P0302 Cylinder 2 Misfire Kutholakele

Ikhodi yenkinga P0302 OBD-II Idatha ye

Kutholwe umlilo omubi kusilinda 2

Kusho ukuthini lokhu?

Le Khodi Yezinkinga Zokuxilonga (i-DTC) yikhodi yokudlulisela ejwayelekile, okusho ukuthi isebenza ezimotweni ezihlomele i-OBD-II. Noma kujwayelekile, izinyathelo ezithile zokulungisa zingahluka ngokuya ngohlobo lomkhiqizo / imodeli. Imikhiqizo yezimoto embozwe yile khodi ingabandakanya, kepha ayikhawulelwe ku-VW, Chevrolet, Jeep, Dodge, Nissan, Honda, Ford, Toyota, Hyundai, njll.

Isizathu sokuthi ikhodi ye-P0302 igcinwe emotweni yakho ye-OBD II yingoba imodyuli yokulawula amandla we-powertrain (PCM) ithole umlilo ongafanele kusilinda owodwa. U-P0302 ubhekise kwinombolo eyisilinda 2. Thinta umthombo wolwazi wemoto onokwethenjelwa lapho kutholakala khona u-cylinder number 2 wemoto okukhulunywa ngayo.

Lolu hlobo lwekhodi lungadalwa inkinga yokuphakelwa kukaphethiloli, ukuvuza okukhulu kwe-vacuum, ukungasebenzi kahle kohlelo lwe-exhaust (EGR), noma ukwehluleka kwenjini yemishini, kepha imvamisa kungumphumela wokungasebenzi kahle kwesistimu yokuhogela okuholela ekutheni kube nokuncane noma cha inhlansi. isimo.

Cishe zonke izimoto ze-OBD II zisebenzisa i-distributorless high-intensity spark ignition system, i-coil-spark plug (COP) ignition system. Ilawulwa yi-PCM ukuqinisekisa ukuthungela okunembile kwenhlansi nesikhathi.

I-PCM ibala okokufaka kusuka kunzwa yesikhala se-crankshaft, inzwa yesimo se-camshaft, kanye ne-sensor position position (phakathi kokunye, kuya ngemoto) ukuhlelela isu lesikhathi sokushisa.

Ngomqondo wangempela, inzwa yesikhundla se-camshaft kanye ne-crankshaft position sensor kubalulekile ekusebenzeni kohlelo lokuthungela i-OBD II. Kusetshenziswa okokufaka okuvela kulezi zinzwa, i-PCM ikhipha isignali yamandla kagesi edala amakhoyili okushisa okukhulu (imvamisa eyodwa kukasilinda ngamunye) ukuze afake umlilo ngokulandelana.

Njengoba i-crankshaft ijikeleza cishe kabili kunejubane le-camshaft (s), kubaluleke kakhulu ukuthi i-PCM yazi isikhundla sayo ngqo; kokubili ngokujwayelekile nangokuhlobana. Nansi indlela elula yokuchaza lesi sici sokusebenza kwenjini:

Isikhungo esiphezulu esifile (i-TDC) yindawo lapho i-crankshaft kanye ne-camshaft(ama) ziqondaniswe nepiston (yenombolo yesilinda sokuqala) endaweni yayo ephakeme kakhulu kanye nama-valve okungenisa (amasilinda inombolo yokuqala) avuliwe. Lokhu kubizwa ngokuthi i-compression stroke.

Ngesikhathi sokushaywa yisifo sokucindezelwa, umoya nophethiloli kudonselwa ekamelweni lomlilo. Kuleli qophelo, inhlansi yokushisa iyadingeka ukudala umlilo. I-PCM ibona isikhundla se-crankshaft ne-camshaft futhi inikezela ngesiginali yamandla kagesi edingekayo ukukhiqiza inhlansi enkulu yamandla kusuka kwikhoyili yokuthungela.

Ukusha kusilinda kusunduza i-piston ibuyele phansi. Lapho injini ihlaselwa yisifo sokucindezelwa futhi i-piston yokuqala iqala ukubuyela ku-crankshaft, ama-valve (ama) okudla ayavalwa. Lokhu kuqala ukushaya kokukhishwa. Lapho i-crankshaft yenza olunye uguquko, i-piston eyinombolo eyodwa ifinyelela endaweni yayo ephakeme futhi. Njengoba i-camshaft (ama) camshaft yenze uhhafu kuphela, i-valve yokudla ihlala ivaliwe futhi i-valve yokukhipha ivulekile. Phezulu kohlangothi lwe-exhaust, akudingeki ukuthi kube khona inhlansi yokushisa njengoba le stroke isetshenziselwa ukusunduza uphethiloli ophuma ngaphandle kwesilinda ngokuvula okwenziwe ama-valve (ama) evulekile evulekile angene kaningi.

Ukusebenza okujwayelekile kwekhoyili yokuthungela kufinyelelwa ngokuhlinzeka njalo kokuhlanganisiwe, okushintshwayo (okukhona kuphela lapho ukuvutha kuvuliwe) ugesi webhethri kanye ne-ground pulse ehlinzekwa (ngesikhathi esifanele) kusuka ku-PCM. Lapho i-ground pulse isetshenziswa kusekethe yekhoyili yokuthungela (eyinhloko), ikhoyili ikhipha inhlansi yokuqina okuphezulu (kufika ku-50,000 volts) ngengxenye yomzuzwana. Le spark enamandla kakhulu idluliselwa ngocingo lwe-spark plug noma i-shroud kanye ne-spark plug, ejikijelwa ekhanda le-cylinder noma i-multiple intake lapho ithinta khona ingxube enembile yomoya/yamafutha. Umphumela uba ukuqhuma okulawulwayo. Uma lokhu kuqhuma kungenzeki, izinga le-RPM liyathinteka futhi i-PCM iyalithola. I-PCM ibe isiqapha indawo ye-camshaft, indawo ye-crankshaft, kanye nokokufaka kwevoltage yempendulo yekhoyili ngayinye ukuze inqume ukuthi iyiphi isilinda okwamanje engalungile noma engasebenzi kahle.

Uma isilinda misfire singaphikisi noma sinzima ngokwanele, ikhodi ingahle ibonakale isalindile futhi isibani sesibonisi sokungasebenzi kahle (MIL) singakhanya kuphela lapho i-PCM ithola umlilo ongafanele (bese iphuma lapho ingekho). Uhlelo lwenzelwe ukwazisa umshayeli ukuthi injini engashisi kahle ngaleli zinga ingalimaza isiguquli samakhemikhali nezinye izinto zenjini. Lapho nje ukungqubuzana kwabantu kuphikelela futhi kukhula ngamandla, kuzogcinwa i-P0302 bese i-MIL isala ivuliwe.

Inombolo yomthetho: P0302

Izimo ezithanda ukugcinwa kwe-P0302 zingalimaza isiguquli se-catalytic kanye / noma injini. Le khodi kufanele ihlukaniswe njengebucayi.
