Kungani izimoto zikadizili zikhipha intuthu emnyama?
Okuqukethwe
Kunombono oyiphutha ovamile phakathi kwabashayeli bakaphethiloli wokuthi izinjini zikadizili “zingcolile” nokuthi zonke zikhipha intuthu emnyama. Empeleni akunjalo. Bheka noma iyiphi imoto esebenza ngodizili futhi ngeke uyibone intuthu emnyama iphuma ku-exhaust. Lokhu empeleni kuwuphawu lokungakhathali kahle kanye nezingxenye ezinephutha, futhi akulona uphawu lokushiswa kwedizili ngokwayo.
Yini intuthu?
Intuthu emnyama kadizili empeleni ingudizili ongashi. Uma injini nezinye izakhi bezinakekelwa kahle, le nto ibingasha enjinini. Ngakho-ke ungazitshela zisuka nje ukuthi noma iyiphi injini kadizili ekhafula intuthu emnyama ayiwudli uphethiloli ngendlela okufanele iwudle ngayo.
Kubangelwa yini?
Imbangela enkulu yentuthu emnyama evela enjinini kadizili isilinganiso esingalungile somoya nophethiloli. Kuphakathi kokuthi uphethiloli omningi ujovwa enjinini, noma kufakwa umoya omncane kakhulu. Kunoma yikuphi, umphumela uyafana. Ngokuphawulekayo, abanye abashayeli empeleni bayakhokha ukuze izimoto zabo zilungiswe lokhu. Kubizwa ngokuthi "amalahle aginqikayo" futhi uzowabona ikakhulukazi kuma-pickup adizili (kanti ayabiza futhi ayamosha).
Esinye isizathu sale nkinga ukunganakekeli kahle komjovo, kodwa kunezinye ezimbalwa. Lokhu kubandakanya okulandelayo:
- Isihlungi somoya esivinjiwe noma esivalekile noma ukungena komoya
- Uphethiloli ongcolile (njengesihlabathi noma upharafini)
- Ama-camshaft agugile
- Ukulungiswa kwe-tappet okungalungile
- I-backpressure engalungile ekukhishweni kwemoto
- Isihlungi sikaphethiloli esingcolile/esivalekile
- Iphampu likaphethiloli elimele
Ekugcineni, ungase ubone intuthu emnyama enjinini kadizili ngoba umshayeli "uyayidonsa". Ngokuyisisekelo, isho ukuhlala egiyeni eliphezulu isikhathi eside. Uzoyiqaphela kakhulu ezimotweni ezinkulu emigwaqweni emikhulu, kodwa ungayibona ngezinga elithile nakwezinye izinjini zikadizili.
