Throttle plate for use with internal combustion engine
View Patent ↗A throttle plate for use with internal combustion engines comprised of a relatively thin piece of material so that installation of the throttle plate between the carburetor or throttle body and intake manifold of a vehicle does not require additional brackets or components to correct throttle cable linkage length or geometry. The throttle plate comprises a plate having apertures to accommodate pre-existing connectors and a perimeter that corresponds to connections between, and the geometry of, the carburetor or throttle body and intake manifold. The plate fits between the carburetor or throttle body and intake manifold and defines at least one airflow hole corresponding to the airflow path in the carburetor or throttle body. If there are multiple airflow paths between the carburetor or throttle body and intake manifold, then there will be multiple airflow holes. One or more vanes integral with the plate extend radially from the perimeter of each airflow hole toward its center. The plurality of vanes can be a variety of shapes, including helical and inclined, and extend into the airflow hole only to the extent they work in proximity of the throttle valve(s) and do not obstruct operation of the throttle valve in the throttle body. As air flows from the throttle valve(s) through the throttle plate and into the intake manifold, the vanes redirect laminar airflow into turbulent airflow.
1. A throttle plate comprising:
a. a plate defining at least one airflow hole for installation between a vehicle's throttle body and intake manifold; and
b. one or more vanes integral with the plate and extending radially from the perimeter of the airflow hole toward the center of the airflow hole, wherein the radial length of each vane is over 10 percent of the radius of the airflow hole and wherein each vane comprises a notch, a lower vane curve, and an upper vane curve.
2. The throttle plate of claim 1 wherein each vane is bent at a 45 degree angle.
3. The throttle plate of claim 1 wherein each vane is formed into a helical shape.
4. The throttle plate of claim 1 wherein the radial length of each vane is less than 17 percent of the radius of the airflow hole.
5. The throttle plate of claim 1 comprising a plurality of vanes that are evenly distributed around the circumference of the airflow hole.
6. The throttle plate of claim 1 comprising two or more plurality of vanes.
7. The throttle plate of claim 1 wherein the radial length of each vane is between 0.18 and 0.20 inches.
8. The throttle plate of claim 1 wherein the airflow hole comprises a diameter between 40 and 90 mm.
9. The throttle plate of claim 1 wherein the plate defines a first airflow hole and a second airflow hole and wherein a first plurality of vanes radially extends from the perimeter of the first airflow hole and toward the center of the first airflow hole and wherein a second plurality of vanes radially extends from the perimeter of the second airflow hole and toward the center of the second airflow hole.
10. The throttle plate of claim 1 wherein the plate is 0.032 inches thick.
11. The throttle plate of claim 9 wherein the first plurality of vanes comprises vanes having a radial length between 10 and 17 percent of the radius of the first airflow hole and wherein the second plurality of vanes comprise vanes having a radial length between 10 and 17 percent of the radius of the second airflow hole.
12. The throttle plate of claim 9 wherein the first plurality of vanes comprises vanes having a radial length between 0.18 and 0.20 inches and wherein the second plurality of vanes comprise vanes having a radial length between 0.18 and 0.20 inches.
13. The throttle plate of claim 1 further comprising one or more apertures to accommodate connectors.
14. The throttle plate of claim 1 wherein the plate further comprises a perimeter that cooperates with the connections between an automobile's throttle body and intake manifold.
15. The throttle plate of claim 1 wherein the plate further comprises a neck.
16. The throttle plate of claim 15 wherein the vanes extend from the neck toward the center of the airflow hole.
17. A method of increasing air turbulence in an internal combustion engine's intake manifold comprising introducing air through a throttle body past the throttle valve(s), into a throttle plate defining an airflow hole, and one or more radially extending vanes wherein the radial length of each vane is over 10 percent of the radius of the airflow hole and wherein each vane comprises a notch, a lower vane curve, and an upper vane curve.
18. The method of claim 17 wherein the radial length of each vane is less than 17 percent of the airflow hole.
19. The method of claim 17 wherein each vane is formed into a helical shape.
