Abstract
A multi-cylinder internal combustion engine comprising a cylinder assembly with intake ports and exhaust ports arranged in register, wherein the distribution system for opening and closing said intake and exhaust ports include two rotary pipes each consisting of a plurality of mutually communicating aligned hollow valves. The rotary intake pipe and the rotary exhaust pipe are housed in an intake manifold and an exhaust manifold respectively, each defining a chamber surrounding said intake pipe and said exhaust pipe respectively over a large part of the periphery thereof, said chambers being sealed off from one another and arranged so that gaseous fluids can flow freely outside and along said rotary distribution pipes.
Claims12
A multi-cylinder internal combustion engine comprising at least one set of cylinders (1) whose combustion chambers (3) are each provided with an intake port (4) and an exhaust port (5), which intake ports (4) and exhaust ports (5) of said set of cylinders (1) are disposed in alignment, the distribution means which allow for the opening and closure of said intake ports (4) and exhaust ports (5) comprising two rotary pipes (T-8, T-9) of circular cross-section, each of which is formed by a plurality of hollow valves (Sa, 8b) aligned end to end and in communication with one another, so as to allow the free circulation of the gaseous fluids inside and from one end to the other of the rotary pipes (T-8, T-9) whose lateral wall is provided with a plurality of apertures (10a, 10b, 10c, 10d;
- 11a, 11b, 11c, 11d), the number of which corresponds to the number of cylinders to be served or supplied, one (T-8) of which rotary pipes allows the opening and closure of the aligned intake ports (4) of the set of cylinders (1), while the second (T-9) allows the opening and closure of the aligned exhaust ports (5) of said set of cylinders, characterized in that the rotary intake pipe (T-8) and the rotary exhaust pipe (T-9) are housed in an intake manifold (31) and an exhaust manifold (32), respectively, each of which delimits a space or chamber which surrounds said intake pipe (T-8) and said exhaust pipe (T-9), respectively, which chambers (31, 32) are impermeably separated and disposed so as to allow the free circulation of gaseous fluids outside and along said rotary distribution pipes (T-8, T-9), from one end to the other of said intake manifold (31) and exhaust manifold (32).
