Kugwiritsa ntchito sensor ya injini

Ndi chitukuko chofulumira cha magalimoto, ogulitsa magalimoto padziko lonse lapansi ayesetsa kwambiri pantchito, mapulogalamu ndi zida zamagalimoto zamagalimoto, ndipo masensa ambiri adzagwiritsidwa ntchito pamagalimoto onse apamwamba. Pansipa tilemba ma sensor omwe amagwiritsidwa ntchito kwambiri:

1. Sensa ya malo a Crankshaft

Ntchito: Ndi sensor yofunika kwambiri pamakina oyatsira omwe amayendetsedwa ndi makompyuta, ndipo ntchito yake ndikuzindikira chizindikiro chapakati chakufa, chizindikiro cha liwiro la injini ndi siginecha ya crank angle, ndikuyika mu kompyuta kuti muwongolere kutsata kwa silinda ndi kupanga. nthawi yabwino kuyatsa nthawi.

Mtundu: electromagnetic induction Hall effect photoelectric effect mtundu

2. Camshaft position sensor

1. Ntchito: Sonkhanitsani chizindikiro cha valve camshaft ndikuyiyika ku ECU, kuti ECU idziwe malo omwe ali pamwamba pa tsinde la 1, ndiye kuti, perekani chizindikiro cha chiweruzo cha silinda (chizindikiro cha chiweruzo cha silinda ndicho maziko okha a ECU. kuwongolera nthawi ndi nthawi ya jakisoni wamafuta), kuti muzitha kuyang'anira nthawi yoyatsira ndikuwonongeka kwa kayendetsedwe ka jekeseni wamafuta, ndipo imagwiritsidwanso ntchito kuzindikira nthawi yoyamba kuyatsa pakadali pano.

Mtundu wa electromagnetic induction

Sensa imapangidwa ndi mutu wolowetsa ndi cholumikizira chopangidwa ndi maginito osatha ndi chitsulo chachitsulo cha gudumu lazizindikiro, ndipo pali kusiyana kwa pafupifupi 1mm pakati pa kumapeto kwa mutu wa induction ndi nsonga ya dzino la gudumu lachizindikiro. Pamene gudumu la chizindikiro likuzungulira, dzino la gudumu likayandikira ndikusiya mutu wolowetsa, mphamvu ya maginito yomwe imadutsa mu coil induction imasintha mofanana ndi concave ndi convex ya dzino ndi dzino, ndipo chizindikiro chonse cha AC chidzakhala. kulowetsedwa pa coil induction. Chizindikiro chikazungulira kamodzi, kumapeto kwa koyilo yolowera kudzapanga nambala yofananira ya ma siginecha a AC monga kuchuluka kwa magiya azizindikiro, ndipo ECU imatha kuwerengera liwiro la injini yamafuta ndi ngodya ya crankshaft malinga ndi kuchuluka ndi nthawi yazizindikiro. ndi mgwirizano pakati pa liwiro la injini ya mafuta.

Electromagnetic induction sensor ili ndi ubwino wamapangidwe osavuta komanso otsika mtengo, koma ilinso ndi zovuta kuti voteji yotulutsa imasinthasintha ndi injini.
