Uma ungumthandi wezimoto, ungase ulangazelele ukufunda okuthile mayelana nezimoto ngokujula.Futhi namuhla sizokhuluma ngomehluko phakathi kwenzwa ye-camshaft ne-crankshaft sensor kanye nesimiso sokusebenza salezi zinzwa.
Uyini umehluko phakathi kwe-camshaft sensor ne-crankshaft sensor?
Iyini inzwa ye-crankshaft?
Inzwa ye-Crankshaft iyisiginali eyinhloko elawula isikhathi sokujova kukaphethiloli kanye nokuthungela njengoba isetshenziselwa ukuthola isivinini senjini, isignali yendawo ye-crankshaft (i-Angle) nesilinda sokuqala kanye nesignali ye-cylinder compression stroke top top dead center.Njengenzwa yokugeleza komoya, iyinzwa eyinhloko ohlelweni lokulawula oluphakathi kwenjini.Kusistimu yokuthungela kagesi elawulwa yi-microcomputer, isignali ye-engeli ye-crankshaft yenjini isetshenziselwa ukubala isikhathi esithile sokuthungela, futhi isignali yesivinini isetshenziselwa ukubala nokufunda i-Engeli eyisisekelo yokuthungela.
Iyini inzwa ye-camshaft?
I-Camshaft position sensor iphinde yaqanjwa nge-phase sensor, i-synchronous signal sensor, iyisiginali enkulu yokulawula umjovo kaphethiloli kanye nesikhathi sokuthungela. Umsebenzi wayo ukuthola isignali ye-camshaft Angle position, ukuze kunqunywe isilinda (njengesilinda esingu-1) indawo yepiston ye-TDC. .
Iyiphi indima abayidlalile enjinini ngokulandelana?
Inzwa yokuma ye-Crankshaft, ikakhulukazi esebenzisa inzwa yokungeniswa kazibuthe, enamazinyo angu-60 khipha amazinyo ama-3 noma amazinyo angu-60 kukhishwe isondo eliqondiwe kwamazinyo angu-2.Izinzwa zokuma kwe-Camshaft, ikakhulukazi ezisebenzisa izinzwa zehholo, ezinerotha yesiginali enenotshi eyodwa noma amanotshi ambalwa angalingani.Iyunithi yokulawula ilokhu yamukela futhi iqhathanisa i-voltage yalezi zimpawu ezimbili.Uma womabili amasiginali enamandla aphansi, iyunithi yokulawula icabanga ukuthi isikhungo esiphezulu esifile se-1 cylinder compression stroke singafinyelelwa nge-Angle ye-crankshaft ethile ngalesi sikhathi.Uma i-CKP ne-CMP kokubili kunamandla aphansi uma kuqhathaniswa, iyunithi yokulawula inereferensi yesikhathi sokuthungela kanye nesikhathi somjovo.
Uma isignali yenzwa ye-camshaft iphazamiseka, iyunithi yokulawula ingakwazi ukubona kuphela isikhungo esiphezulu esifile (TDC) se-cylinder 1 nesilinda 4 ngemva kokuthola isignali yendawo ye-crankshaft, kodwa akwaziwa ukuthi iyiphi i-cylinder 1 kanye ne-cylinder 4 i-compression stroke. isikhungo esiphezulu esifile.Iyunithi yokulawula isengakwazi ukufafaza uwoyela, kodwa ngomjovo olandelanayo kumjovo ngesikhathi esifanayo, iyunithi yokulawula isengakwazi ukuvutha, kodwa isikhathi sokuthungela sizobambezeleka ku-Engeli yokuphepha yokungaqhumisi, ngokuvamile ibambezeleke 1 5. Kuleli qophelo. , amandla enjini kanye ne-torque kuzoncishiswa, ukushayela umuzwa wokusheshisa okubi, hhayi kuze kufike isivinini esinqunyiwe, ukusetshenziswa kukaphethiloli kwanda, ukungazinzi kokungenzi lutho.
Uma isignali yenzwa ye-crankshaft iphazamiseka, izimoto eziningi azikwazi ukuqala ngoba uhlelo aluklanyelwe ukusebenzisa isignali yenzwa ye-camshaft esikhundleni salokho.Kodwa-ke, ngenani elincane lezimoto, njengeJetta 2 valve electric jet jet eyasungulwa ngo-2000, lapho isignali yenzwa ye-crankshaft iphazamiseka, iyunithi yokulawula izothathelwa indawo yisignali yenzwa ye-camshaft, futhi injini ingaqala futhi isebenze. , kodwa ukusebenza kuzokwehla.
Uma ufuna ukufunda okwengeziwe, sicela ukhululeke ukuxhumana nathi.I-YASEN ayiyona nje i-camshaft sensor yase-China umkhiqizi kodwa futhi i-crankshaft sensor yase-China nomkhiqizi we-crankshaft futhi ngaphandle kwalokho siphinde sinikeze ezinye izesekeli ze-auto ezifana nezinzwa ze-ABS, inzwa yokugeleza komoya, inzwa ye-crankshaft, inzwa ye-camshaft, inzwa yeloli, i-EGR Valve njalonjalo.
