I. Piston
1, umsebenzi: ukumelana noxinzelelo lwegesi, kwaye ngokusebenzisa iphini yepiston kunye nentonga yokudibanisa ukuqhuba ukujikeleza kwe-crankshaft: umphezulu wepiston kunye nentloko yesilinda, udonga lwesilinda kunye ukwenza igumbi lokutsha.
2. Indawo yokusebenza
Ubushushu obuphezulu, iimeko ezimbi zokusasaza ubushushu; Ubushushu bokusebenza bephezulu bufikelela kwi-600 ~ 700K, kwaye usasazo alufani: isantya esiphezulu, isantya esithe ngqo sifikelela kwi-10m/s, phantsi kwamandla amakhulu okuxinezeleka. Iphezulu lepiston liphantsi koxinzelelo oluphezulu lwe-3 ~ 5MPal (injini yepetroli), nto leyo ebangela ukuba ijike kwaye iphule uqhagamshelo lokulingana.
Umsebenzi we-piston top 0: yinxalenye yegumbi lokutsha, indima ephambili yokumelana noxinzelelo lwegesi. Imilo yephezulu inxulumene nemilo yegumbi lokutsha
Indawo yentloko yepiston (2): Inxalenye ephakathi komngxuma olandelayo weringi kunye nomphezulu wepiston
Umsebenzi:
1. Dlulisa uxinzelelo oluphezulu lwepiston kwinduku yokudibanisa (ukudluliselwa kwamandla). 2. Faka iringi yepiston uze uvale isilinda kunye neringi yepiston ukuthintela umxube ovuthayo ukuba ungangeni kwi-crankcase
3. Dlulisa ubushushu obufunxwe ngentla ukuya eludongeni lwesilinda ngeringi yepiston
Isiketi sepiston
Indawo: Ukusuka kwisiphelo esisezantsi se-oil ring groove ukuya kwinxalenye esezantsi yepiston, kuquka nomngxuma wesihlalo sepini. Kwaye uthwale uxinzelelo olusecaleni. Umsebenzi: ukukhokela intshukumo ejikelezayo yepiston kwisilinda,
