Chii chinoshanda se sensor ye camshaft yemota?
Chinongedzo chenzvimbo yecamshaft mudziyo unoona, unozivikanwawo sechinongedzo chechiratidzo chekubatanidza. Chinongedzo chekuisa chiratidzo checylinder chinopinza chiratidzo chenzvimbo yecamshaft kuECU uye chinoshanda sechiratidzo chikuru chekudzora kupisa.

Ma sensor e photoelectric crankshaft ne camshaft position akagadzirwa neNissan imhando yepamusoro yevagovanisi. Anonyanya kuve ne signal disc (kureva, signal rotor), signal generator, distributor, sensor housing, uye wiring harness connector.
Dhisiki rechiratidzo ndiro rinotenderera chiratidzo chesensor uye rinodzvanywa pashaft yesensor. Pamucheto pedyo nedhisiki rechiratidzo, kune mhete mbiri dzakakombama dzine maburi anotumira chiedza ane ma intervals akafanana. Pakati pawo, rin'i rekunze rine maburi 360 anotumira chiedza (缝隙), ane interval arc ye1. (Maburi anotumira chiedza ane 0.5, uye maburi emumvuri ane 0.5.) Anoshandiswa kugadzira crankshaft rotation angle uye speed signals； rin'i remukati rine maburi 6 anotumira chiedza (maburi akareba), ane interval arc ye60, anoshandiswa kugadzira top dead center signals yecylinder yega yega. Pakati pawo, gomba rimwe rectangular rine divi rakareba zvishoma, rinoshandiswa kugadzira top dead center signal yecylinder 1.
Jenareta yechiratidzo yakasungirirwa pahousing ye sensor. Inosanganisira jenareta yechiratidzo cheNe (speed and rotation angle signal), jenareta yechiratidzo cheG (top dead center signal), uye circuit yekugadzirisa masaini. Majenareta echiratidzo cheNe neG anoumbwa ne LED ne phototransistor (kana photodiode), ane ma LED maviri akatarisana ne phototransistors maviri zvakateerana.
Dhisiki rechiratidzo rinoiswa pakati pechiedza chinoburitsa chiedza (LED) netransistor inoteerera mufananidzo (kana photodiode). Kana gomba rinotumira chiedza padhisiki rechiratidzo richitenderera panzvimbo iri pakati peLED netransistor inoteerera mufananidzo, chiedza chinoburitswa neLED chichavhenekerwa patransistor inoteerera mufananidzo. Panguva ino, transistor inoteerera mufananidzo inotungamira uye collector yayo inoburitsa nhanho yakaderera (0.1 - 0.3V). Kana chikamu chemumvuri padhisiki rechiratidzo chichitenderera panzvimbo iri pakati peLED netransistor inoteerera mufananidzo, chiedza chinoburitswa neLED hachigone kuvhenekerwa patransistor inoteerera mufananidzo. Panguva ino, transistor inoteerera mufananidzo inogurwa uye collector yayo inoburitsa nhanho yepamusoro (4.8 - 5.2V).
Kana dhisiki rechiratidzo richitenderera nguva dzose, gomba rinotumira chiedza nechikamu chekuisa mumvuri zvichapfuura nepa LED kuti zvive pachena kana kuti zvine mumvuri. Muunganidzi we transistor inonzwa mufananidzo achaburitsa mazinga akakwira neakaderera. Kana shaft ye sensor ichitenderera ne crankshaft ne valve timing camshaft, gomba rinotumira chiedza nechikamu chekuisa mumvuri pa signal disc zvichapfuura ne LED. Chiedza chinoburitswa ne LED chichapenya nekuchinjana pa transistor inonzwa mufananidzo ye signal generator nekuda kwe light-mitting uye shading effect ye signal disc. Saka, pulse signal inoenderana nenzvimbo ye crankshaft ne valve timing camshaft ichagadzirwa mu signal sensor.
Sezvo crankshaft ichitenderera kaviri, sensor shaft inotyaira dhisiki rechiratidzo kuti itenderedze denderedzwa rimwe chete rakazara. Nokudaro, sensor yechiratidzo cheG ichagadzira zviratidzo zvepulse zvitanhatu. Sensor yechiratidzo cheNe ichagadzira zviratidzo zvepulse zve360. Nekuti arc yepakati pegomba rinotumira chiedza rechiratidzo cheG iri madhigirii makumi matanhatu, chiratidzo chepulse chinogadzirwa madhigirii zana nemakumi maviri ega ega ekutenderera kwecrankshaft. Nokudaro, chiratidzo cheG chinowanzonzi chiratidzo che120. Kuiswa kwedhizaini kunoita kuti chiratidzo che120 chigadzirwe madhigirii makumi manomwe pamberi penzvimbo yakasviba yepamusoro (BTDC70). Chiratidzo chinogadzirwa negomba rinotumira chiedza rine upamhi hwakareba zvishoma hunoenderana nemadhigirii makumi manomwe pamberi penzvimbo yakasviba yepamusoro yecylinder 1 yeinjini, kuitira kuti ECU igone kudzora angle yepamberi yekuisa mafuta uye angle yepamberi yekupisa. Nekuti arc yepakati pegomba rinotumira chiedza rechiratidzo cheNe iri 1 degree (gomba rinotumira chiedza rinotora madhigirii 0.5 uye gomba remumvuri rinotora madhigirii 0.5), muchikamu chega chega chepulse, mazinga akakwira neakaderera ega ega anotora angle imwe yecrankshaft. Zviratidzo zve360 zvinomiririra kutenderera kwemadhigirii 720 ecrankshaft. Madhigirii 120 ega ega ekutenderera kwecrankshaft, G signal sensor inogadzira chiratidzo chimwe chete uye Ne signal sensor inogadzira zviratidzo makumi matanhatu.
