Abstract:
In the present invention, when there has been a PM collection filter 7 regeneration request , an ECU 14 closes a flow rate regulation valve 12 and then starts up an electromagnetic pump 11 that pressure-feeds unburned fuel 10 to an injector 8. Subsequently, the ECU 14 performs control to adjust the number of rotations of the electromagnetic pump 11 on the basis of preset map data so that a measurement value X of a pressure sensor 13 matches a target pressure value A within a predetermined range.
