PROCEDURE TO IMPROVE THE OPERATION OF A SUPERCHARGED THERMAL MOTOR AND AIR SWEEP, AND THERMAL MOTOR PREPARED FOR THE EXECUTION OF SUCH PROCEDURE.

摘要

THE PROCEDURE CONSISTS OF REGULATING, ABOVE A SAME EXHAUST GAS COLLECTOR (8,10), A NUMBER OF CYLINDERS (2,3; 1,4) SUCH AS THE PRESSURE IN THE EXHAUST PIPE (12, ... 42) IT PRESENTS, ACCORDING TO TIME, SENSITIVE AMPLITUDE FLUCTUATIONS, AND IN OPENING THE EXHAUST VALVE (6) OF THE CYLINDER (1) THAT IT IS SUCTIONING OR FILLING (THAT IS, NEAR THE LOW DEAD POINT) SO THAT FOR A REGIME ZONE, A PHASE (28) OF LOW INSTANT EXHAUST PRESSURE PRESENT IN THE EXHAUST PIPE ALLOWS TO ASSURE AN EXHAUST PIPE SWEEP (1A) / CYLINDER / (1) / EXHAUST PIPE (1E) DURING THE SIMULTANEOUS OPENING OF THE VALVE (5) AND THE EXHAUST VALVE (6). PHASE (29) OF STRONG INSTANT EXHAUST PRESSURE, DUE TO ANOTHER CYLINDER, AFTER THE INLET VALVE CLOSES (5) AND WHILE THE EXHAUST VALVE (6) IS KEPT OPEN, IT IS USED TO PERFORM A CYLINDER POST-FILLING (1) WITH AIR (A) PREVIOUSLY STORED IN THE EXHAUST PIPE (1), THE DIMENSION OF THE TURBINE (T) IS CHOSEN SO THAT AT REGIMES GREATER THAN SUCH CERTAIN AREA, IT IS NOT PRACTICALLY POST-FILLED WITH THE CYLINDER (1) ESCAPE.
