta m'nyumba. Kupyolera mu awiri a iwo, mafuta amadutsa muzitsulo zowongolera, ndipo chotsatira chachitatu chimagwirizanitsidwa ndi kuchuluka kwa kudya. Pakuthamanga kwa injini (kuphatikizapo osagwira ntchito), mphamvu ya mafuta mu dongosolo imakhala yochepa ndipo zonse zimapita mu injini. Ndi kuwonjezeka kwa liwiro, kuthamanga kofanana kumawonjezeka muzobweza zambiri, ndiko kuti, vacuum (vacuum) imapangidwa pamtundu wachitatu wa RTD, womwe, pamtengo wina, umagonjetsa mphamvu yotsutsa ya masika ake. izi zimapanga kuyenda kwa nembanemba ndi kutsegula kwa valve. Chifukwa chake, mafuta owonjezera amatha kulowa mugawo lachiwiri la chowongolera ndikubwerera ku tanki yamafuta kudzera pa hose yobwerera. Chifukwa cha algorithm yofotokozedwayo, chowongolera chamafuta nthawi zambiri chimatchedwanso cheki valavu.

Ponena za sensor yamafuta amafuta, ndizovuta kwambiri. Choncho, ili ndi magawo awiri - makina ndi magetsi. Gawo loyamba ndi nembanemba yachitsulo yomwe imasinthasintha pansi pa mphamvu yomwe imayambitsidwa ndi kukakamizidwa kwa mafuta. Kuchuluka kwa nembanemba kumadalira mphamvu yomwe mafuta amapangidwira. Gawo lamagetsi la sensor lili ndi magawo anayi amtundu wolumikizidwa molingana ndi dongosolo la Winston Bridge. Voltage imayikidwa kwa iwo, ndipo nembanemba ikapindika, mphamvu yotulutsa kuchokera kwa iwo imakhala yayikulu. Ndipo chizindikiro ichi chimatumizidwa ku ECU. Ndipo chifukwa chake, gawo lolamulira lamagetsi limatumiza lamulo loyenera ku mpope kuti lipereke kokha kuchuluka kwa mafuta ofunikira panthawiyo.

Ma injini a dizilo ali ndi mawonekedwe osiyana pang'ono owongolera mafuta. kutanthauza, amakhala ndi solenoid (koyilo) ndi tsinde lomwe limakhazikika pa mpira kuti liletse chakudya chobwerera. Izi zimachitika chifukwa chakuti injini ya dizilo yoyaka mkati imanjenjemera kwambiri panthawi yogwira ntchito, yomwe imakhudza kuvala kwa chowongolera chamafuta (petulo), ndiko kuti, pali chiwongola dzanja chokwanira komanso chokwanira cha ma hydraulic vibrations. Komabe, malo ake oyika ndi ofanana - mu njanji yamafuta a injini yoyaka mkati. Njira ina ndi pa nyumba ya pampu yamafuta.

Zizindikiro za chowongolera chowongolera mafuta osweka

Pali zizindikiro zisanu zoyamba za kulephera kwa mafuta (mitundu yonse iwiri) zomwe zingagwiritsidwe ntchito kuweruza kulephera kwathunthu kapena pang'ono kwa gawo lofunikirali. Komanso, zizindikiro zotsatirazi ndizofanana ndi magalimoto omwe ali ndi injini zoyatsira zamkati zamafuta ndi dizilo. Komabe, ndiyenera kutchula kuti zinthu zomwe zatchulidwazi zingakhale zizindikiro za kuwonongeka kwa zigawo zina za injini (pampu yamafuta, fyuluta yamafuta yotsekedwa), choncho m'pofunika kuti mufufuze bwinobwino kuti mudziwe bwino ntchito yake. Kotero, zizindikiro za kuwonongeka kwa mafuta oyendetsa mafuta ndi awa:

