Were ụkpụrụ arụ ọrụ nke injin strok anọ na injin strok abụọ dị ka ọmụmaatụ: injin strok anọ na-ejikarị eme ihe.Igwe strok anọ ahụ pụtara na cylinder ahụ na-enwu otu ugboro n'ime mmegharị piston anọ ọ bụla.Ụkpụrụ ọrụ kpọmkwem bụ ndị a:

Nri: N'oge a, valvụ oriri na-emepe, piston na-aga ala, na ngwakọta nke mmanụ ụgbọala na ikuku na-abanye n'ime cylinder.

Mkpakọ: n'oge a, a na-emechi valvụ ntinye na valvụ iyuzucha n'otu oge, piston na-aga n'elu, na ngwakọta na-ejikọta.

Mkpọ ọkụ: mgbe a na-ejikọta igwekota na opekempe, plọg ọkụ ahụ ga-awụlikwa elu ma gbanye gas agwakọtara, na nrụgide sitere na combustion ga-akwada piston ahụ ma mee ka crankshaft gbanwee.

Ngwunye: Mgbe piston na-agbada n'ebe kachasị ala, valvụ ikuku na-emepe emepe, a na-ewepụkwa ikuku gas.Piston na-aga n'ihu na-arịgo iji wepụta oke ikuku gas.

Ụkpụrụ na-arụ ọrụ nke engine strok abụọ bụ na piston na-ebuli elu na ala maka strok abụọ na ọkụ ọkụ na-agbanye otu ugboro.Usoro oriri nke engine strok nke abụọ dị nnọọ iche na nke engine stroke nke anọ.Ekwesịrị ịpịkọta engine nke nwere strok ugboro abụọ.N'elu injin strok nke abụọ, ngwakọta na-abanye na crankcase mbụ wee banye na cylinder.Kpọmkwem, ọ na-asọba n'ime ụlọ combustion, ebe ngwakọta nke engine strok nke anọ na-abanye ozugbo na cylinder.A na-eji crankcase nke engine strok nke anọ na-echekwa mmanụ, Ebe ọ bụ na a na-eji crankcase nke engine abụọ strok na-echekwa gas agwakọtara na enweghị ike ịchekwa mmanụ, mmanụ a na-eji maka engine strok abụọ abụghị mmanụ combustion a na-emegharịghachi.

Usoro ọrụ nke engine strok nke abụọ bụ nke a:

Piston na-ebuli elu na ikuku agwakọtara na-abanye na crankcase.

Piston na-agbadata iji nyefee ikuku agwakọta na ụlọ ọkụ, na-emecha mkpakọ mbụ.

Mgbe ngwakọta ahụ rutere cylinder, piston na-arịgo elu ma mechie ntinye na ntinye.Mgbe piston na-agbanye gas na oke opekempe (nke a bụ mkpakọ nke abụọ), plọg ọkụ na-enwu.

Nrụgide ọkụ na-eme ka piston gbadaa.Mgbe piston ahụ na-agbada n'otu ọnọdụ, a na-ebu ụzọ mepee ọdụ ụgbọ mmiri ahụ, a na-ahapụkwa ikuku ikuku wee mepee oghere ikuku.Gas agwakọtara ọhụrụ na-abanye n'ime cylinder iji wepụ gas nke fọdụrụnụ.
