RPM sensor

Iyo injini yekumhanyisa inotemerwa nemutongi zvichienderana nechiratidzo chinogadzirwa neiyo inductive crankshaft yekumhanyisa sensor.

Iyo sensor inoshanda negiya ferromagnetic impulse vhiri uye inogona kuiswa pane crankshaft mukati pulley kana flywheel. Mukati me sensor, iyo coil inovharwa yakatenderedza yakapfava simbi musimboti, imwe magumo ayo akabatana neanogara magineti kuti agadzire magineti wedunhu. Mitsetse yesimba remagineti inopinda mukati megiya chikamu chevhiri rekupusha, uye iyo magineti inovhara iyo coil mhepo inotenderera inoenderana nenzvimbo yehukama hwekupedzisira kwechiso che sensor uye mazino uye mikaha pakati pemazino pagumbo remhepo. . Sezvo mazino nehuro zvachinjana kupfuura iyo sensor, iyo magineti inoshanduka uye inoita kuti sinusoidal alternating inobuda voltage mune coil mhepo. Iyo voltage amplitude inowedzera nekuwedzera kutenderera kumhanya. Iyo inductive sensor inobvumidza iwe kuyera kumhanya kubva ku50 rpm.

Nerubatsiro rwe inductive sensor, zvinokwanisika kuziva imwe nzvimbo ye crankshaft. Kuchimaka, chinongedzo chinoshandiswa, chinoitwa nekubvisa mazino maviri anotevedzana pavhiri remhepo. Kuwedzera kwepakati pemazino notch kunotungamira kune chokwadi chekuti inochinjika voltage ine amplitude yakakura kupfuura voltage amplitude inokonzereswa nemazino asara uye manoche epakati evhiri rekupusha anogadzirwa mukupetwa kweiyo sensor coil.

Kana paine chete crankshaft kumhanya uye chinzvimbo sensor mune yekudzora sisitimu, kusavapo kwechiratidzo kunoita kuti zvisaite kuverenga nguva yekubatidza kana dosi yemafuta. Mune ino kesi, hapana kana imwe yekutsiva kukosha yakarongwa mu controller inogona kushandiswa.

Mune yakaoma yakabatanidzwa jekiseni-inopisa masisitimu, anotsiva masaini anotorwa kubva kune camshaft sensors mukusavapo kwechiratidzo kubva pakumhanya uye crankshaft chinzvimbo sensor. Injini yekudzora yakaderedzwa, asi zvirinani inogona kushanda mune inonzi Safe Mode.