• Injini yoyambira yovuta. Izi nthawi zambiri zimasonyezedwa mu kuzunzika kwautali ndi woyambira ndi accelerator pedal wokhumudwa. Komanso, chizindikiro ichi ndi khalidwe lililonse kunja nyengo.
• Injini imayimitsidwa popanda ntchito. Kuti apitirize kugwira ntchito, dalaivala ayenera kuthira mpweya nthawi zonse. Njira ina ndi pamene injini yoyaka mkati imasiya, zosinthazo zimakhala "zoyandama", zosakhazikika, mpaka kuyimitsidwa kwa injini.
• Kutaya mphamvu ndi mphamvu. Mwachidule, galimoto "sikukoka", makamaka poyendetsa kukwera ndi / kapena kudzaza. mawonekedwe amphamvu agalimoto amatayikanso, imathamanga bwino, ndiye kuti, mukayesa kuthamangitsa, pali kutsika kwakukulu kwakusintha pamitengo yawo yapamwamba.
• Mafuta akutuluka pamizere yamafuta. Panthawi imodzimodziyo, kusintha ma hoses (clamps) ndi zinthu zina zapafupi sizithandiza.
• Kuchuluka kwa mafuta. Mtengo wake udzadalira pa zinthu zowonongeka komanso mphamvu ya injini yoyaka mkati.

Chifukwa chake, ngati chimodzi mwazizindikiro zomwe zili pamwambapa chikuwoneka, kuyezetsa kowonjezera kuyenera kuchitidwa, kuphatikiza kugwiritsa ntchito chojambulira cholakwika chamagetsi chomwe chilipo pamtima pakompyuta.

Kulakwitsa kwamafuta amafuta

Zolakwika Zowunika Zowongolera Mafuta a Mafuta

M'magalimoto amakono, sensa yamagetsi yamafuta imayikidwa ngati chowongolera. Ndi kulephera kwake pang'ono kapena kwathunthu, cholakwika chimodzi kapena zingapo zolumikizidwa ndi node iyi zimapangidwa pokumbukira gawo lamagetsi lamagetsi ICE. Nthawi yomweyo, kuwala kwa injini yakuyaka mkati kumayatsidwa pa dashboard.

Ngati pali kuwonongeka kwa DRT, ndiye kuti nthawi zambiri woyendetsa amakumana ndi zolakwika pansi pa nambala p2293 ndi p0089. Yoyamba imatchedwa "mafuta pressure regulator - kulephera kwamakina." Chachiwiri - "wowongolera kuthamanga kwamafuta ndi olakwika." Kwa eni magalimoto ena, chowongolera chofananiracho chikalephera, zolakwika zimapangidwira kukumbukira pakompyuta: p0087 "kupanikizika komwe kumayesedwa mu njanji yamafuta kumakhala kotsika kwambiri poyerekeza ndi komwe kumafunikira" kapena p0191 "chowongolera mafuta kapena sensa yamagetsi". Zizindikiro zakunja za zolakwika izi ndizofanana ndi zizindikiro za kulephera kwa wowongolera kuthamanga kwamafuta.

Kuti mudziwe ngati pali cholakwika chotere pamakumbukiro apakompyuta, autoscanner yotsika mtengo ithandizira Jambulani Chida Pro Black Edition. Chipangizochi chimagwirizana ndi magalimoto ambiri amakono okhala ndi cholumikizira cha OBD-2. Ndikokwanira kukhala ndi foni yamakono yokhala ndi pulogalamu yoyika matenda.

Mutha kulumikizana ndi gawo lowongolera magalimoto onse kudzera pa Bluetooth ndi Wi-Fi. Scan Tool Pro kukhala ndi 32-bit chip ndi kulumikiza popanda mavuto, amawerenga ndi kupulumutsa zonse kachipangizo deta osati mu injini kuyaka mkati, komanso mu gearbox, kufala, kapena kachitidwe wothandiza ABS, ESP, etc. itha kugwiritsidwanso ntchito kuyang'anira kuwerengera kwamafuta munthawi yeniyeni, yomwe imatumiza ku ECM yagalimoto poyang'ana macheke angapo.

Kuyang'ana chowongolera mafuta

Kuyang'ana kagwiridwe ka mafuta oyendetsa mafuta kumatengera ngati ndi makina kapena magetsi. wowongolera wakale mafuta a ICE zosavuta kufufuza. Muyenera kuchita motsatira algorithm iyi:

• pezani payipi yobwezera mafuta mu chipinda cha injini;
• yambitsani injini yoyaka mkati ndikuyisiya kwa mphindi imodzi, kuti isakhalenso yozizira, komanso osatentha mokwanira;
• kugwiritsa ntchito pliers (mosamala kuti musawononge !!!) kutsina payipi yobwerera mafuta yomwe yawonetsedwa pamwambapa;
• ngati injini yoyaka yamkati "inayenda" izi zisanachitike ndipo idagwira ntchito bwino, ndipo itatha kukanikiza payipiyo idagwira ntchito bwino, zikutanthauza kuti ndi wowongolera kuthamanga kwamafuta omwe adalephera.

