1: zvepiston zvinhuuye tekinoroji yaienderana nemhando dzakasiyana dzeinjini, mamiriro ekushandisa, uye kufunga kwemitengo.
Piston zvinhu zvinosanganisira: Cast aluminium, Forged aluminium, Simbi uye Ceramic.
Cast aluminium ndiyo inonyanya kushandiswa mupiston. Iyo yakareruka, isingadhuri, uye inopa yakanaka yekupisa conductivity. Nekudaro, haina kusimba sezvimwe zvinhu uye inogona kukanganisa pasi pekunetseka kwakanyanya kana kupisa kwakanyanya.
Forged aluminium zvinhu yakasimba kupfuura cast aluminium uye inogona kubata yakanyanya kushushikana uye tembiricha mitoro. Inowanzoshandiswa mune yakakwirira-inoshanda injini.
Simbi pistons yakasimba kwazvo uye yakasimba, uye inogona kubata yakanyanya kushushikana uye tembiricha mitoro. Iwo anowanzo shandiswa muinjini dzedhiziri uye zvimwe zvinorema-basa zvikumbiro senge marori anorema, marori anorema ari kuita chinhu chakakosha chekufambisa chishandiso muhupenyu hwedu, vese mushandisi vanongwarira nezvazvo.
Ceramic pistons yakanyanya kureruka uye inopa yakanakisa kupisa kwemafuta. Iwo anowanzo shandiswa muinjini dzepamusoro-inoshanda uye mijaho yekushandisa, sezvo mutengo unodhura kupfuura vamwe.
Piston tekinoroji yakafambira mberi zvakare mumakore achangopfuura, nekuvandudzwa kwemachira uye mamwe marapirwo anogona kuvandudza mashandiro uye kusimba. Mimwe mienzaniso inosanganisira:
1. Kuomesa anodizing: Kuita uku kunosanganisira kupfekedza piston nearuminiyamu oxide yakaoma, isingapfeki. Izvi zvinogona kuvandudza kusimba uye kuderedza friction.
2. Friction-kuderedza machira: Aya machira akagadzirirwa kuderedza kupokana pakati pepiston uye cylinder madziro. Izvi zvinogona kuvandudza kushanda uye kuderedza kupfeka.
3. Thermal barrier coatings: Aya machira anoshandiswa kune korona yepiston kuti avandudze kupisa kwekupisa uye kuderedza kushushikana kwekushisa. Izvi zvinogona kuvandudza mashandiro uye kuderedza njodzi yekutadza kwepiston.
Mapistoni mazhinji zvino akagadzirwa aine huremu hwekudzikisira mundangariro, achishandisa zvigadzirwa zvepamberi uye matekiniki ekugadzira kudzikisa huwandu uku uchichengetedza simba uye kusimba. Izvi zvinogona kuvandudza kushanda uye kushanda kwemafuta.
