Olunye ulwazi lwabalandeli beemoto

Ukuba ungumthandi wemoto, unokulangazelela ukufunda okuthile malunga nemoto ngobunzulu.Kwaye namhlanje siza kuthetha ngomahluko phakathi kwe-camshaft sensor kunye ne-crankshaft sensor kunye nomgaqo wokusebenza kwezi nzwa.

Yintoni umahluko phakathi kwe-camshaft sensor kunye ne-crankshaft sensor?

Yintoni isivamvo secrankshaft?

I-sensor ye-Crankshaft ngumqondiso oyintloko olawula ixesha lokutshiza amafutha kunye nokutshisa njengoko isetyenziselwa ukufumanisa isantya se-injini, indawo ye-crankshaft (i-Angle) uphawu kunye ne-cylinder yokuqala kunye ne-cylinder compression stroke stroke top of dead center signal.Njengenzwa yokuqukuqela komoya, yeyona nzwa iphambili kwinkqubo yolawulo esembindini ye-injini.Kwi-microcomputer elawulwa yi-electronic ignition system, isignali ye-engile ye-injini ye-crankshaft isetyenziselwa ukubala ixesha elithile lokutshisa, kwaye umqondiso wesantya usetyenziselwa ukubala kunye nokufunda i-engile yokutshisa kwangaphambili.

Yintoni i-camshaft sensor?

I-sensor yesikhundla se-Camshaft ikwabizwa ngokuba yi-sensor yesigaba, i-sensor ye-synchronous signal, isignali enkulu yokulawula i-injection ye-fuel kunye nexesha lokutshisa. Umsebenzi wayo kukubona uphawu lwe-camshaft Angle isikhundla, ukwenzela ukuchonga i-cylinder (efana ne-1 cylinder) i-piston TDC isikhundla. .

Yiyiphi indima abayidlalileyo enjinini ngokulandelelanayo?

Isivamvo sendawo yeCrankshaft, ubukhulu becala sisebenzisa isivamvo sokungeniswa kwamagnetic, sinamazinyo angama-60 thabatha amazinyo ama-3 okanye amazinyo angama-60 thabatha ivili elijoliswe kwizinyo eli-2.Izinzwa zeCamshaft, ubukhulu becala zisebenzisa izinzwa zeholo, ezinerotha yomqondiso enenotshi enye okanye iinotshi ezininzi ezingalinganiyo.Iyunithi yokulawula igcina ifumana kwaye ithelekisa amandla ombane wale miqondiso mibini.Xa zombini izibonakaliso ziphantsi kwamandla aphantsi, iyunithi yokulawula icinga ukuba i-top dead center ye-1 cylinder compression stroke ingafikelelwa yi-crankshaft Angle ethile ngeli xesha.Ukuba i-CKP kunye ne-CMP zombini zinamandla aphantsi ngokuthelekisa, iyunithi yolawulo inesalathiso sexesha lokutshisa kunye nexesha lokutofa.

Xa isignali ye-sensor ye-camshaft iphazamiseka, iyunithi yokulawula inokuqonda kuphela iziko eliphezulu elifileyo (TDC) ye-cylinder 1 kunye ne-cylinder 4 emva kokufumana uphawu lwendawo ye-crankshaft, kodwa akwaziwa ukuba yiyiphi enye ye-cylinder 1 kunye ne-4 ye-compression stroke. phezulu abafileyo iziko.Iyunithi yokulawula isenako ukutshiza ioli, kodwa ngesitofu esilandelelanayo kwinaliti ngexesha elifanayo, iyunithi yokulawula isenokuvutha, kodwa ixesha lokutshisa liza kulibaziseka kwi-Angle yokhuseleko lokungaqhubi, ngokubanzi kulibaziseke 1 5. Kweli nqanaba. , amandla e-injini kunye ne-torque iya kuncitshiswa, ukuqhuba ukuvakalelwa kokukhawuleza okungahambi kakuhle, kungekhona ukuya kwisantya esiphezulu esimiselweyo, ukusetyenziswa kwamafutha kwanda, ukungazinzi kokungasebenzi.

Xa isignali ye-sensor ye-crankshaft iphazamiseka, izithuthi ezininzi azikwazi ukuqala kuba inkqubo ayilungiselelwe ukusebenzisa i-camshaft sensor signal endaweni yoko.Nangona kunjalo, kwinani elincinci lezithuthi, ezifana neJetta 2 i-valve yejet yejet yombane eyasungulwa ngo-2000, xa isignali ye-sensor ye-crankshaft iphazamiseka, iyunithi yokulawula iya kutshintshwa ngumqondiso we-sensor ye-camshaft, kwaye injini inokuqalisa kwaye iqhube. , kodwa ukusebenza kuya kuncipha.

Ukuba ufuna ukufunda ngakumbi, nceda uzive ukhululekile ukuqhagamshelana nathi.I-YASEN ayikho kuphela i-camshaft sensor yase-China umenzi kodwa kunye ne-crankshaft sensor yase-China umenzi kwaye ngaphandle koko sinikezela ezinye izixhobo ze-auto ezifana ne-ABS sensors, i-air flow sensor, i-sensor ye-crankshaft, i-sensor ye-camshaft, i-sensor ye-truck, i-EGR Valve njalo njalo.