Osatsina ma hoses amafuta a rabara kwa nthawi yayitali, chifukwa m'mikhalidwe yotere, pampu yamafuta imapangidwa, zomwe zimatha kuwononga nthawi yayitali!

Momwe mungadziwire ntchito pa jekeseni

Mu ma ICE amakono a jekeseni a petulo, choyamba, machubu achitsulo amaikidwa m'malo mwa mphira wamafuta a rabara (chifukwa cha kuthamanga kwamafuta komanso kudalirika komanso kulimba), ndipo kachiwiri, masensa amagetsi opangidwa ndi ma geji ovuta amayikidwa.

Chifukwa chake, kuyang'ana mphamvu yamagetsi yamafuta kumatsika ndikuwunika mphamvu yamagetsi kuchokera ku sensa pomwe mphamvu yamafuta yomwe imaperekedwa ikusintha, mwa kuyankhula kwina, kuwonjezeka / kuchepetsa liwiro la injini. Zomwe zidzamveketse bwino kuti chowongolera chowongolera mafuta sichikuyenda bwino kapena ayi.

Njira inanso yowonera ndi manometer. Chifukwa chake, choyezera chapakati chimalumikizidwa pakati pa payipi yamafuta ndi yoyenera. Musanachite izi, onetsetsani kuti mwachotsa payipi ya vacuum. Muyeneranso kudziwa kaye kuti injini yoyaka mafuta iyenera kukhala yotani mu injini yoyaka moto (idzakhala yosiyana ndi carburetor, jekeseni ndi injini za dizilo). Nthawi zambiri, pama jakisoni a ICE, mtengo wofananira ndi pafupifupi 2,5 ... 3,0 atmospheres.

Ndikofunikira kuyambitsa injini yoyaka mkati ndikuwonetsetsa, molingana ndi zowerengera pamagetsi okakamiza, kuti kupanikizika kuli kolondola. Kenako, muyenera kuzungulira pang'ono. Panthawi imodzimodziyo, kupanikizika kumatsika pang'ono (ndi magawo khumi a mlengalenga). Ndiye kupanikizika kumabwezeretsedwa. ndiye muyenera kugwiritsa ntchito pliers yemweyo kutsina payipi yamafuta obwerera, chifukwa chake kuthamanga kumawonjezeka mpaka 2,5 ... 3,5 atmospheres. Ngati izi sizichitika, ndiye kuti woyang'anirayo alibe dongosolo. Kumbukirani kuti mapaipi sayenera kutsina kwa nthawi yayitali!

Momwe mungayesere dizilo

Kuyang'ana kawongoleredwe ka mafuta pamakina amakono a Common Rail dizilo kumangoyesa kukana kwamagetsi mkati mwa coil control inductive coil. Nthawi zambiri, mtengo wofananira uli m'chigawo cha 8 ohms (mtengo weniweni uyenera kufotokozedwa m'mabuku owonjezera - zolemba). Ngati mtengo wotsutsa mwachiwonekere uli wotsika kwambiri kapena wapamwamba kwambiri, ndiye kuti wolamulirayo sali bwino. Mwatsatanetsatane diagnostics n'zotheka kokha mu zikhalidwe za utumiki galimoto pa maimidwe apadera, kumene osati masensa kufufuzidwa, koma lonse Common Rail mafuta dongosolo kulamulira dongosolo.

