Abstract

Invenţia se referă la construcţia de maşini, în particular la motoarele cu ardere internă.Motorul cu ardere internă conţine primul şi al doilea cilindri (12, 14). Volumul util al primului cilindru (12) depăşeşte volumul util al cilindrului al doilea (14), totodată cilindrul al doilea este executat în capul primului cilindru. Pistoanele, primul şi al doilea (16, 18), sunt instalate cu posibilitatea mişcării rectilinii-alternative, respectiv, în primul şi al doilea cilindri (12, 14), pistonul al doilea (18) fiind executat în formă de proeminenţă pe fundul primului piston (16). În pistonul al doilea (18) este executată o cameră de ardere (20) având un orificiu (44) pentru aer care comunică cu primul cilindru (12) şi cel de-al doilea orificiu (40) care comunică cu al doilea cilindru (14). Motorul este dotat cu primul mijloc de admisie (25) pentru alimentarea cu aer a primului cilindru (12) în timpul cursei de admisiune a primului piston (16), la fel şi un mijloc de admisie (36) pentru alimentarea cu combustibil a cilindrului al doilea (14). Între primul şi al doilea cilindri există o trecere, care asigură posibilitatea deplasării aerului din primul cilindru (12) în cilindrul al doilea (14), evitând camera de ardere (20), pe parcursul unghiului predeterminat de deplasare al pistoanelor în raport cu cilindrii, contribuind la deplasarea gazelor din cilindrul al doilea (14) în camera de ardere (20).Este prevăzut, de asemenea, un mijloc suplimentar pentru reglarea deplasării aerului.
