N'ikwu okwu banyere pistons ụgbọ ala, mgbe ahụ, anyị ga-ekwu maka ihe ngosi nke ịkụ ọkpọ. Nke a bụ otu n'ime ọdịda ụgbọ ala a na-ahụkarị. Ị maara otú e si edozi ọdịda ndị dị otú ahụ?
Tupu anyị edozi nsogbu ịkụ ọkpọ piston, anyị ga-ebu ụzọ ghọta ihe na-ebute ihe a.

◆Ọdịiche dị n'etiti piston na mgbidi cylinder buru ibu.

Mgbe ọ na-agba ọsọ ruo oge ụfọdụ, a ga-eyi uwe mwụda piston na cylinder nke ukwuu, na-eme ka ọ pụta ìhè ma na-akụ cylinder ahụ.

◆A na-emebi mkpanaka njikọ nke onye ọ bụla n'ihi ihe dị iche iche, na-eme ka piston na-agwụ ike, ọdịiche ahụ na-ebuwanye ibu ma kụọ cylinder ahụ. Piston ịkụ aka ga-eme ka injin mmanụ karịrị akarị, ntapu mmanụ mmanụ, oke mmanụ na-eri, yana akụ na ụba dara ogbenye. Mgbe piston ahụ kụrụ cylinder ahụ nke ọma, piston ga-agbaji ma mebie cylinder ahụ. N'ihi ya, mkpanaka njikọ ga-agbaji na ngọngọ cylinder ga-emebi.

Mgbe injin ahụ na-agba ọsọ ruo oge ụfọdụ, piston cylinder na-agwụ ike. Na mgbakwunye na mmanye mmanye na-adịghị mma, ọdịiche dị n'etiti piston na cylinder na-abawanye n'ihi uwe, na nzọụkwụ dị njọ na-apụta ntakịrị n'okpuru mgbanaka gas mbụ, na-eme ka piston kụọ cylinder ahụ. Mee mkpọtụ iju.

Ọ dị mma iji dozie nsogbu ahụ ma ọ bụrụ na ị ghọtara ihe kpatara ya:

◆Ọ bụrụ na enwere ụda ịkụ aka doro anya mgbe engine okpomọkụ bụ ihe nkịtị, gbalịa ka ịzere ọrụ ọsọ ọsọ ma gbasaa ma mezie ya ozugbo enwere ike.

Mgbe o wepụsịrị isi cylinder ahụ wee dọpụta piston ahụ, a na-achọpụta na cylinder ahụ dị oke gburugburu, na-agbaji, ma ọ bụ ọdịiche dị n'etiti piston na cylinder buru ibu. Dochie eriri cylinder, piston na mgbanaka piston.

◆Ọ bụrụ na achọpụtara eriri njikọ ahụ na-emezigharị, ọ ga-edochi ya dịka o kwere mee.

Mgbe a malitechara engine ahụ, a na-enwe ụda ịkụ aka mgbe ọ na-arụ ọrụ obere okpomọkụ. Mgbe okpomọkụ dị mma, ụda na-apụ n'anya, yabụ ị nwere ike ịhapụ ya naanị ya.