Zifukwa za kulephera kwa mafuta owongolera mafuta

M'malo mwake, palibe zifukwa zambiri zomwe mafuta owongolera amalephera. Tiyeni tiwalembe mwatsatanetsatane:

• Kuwonongeka kwanthawi zonse. Ichi ndiye chomwe chimayambitsa kulephera kwa RTD. kawirikawiri, izi zimachitika pamene galimoto ikuyenda pafupifupi 100 ... 200 makilomita zikwi. Kuwonongeka kwamakina kwa chowongolera kukakamiza kwamafuta kumawonetsedwa chifukwa nembanemba imataya mphamvu yake, valavu imatha kupindika, ndipo kasupe amafooka pakapita nthawi.
• Zigawo zolakwika. Izi sizichitika kawirikawiri, koma nthawi zambiri ukwati umapezeka nthawi zina pazinthu zopangidwa ndi opanga pakhomo. Choncho, ndi bwino kugula zida zopangira zoyambira kuchokera kwa opanga kunja kapena kuziyang'ana musanagule (onetsetsani kuti mukumvera chitsimikizo).
• Mafuta otsika kwambiri. Mu mafuta apanyumba ndi dizilo, mwatsoka, kupezeka kwa chinyezi, komanso zinyalala ndi zinthu zovulaza, zimaloledwa. Chifukwa cha chinyezi, matumba a dzimbiri amatha kuwoneka pazinthu zachitsulo za owongolera, zomwe zimafalikira pakapita nthawi ndikusokoneza ntchito yake yanthawi zonse, mwachitsanzo, masika amafooka.
• Zosefera mafuta otsekeka. Ngati pali zinyalala zambiri m'dongosolo lamafuta, zitha kuyambitsa kutsekeka, kuphatikiza RTD. Nthawi zambiri, muzochitika zotere, valavu imayamba kugwedezeka, kapena masika amatha.

kawirikawiri, ngati mafuta oyendetsa mafuta ndi olakwika, ndiye kuti sakukonzedwa, koma amasinthidwa ndi atsopano. Komabe, musanazitaya, nthawi zina (makamaka ngati zilipo), mukhoza kuyesa kuyeretsa RTD.

Kuyeretsa chowongolera mafuta

Musanasinthire ndi chinthu chatsopano chofananira, mutha kuyesa kuchiyeretsa, chifukwa njirayi ndi yosavuta komanso yopezeka kwa pafupifupi eni ake onse agalimoto m'magalasi. Nthawi zambiri, zoyeretsa zapadera za carburetor kapena zotsukira zama carb zimagwiritsidwa ntchito (madalaivala ena amagwiritsa ntchito chida chodziwika bwino cha WD-40 pazolinga zofanana).

Nthawi zambiri (komanso kupezeka kwambiri) ndikuyeretsa mauna a fyuluta, omwe amakhala pamalo opangira magetsi owongolera mafuta. Kupyolera mu izo, mafuta amaperekedwa ndendende ku njanji yamafuta. Pakapita nthawi, imakhala yotsekeka (makamaka ngati mafuta otsika kwambiri okhala ndi zonyansa zamakina, zinyalala zimatsanuliridwa mu thanki yagalimoto), zomwe zimabweretsa kuchepa kwa kutulutsa kwa owongolera komanso dongosolo lonse lamafuta.

Chifukwa chake, kuti muyeretse, muyenera kuthyola chowongolera chamafuta, kusokoneza, ndikugwiritsa ntchito chotsukira kuti muchotse ma depositi onse pa gridi ndi mkati mwa nyumba zowongolera (ngati kuli kotheka).

kuti mupewe kutsekeka kwa wowongolera kuthamanga kwamafuta, muyenera kusintha fyuluta yamafuta agalimoto motsatira malamulo.

Sewero lazowongolera mafuta

Pambuyo poyeretsa mauna ndi thupi lowongolera, ndikofunikira kuwaumitsa ndi air compressor musanayike. Ngati mulibe kompresa, ikani m'chipinda chofunda cholowera mpweya wabwino kwa nthawi yokwanira kusungunula chinyezi kuchokera kunja ndi mkati.

komanso imodzi zosowa kuyeretsa njira ndi ntchito akupanga unsembe pa galimoto utumiki. ndiko kuti, amagwiritsidwa ntchito poyeretsa ma nozzles apamwamba kwambiri. Ultrasound imatha "kutsuka" yaying'ono, yokhazikika kwambiri, kuipitsa. Komabe, apa ndikofunika kuyeza mtengo wa njira yoyeretsera komanso mtengo wa mesh yatsopano kapena chowongolera chowongolera mafuta chonse.
