Abstract
A straight bore butterfly valve carburetor with accelerator assist module includes a butterfly valve carburetor with a straight bore and a vacuum accelerator assist module. The butterfly valve carburetor with a straight bore includes a substantially straight bore intake chamber. The venturi in the intake chamber is eliminated. The vacuum accelerator assist module includes two housing halves, a diaphragm and means for biasing the diaphragm into the fuel chamber. The diaphragm creates a vacuum chamber and a fuel chamber. The vacuum chamber communicates with the substantially straight bore intake chamber and the fuel chamber communicates with a fuel metering chamber of the carburetor. A vacuum is applied to the diaphragm at engine idle, which overcomes the means for biasing. When the butterfly valve is opened, the vacuum collapses and fuel is feed into the substantially straight bore intake chamber to increase engine speed.
