Kodi zotsatira zake zidzakhala zotani pa galimoto ngati sensa ya camshaft yasweka?
Chojambulira cha camshaft chomwe chawonongeka chingayambitse mavuto pa kuyambika kwa injini, kugwedezeka panthawi yogwira ntchito, kuchepa kwa mphamvu, kuchuluka kwa mafuta omwe amagwiritsidwa ntchito, komanso kungayambitse alamu yowunikira cholakwika.
Zovuta Zoyambira ndi Kugwira Ntchito kwa Injini
Kuvuta poyatsira moto ndi chisokonezo: Sensor ikawonongeka, ECU singathe kudziwa bwino momwe silinda iliyonse ilili komanso gawo la camshaft, zomwe zimapangitsa kuti pakhale nthawi yoyatsira moto, yomwe imafunika kuyesera kangapo kuti iyambe, kapena kuchedwa kuyamba kapena kulephera kuyamba. Pa milandu yoopsa, panthawi yoyambira, pakhoza kukhala zochitika zobwerera m'mbuyo za crankshaft ndi intake manifold flashback.
Kuwonongeka kwa kukhazikika kwa ntchito ndi kulephera:
Kugwedezeka kwakukulu kosagwira ntchito: Mofanana ndi chizindikiro cha injini kulephera kugwira ntchito, kugwedezekako n'koonekeratu.
Injini imayima nthawi zambiri poyendetsa: Makamaka ikatentha, galimoto imatha kuyima mwadzidzidzi poyendetsa kapena powonjezera mafuta.
Kuyankha pang'onopang'ono: Mukaponda accelerator, mphamvu yotulutsa imachepa, ndipo nthawi zambiri, liwiro la injini liyenera kupitirira 2500 rpm kuti liwongolere.
Kuwonongeka kwa Mphamvu ndi Kuchuluka kwa Mafuta
Kuchepa kwakukulu kwa mphamvu yotulutsa: Chifukwa chakuti ECU silandira zizindikiro zenizeni za gawo la camshaft, nthawi yoyatsira mafuta ndi kuyatsa sizingagwirizane ndi ntchito ya silinda, zomwe zimapangitsa kuti injini ikhale yofooka, kuthamanga pang'onopang'ono, komanso kuyankha pang'onopang'ono pokwera kapena kudutsa. ECU ya mitundu ina ingachepetsenso liwiro lalikulu la injini kuti iteteze injini.
Kuchuluka kwa mafuta ndi mpweya woipa: Kulamulira kwa ECU pa kulowetsa mafuta sikolondola, kumayambitsa kulowetsa mafuta mopitirira muyeso kapena kulowetsa mafuta molakwika, ndipo kugwiritsa ntchito mafuta koyezedwa kungawonjezere ndi 15%-30%. Nthawi yomweyo, kuyaka kosakwanira kungayambitse utsi wakuda kuchokera ku chitoliro chotulutsa utsi, kuonjezera fungo la utsi, ndipo kungawonjezere katundu pa sensa ya okosijeni ndi chosinthira chamagetsi cha njira zitatu, ndikuwopseza kuwonongeka pakagwira ntchito kwa nthawi yayitali.
Chitetezo cha Dongosolo ndi Zoopsa Zomwe Zingakhalepo pa Makina
Kuyambitsa njira yoteteza zolakwika: Kuwala kwa injini kumakhala koyatsidwa nthawi zonse (nthawi zambiri kumagwirizana ndi ma code olakwika monga P0340), ndipo ECU idzalowa mu mode, kuchepetsa mphamvu yotulutsa, ndipo ikhoza kuletsa ntchito monga nthawi yosinthasintha ya valve (VVT). Pakadali pano, galimotoyo imatha kuyenda mtunda waufupi, koma magwiridwe antchito ake ndi ochepa kwambiri.
Zoopsa zomwe zingachitike chifukwa cha kuwonongeka kwa makina:
Kusalinganika kwa nthawi yoyatsira moto: Zingayambitse kuphulika, ndipo pakapita nthawi, zidzawononga silinda, pistoni, ndi zinthu zina.
