Nthawi ya valve yosinthika - ndi chiyani? Kodi mphamvu ya injini ndi chiyani?

Ngati mukufuna kudziwa mosavuta ngati galimoto ili ndi nthawi yosinthira valve, muyenera kuyang'ana dzina la injini. Zimadziwika kuti n'zosatheka kukumbukira onse. Ndi zizindikiro ziti zomwe muyenera kuzidziwa? Odziwika kwambiri ndi V-TEC, Vanos, CVVT, VVT-i ndi Multiair. Aliyense wa iwo mu dzina amatanthauza mwina kuchuluka kwa mpweya, kapena kusintha kwa mavavu. Dziwani kuti nthawi yagalimoto ndi chiyani komanso momwe kusinthika kumakhudzira kuyendetsa. mudzabwera nafe

Kodi magawo a nthawi ya injini ndi chiyani?

Kodi munganene bwanji m'njira yosavuta? Dongosololi limayang'anira kutsegulidwa kwa mavavu olowetsa ndi kutulutsa. Izi zidzapititsa patsogolo kayendedwe ka mpweya pakati pa chipinda choyatsira moto ndi kulowetsedwa ndi kutulutsa mpweya wambiri. Izi, zimakupatsani mwayi wopeza mphamvu zambiri za injini popanda kugwiritsa ntchito, mwachitsanzo, turbocharger. Nthawi ya valve yosinthika imayendetsedwa m'njira zingapo. Komabe, udindo wawo nthawi zonse ndi kuwongolera nthawi zotsegulira ma valve mumayendedwe osiyanasiyana a injini.

Njira yosinthira nthawi ya valve ndi chinthu chofunikira kwambiri

CPFR, monga momwe izi zimatchulidwira mwachidule, ndi gawo lofunikira kwambiri pazithunzi zovuta. Njira yosinthira nthawi ya valve imatchedwanso phaser, variator, phase shifter, kapena phase shifter. Izi ndizofunikira makamaka kuwongolera camshaft ndikusintha malo ake aang'ono. Nthawi zambiri zimaphatikizidwa ndi njira yogawa. Izi zimatanthawuza kuphweka kwa makinawo komanso kukula kwake kochepa.

Njira yosinthira nthawi ya valve - zizindikiro za kusagwira ntchito

Monga zida zina zambiri zamagalimoto, KZFR nayonso imatha kuwonongeka. Kodi mungawazindikire bwanji? Sikuti nthawi zonse zimakhala zosamvetsetseka, ndipo nthawi zambiri zizindikiro za vutoli zimagwirizana ndi zovuta zina zomwe zingatheke. Komabe, pali zizindikiro. Ngati makina osinthira ma valve a injini yanu sakugwira ntchito bwino, mwina mukukumana ndi izi:

• kusinthasintha kwa liwiro lopanda ntchito;
• kugogoda mu injini;
• palibe kusintha kwa magwiridwe antchito a injini pama liwiro otsika;
• kuziziritsa injini ikayimitsidwa, mwachitsanzo, panjanji;
• vuto ndi kuyambitsa injini;
• phokoso ntchito ya ozizira pagalimoto.

Kuyendetsa ndi gudumu lowonongeka la valve - kuopsa kotani?

Kuphatikiza pa mfundo yakuti mudzamva mavuto omwe tawalemba poyendetsa galimoto, zotsatira zake zimakhala zovuta kwambiri. Kugwiritsira ntchito molakwika kwa njira ya nthawi ya valve kumakhudza shaft ya valve yokha. Musanyalanyaze kukonza nthawi yoyendetsa galimoto. Palibe chodikirira, chifukwa zotsatira zake zitha kukhala kuwonongeka kosasinthika kwa wodzigudubuza wokha. Ndiyeno dongosolo la nthawi ya valve yosinthika silingagwire ntchito bwino ndipo padzakhala gawo lina (lokwera mtengo!), Limene lidzafunika kusinthidwa.

Kodi njira yosinthira ma valve imagwira ntchito nthawi yayitali bwanji?

Pa chitsanzo cha limagwirira kuchokera BMW, i.e. Vanos, tikhoza kunena kuti kwa nthawi yaitali. M'mainjini oyendetsedwa bwino komanso osamalidwa bwino, zovuta siziwoneka mpaka zitadutsa makilomita 200. Izi zikutanthauza kuti m'magalimoto atsopano, mwiniwake sangasinthe chinthu ichi. Chofunikira ndi momwe injini imagwirira ntchito. Kusasamala kulikonse kudzawoneka m'njira yomwe imagwirira ntchito. Ndipo ndi chiyani chomwe chingasokonezeke mu dongosolo la magawo osiyanasiyana?

Kuwonongeka kwa nthawi ya valve sensor - zizindikiro

Kodi mungadziwe bwanji ngati valavu yosinthira nthawi ya solenoid ilibe vuto? Zizindikiro zowonongeka ndizofanana ndi kulephera kwa injini ya stepper. Zapangidwa kuti zikhalebe ndi liwiro losagwira ntchito. Pakakhala vuto ndi sensa (valenoid valve), ndiye kuti injiniyo ikakhala yopanda pake imakhala ndi chizolowezi choyimitsa. Zilibe kanthu ngati mumayendetsa mozizira, kapena injini yotentha. Chifukwa cha vutoli chikhoza kukhala kulephera mu dongosolo lolamulira kapena kulephera kwa makina. Choncho, ndi bwino kuyeza voteji pa valavu solenoid, ndiyeno m'malo zinthu.

Kusintha nthawi ya valve ndikusintha galimoto yonse

Mwinamwake mumaganiza kuti njira yoyendetsera valve ikhoza kulephera. Ndipo izi zikusonyeza kuti KZFR si yamuyaya. Choncho, nthawi ndi nthawi (kawirikawiri ndi kusintha kwa nthawi yachiwiri iliyonse), gudumu lokha liyenera kusinthidwa. Tsoka ilo, makina osinthira nthawi ya valve siwotsika mtengo kwambiri. M'magalimoto ena, mtengo wogula wa mbali zonse za galimotoyo, pamodzi ndi mpope wamadzi, sayenera kupitirira ma euro 700-80, komabe, pali zitsanzo zomwe lamba wa nthawi imodzi amawononga ndalama zosachepera 1500-200 euro, kotero izi ndizo. ndalama zambiri. Mtengo.

Kodi mungasamalire bwanji ma valve osinthika nthawi? Kuti mugwire bwino ntchito yanthawi ya valve yosinthika, ndikofunikira kusunga bwino gawo lamagetsi. Chofunika kwambiri ndikusintha kwamafuta, komwe kumayenera kuchitika chaka chilichonse kapena makilomita 12-15 aliwonse. Komanso kumbukirani kuti patatha nthawi yayitali osagwira ntchito, sayenera kupota injini pamwamba pa 4500 rpm, chifukwa mafuta omwe amayendetsa makinawo sangatuluke kuchokera ku poto yamafuta.
