Live-gas conduit system for turbocharged six-cylinder engines

Claim 1

A multi-space live-gas conduit system for six-cylinder, serially arranged internal-combustion piston engines, said cylinders having suction inlets, and including a turbocharger associated with said cylinders; the system being linked between said suction inlets and said tubrocharger, and comprising: two separate resonance tanks, each attached to said suction inlets of three adjoining cylinders, said tanks having a volume larger than half of the stroke volume of said three cylinders but smaller than the tenfold thereof; a resonance tube for each tank, adjoining outlet openings of the latter, and having lengths of their center lines which are at least eight times that of the diameter of a circle having the cross-section of said tubes; and a damping tank that links inlet openings of said tubes with the pressure side of said turbocharger; said tubes respectively interconnecting said resonance tanks with said damping tank; said tanks and said tubes being all successively disposed along the longitudinal axis of the engine; wherein the characteristic longitudinal extensions of said tanks and of said tubes all have the same direction; and further comprising a connection from each resonance tube that opens into one of said resonance tanks that is farther away from the respective inlet opening of said tube.
