Abstract

A propulsion system useful, for example, for automobiles, comprising an air compressor, a rotary engine, and a multiple stage turbine mounted upon a common shaft, and an infuser section comprising a plurality of nozzles for injecting air into the exhaust gases from the turbine to reduce the temperature and consequently the pressure of the exhaust gases prior to passage into an exhaust pipe.

Claims

1. An apparatus comprising:

an outer housing;

an inner housing disposed in said outer housing;

a turbine disposed in said inner housing;

a chamber disposed in said outer housing downstream of said inner housing and in fluid communication with said turbine;

discharge means mounted downstream of said chamber for discharging gases therefrom;

said outer housing having a wall portion spaced from said inner housing and said chamber to define an air duct, said air duct being in fluid communication with said chamber;

means for introducing high pressure gases into said turbine;

whereupon the gases pass through said turbine into and through said discharge means;

a plurality of elongated tubular nozzles being directed into said chamber to establish said fluid communication with said air duct, said nozzles comprising at least a first set of relatively short tubular nozzles projecting into said chamber and a second set of relatively longer tubular nozzles projecting into said chamber, said longer nozzles being disposed downstream from said shorter nozzles, said nozzles having inlets which lie in fluidic flow cooperation with said air duct and outlets which direct the incoming air toward said discharge means, said inlets being flush with the wall of said chamber and said outlets being disposed predetermined varying distances within said chamber;

means for introducing air into said air duct whereupon at least a portion of the air enters said chamber through said nozzles, said air mixing with the gases discharged into said chamber from said turbine and discharging through said discharge means admixture therewith.

2. Apparatus according to claim 1, further comprising additional turbine means provided at said discharge means, a shaft for said turbine and said additional turbine means extending through said discharge means, and at least some of said nozzles being positioned to direct air and gases toward said additional turbine means.

3. Apparatus according to claim 2, further comprising means to supply additional air from said duct into said discharge means downstream of said additional turbine means.
