Air filter for gasoline and diesel engines

#1. Field of the Invention

#The invention herein relates to a kind of air filter that drastically enhances the burning efficiency of gasoline and diesel engines.

#2. Description of the Prior Art

#The objective, features and effect of the invention herein will become more apparent in the following detailed description of the preferred embodiments, with reference to the accompanying drawings below.

#FIG. 1 is a dissectional structural drawing of the preferred embodiment of the invention herein.

#FIG. 2 is a photograph of fibre adhered with fine powder of naturally radioactive rare earth element mineral and used as filtering member under 700× electron microscope.

#The construction of the air filter for gasoline and diesel engines is described as follows:

#Referring to FIG. 1, the preferred embodiment of the invention herein comprises an outer box 1 having an air draw-in member 2, a ring-shaped filtering member 3 arranged inside the outer box 1 and having replaceable natural or synthetic fibres, an air silencer 4 arranged internal to the filtering member 3, a cap 5 mounted on top of the outer box 1 through spacer 6, a butterfly nut 7 protrudingly arranged at the center of bracket 8 for securing the cap 5, filtering member 3 and air silencer 4. FIG. 1 illustrates only one example of the air filter. The construction of the air filter in this invention is not significant and may be altered at will.

#The filtering member 3 arranged inside outer box 1 is incorporated with fine powder of naturally radioactive rare earth element mineral. The rare earth element mineral refers to any of the seventeen elements including those with atomic numbers of 57-71, namely lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, ytterbium, and thulium, plus scandium and yttrium. All these elements produce air-purifying negative ions under natural state.
