Abstract: A precombustion conditioning device for gasoline fired internal combustion engines comprising at least one cupped or dished foraminous member disposed across the fuel-air intake passageway of the engine between the carbuetor and fuel-air inlet of the engine, with the foraminous member being electrically insulated from both the carburetor and the engine, with the foraminous member being electrically connected to the positive terminal of a direct current power source, such as the automobile battery, and the negative terminal of the power source being connected to the engine and hence the inside wall of the intake manifold.

Abstract: A precombustion conditioning device for gasoline fired internal combustion engines comprising at least one cupped or dished foraminous member disposed across the fuel-air intake passageway of the engine between the carburetor and fuel-air inlet of the engine, and mounted in a carrier formed from an electrically insulating material that also carries an electrogenetic direct current power surce, with the foraminous member being electrically connected to the positive terminal of the direct current power source and the negative terminal of the power source being connected to the engine and hence the inside wall of the intake manifold.

Abstract: A high temperature gasket structure particularly useful in automotive carburetors but useful in other applications in which the gasket body is formed from a special type of semirigid asbestos board having a minimal elastomeric binder content, and with the bolt hole areas densified in part by embedded steel washers in the gasket body to minimize carburetor flange flexing and maintain high torque retention under heat. The gasket structure is intended to serve as a heat insulator and as a partial sound and vibration dampener and can be formed, when required, with upstanding beads to further minimize flexing of the carburetor flange while maintaining a seal.
