ABSTRACT:
Connecting exhaust ducts of gradually widening cross section lead from the exhaust ports of a particular cylinder to a common manifold, being continued inside the manifold for a length greater than half of the diameter of the manifold and leaving an outflow cross section between the end of the connecting duct and the facing wall of the manifold equal to or slightly greater than the exit cross section of the connecting duct. Between junctions with the connecting ducts the manifold has sections of constricted cross section, providing baffling between the connecting ducts. The arrangement enables the kinetic energy of the outflow of exhaust gas to be more effectively utilized for sucking in the scavenging air.
