Emkhakheni wobunjiniyela bezimoto, yonke ingxenye idlala indima ebalulekile ekugcineni injini isebenza kahle. Uchungechunge lwesikhathi luyinto ebaluleke kakhulu kodwa evame ukunganakwa. Lesi sihloko sihlose ukucacisa injongo nokubaluleka kochungechunge lwesikhathi olunezimbobo ezimbili, sixoxe ngezinzuzo zalo nokuthi kungani lusetshenziswa kabanzi ezinjinini zesimanje.
Yazi izisekelo:
Ngaphambi kokuhlola injongo yeketanga lesikhathi elijikelezayo elikabili, kubalulekile ukuba nokuqonda okuyisisekelo ngomsebenzi walo. Iketanga lesikhathi lixhuma i-crankshaft nama-camshaft, liwagcine ehambisana. Njengoba i-crankshaft ijikeleza, iketanga lesikhathi lilawula ukuvulwa nokuvalwa kwamavalvu enjini, okwenza kube lula ukungena komoya nophethiloli kanye nokuxoshwa kwamagesi okukhipha umoya.
Yini ehlukanisa uchungechunge lwesikhathi olunezimbobo ezimbili:
Nakuba iketanga lesikhathi elijwayelekile lenza umsebenzi walo ohlosiwe ngempumelelo, iketanga lesikhathi eliphindwe kabili liyaliphakamisa. Isici esiphawulekayo seketanga lesikhathi eliphindwe kabili ukwakheka kwalo, lapho iketanga liqukethe imigqa emibili yama-roller amancane axhumene. Lo mklamo omusha wenzelwe ukunciphisa ukuxega nokunciphisa ingozi yokwehluleka kweketanga lesikhathi, ukuqinisekisa ukunemba kwesikhathi okuhle kakhulu nokwandisa isikhathi sokuphila kwenjini.
Ukuqina Okuthuthukisiwe kanye Namandla:
Enye yezinhloso eziyinhloko zeketanga lesikhathi eligoqeka kabili ukubhekana nokwelulwa kanye nokuguguleka kweketanga. Ngokuhamba kwesikhathi, iketanga lesikhathi elijwayelekile linganwebeka, okuholela ekuthini isikhathi se-valve singanembile, ukulahlekelwa amandla, kanye nomonakalo wenjini ongaba khona. Ngokuphambene nalokho, ukuba khona kwemigqa emibili yama-roller kuketanga lesikhathi eligoqeka kabili kusabalalisa umthwalo kahle, kunciphisa ukwelulwa kweketanga futhi kwandise ukuqina kwalo lonke.
Thuthukisa ukunemba kwesikhathi:
Ezinhlelweni zokusebenza kahle kakhulu, isikhathi esinembile sibalulekile ukuze kuthuthukiswe ukusebenza kwenjini. Amaketanga okuhlala e-dual roller asebenza kahle kakhulu ekugcineni isikhathi esinembile se-valve ngenxa yomklamo wawo wokunciphisa ukugoba kweketanga. Ngokunciphisa amathuba okugoba, ama-twin rollers aqinisekisa ukuthi i-crankshaft ne-camshaft zihlala zihambisana, okuthuthukisa ukusebenza kahle kwenjini kanye nokukhishwa kwamandla.
Nciphisa umsindo nokudlidliza:
Ukudlidliza kweketanga nomsindo kungaba yinkinga engamukeleki enjinini futhi kuthinte ulwazi lokushayela lulonke. Inzuzo eyengeziwe yamaketanga e-double roller timing yikhono lokunciphisa ukudlidliza ngenxa yokwanda kwendawo yokuxhumana enikezwa umklamo we-roller. Ngenxa yalokho, umsindo wenjini nokudlidliza kunciphisa kakhulu, okusiza injini ukuthi isebenze kahle nangokuthula.
Amaketanga okuhamba ngama-double roller adlala indima ebalulekile ekwakhiweni kwezinjini zesimanje, athuthukisa ukuqina, athuthukisa ukunemba kwesikhathi futhi anciphise amazinga omsindo nokudlidliza. Umklamo wama-double roller uxazulula ngempumelelo inkinga yokwelulwa kwamaketanga, ukuqinisekisa ukunemba nokuthembeka. Ngezinzuzo zawo kanye nokusetshenziswa kabanzi phakathi kwabenzi bezimoto, inhloso yeketanga lokuhamba ngama-double roller ngokusobala iwukwenza ngcono ukusebenza kwenjini nokuphila kwayo. Ngakho-ke ngesikhathi esizayo lapho uqala injini yakho, yazisa ukusebenza kahle nokuthembeka okungalethwa yiketanga lokuhamba ngama-dual roller emotweni yakho.
