Zvichakanganisa sei mota kana sensor ye camshaft ikatyoka?
Sensor yecamshaft yakakuvara inogona kukonzera matambudziko pakutanga kweinjini, kudedera panguva yekushanda, simba shoma, kushandiswa kwemafuta kwakawedzera, uye zvinogona kukonzera alarm yechiedza chefault.
Kusashanda zvakanaka kweInjini uye Kutangisa Kwayo
Kuoma kwekutanga uye kupinza kusina kurongeka: Mushure mekunge sensor yakuvara, ECU haigone kunyatsoona mamiriro e cylinder yega yega uye chikamu che camshaft, zvichikonzera nguva yekupinza isina kurongeka, zvichiratidzwa sekuti inoda kuyedza kakawanda kutanga, kana kutotanga kunonoka kana kutadza kutanga. Muzviitiko zvakakomba, panguva yekutanga, panogona kunge paine crankshaft reversal uye intake manifold flashback phenomena.
Kuderera kwekusashanda uye kugadzikana kwekushanda:
Kudedera kwakanyanya kusingashande: Kufanana nechiratidzo chekusashanda zvakanaka kweinjini, kudedera kuri pachena.
Kumira kweinjini nguva nenguva panguva yekutyaira: Kunyanya kana mota yadziya, inogona kungoerekana yamira panguva yekutyaira kana kuwedzera mafuta.
Kukurumidza kunonoka: Mushure mekutsika accelerator, simba rinobuda rinomira, uye kazhinji, kumhanya kweinjini kunofanirwa kudarika 2500 rpm kuti kuwedzere kunaka.
Kuderera Kwekushanda Kwemagetsi Uye Kushandiswa Kwemafuta
Kudzikira kukuru kwesimba rinobuda: Nekuda kwekuti ECU haina kugamuchira zviratidzo zvechikamu che camshaft chakarurama, nguva yekuisa mafuta uye yekupisa haigone kuwiriraniswa nekushanda kwe cylinder, zvichikonzera kushaya simba kweinjini, kukurumidza zvishoma nezvishoma, uye kupindura zvishoma nezvishoma panguva yekukwira kana kupfuura. ECU yemamwe mamodheru inogonawo kudzikamisa kumhanya kwakanyanya kweinjini kuchengetedza injini.
Kuwedzerwa kwekushandiswa kwemafuta uye kuburitswa kwemhepo: Kudzora kweECU kupinza mafuta hakuna kururama, zvichikonzera kupinza mafuta zvakanyanya kana kupinza mafuta zvisina kurongeka, uye kushandiswa kwemafuta kwakayerwa kunogona kuwedzera ne15%-30%. Panguva imwe chete, kupisa kusina kukwana kuchakonzera utsi hutema kubva papombi yekubuda, kunhuhwirira kweutsi kwakawedzera, uye kunogona kuwedzera mutoro pa sensor yeokisijeni uye three-way catalytic converter, nenjodzi yekukuvara kana ikashanda kwenguva refu.
Kudzivirirwa Kwemasisitimu Uye Njodzi Dzinogona Kuitika Pakugadzira Michina
Kushanda kwemodhi yekudzivirira kukanganisa: Mwenje weinjini unogara wakabatidzwa (kazhinji unoenderana nemakodhi ekutadza akadai seP0340), uye ECU ichapinda mumodhi, ichideredza simba rinobuda, uye inogona kudzima mabasa akadai se variable valve timing (VVT). Panguva ino, mota inogona kungofamba daro pfupi chete, asi mashandiro ayo akaganhurirwa zvakanyanya.
Njodzi dzinogona kuitika pakukuvadzwa kwemakanika:
Kusarongeka kwenguva yekubatidza: Izvi zvinogona kukonzera kuputika, uye nekufamba kwenguva, zvichakonzera kukuvara kwesirinda, pistoni, nezvimwe zvikamu.
Kuwedzera kwekushandiswa kwevharuvhu: ECU haigone kudzora chikamu chevharuvhu nemazvo, izvo zvinogona kuwedzera kupera kwezvikamu zvemakanika zvine chekuita nazvo.
Muzviitiko zvakanyanya apo sensor ye crankshaft inokundikanawo, mota inogona kutadza kutanga kana kumira zvachose panguva yekushanda.
Dhisiki rechiratidzo rinoiswa pakati pechiedza chinoburitsa chiedza (LED) netransistor yephotoelectric (kana photodiode). Kana gomba rinotumira chiedza padhisiki rechiratidzo richitenderera pakati peLED netransistor yephotoelectric, chiedza chinoburitswa neLED chichavhenekerwa patransistor yephotoelectric, ipapo transistor yephotoelectric inoitisa, uye muunganidzi wayo unoburitsa nhanho yakaderera (0.1-0.3V)； apo chikamu chekufukidza dhisiki rechiratidzo chinotenderera pakati peLED netransistor yephotoelectric, chiedza chinoburitswa neLED hachigone kuvhenekerwa patransistor yephotoelectric, ipapo transistor yephotoelectric inodzima, uye muunganidzi wayo unoburitsa nhanho yepamusoro (4.8-5.2V). Kana dhisiki rechiratidzo rikaramba richitenderera, gomba rinotumira chiedza nechikamu chekufukidza mumvuri zvichapfuura nepakati peLED netransistor yephotoelectric, uye muunganidzi wetransistor yephotoelectric achaburitsa nhanho yepamusoro neyakaderera. Kana mubato we sensor uchitenderera ne crankshaft ne valvu camshaft, gomba rinotumira chiedza nechikamu chemumvuri chiri pa signal disc zvichapfuura pakati pe LED ne photoelectric transistor, chiedza chinoburitswa ne LED chichapenya pa photoelectric transistor ye signal generator, uye signal sensor ichaburitsa pulse signals dzinoenderana nenzvimbo ye crankshaft nenzvimbo ye valvu camshaft.
Sezvo crankshaft ichitenderera kaviri, sensor yeG signal ichagadzira masaini matanhatu epulse. Iyo Ne signal sensor ichagadzira masaini mazana matatu nemakumi matanhatu epulse. Nekuti arc yepakati pegomba rinotumira chiedza rechiratidzo cheG i60. Pamadhigirii ese zana nemakumi maviri ekutenderera kwecrankshaft, chiratidzo chepulse chinogadzirwa. Naizvozvo, chiratidzo cheG chinowanzo nzi chiratidzo che120. Dhizaini uye kuiswa kunoita kuti chiratidzo che120. chigadzirwe 70. (BTDC70.) pamberi penzvimbo yepamusoro yecylinder yeinjini. Chiratidzo chinogadzirwa nerectangular opening ine divi rakareba zvishoma chinoenderana ne70. pamberi penzvimbo yepamusoro yecylinder 1 yeinjini, kuitira kuti ECU igone kudzora angle yepamberi yekuisa mafuta uye angle yepamberi yekupisa. Sezvo nzvimbo ye arc space yegomba rekutumira chiedza rechiratidzo cheNe iri 1. (Gomba rekutumira chiedza rinotora 0.5. uye gomba remumvuri rinotora 0.5.), mu pulse cycle yega yega, mazinga epamusoro neakaderera ega ega anotora 1. crankshaft rotation angle, uye 360 signals zvinomiririra 720. kutenderera kwecrankshaft. 120. degrees yega yega yekutenderera kwecrankshaft, G signal sensor inogadzira chiratidzo chimwe chete, uye Ne signal sensor inogadzira 60 signals.
