Udindo wa sensor ya camshaft.
Udindo wamagalimoto a camshaft position sensor:
1, camshaft udindo sensa ndi kusonkhanitsa camshaft dynamic Angle siginecha, ndi kulowetsa magetsi unit unit (ECU), kuti adziwe nthawi poyatsira ndi jekeseni nthawi, kotero kudya ndi utsi zilipo;
2, kuti muzitha kuyendetsa jekeseni wotsatizana wamafuta, kuwongolera nthawi yoyatsira ndi kuwongolera kutentha. Kuphatikiza apo, chizindikiro cha camshaft chimagwiritsidwa ntchito kuzindikira mphindi yoyamba yoyatsira injini ikayamba. Chifukwa camshaft position sensor imatha kuzindikira pistoni ya silinda yomwe yatsala pang'ono kufika ku TDC, imatchedwa cylinder identification sensor;
3, kapangidwe ndi ntchito mfundo ya camshaft udindo sensa ndi crankshaft udindo sensa ali chimodzimodzi, ndipo nthawi zambiri anaika pamodzi, koma unsembe udindo wa chitsanzo aliyense ndi osiyana, koma ayenera kuikidwa mu malo a yeniyeni kufala ubale ndi crankshaft, monga crankshaft, camshaft, flywheel kapena distributor;
4, ingogwiritsani ntchito crankshaft sensa ECU dongosolo ali ndi ndondomeko yapadera kusiyanitsa poyatsira, kusiyanitsa yamphamvu poyatsira zinayendera, ndi wosiyana ndi njira yogwiritsira ntchito masensa awiri, ndiko kuti, wotchuka mfundo ndi "kuwerengera", crankshaft. imayendetsa "1-3-4-2" mu chiwerengero chokhazikika cha kusintha. Chifukwa chake pulogalamuyo imatha "kuwerengera" masilindala osiyanasiyana owombera pamtunda womwewo wa crankshaft, kotero kuti sensor imodzi ndiyokwanira.
Camshaft position sensor imadziwikanso kuti cylinder identification sensor, kuti tisiyanitse ndi crankshaft position sensor (CPS), camshaft position sensor nthawi zambiri amaimiridwa ndi CIS. Ntchito ya camshaft udindo sensa ndi kusonkhanitsa udindo chizindikiro cha camshaft valavu ndi athandizira kuti ECU, kuti ECU kudziwa pakati pamwamba ya yamphamvu 1 psinjika, kuti achite sequential jekeseni mafuta, nthawi poyatsira. control ndi deflagging control. Kuphatikiza apo, chizindikiro cha camshaft chimagwiritsidwa ntchito kuzindikira mphindi yoyamba yoyatsira injini ikayamba. Chifukwa camshaft position sensor imatha kuzindikira pistoni ya silinda yomwe yatsala pang'ono kufika ku TDC, imatchedwa cylinder identification sensor.
Camshaft sensor yoyipa imagwira ntchito
01 Kuvuta kuyambitsa galimoto
Kuvuta kuyambitsa galimoto ndi chiwonetsero chodziwikiratu cha cholakwika cha sensor ya camshaft. Sensor ya camshaft imatsimikizira kutsata kwa injini. Ikalephera, njira yoyatsira imachoka, zomwe zimapangitsa injiniyo kuti iyambe movutikira ndipo nthawi zina osayambanso. Izi sizimangokhudza momwe galimoto imayambira, komanso imatha kuwononga injini. Choncho, zikapezeka kuti galimotoyo ndi yovuta kuyamba, muyenera kufufuza ngati camshaft sensor ikugwira ntchito bwino mwamsanga.
02 Kufooka kwachangu
Kulephera kwa galimotoyo kuthamangira ndi chiwonetsero chodziwikiratu cha kuwonongeka kwa sensa ya camshaft. Pamene sensa ya camshaft ikulephera, ECU silingazindikire molondola kusintha kwa malo a camshaft. Izi zidzakhudza njira zogwiritsira ntchito komanso zowonongeka za injini, zomwe zimapangitsa kuti kuchepetsa kudya ndi kutulutsa mpweya wapafupi. Chifukwa chakuti zigawo zazikuluzikuluzi sizigwira ntchito bwino, galimotoyo imakhala ndi kutopa pamene ikuthamanga, makamaka pamene liwiro liri lochepera 2500 RPM.
03 Kugwiritsa ntchito mafuta ambiri
Kuchulukitsa kwamafuta ndi chiwonetsero chodziwikiratu cha kulephera kwa sensor ya camshaft. Sensa ya camshaft ikakhala yolakwika, makina amafuta agalimoto agalimoto amatha kukhala chipwirikiti, zomwe zimapangitsa kuti mphuno kapena jekeseni ipope mafuta osakhazikika. Kusokonezeka kwa jakisoni kumeneku sikungowonjezera mafuta agalimoto, komanso kungayambitsenso liwiro la injini, ndipo galimotoyo imawoneka yofooka. Choncho, ngati kuwonjezeka kwachilendo kwa mafuta a galimoto kumapezeka, kungakhale chizindikiro chakuti camshaft sensor ndi yolakwika.
04 Galimoto yoyaka moto
Kuwala kwagalimoto nthawi zambiri kumatanthauza kuti masensa angapo sakugwira ntchito bwino. Makamaka pamene camshaft udindo sensa yawonongeka, chodabwitsa ichi makamaka zoonekeratu. Masensa a Camshaft nthawi zambiri amakhala ndi masensa atatu a Hall Hall, kuphatikiza zingwe zamagetsi za 12v kapena 5v, zingwe zamasigino ndi zingwe zopumira. Pulagi ikatulutsidwa ndikuyambitsa injini, ngati palibe mphamvu yamagetsi yamagetsi pakati pa mzere wa chizindikiro ndi mzere woyambira, izi nthawi zambiri zimatanthauza kuti sensa yawonongeka. Zikatere, nyali yakulephera kwagalimoto imatha kubwera kuti ikumbutse dalaivala kuti afufuze mwatsatanetsatane.
05 Thupi limagwedezeka modabwitsa
Kugwedezeka kwa thupi kosazolowereka ndi chiwonetsero chodziwikiratu cha kulephera kwa sensa ya camshaft. Pakakhala vuto ndi sensa ya camshaft, gawo loyang'anira injini lagalimoto silingathe kuwerenga bwino momwe injiniyo ikugwirira ntchito, zomwe zimapangitsa kuti injini isasunthike komanso kugwedezeka kwa thupi. Jitter iyi nthawi zambiri imamveka bwino pamene galimoto ikuthamanga kapena kutsika. Pofuna kuonetsetsa chitetezo choyendetsa galimoto, mavuto oterewa akapezeka, kuyang'anira ndi kukonza akatswiri kuyenera kuchitika panthawi yake.
Ngati mukufuna kudziwa zambiri, pitilizani kuwerenga zolemba zina patsamba lino!
Chonde tiyimbireni ngati mukufuna zinthu zotere.
Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&MAUXS zolandiridwa kuti mugule.
