Abstract (en)
[origin: EP0507648A1] Two-stroke engine including a cylinder in which a piston moves, a means (6, 8; 21) allowing a pressurised charge to be admitted into the cylinder, and at least two admission slots (2, 4; 20) in the wall of the cylinder. According to the invention, the motor furthermore includes a means (5, 7; 30; 60) intended selectively to block the passage section of the slots for admission of the charge, as a function of at least one parameter of the running of the motor. <??>the selective blocking means may consist, for example, of a rotary valve (30) placed facing the admission slot(s) (20) and including at least two transverse openings (32). <IMAGE>
