N'ozuzu, engine nwere ihe ngosi nke oriri mmanụ, na oriri nke mmanụ engine dị iche iche n'ime oge ụfọdụ abụghị otu, ma ọ bụrụhaala na ọ na-agafeghị oke uru, ọ bụ ihe nkịtị.
Mmanụ a na-akpọ "ọkụ" pụtara na mmanụ na-abanye n'ime ụlọ ọkụ nke injin ahụ wee soro na combustion na ngwakọta, na-ebute ihe na-eme ka ọ bụrụ oke mmanụ. Ya mere, gịnị mere injin ahụ ji ọkụ mmanụ? Kedu ihe kpatara oke oriri mmanụ?
Mpụpụ mmanụ mpụga
Enwere ọtụtụ ihe na-akpata mgbapu mmanụ, gụnyere: ahịrị mmanụ, drains mmanụ, mmanụ pan gaskets, valvụ mkpuchi gaskets, mmanụ mgbapụta mmanụ, gaskets mgbapụta mmanụ, oge mkpuchi mkpuchi oge na akara camshaft.

N'ihu na azụ mmanụ akara ọdịda
Akara mmanụ n'ihu na azụ mebiri emebi ga-eduga n'ezie na mgbapu mmanụ. Enwere ike ịchọpụta ọnọdụ a naanị mgbe injin na-arụ ọrụ n'okpuru ibu. A ghaghị dochie akara mkpuchi mmanụ bụ isi mgbe ọ gachara, n'ihi na dị ka ntanye mmanụ, ọ ga-eme ka mmiri dị elu.
Isi iyi ma ọ bụ ọdịda
Ihe mkpuchi isi nke eyighị ma ọ bụ nke na-adịghị mma nwere ike ịkụnye oke mmanụ ma tụba ya na mgbidi cylinder. Ka ike na-ebu ibu na-abawanye, a na-atụba mmanụ karịa. Dịka ọmụmaatụ, ọ bụrụ na nkwụsị nhazi nke 0.04 mm na-enye mmanu na oyi nkịtị, ọnụ ọgụgụ mmanụ a na-atụfu bụ ihe nkịtị ma ọ bụrụ na enwere ike idowe ihe nkwụsị.
