<p>The charge for an internal combustion engine is comprised of a mixture of heated fuel-vapor-laden air and ambient air drawn through an air filter in a conventional manner. The vapor-laden air is obtained by first heating air in a heat exchanger (15) to a given temperature by picking up heat from the engine"s exhaust. The heated air is then drawn through a fuel-saturated air permeable element (21). Fuel is delivered to the air permeable element (21) and continuously circulated thereover. As the heated air passes through the element (21) it becomes laden with fuel-vapor; and, is cooled to a second temperature that is substantially below the first. The cooled fuel-vapor-laden air is then mixed with additional air and the resulting charge is delivered to the engine"s intake manifold. </p> |
