Abstract
A flow proportioning mixer is provided for mixing gaseous fuel and air, the mixer having therein a gas chamber adapted to discharge the gaseous fuel to a mixing channel, an air chamber adapted to direct the air into the mixing channel to mix with the fuel, a plunger reciprocally mounted in the mixing channel to define an annular passage in the channel, a pressure regulator for maintaining the pressure of the gas in the gas chamber and the air in the air chamber at a selected ratio, and a motor responsive to an engine exhaust content sensor to move the plunger in the mixing channel.
