Ayini amabhande esikhathi?

Amabhande esikhathi amabhande awugqinsi enziwe ngenjoloba anamazinyo aqinile namagquma endaweni yawo yangaphakathi awasiza ukuba akhiye ngamasondo ama-crankshafts nama-camshafts. Asetshenziselwa ukunika amandla nokwenza lula imisebenzi kumaphampu amanzi, amaphampu kawoyela, namaphampu omjovo, njengoba kudingwa ukwakhiwa kwenjini. Asetshenziswa kakhulu ezinjinini ezivuthayo zangaphakathi ukwenza ama-valve enjini avuleke futhi avaleke ngendlela enesigqi ngokuhamba kwesikhathi.

 

Yiziphi ukusetshenziswa kwamabhande esikhathi?

Amabhande esikhathi asebenza kahle kakhulu anokusetshenziswa nemisebenzi elandelayo:

Idlala indima ebalulekile ekuqhubeni ngempumelelo inqubo yomlilo ngokulawula kahle ipiston namavalvu.

Ilawula ukusebenza kwe-valve ngokuxhuma i-crankshaft ne-camshaft ndawonye.

Inakekela ukuvulwa okuhlanganisiwe nokuvalwa kwama-valve enjini.

Iqeda isidingo samandla angaphandle ukuze isebenze ukuvula nokuvala ama-valve ngokusebenzisa amandla omshini wenjini yomlilo.

Omunye wemisebenzi ebalulekile kanye nokusetshenziswa kwamabhande wesikhathi ukuthi ivimbela i-piston ekushayeni ama-valve.

Naphezu kokuba ibhande elilodwa noma idivayisi, inomthelela omkhulu ekusebenzeni kwezingxenye eziningi njenge-upper balance shaft sprocket, i-sprocket ye-balance shaft ephansi, i-camshaft belt drive gear, igiya lokushayela ibhande lebhalansi, i-balance belt tensioner roller, ne-timing belt tensioner roller.

 

Ithini indlela yokusebenza yamabhande esikhathi?

Amabhande esikhathi avumelanisa umsebenzi wokuvala wokuvala kanye nezikhathi ze-crankshaft, i-camshaft, ne-exhaust valve. Isiza ekuthathweni kukaphethiloli nomoya ongena enjinini evuthayo, kanye nokulawula ivalvu yokukhipha umoya ukuze udedele intuthu noma i-exhaust ukuba iphume. Ibhande ligcina injini ixhumene futhi igcina ikhono layo nokukhiqiza.

 

Nini ukufaka esikhundleni ibhande lesikhathi?

Ukuvela kwalezi zimpawu kubonisa isidingo sokushintsha ibhande elidala neligugile futhi esikhundleni salo kufakwe ibhande lesikhathi elisha:

Amandla enjini ancishisiwe

Ukushisa ngokweqile kwenjini

Ukwenzeka kokudlidliza noma ukuzamazama enjinini

Ubunzima bokuqalisa umshini noma imoto

Ukuhlikihla noma imisindo ekhalayo evela ebhandeni

Kuqhuma umsindo wokukhiya enjinini

Amafutha avuzayo enjinini

Ukungahambi kahle ekusebenzeni kwesibani senjini
