I-valve yevacuum epholile ihlala isikhathi esingakanani?
Iswishi ye-vacuum vacuum epholile iyavula lapho i-heater ivuliwe futhi ivumele isipholile esivela enjinini ukuthi sigelezele kumongo we-heater. Lo moya ofudumele ophuma enjinini unikeza imfudumalo ngaphakathi emotweni. Umoya ugeleza ezimbotsheni futhi ungalawuleka ngokusebenzisa amaswishi eduze kwezihlalo zomshayeli nezabagibeli.
Ingxenye ye-vacuum yeswishi isiza ukulawula ukugeleza komoya ngezikhala. Ngokuhamba kwesikhathi, iswishi ye-vacuum vacuum epholile ingavaleka ngesipholile esidala noma imfucumfucu. Uma lokhu kwenzeka, i-derailleur ingase ingasebenzi kahle, okusho ukuthi ungaphatheka kabi ngokushayela uma ingashintshwa ngokushesha.
I-coolant vacuum valve switch inezingxenye ezintathu. Eyodwa ixhunywe ku-vacuum manifold, eyesibili ixhunywe ku-vacuum carburetor, kanti eyesithathu ixhunywe kwingcindezi ye-vacuum kumsabalalisi. Uma nje injini isebenza ngezinga lokushisa elijwayelekile, ivacuum ye-zero psi yenziwa kumsabalalisi. Ezinsukwini ezishisayo, lapho izinga lokushisa lenjini lingakhuphuka ngokushesha okukhulu, iswishi ishintsha umsabalalisi ukusuka ku-vacuum yembobo ukuya ku-vacuum ephindaphindiwe. Lokhu kwandisa isikhathi futhi kwandisa injini RPM.
Ngokushesha nje lapho lokhu kwenzeka, into epholile igeleza enjinini nakurediyetha, futhi isivinini sesiphephetha-moya siyanda. Izinga lokushisa lenjini liyehla ngokushesha libe sezingeni eliphephile. Uma injini isisezingeni elifanele, yonke into ibuyela kwesijwayelekile ize iqale ukushisa kakhulu noma iphinde iphole.
Iswishi ingahluleka ngokuhamba kwesikhathi, ngakho-ke uma lokhu kwenzeka, shintsha isivalo sevalvu epholile esikhundleni sikamakhenika onolwazi ngokushesha ngangokunokwenzeka. Kufanele futhi uqaphele izimpawu ezinikezwa yi-switch ngaphambi kokuthi yehluleke ukuze uzilungiselele futhi uyishintshe ngaphambi kokuthi yehluleke ngokuphelele.
Izimpawu zokuthi inzwa yevacuum valve epholile idinga ukushintshwa ihlanganisa:
- Ukushisa akufudumali ngendlela efanele
- Ukuvuza kwesipholile ngaphakathi emotweni noma ngaphansi kwemoto
- Umoya obandayo uvunguza ezimbotsheni ngisho noma iphinifa libonisa ukuthi kunikezwa umoya ofudumele.
Uma uhlangabezana nanoma yiziphi izinkinga ezingenhla, kungase kube isikhathi sokuthi imoto yakho ihlolwe. Yenza isikhathi sokubonana nomakhenikha oqinisekisiwe ukuze uxilonge futhi ulungise inkinga yakho.
