Abstract: An exhaust system for an internal combustion engine including an elongated tube for receiving exhaust gas and exhaust flow modification structure within the tube interior configured to cooperate with the elongated tube to produce a laminar flow of exhaust gas and modify the flow speed of the exhaust gas due to the venturi effect. The exhaust system includes two spaced structural components which form restricted a annular flow path to enhance the venturi effect.

Abstract: Apparatus for testing and evaluating the performance of an automobile under simulated conditions includes torque applicators for connection to wheel shafts of an automobile and for applying torque forces to the wheel shafts, movable supports supporting the torque applicators and a force applicator for connection to the automobile to apply forces to the automobile. A control associated with the torque applicators and the force applicator varies the torque forces applied by the torque applicators to the wheel shafts and varies the forces applied to the automobile by the force applicator.

Abstract: A sensor is employed in conjunction with an internal combustion engine having at least one hydrocarbon fuel combustion chamber and an air inlet for introducing air into the combustion chamber to sense termination of operation of the internal combustion engine. The sensor closes a valve leading to a carburetor inlet of the engine when termination of operation of the internal combustion engine is sensed. The valve and associated structure improve the performance of the internal combustion engine when the valve is in open position by enhancing fluid flow through the air inlet leading to the carburetor during operation of the internal combustion engine.
