Ọdịdị na ụkpụrụ ọrụ nke piston

Enwere ike kewaa piston niile ụzọ atọ: okpueze piston, isi piston na uwe mwụda piston.

Isi ọrụ nke piston bụ iguzogide nrụgide combustion na cylinder ma nyefee ike a na crankshaft site na piston pin na njikọ njikọ.Na mgbakwunye, piston na-etolite ọnụ ụlọ combustion yana isi cylinder na mgbidi cylinder.

Okpueze piston bụ akụkụ nke ụlọ ọkụ, n'ihi ya, a na-emekarị ya n'ụdị dị iche iche.Kachasịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịpụta elu dị larịị ma ọ bụ n'elu concave iji mee ka ọnụ ụlọ combustion kọmpat na nhazi, obere na mpaghara mkpofu ọkụ, yana dị mfe na usoro nrụpụta.A na-ejikarị piston convex eme ihe n'ime igwe mmanụ ụgbọala nwere strok abụọ.A na-ejikarị olulu dị iche iche eme okpueze piston nke injin dizel.

Isi piston bụ akụkụ dị n'elu oche pin piston.Isi piston na-eji mgbanaka piston iji gbochie okpomọkụ dị elu na ikuku ikuku dị elu ịbanye na crankcase, ma n'otu oge ahụ na-egbochi mmanụ ịbanye n'ime ụlọ ọkụ;Ọtụtụ n'ime okpomọkụ na-etinye n'elu piston na-agafekwa isi piston Akụkụ ahụ na-agafe na cylinder, wee gafee site na usoro jụrụ oyi.

A na-akpọ akụkụ niile dị n'okpuru mgbanaka piston piston skirts.Ọrụ ya bụ ịduzi piston ka ọ na-emegharịghachi na cylinder ma buru nrụgide n'akụkụ.Mgbe injin ahụ na-arụ ọrụ, piston ga-ehulata ma degharịa n'ihi nrụgide gas dị na cylinder.Mgbe piston na-ekpo ọkụ, a na-enwekwu ígwè na piston pin, ya mere mgbasawanye ya dị ukwuu karịa ebe ndị ọzọ.Na mgbakwunye, piston ga-emepụta nrụrụ mgbakasị n'okpuru ọrụ nrụgide akụkụ.N'ihi nrụrụ dị n'elu, akụkụ obe nke uwe mwụda piston na-aghọ ellipse nke nwere isi axis na ntụziaka nke piston pin.Tụkwasị na nke ahụ, n'ihi nkesa na-adịghị mma nke okpomọkụ na oke nke piston n'akụkụ ntụziaka axial, mgbasawanye ọkụ nke akụkụ ọ bụla dị ukwuu na obere.
