The cylinder gasket dị n'etiti isi cylinder na ngọngọ cylinder, ọrụ ya bụ imeju micro pores n'etiti ngọngọ cylinder na isi cylinder, na-eme ka akara dị mma n'elu njikọ ahụ, si otú a na-eme ka akara nke ụlọ combustion na igbochi nkwụsị nke cylinder. na akwa jaket mmiri.
Otu piston na-ejikọta mkpanaka bụ ihe na-ebugharị nke engine, nke na-ebufe nrụgide nke gas combustion na crankshaft, na-eme ka ọ gbanwee na mmepụta ike. Otu mkpara njikọ piston bụ nke nwere piston, mgbanaka piston, pin piston na mkpanaka njikọ.
Isi ọrụ nke piston bụ iguzogide nrụgide nke gas combustion ma bufee ike a na njikọ njikọ site na piston pin iji mee ka crankshaft gbanwee. Na mgbakwunye, elu nke piston, isi cylinder, na mgbidi cylinder ọnụ na-etolite ọnụ ụlọ ọkụ.
