Abstract

Invenţia se referă la domeniul construcţiei motoarelor şi poate fi utilizată în mecanismele bielă-manivelă ale motoarelor cu ardere internă (MAI).Biela cu lungime variabilă a MAI conţine capul bielei (2) şi al pistonului (1), conexate prin tijă (3) cu pistonul (5) amplasat în hidrocilindru (4), formând cavităţi (12,13) cu volum variabil, care comunică între ele şi sunt umplute cu lichid, capul bielei (2) fiind utilat cu o proeminenţă, în care este executat hidrocilindrul (4), în pereţii căruia sunt prevăzute canale de admisiune (10,11) şi de evacuare (7,8), care unesc ambele cavităţi ale lui cu volum variabil cu spaţiul carterului motorului, iar între capetele bielei pe tijă (3) este instalat un arc conic telescopic (15) de comprimare a rigidităţii variabile.Rezultatul tehnic constă în aceea că invenţia asigură menţinerea presiunii constante în camera de ardere, adică corpul de lucru arde, de preferinţă, la presiune constantă.MAI cu aşa ciclu de funcţionare este ecologic mai pur, deoarece se exclude necesitatea adaosurilor de antidetonaţie, iar consumul de combustibil se reduce de 2-5 ori.
