1. Nwụnye mgbanaka piston:

Enwere ike itinye mgbanaka piston tozuru oke na piston mgbe nyochachara ya. Lezienụ anya na oghere oghere na ntụziaka nke mgbanaka n'oge echichi. Na mkpokọta, enwere akụ elu ma ọ bụ akara TOP n'akụkụ mgbanaka piston. A ga-etinyerịrị ihu a elu. Ọ bụrụ na a gbanwee ya, ọ ga-eme ka mmanụ ọkụ dị oke ọkụ; hụ na oghere oghere nke mgbanaka na-esi na ibe ya (n'ozuzu 180 Celsius site na ibe ya) na-ekesa nke ọma, n'otu oge ahụ, hụ na oghere adịghị adaba na ọnọdụ nke oghere piston; A na-eji ngwá ọrụ pụrụ iche eme ihe mgbe ị na-etinye na piston, na ntinye akwụkwọ ntuziaka adịghị atụ aro; ṅaa ntị na ntinye site na ala ruo n'elu, ya bụ, wụnye mgbanaka mmanụ mbụ, wee wụnye mgbanaka ikuku nke abụọ, mgbanaka gas, ṅaa ntị ka ị ghara ikwe ka mgbanaka piston kpoo mkpuchi nke piston n'oge ntinye.

2. A na-etinye mgbakọ mkpanaka piston na engine:

Hichaa nke ọma liner cylinder tupu echichi, ma tinye obere oyi akwa nke mmanụ engine na mgbidi cylinder. Tinye ụfọdụ mmanụ injin na piston nke ejiri mgbanaka piston arụnyere yana mkpanaka na-ebu ohia, wee jiri ngwá ọrụ pụrụ iche pịnye mgbanaka piston ma wụnye mgbakọ piston njikọ n'ime engine. Mgbe echichi gasịrị, mee ka mkpanaka njikọ ahụ sie ike dịka usoro torque na usoro siri ike siri dị, wee tụgharịa crankshaft. A na-achọrọ crankshaft ka ọ gbanwee n'efu, na-enweghị nkwụsịtụ doro anya, na nguzogide ntụgharị agaghị adị oke ibu.
