(1) Igwe na-akụ ụda nke mgbanaka piston.
Mgbe injin ahụ na-arụ ọrụ ogologo oge, a na-eyi mgbidi cylinder ahụ, ma ebe akụkụ elu nke mgbidi cylinder adịghị ejikọta ya na mgbanaka piston fọrọ nke nta ka ọ bụrụ na ọ na-edobe geometry mbụ na nha, nke na-eme ka mgbidi cylinder mepụta nzọụkwụ. . Ọ bụrụ na ochie cylinder isi gasket ma ọ bụ ọhụrụ cylinder isi gasket dochie dị oke mkpa, na-arụ ọrụ piston mgbanaka ga-adaba na cylinder mgbidi nzọụkwụ, na-eme ka a dull "pop" metal bump. Ọ bụrụ na ọsọ engine na-abawanye, mkpọtụ na-adịghị mma ga-abawanye. Na mgbakwunye, ọ bụrụ na mgbanaka piston agbajiri ma ọ bụ ọdịiche dị n'etiti mgbanaka piston na mgbanaka ahụ dị oke ibu, ọ ga-emekwa ka ụda ịkụ aka buru ibu.

(2) Ụda ntapu ikuku nke mgbanaka piston.
Ike na-agbanwe nke mgbanaka piston na-ebelata, oghere oghere dị oke ibu ma ọ bụ oghere na-ekpuchi ya, na mgbidi cylinder nwere oghere, wdg, nke ga-eme ka mgbanaka piston na-agbapụta. Ụda ahụ bụ ụda "ịṅụ mmanya" ma ọ bụ "ịkpọ ụda" ma ọ bụ ụda "popping" mgbe enwere ikuku siri ike. Usoro nchoputa bụ gbanyụọ engine mgbe mmiri okpomọkụ nke engine ruru n'elu 80 ℃. N'oge a, ị nwere ike ịgbanye ntakịrị mmanụ dị ọcha na cylinder ahụ, gbanye crankshaft maka ntụgharị ole na ole, wee malitegharịa engine ahụ. Ọ bụrụ na ọ pụtara, enwere ike ikwubi na mgbanaka piston na-agbapụta. Ntị: Nyocha ụgbọ ala na nlekọta isi

(3) Mkpọtụ na-adịghị mma n'ihi oke ikuku carbon.
Mgbe enwere oke ikuku carbon, ụda na-adịghị mma na cylinder bụ ụda dị nkọ. Ebe ọ bụ na a na-agbapụta ihe ndị na-etinye carbon n’ọkụ na-acha ọbara ọbara, injin ahụ nwere ihe mgbaàmà nke mgbanye akabeghị aka, ọ dịghịkwa mfe ịgbanyụ ya. Nhazi nke nkwụnye carbon na mgbanaka piston bụ nke kachasị n'ihi enweghị njide siri ike n'etiti mgbanaka piston na mgbidi cylinder, oghere oghere dị ukwuu, ntinye nke mgbanaka piston, na nchikota nke ọdụ ụgbọ mmiri, wdg. Akụkụ mgbanaka ahụ na-ere ọkụ, na-eme ka e guzobe ihe nkwụnye carbon ma ọ bụ ọbụna na-arapara na mgbanaka piston, na-eme ka mgbanaka piston na-efunahụ ike ya na akara akara. Na mkpokọta, enwere ike iwepụ mmejọ a mgbe ejiri nkọwa dabara adaba dochie mgbanaka piston.
