Kungani Ukushintshwa Kwebhande Lesikhathi Kungaba Kunzima

Izindlela zokushintsha ibhande lesikhathi ziyahlukahluka kuye ngohlobo lwebhande. Isevisi nokugcinwa kufanele kwenziwe ngokuhambisana nezincomo zomkhiqizi.

Izimoto eziningi namaloli amancane afakwe amabhande esikhathi. Izinjini eziguquguqukayo, ezaziwa nge-front wheel drive, zingaba nzima ukususa nokufaka esikhundleni sebhande lesikhathi.

Kunezinhlobo ezintathu zamabhande esikhathi

• Ibhande lesikhathi eline-camshaft eyodwa ephezulu
• Isikhathi ngama-camshaft amabili aphezulu
• Ibhande elinamazinyo amabili elinamakhamera amabili aphezulu

Ibhande lesikhathi eline-camshaft eyodwa ephezulu

Ukushintsha ibhande lesikhathi lekhamera elilodwa elingaphezulu kungaba umsebenzi onzima. Ezinye izimoto zinabakaki, amapayipi, noma amapayipi okupholisa ngaphambi kwekhava yesikhathi. Ukugcina i-camshaft ne-crankshaft kulayini kulula uma ushintsha ibhande lesikhathi.

Isikhathi ngama-camshaft amabili aphezulu

Amabhande esikhathi ekhamera angaphezulu kabili angaba nzima. Izimoto eziningi ezimakethe namuhla zine-cylinder head design lapho isitimela se-valve singena endaweni evuthayo nge-engeli yamashumi amane kuya kwamashumi ayisishiyagalombili. Lokhu kubaluleke kakhulu lapho ususa ibhande lesikhathi ngenxa yokuqondaniswa kwesitimela se-valve. Lapho ibhande lesikhathi lisuswa ku-camshaft engaphezulu ephindwe kabili, womabili ama-camshaft alayishwa ngaphambili ngeziphethu. I-camshaft eyodwa ingase ibe nomthwalo we-shaft, okubangela ukuthi i-camshaft ihlale endaweni ngenkathi ibhande likhishwa. Kodwa-ke, ngeke kube nomthwalo kwenye i-camshaft futhi i-shaft izojikeleza ngaphansi kwengcindezi yasentwasahlobo. Lokhu kungabangela ukuthi i-valve ihlangane ne-piston, okwenza i-valve igobe.

Ukuvimbela i-camshaft ukuthi ingajikelezi lapho ibhande lesikhathi lisuswa, ithuluzi lokukhiya ikhamera kufanele lisetshenziswe. Ithuluzi lokukhiya ikhamera likhiya womabili ama-camshaft futhi liwabambe ndawonye ukuze angazungezi.

Ibhande elinamazinyo amabili elinamakhamera amabili aphezulu

Uhlobo olunzima kakhulu lokushintshwa kwebhande lesikhathi, futhi kungaba nzima kakhulu ukulenza, ibhande lesikhathi lekhamera elingaphezulu eliphindwe kabili. Lolu hlobo lwebhande yibhande elilodwa elisetshenziswa ezinjinini zokucushwa kwe-av ezinamakhanda e-camshaft amabili. Izinjini eziningi ze-V-6 ezisebenza phezulu zingaba nalolu hlobo lwebhande. Uma ushintsha lolu hlobo lwebhande, kubalulekile ukuthi ube namathuluzi okukhiya amakhamera amabili njengoba kukhona amasethi amabili amakhanda angamasilinda enjinini.

Ezinjinini eziphambanayo, ibhande lesikhathi kungaba nzima ukulikhipha ngenxa yesikhala esilinganiselwe sokufinyelela ibhande. Kwezinye izimoto kulula ukususa ibhande phezulu enjinini, kodwa ezimotweni eziningi isondo nethayi lokuhlangana kufanele kukhishwe ngefender yangaphakathi uma iboshiwe ukuze ifinyelele kumabhawodi ekhava aphansi. ikhava yesikhathi. Izembozo eziningi zesikhathi manje seziwucezu olulodwa, okuholela ekukhishweni kwe-harmonic balancer etholakala ku-crankshaft.

Kwezinye izinjini, izinyusi zenjini ziphazamisa ukukhishwa kwebhande lesikhathi nokwenza kube nzima ukulikhipha ibhande. Kulesi simo, ukusekela injini nokuyivimbela ukuthi inganyakazi kuzosiza ekukhipheni nasekufakweni kwezigaxa zenjini, ezivame ukubizwa ngokuthi amathambo ezinja.

Amabhande esikhathi kufanele ashintshwe ngokuhambisana nezincomo zomenzi. Ukushintsha ibhande lesikhathi ngaphambi kokujwayelekile kungenzeka, kodwa akunconyiwe.

• Ukunakwa: Uma ibhande lesikhathi liphukile, qiniseka ukuthi uhlola injini ukuze uthole ukuthi injini enomsindo noma enomsindo. Futhi, lungisa isikhathi, faka ibhande elisha, futhi wenze ukuhlola ukuvuza ukuze uqiniseke ukuthi injini ikulungele ngempela ukusebenza okuvamile. I-AvtoTachki inezinsiza zokushintshwa kwebhande lesikhathi.
