Uruhare rw'icyuma gipima aho Camshaft iherereye.
Uruhare rwa sensor y'aho imodoka iherereye ya camshaft:
1, sensor y'aho camshaft iherereye igomba gukusanya ikimenyetso cy'inguni gihinduka camshaft, no kwinjiza icyuma gicunga amashanyarazi (ECU), kugira ngo hamenyekane igihe cyo gutwika n'igihe cyo gutera, bityo imashini isohora n'iy'umwuka bibe bihari;
2, kugira ngo hakorwe igenzura ry’ishyirwa ry’amavuta mu buryo bukurikiranye, igenzura ry’igihe cyo gutwika no kugenzura igabanuka ry’umuriro. Byongeye kandi, ikimenyetso cy’aho camshaft iherereye gikoreshwa mu kumenya igihe cyo gutwika cya mbere moteri itangiye. Kubera ko sensor y’aho camshaft iherereye ishobora kumenya piston ya silindiri igiye kugera kuri TDC, yitwa sensor y’aho cyuma igaragara;
3, imiterere n'ihame ry'imikorere ya sensor y'aho camshaft iherereye n'aho crankshaft iherereye ni bimwe muri rusange, kandi akenshi bishyirwa hamwe, ariko aho buri moderi ishyirwa ni hatandukanye, ariko igomba gushyirwa mu mwanya ujyanye neza n'aho crankshaft iherereye, nka crankshaft, camshaft, flywheel cyangwa distributor;
4, koresha gusa sensor ya crankshaft. Sisitemu ya ECU ifite uburyo bwihariye bwo gutandukanya umuriro, gutandukanya urukurikirane rw'umuriro wa silinda, bitandukanye n'uburyo bwo gukoresha sensor ebyiri, ni ukuvuga ko, ikintu gikunzwe cyane ari "kubara", crankshaft ikora "1-3-4-2" mu mubare uhoraho w'impinduka. Bityo porogaramu ishobora "kubara" silindiri zitandukanye zo kurasa ku nguni imwe ya crankshaft, bityo sensor imwe irahagije.
Sensoreri y'aho Camshaft iherereye izwi kandi nka sensoreri y'igenzura rya silinda, kugira ngo itandukanye na sensoreri y'aho crankshaft iherereye (CPS), sensoreri y'aho camshaft iherereye muri rusange igaragazwa na CIS. Akamaro k'sensore y'aho camshaft iherereye ni ugukusanya ikimenyetso cy'aho camshaft iherereye cya valve ikagishyira muri ECU, kugira ngo ECU ibashe kumenya hagati ya silinda 1, kugira ngo ikore igenzura ry'ishyirwa rya lisansi mu buryo bukurikiranye, kugenzura igihe cyo gutwika no kugenzura deflagging. Byongeye kandi, ikimenyetso cy'aho camshaft iherereye gikoreshwa mu kumenya igihe cya mbere cyo gutwika moteri itangiye. Kubera ko sensoreri y'aho camshaft iherereye ishobora kumenya piston ya silinda iri hafi kugera kuri TDC, yitwa sensoreri y'aho silinda iherereye.
Umusaruro mubi wa sensor ya Camshaft
01 Ingorane mu gutangiza imodoka
Ingorane zo gutangiza imodoka ni ikimenyetso kigaragara cy'ikosa rya sensor ya camshaft. Sensor yo mu mwanya wa camshaft igena uko moteri ikurikirana. Iyo inaniwe, umurongo wo gutangiza imodoka uhinduka, bigatuma moteri itangirira bigoranye ndetse rimwe na rimwe ntitangire na gato. Iyi mimerere ntigira ingaruka gusa ku mikorere y'imodoka, ahubwo ishobora no kwangiza moteri. Kubwibyo, iyo bigaragaye ko imodoka igoye gutangira, ugomba kugenzura niba sensor ya camshaft ikora neza vuba bishoboka.
02 Intege nke zo kwihuta kw'umuvuduko
Kuba imodoka idashobora kwihuta ni ikimenyetso cy’uko sensor ya camshaft yangiritse. Iyo sensor ya camshaft inaniwe, ECU ntishobora kumenya neza impinduka mu mwanya wa camshaft. Ibi bizagira ingaruka ku buryo moteri yinjira n’isohoka ry’imodoka, bigatuma isohoka n’isohoka ry’imodoka hafi y’aho isohora umwuka rigabanuka. Kubera ko ibi bice by’ingenzi bidakora neza, imodoka izagira umunaniro iyo yihuta, cyane cyane iyo umuvuduko uri munsi ya 2500 RPM.
03 Kongera ikoreshwa rya lisansi
Ubwiyongere bw'ikoreshwa rya lisansi ni ikimenyetso kigaragara cy'uko sensor ya camshaft inaniwe. Iyo sensor ya camshaft ifite ikibazo, sisitemu ya lisansi y'imodoka ishobora kuba akajagari, bigatuma umunwa cyangwa injector itera lisansi inyura mu buryo butari bwo. Uku kuntu imodoka ikoresha lisansi mu buryo butunguranye ntibyongera gusa ikoreshwa rya lisansi, ahubwo bishobora no gutuma umuvuduko wa moteri udashobora kwiyongera, kandi imodoka ikagaragara nk'aho idafite imbaraga. Kubwibyo, iyo hagaragaye ubwiyongere budasanzwe bw'ikoreshwa rya lisansi mu modoka, bishobora kuba ikimenyetso cy'uko sensor ya camshaft ifite ikibazo.
04 Itara ry'imodoka
Itara ry'imodoka rikoresha ikosa risanzwe risobanura ko sensor nyinshi zishobora kuba zikora nabi. Cyane cyane iyo sensor ya camshaft yangiritse, iki kintu kiba kigaragara cyane. Sensors za camshaft ubusanzwe ni sensors eshatu za Hall, harimo insinga z'amashanyarazi za 12v cyangwa 5v, insinga z'ibimenyetso n'insinga zifatana. Iyo plug ikuwemo moteri igatangira, niba nta voltage y'ibimenyetso isohoka hagati y'umurongo w'ibimenyetso n'umurongo w'ibanze, ibi akenshi bivuze ko sensor yangiritse. Muri iki gihe, itara ry'imodoka rishobora kuza kugira ngo ryibutse umushoferi gukora igenzura rirambuye.
05 Umubiri urahinda umushyitsi mu buryo budasanzwe
Gutigita kudasanzwe k'umubiri ni ikimenyetso kigaragara cy'uko sensor ya camshaft idakora neza. Iyo habayeho ikibazo kuri sensor ya camshaft, ishami rigenzura moteri y'imodoka rishobora kutabasha gusoma neza imikorere ya moteri, bigatuma moteri idakora neza ndetse n'umubiri wayo ukanyeganyega ku buryo budasanzwe. Ubusanzwe uku gutitira kugaragara cyane iyo imodoka irimo kwihuta cyangwa igenda buhoro. Kugira ngo habeho umutekano mu gutwara, iyo ibibazo nk'ibyo bigaragaye, hagomba gukorwa igenzura ry'inzobere no kubungabunga ku gihe.
Niba ushaka kumenya byinshi, komeza usome izindi nkuru kuri uru rubuga!
Duhamagare niba ukeneye ibyo bicuruzwa.
