Iindandatho zePiston
Izinto ezibalulekileyo ekufuneka ziqwalaselwe
Iiringi zePiston: Izinto ezibalulekileyo ezivala amagumbi okutsha, ezilawula ioyile, nezidlulisela ubushushu.
Iiringi ezintathu: Iringi nganye inendima eyahlukileyo—ukuvala ucinezelo, ukuhambisa ubushushu, kunye nokulawula ioyile.
Iimpawu zokusilela: Ukulahlekelwa ngumbane, ukusetyenziswa kakhulu kweoyile, umsi oluhlaza okwesibhakabhaka, okanye ukuqhuma kakubi.
Izisombululo zobungcali: Izixhobo ezisemgangathweni ophezulu kunye nobunjineli obuchanekileyo ziqinisekisa ukuqina nokusebenza kakuhle kwiimeko ezinzima.
Zithini iiRingi zePiston?
Iiringi zepiston ziibhanti zesinyithi ezijikelezileyo ezifakwe kwiipiston kwiinjini zomlilo zangaphakathi. Zahlulwe ukuze zivumele ukwanda kunye nokucutheka ngexesha lokusebenza. Ngokwesiqhelo zenziwe ngentsimbi ephosiweyo, intsimbi, okanye ii-alloys eziphambili, iiringi zepiston zanamhlanje zenzelwe ukumelana nobushushu obugqithisileyo, uxinzelelo, kunye nokungqubana.
Imisebenzi Ephambili
Ukutywina Igumbi Lokutsha: Ukuthintela ukuvuza kwegesi ngexesha lokutsha, ukuqinisekisa ukuba amandla aphuma kakhulu.
Ukudluliselwa kobushushu: Qhuba ubushushu ukusuka kwipiston ukuya eludongeni lwesilinda, uthintele ubushushu obugqithisileyo.
Ulawulo lweoyile: Lungisa ukusasazwa kweoyile eludongeni lwesilinda ukuze kuncitshiswe ukungqubana ngelixa uthintela ioyile engaphezulu ukuba ingangeni kwigumbi lokutsha.
Kutheni iiPistons zineMisongo Emithathu?
Uninzi lweenjini zisebenzisa amaringi amathathu e-piston, nganye ilungiselelwe umsebenzi othile:
Isangqa Soxinzelelo Esiphezulu: Iyamelana noxinzelelo kunye nobushushu obuphezulu, ivala iigesi zokutsha ukuze iphucule ukusebenza kakuhle kwenjini.
Isangqa sesibini sokucinezelwa: Sixhasa isangqa esiphezulu ekuvaleni iigesi kwaye sinceda ekuchitheni ubushushu.
Iringi yoLawulo lweOyile (Iringi yokuSkrapha): Ikhuhla ioyile egqithisileyo eludongeni lwesilinda ize ibuyisele ioyile kwi-crankcase, inciphisa ukusetyenziswa kunye nokukhutshwa komoya.
Kwenzeka ntoni xa iindandatho zePiston zingaphumeleli?
Iimpawu Eziqhelekileyo Zokusilela:
Ukulahlekelwa ngamandla enjini: Ukuxinana okuvuzayo kunciphisa ukusebenza kakuhle komlilo.
Ukusetyenziswa kakhulu kweoyile: Iiringi ezigugileyo zivumela ioyile ukuba ingene kwigumbi lokutsha.
Umsi oluhlaza okwesibhakabhaka ophuma kwi-exhaust: Ioyile evuthayo ivelisa umbala oluhlaza okwesibhakabhaka kwiigesi eziphuma kwi-exhaust.
Ukwanda kokukhutshwa kwegesi: Iiringi ezingasebenziyo zinegalelo ekukhutshweni kwegesi eninzi ye-hydrocarbon.
Injini ayisebenzi kakuhle: Ukucinezelwa okungalinganiyo kuphazamisa umjikelo wokutsha.
Iziphumo Zexesha Elide: Ukungahoyi iiringi zepiston ezigugileyo kunokukhokelela kumonakalo ongunaphakade eludongeni lwesilinda, ukungasebenzi kakuhle kwe-catalytic converter ngenxa yongcoliseko lweoyile, kunye nokulungiswa okanye ukutshintshwa kwenjini okubiza kakhulu.
