摘要： PROBLEM TO BE SOLVED: To perform fuel leakage diagnosis within a return piping with the objective of returning fuel from high-pressure fuel piping to high-pressure fuel pump upstream section. SOLUTION: If it is determined that a return piping fuel leakage diagnosis starting means performs fuel leakage diagnosis within a return piping, and a drive of a pressure adjusting within return piping means is needed, a drive of a low-pressure fuel pump is started (T1409 in the figure). Along with this, a pressure within the return piping increases. In the figure, however, values detected by a pressure sensor within return piping are expressed by a broken line 1403, and return piping fuel leakage diagnosis values preset or calculated through a predetermined calculation are expressed by 1401. From the return piping fuel leakage diagnosis values, if values detected by the pressure sensor within return piping indicate a fixed difference or ratio, it will be determined that the fuel leakage within the return piping has occurred.
