Abstract: A twin jet carburetor includes a venturi having an elliptical cross section. Two needle jets and jet needles supply fuel to the airstream, allowing the system to operate as two carburetors in one body, but its overall size is much smaller. The elliptical shape venturi and pair of jets provide improved atomization and satisfy engine requirements at high rpm and wide-open throttle positions.
Abstract: A throttle controlled induction passage assembly is shown as having a body with an induction passage formed through the body and a throttle shaft extending transversely of the induction passage and carried by the body, the throttle shaft having an axis of rotation about which the throttle shaft is rotatable, a throttle valve is carried by the throttle shaft for rotation therewith, and an abutment arrangement for preventing the throttle shaft and throttle valve from experiencing undue movement relative to the induction passage in both directions along the axis of rotation; a suitable thrust bearing is provided to permit application of the body and shaft in any position.
