Abstract

U okviru rada, prikazana su različita rješenja izvedbe modularnog klipa motora s unutarnjim
izgaranjem koja omogućuju promjenu kompresijskog omjera. Promjena kompresijskog omjera
postignuta je oblikovanjem prostora izgaranja u čelu klipa, prema Ottovom načinu izgaranja, i
promjenom kompresijske visine, što je rezultiralo variranjem kompresijskog volumena.
Predloženo je nekoliko koncepata koji bi se mogli primijeniti na klipu motora Hatz 1D81. Zatim
su postavljeni kriteriji za evaluaciju predloženih koncepata te je na temelju tih kriterija
odabrano najprikladnije rješenje. Odabrani koncept izveden je višestrukim vijčanim spojem s
gornje strane klipa. Provedena je detaljna razrada odabranog koncepta i priložena tehnička
dokumentacija.

Abstract (english)

In the framework of the paper, various solutions for the performance of the modular piston of the internal combustion engine, which would allow changing the compression ratio, are presented. The change in compression ratio was achieved by shaping the combustion space in the front of the piston, according to Otto's combustion method, and by changing the compression height, which resulted in varying the compression volume. Several concepts have been suggested that could be applied to the Hatz 1D81 engine piston. Then, criteria were set for evaluating the proposed concepts, and based on these criteria, the most appropriate solution was selected. The chosen concept is made with a multiple screw connection on the upper side of the piston. A detailed elaboration of the selected concept was carried out and technical documentation attached.
