Abstract

An airflow enriching device for an internal combustion engine having an intake manifold. The airflow enriching device having a reaction chamber operable to hold a supply of liquid fuel at a selected level therein, and a vapor flow controller. The reaction chamber having an aerator submerged below said selected level of liquid fuel. The aerator for bubbling a supply of air through the fuel to form an enriched airflow. The vapor flow controller for controlling the flow of the enriched airflow into the intake manifold of the engine.
