Document Type and Number:
WIPO Patent Application WO/2005/083258
Kind Code:

Abstract:
A fuel injection mechanism capable of injecting an appropriate quantity of fuel from an electronic control fuel injector by returning vapor existing in a fuel passage back to the fuel tank even if a fuel tank is located lower than the electronic control fuel injector. The fuel tank (10) is located lower than the electronic control fuel injector (12), a fuel storage chamber (18) supplied with fuel from the fuel tank (10) is located higher than the electronic control fuel injector (12) and fuel stored in the fuel storage chamber (18) is supplied to the electronic control fuel injector (12) through a fuel supply passage (24). The fuel storage chamber (18) and the fuel tank (10) are interconnected through a first fuel return passage (30) for overflowing fuel in the fuel storage chamber (18) and discharging vapor. A second fuel return passage (36) for returning the excess fuel of the electronic control fuel injector (12) is interconnected to the fuel storage chamber (18) or the first fuel return passage (30) higher than the position at which the fuel storage chamber (18) and the first fuel return passage (30).
