Imisesane yePiston
Izinto eziphambili zokuThatha
Amakhonkco ePiston: Amacandelo abalulekileyo atywina amagumbi okutsha, alawule ioyile, kwaye adlulise ubushushu.
Izangqa eziThathu: Iringi ngalinye lisebenza indima eyahlukileyo—ukutywinwa koxinzelelo, ukuhanjiswa kobushushu kunye nolawulo lweoyile.
Iimpawu zokungaphumeleli: Ukulahlekelwa kwamandla, ukusetyenziswa kweoli ngokugqithiseleyo, umsi oluhlaza okwesibhakabhaka, okanye imililo engafanelekanga.
Izisombululo zobuNgcali: Izinto ezikumgangatho ophezulu kunye nobunjineli obuchanekileyo buqinisekisa ukuqina kunye nokusebenza kwiimeko ezinzima.
Yintoni amakhonkco ePiston?
Izangqa zepiston zizibhanti zentsimbi ezijikelezayo ezifakwe kufutshane neepiston kwiinjini zokutsha zangaphakathi. Ziyahlulahlulwe ukuvumela ukwandiswa kunye nokuncipha ngexesha lokusebenza. Ngokuqhelekileyo zenziwe ngentsimbi etyhidiweyo, intsimbi, okanye i-alloys ephucukileyo, amakhonkco episton anamhlanje ayenzelwe ukumelana namaqondo obushushu agqithisileyo, uxinzelelo kunye nokukhuhlana.
Imisebenzi yokuqala
Ukutywina iGumbi lokutsha: Thintela ukuvuza kwerhasi ngexesha lokutsha, uqinisekisa ubuninzi bamandla ombane.
Ukutshintshwa kobushushu: Ukuqhuba ubushushu obuvela kwipiston ukuya eludongeni lwesilinda, ukuthintela ukufudumeza.
Ukulawulwa kwe-oyile: Ukulawula ukuhanjiswa kweoli kwindonga ye-cylinder ukunciphisa ukukhuhlana ngelixa ukhusela i-oyile eninzi ukuba ingangeni kwigumbi lokutshisa.
Kutheni iiPistons zinemisesane emithathu?
Uninzi lwee-injini zisebenzisa iiringi zepiston ezintathu, nganye ilungiselelwe umsebenzi othile:
Umsesane woKucinezela oPhezulu: Ukumelana noxinzelelo oluphezulu kunye nobushushu, ukutywina iigesi ezivuthayo ukunyusa ukusebenza kakuhle kwe-injini.
I-Second Compression Ring: Ixhasa indandatho ephezulu ekutywineni iigesi kwaye incedisa ukuchithwa kobushushu.
I-Oil Control Ring (I-Scraper Ring): Ikhupha ioli engaphezulu kwindonga ye-cylinder kwaye ibuyisela ioli kwi-crankcase, ukunciphisa ukusetyenziswa kunye nokukhutshwa.
Kwenzeka ntoni xa iiringi zePiston zisilela?
Iimpawu eziqhelekileyo zokungaphumeleli:
Ukulahleka kwamandla e-injini: Ukunyanzeliswa okuvuzayo kunciphisa ukusebenza kakuhle kokutsha.
Ukusetyenziswa kwe-oyile ngokugqithisileyo: Iringi ezigugileyo zivumela i-oyile ukuba ingene kwigumbi lokutsha.
Umsi oluhlaza oluhlaza: Ioyile evuthayo ivelisa i-tint eluhlaza okwesibhakabhaka kwiigesi zokukhupha.
Ukukhutshwa okunyukileyo: Iiringi ezingasebenziyo zinegalelo ekukhutshweni okuphezulu kwe-hydrocarbon.
Injini yokungasebenzi kakuhle: Uxinzelelo olungalinganiyo luphazamisa umjikelo wokutsha.
Iziphumo Zexesha Elide: Ukungahoyi iiringi zepiston ezigugileyo kunokukhokelela kumonakalo osisigxina wodonga lwesilinda, ukungaphumeleli kwe-catalytic converter ngenxa yokungcoliswa kwe-oyile, kunye nokulungiswa kwe-injini ebiza kakhulu okanye ukutshintshwa.