Kuchuluka kwa kutopa kwa makina a valavu: ECU singathe kuwongolera bwino gawo la valavu, zomwe zingawonjezere kutopa kwa zida zina zokhudzana ndi makina.
Muzochitika zoopsa kwambiri pamene sensa ya crankshaft nayonso yalephera, galimotoyo ikhoza kulephera kuyamba kapena kuyima panthawi yogwira ntchito.
Disiki ya chizindikiro imayikidwa pakati pa diode yotulutsa kuwala (LED) ndi transistor ya photoelectric (kapena photodiode). Pamene dzenje lotumiza kuwala pa diski ya chizindikiro likuzungulira pakati pa LED ndi transistor ya photoelectric, kuwala komwe kumatulutsidwa ndi LED kudzawala pa transistor ya photoelectric, pamenepo transistor ya photoelectric imachita, ndipo chosonkhanitsa chake chimatulutsa mulingo wotsika (0.1-0.3V)； pamene gawo lophimba pa diski ya chizindikiro likuzungulira pakati pa LED ndi transistor ya photoelectric, kuwala komwe kumatulutsidwa ndi LED sikungawala pa transistor ya photoelectric, pamenepo transistor ya photoelectric imazima, ndipo chosonkhanitsa chake chimatulutsa mulingo wapamwamba (4.8-5.2V). Ngati diski ya chizindikiro izungulira mosalekeza, dzenje lotumiza kuwala ndi gawo lophimba lidzadutsa mosinthana pakati pa LED ndi transistor ya photoelectric, ndipo chosonkhanitsa cha transistor ya photoelectric chidzatulutsa mulingo wapamwamba ndi wotsika mosinthana. Pamene shaft ya sensa izungulira ndi crankshaft ndi valavu camshaft, dzenje lotumiza kuwala ndi gawo lophimba pa diski ya chizindikiro zidzadutsa pakati pa LED ndi transistor ya photoelectric, kuwala komwe kumatulutsidwa ndi LED kudzawala mosinthana pa transistor ya photoelectric ya jenereta ya chizindikiro, ndipo sensa ya chizindikiro idzapanga zizindikiro za pulse zogwirizana ndi malo a crankshaft ndi malo a valavu camshaft.
Popeza crankshaft imazungulira kawiri konse, sensa ya chizindikiro cha G imapanga zizindikiro 6 za pulse. Sensa ya chizindikiro cha Ne imapanga zizindikiro 360 za pulse. Chifukwa gawo lapakati la dzenje lotumiza kuwala la chizindikiro cha G ndi 60. Pa madigiri 120 aliwonse ozungulira crankshaft, chizindikiro cha pulse chimapangidwa. Chifukwa chake, chizindikiro cha G nthawi zambiri chimatchedwa chizindikiro cha 120. Kapangidwe ndi kuyika kwake kumatsimikizira kuti chizindikiro cha 120. chimapangidwa 70. (BTDC70.) patsogolo pa pakati pa injini yakufa. Chizindikiro chopangidwa ndi kutsegula kozungulira ndi mbali yayitali pang'ono chikufanana ndi 70. patsogolo pa pakati pa injini yakufa 1, kuti ECU izitha kuwongolera ngodya yoyendetsera mafuta ndi ngodya yoyendetsera kuyatsa. Popeza mtunda wa arc wa dzenje lotumizira kuwala kwa chizindikiro cha Ne ndi 1. (Dzenje lotumizira kuwala limatenga 0.5. ndipo dzenje loti liume limatenga 0.5.), mu pulse cycle iliyonse, milingo yapamwamba ndi yotsika iliyonse imatenga 1. ngodya yozungulira crankshaft, ndipo zizindikiro 360 zikuyimira kuzungulira kwa crankshaft kwa 720. Madigiri 120 aliwonse ozungulira crankshaft, sensa ya chizindikiro cha G imapanga chizindikiro chimodzi, ndipo sensa ya chizindikiro cha Ne imapanga zizindikiro 60.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
