Enwere mmiri na nzacha ikuku. Enwere mmiri na injin?
Ọ bụrụ na idei mmiri rikpuola nzacha ikuku, anwala ịmalite mmalite nke abụọ. N'ihi na ụgbọ ala wading, mmiri ga-agafe na engine oriri, nke mbụ n'ime ikuku nyo mmewere, mgbe ụfọdụ na-eduga na engine ụlọ ahịa. Ma ọtụtụ n'ime mmiri kemgbe site ikuku nyo mmewere, n'ime engine, malite ọzọ ga ozugbo na-eduga engine mebiri, kwesịrị ịbụ oge mbụ ịkpọtụrụ mmezi nzukọ maka ọgwụgwọ.
Ọ bụrụ na engine ahụ kwụsịrị, nọgide na-amalite oge nke abụọ, mmiri ga-abanye ozugbo n'ime cylinder site na ntinye ikuku, gas nwere ike ịgbakọ ma mmiri enweghị ike ịgbakọ. Ya mere, mgbe crankshaft na-akwagharị mkpanaka njikọ na ntụziaka nke mkpakọ piston, mmiri enweghị ike ịgbakọ, nnukwu mmeghachi omume ike ga-eduga na-ehulata nke njikọ njikọ ahụ, ọdịiche dị na ike nke njikọ njikọ ahụ, ụfọdụ ga-eji nlezianya mee ihe. hụ na ọ gbafuwo. Ụdị ụfọdụ nwere ike inwe ntakịrị nrụrụ, ọ bụ ezie na mgbe mmiri gwụchara, ha nwere ike ịmalite nke ọma na engine na-arụ ọrụ nke ọma. Ma mgbe ịkwọ ụgbọala ruo oge ụfọdụ, nrụrụ ahụ ga-abawanye. Enwere mkpọda siri ike nke mkpanaka njikọ, na-ebute ihe ize ndụ nke nkwụsị nke ngọngọ cylinder.
