Yazi yonke into ngepiston yemoto kanye nezingxenye ezakhayo.
I-piston kufanele iklanyelwe ukuvumela ukukhishwa okuhle kokushisa ukugwema ukucindezeleka kwamangqamuzana okubangelwa izinga lokushisa eliphezulu. I-elementi ngayinye eyakha ukwakheka kwayo ibalulekile ekusebenzeni kwenjini.
Injini yemoto yenziwe ngezinto ezimbalwa ezihlanganisa ukwenza imoto ihambe. Ngaphakathi kwalezi zingxenye kunepiston, okuyingxenye yensimbi ebaluleke kakhulu ekusebenzeni kwanoma iyiphi injini. ukuvutha kwangaphakathi.
- Umsebenzi wePiston
Umsebenzi oyinhloko wepiston ukusebenza njengodonga olunyakazayo lwegumbi elivuthayo., esiza ukudlulisa amandla amagesi e-flue ku-crankshaft ngenxa yokunye ukunyakaza ngaphakathi kwesilinda.
Ukunyakaza kwepiston kukopishwa esithendeni senduku yokuxhuma, kodwa iguqulwa eduze kwenduku yokuxhuma kuze kube yilapho ikhanda layo lifika kujenali ye-crankshaft, lapho amandla athi asetshenziselwa ukushayela i-crankshaft.
Ama-piston amaningi enziwa ngokuyinhloko nge-aluminium, evame ukuhlanganiswa ne-magnesium, i-silicon, noma ezinye izakhi ezitholakala kumasilinda enjini. vimba.
– Izingxenye ezakha ipiston
Nakuba i-piston ibonakala iyisiqephu esisodwa, yakhiwe ezinye izakhi, kanje:
- Amazulu. Le elementi itholakala phezulu kwekhanda lepiston futhi ingaba nesimo esihlukile: isicaba, i-concave noma i-convex.
- Ikhanda. Lena phezulu kwepiston ethintana nazo zonke izigaba zoketshezi.
- Izindlu zomnikazi wendandatho. Lezi zakhi zenzelwe ukuthwala izindandatho futhi zihlanganisa izimbobo okudlula kuzo uwoyela wokugcoba.
- iphinikhodi ye-piston. Le ngxenye iqukethe iphinikhodi ye-tubular.
– Izindonga phakathi kwezibambisendandatho: lezi zakhi zihlukanisa iziteshi ezimbili zonyaka ukusuka kwenye.
- Izindandatho. Lezi zakhi zikhonza ukudlulisa ukushisa nokulawula ukugcotshwa kwezindonga ze-cylinder.
