MOTOR comprising at least two paired cylinders (2 and 3) differentiated by their displacement and two lines of crankshafts (4 and 5), COUPLED EQUALS ONE ROTATION SPEED GEAR (19, 20,21) and rail A three-axis timing transmission concentric (17, 28, 32) removable from the motor unit (18) and whose function is to decrease the ratio VOLUMETRICA IN INCREASING PRESSURE INTAKE. RELATIONS VOLUMETRIC maximum and minimum normalize LIMITS offset ANGLE BETWEEN the two crankshafts (4 and 5) by volume ratios between the two paired cylinders (2 and 3) and between these two cylinders (2 and 3) AND CLEARANCE , SO ONE PART, THE START OF JOURNEY OF TRANSMISSION TIMED VARIABLE PERFORMS IN PHASE END OF cOMPRESSION, ONE OF FORWARD PISTON (8) GRADE UNIT derating ANGLE increase between the two crankshafts (4 and 5 ) AND MOREOVER, THE END OF TRAVEL ASSOCIATES LAEXPANSION transmission TIMED GAS ON COMBUSTION PISTON (8) AT LEAST FROM INSTANT ON TORQUE cRANK short-stroke crankshaft (5).
