Udindo wa sensa ya malo a Camshaft.
Udindo wa sensa ya malo a camshaft yamagalimoto:
1, sensa ya malo a camshaft ndi yosonkhanitsa chizindikiro cha camshaft champhamvu cha Angle, ndikulowetsa gawo lowongolera zamagetsi (ECU), kuti adziwe nthawi yoyatsira ndi nthawi yobayira, kuti mulowe ndi kutulutsa utsi;
2, kuti achite kuwongolera kotsatizana kwa jakisoni wa mafuta, kuwongolera nthawi yoyatsira moto ndi kuwongolera kutsika kwa mpweya. Kuphatikiza apo, chizindikiro cha malo a camshaft chimagwiritsidwa ntchito kuzindikira nthawi yoyamba yoyatsira moto pamene injini ikuyamba. Chifukwa chakuti sensa ya malo a camshaft imatha kuzindikira pistoni ya silinda yomwe ili pafupi kufika ku TDC, imatchedwa sensa yozindikiritsa silinda;
3, kapangidwe ndi mfundo yogwirira ntchito ya sensa ya camshaft position ndi sensa ya crankshaft position ndizofanana, ndipo nthawi zambiri zimayikidwa pamodzi, koma malo oyika a mtundu uliwonse ndi osiyana, koma ayenera kuyikidwa pamalo ogwirizana ndi crankshaft, monga crankshaft, camshaft, flywheel kapena distributor;
4, ingogwiritsani ntchito sensa ya crankshaft. Dongosolo la ECU lili ndi njira yapadera yosiyanitsira kuyatsa, kusiyanitsa kutsatizana kwa kuyatsa kwa silinda, ndikosiyana ndi njira yogwiritsira ntchito masensa awiri, ndiko kuti, mfundo yotchuka ndi "kuwerengera", crankshaft imayenda "1-3-4-2" mu kuchuluka kokhazikika kwa ma revolutions. Chifukwa chake pulogalamuyo imatha "kuwerengera" masilinda osiyanasiyana owombera pa ngodya yomweyo ya crankshaft, kotero sensa imodzi ndi yokwanira.
Sensa ya malo a Camshaft imadziwikanso kuti sensa yozindikiritsa silinda, kuti isiyanitse ndi sensa ya malo a crankshaft (CPS), sensa ya malo a camshaft nthawi zambiri imaimiridwa ndi CIS. Ntchito ya sensa ya malo a camshaft ndikusonkhanitsa chizindikiro cha malo a camshaft ya valve ndikuyiyika ku ECU, kuti ECU izindikire pakati pa silinda 1, kuti ichite kuwongolera kotsatizana kwa mafuta, kuwongolera nthawi yoyatsira moto ndi kuwongolera kuchotsa zipsera. Kuphatikiza apo, chizindikiro cha malo a camshaft chimagwiritsidwa ntchito kuzindikira nthawi yoyamba yoyatsira moto injini ikayamba. Chifukwa sensa ya malo a camshaft imatha kuzindikira pistoni ya silinda yomwe ili pafupi kufika ku TDC, imatchedwa sensa yozindikiritsa silinda.
Sensa ya Camshaft sigwira bwino ntchito
01 Kuvuta kuyambitsa galimoto
Vuto poyambitsa galimoto ndi chizindikiro chodziwikiratu cha vuto la sensa ya camshaft. Sensa yoyang'anira malo a camshaft imatsimikiza momwe injini imayatsira. Ikalephera, njira yoyatsira imasokonekera, zomwe zimapangitsa kuti injini iyambe movutikira ndipo nthawi zina osayamba konse. Vutoli silimangokhudza momwe galimoto imayambira, komanso lingayambitse kuwonongeka kwina kwa injini. Chifukwa chake, mukapeza kuti galimotoyo ndi yovuta kuyiyambitsa, muyenera kuwona ngati sensa ya camshaft ikugwira ntchito bwino mwachangu momwe mungathere.
02 Kufooka kwa Kuthamanga
Kulephera kwa galimoto kuthamanga ndi chizindikiro chodziwikiratu cha kuwonongeka kwa camshaft sensor. Pamene camshaft sensor yalephera, ECU singathe kuzindikira molondola kusintha kwa malo a camshaft. Izi zidzakhudza makina olowetsa ndi otulutsa injini, zomwe zimapangitsa kuti kulowetsa ndi kutulutsa kwa makina oyandikira utsi kuchepe. Chifukwa chakuti zigawo zazikuluzi sizigwira ntchito bwino, galimotoyo idzatopa ikathamanga, makamaka pamene liwiro lake ndi lochepera 2500 RPM.
03 Kuchuluka kwa kugwiritsa ntchito mafuta
Kuchuluka kwa mafuta omwe amagwiritsidwa ntchito ndi chizindikiro chodziwikiratu cha kulephera kwa sensa ya camshaft. Sensa ya camshaft ikalephera, makina amafuta a pakompyuta a galimoto amatha kusokonekera, zomwe zimapangitsa kuti nozzle kapena injector ipopere mafuta molakwika. Kusokonekera kumeneku sikuti kumawonjezera kugwiritsa ntchito mafuta kwa galimoto, komanso kungayambitse kuti liwiro la injini lisakwere bwino, ndipo galimotoyo imawoneka yofooka. Chifukwa chake, ngati mafuta a galimoto awonjezeka kwambiri, izi zitha kukhala chizindikiro chakuti sensa ya camshaft ndi yolakwika.
04 Chida chowunikira cholakwika cha galimoto
Kuwala kwa galimoto nthawi zambiri kumatanthauza kuti masensa angapo sakugwira ntchito bwino. Makamaka pamene sensa ya camshaft position yawonongeka, izi zimaonekera kwambiri. Masensa a camshaft nthawi zambiri amakhala masensa a Hall okhala ndi mawaya atatu, kuphatikizapo zingwe zamagetsi za 12v kapena 5v, zingwe za chizindikiro ndi zingwe zolumikizira. Pulagi ikatulutsidwa ndipo injini yayatsidwa, ngati palibe mphamvu ya chizindikiro pakati pa mzere wa chizindikiro ndi mzere woyambira, izi nthawi zambiri zikutanthauza kuti sensa yawonongeka. Pankhaniyi, nyali ya kuwonongeka kwa galimoto ikhoza kuyatsidwa kuti ikumbutse dalaivala kuti achite kafukufuku watsatanetsatane.
05 Thupi limagwedezeka modabwitsa
Kugwedezeka kwa thupi kosazolowereka ndi chizindikiro chodziwikiratu cha kulephera kwa sensa ya camshaft. Pakakhala vuto ndi sensa ya camshaft, gawo lowongolera injini ya galimotoyo silingathe kuwerenga bwino momwe injini ikugwira ntchito, zomwe zimapangitsa kuti injini isagwire bwino ntchito komanso kuti thupi lizigwedezeka molakwika. Kugwedezeka kumeneku nthawi zambiri kumaonekera kwambiri galimoto ikathamanga kapena ikuchedwa. Pofuna kuonetsetsa kuti kuyendetsa bwino, mavuto otere akapezeka, akatswiri ayenera kuyang'anitsitsa ndi kukonza nthawi yake.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&MAUXS zomwe zikulandiridwa kugula.
