ABSTRACT:
A method and apparatus for increasing fuel economy of a diesel fuel engine in which an aerator (40) bubbles air through diesel fuel (F) in a diesel fuel tank (T) to generate diesel fuel fumes in the ullage (U). In a turbocharged diesel engine, the fumes are directed by a valve (60) to fume injectors 86 and injected just before the turbo charger fan (32). In a normally aspirated engine, the fumes are directed by a valve (160) to the intake manifold (124).
