ABSTRACT:
A staged induction engine with an air duct therethrough open at both ends, and defining a plurality of venturis therein axially spaced from each other where each of the venturis has a throat of a diameter smaller than the throat of the next upstream of venturis, a burner unit defining combustion chamber therein, exhaust jet pumping means operatively associated with the exhaust gases from the burner unit and including a plurality of venturi jet pumping tubes corresponding in number to the venturis with each of said venturi jet pumping tubes defining an exhaust passage therethrough in communication with the exhaust gases from the combustion chamber with a downstream exhaust outlet from which the exhaust gases are discharged where one of the exhaust outlets is positioned upstream of the throat of each of the venturis so that the exhaust gases will be discharged through the throat of the venturi associated therewith to force in the air passage through the air duct upstream of the venturi through the venturi under jet pumping action, and means for supplying a combustible air/fuel mixture to the burner unit to operate same.
