Air and fuel mixing apparatus

Patent ·
OSTI ID:5278875
This patent describes an apparatus for introducing gaseous fuel mixed with air into a tubular intake port of an internal combustion engine, and with the apparatus. It comprises a housing having a top wall with a top opening and a bottom wall with a bottom opening; means for mounting the housing to the tubular intake port; a control tube, through which may be drawn, adjustably mounted to the housing with one end extending through the top opening and another end positioned closely adjacent to and spaced from the housing bottom wall adjacent the bottom opening to form an annular gap therebetween; means through which gaseous fuel may be introduced into the housing about the control tube; and air flow restriction means for restricting air flow through the control tube during engine operations to create a pressure differential between the space inside the control tube and the space outside of the control tube within the housing for drawing gaseous fuel from the space within the housing about the control tube into the stream of air passing through the control tube and into the tubular intake port.
