New Common Rail Injector Valve Assembly F00RJ02056 For 0445120142 0445120310 0445120325 Injector

KUTARIRA MAZHINJI EJENGO: TROUBLESHOOTING

Kugadzirisa matambudziko kunogona kuitwa kana injini iri kushanda uye kana yakadzimwa.Kugadzirisa dambudziko kana injini iri kushanda.

1 Verenga uye enzanisa voltage uye pulse nguva

Chiratidzo chejekiseni chinogona kuratidzwa uchishandisa oscilloscope.Nechinangwa ichi, batanidza mutsetse wekuyera kumutsara wechiratidzo, uye imwe mutsara kune yakakodzera pini yepasi.Neinjini ichimhanya, zvinokwanisika kuverenga kubva pamagetsi uye nguva yekupuruzira (nguva yekuvhura) kubva pachiratidzo chechiratidzo.Paunenge uchivhura iyo throttle valve, iyo pulse nguva inofanirwa kuwedzera panguva yekukurumidza nhanho, uye inogara ichimhanya injini (yakatenderedza 3000 RPM) inofanira kuwira kumashure, kana pazasi, kukosha kwekusaita.Mhedzisiro yemasilinda ega ega inogona kufananidzwa neimwe, uye izvi zvinogona kupa chiratidzo chezvingango kanganisa, semuenzaniso kusakwana kwemagetsi.

2 Edza kudzvanywa kwehuturu uye tarisa kupinza uye exhaust masisitimu ekuvuza Zvikamu

Mimwe miyedzo yakakosha kuyera kudzvanywa kwemafuta, kuitira kuona zvimwe zvinhu zvingave zviine mhosva (pombi yemafuta, sefa yemafuta, pressure regulator), uye kutarisa mapindiro neapopotera masisitimu ekudonha, kudzivirira kuyerwa kwenhema.Kana iyo sensor iine 2-pini yekubatanidza, inogona kunge iri inductive sensor.Muchiitiko ichi, kupikisa kwemukati, inogona kupfupika dunhu rekugadzira, uye chiratidzo chinogona kutsanangurwa.

Kuti uite izvi, bvisa plug yekubatanidza uye tarisa kupikisa kwemukati we sensor.Kana iyo yemukati yekupikisa kukosha iri 200 kusvika 1,000 ohms (zvichienderana nereferensi kukosha), sensor iri OK.Kana kukosha kuri 0 ohms, pane pfupi pfupi, uye mune imwe nyaya pane kuputsa.Muedzo wepfupi wedunhu kune furemu unoitwa uchishandisa ohmmeter kubva pane yekubatanidza pini kuenda kumotokari

pasi.Iko kukosha kwekupikisa kunofanirwa kuenda kune infinity.Muedzo uchishandisa oscilloscope unofanirwa kuguma nechiratidzo che sinus chesimba rakakwana.Panyaya yeJenareta yeHoro, chete chiratidzo chemagetsi muchimiro chesquare wave chiratidzo uye magetsi ekupa ndiwo anozoedzwa.Izvi zvinofanirwa kuguma nesquare wave chiratidzo zvinoenderana nekumhanya kweinjini.Tinofanira kudzokorora panguva ino kuti kushandisa ohmmeter kunogona kuparadza Horo jenareta.
