Abstract
A multiple turbosupercharger system for an internal combustion engine routes the air from ambient, or combustible gas mixture from downstream of the carburetor, serially through a low-pressure compressor, a high-pressure compressor, the engine's intake and exhaust manifolds, and thence through the high-pressure and low-pressure turbines, thereafter exhausting to ambient. The high-pressure turbine, being of the meridionally divided wall type, is coupled to the engine's exhaust manifold so as to efficiently utilize the blow-down pulse energy of the exhaust gas. The low-pressure turbine has a movable vane in its gas distributor for establishing exhaust gas flow rate control without substantial loss of total energy of the fluid. The vane is positioned by an actuator under the control of sensing means which senses a suitable system or engine parameters.
