FUEL SUPPLY APPARATUSES

摘要

It is an object of the present invention to inhibit production of vapor within fuel when an engine is at a high temperature and to inhibit change of amount of the fuel injected from an injector. A fuel supply apparatus according to the present invention includes vapor production determining means (3) for determining whether or not the vapor of the fuel is producible, and control means (ECU) for operating a passage resistance adjusting means (47) of a pressure adjusting mechanism (40) to cause increase of the pressure of the fuel supplied to an injector (5) insomuch as the production of the vapor is inhibited when the vapor production determining means (3) has determined a vapor producible condition.
