Abstract
An on-board vapor reclamation system and method includes an air inlet into an on-board diesel fuel tank and a fuel vapor/air mixture outlet from the fuel tank. A pump or a suction fan is operable to drive air from the air inlet through the tank and a fuel vapor/air mixture out the fuel vapor/air mixture outlet at a flow rate which maintains a fuel vapor concentration in the tank to less than a predetermined value corresponding to the lower explosive limit to reduce fire and explosive hazards and to reduce harmful emissions. A condenser subsystem is fluidly connected to the fuel vapor/air mixture tank outlet and is configured to condense fuel vapor in the fuel vapor/air mixture delivered to the condenser subsystem at the required flow rate. Condensed fuel vapor from the condenser subsystem is returned to the fuel tank to save fuel and increase mileage.
