Patent ID: 8220444

Claim:
A system for improving the efficiency of an internal combustion engine of a vehicle, the system comprising: a first non-rotating device positioned within an air intake manifold upstream from a throttle chamber of the engine; and a second non-rotating device positioned within an exhaust manifold of the vehicle; wherein the first and second devices include: a tubular housing having an entrance end portion and an exit end portion, the housing being of a size to direct the flow of air through the air intake manifold or the exhaust manifold from the entrance end portion to the exit end portion; a plurality of longitudinal fins arranged within the housing protruding radially inward and extending from the entrance end portion towards the exit end portion, the fins being limited in their height such that a central portion of the devices is unobstructed by the fins, and the fins also having a curved profile along their length so as to generate a spiral airflow such that a differential air pressure is created to accelerate the rate of airflow through the vehicle.
