Abstract: A system for increasing the power of cars by increasing the oxygen content in the intake manifold supply using a zeolite filtration system. This system does not rely on the conventional method of injecting pure oxygen from a tank or using hydrolysis from water. This actually converts the air to a higher oxygen content as it flows to the intake manifold in a car. The practical idea of this is to increase the power of the engine without increasing displacement or to have the engine downsized with less displacement while still having the same power. It also has the application in cars or trucks to almost completely diminish NOx emissions. This is especially useful in tractor trailers because then you can forgo expensive aftertreatment systems to reduce NOx, which sometimes cost more than the engine itself, greatly reducing the cost of a tractor trailer and also doing the things mentioned above.
