摘要： PROBLEM TO BE SOLVED: To provide a fuel injection valve manufacturable simply and compactly at a low cost by effectively heating fuel and forming a heater connector integrally with a coil connector in the fuel injection valve incorporating a heater. SOLUTION: This fuel injection valve 1 comprises an injection nozzle part 41 in which an injection hole 31 for injecting the fuel supplied from a fuel passage 88 is opened and closed by a valve needle 40 and an electromagnetic drive part 60 driving the valve needle 40 by energizing a coil 61. A fuel sump 87 is formed in the enlarged diameter part of a body case 33 on the upstream side of the fuel passage 88, and the heater 70 is disposed so as to surround the outer periphery of the valve needle 40. Since the heater 70 and a heater terminal connected to the heater are immersed in the fuel liquid, the heat of the heater can be efficiently transmitted to the fuel and the temperature rise of the heater terminal 15 can be suppressed. As a result, the connector 13 can be formed integrally with the coil terminal 14. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To enhance a deposit separating effect so as to prevent deterioration of performance of an internal combustion engine caused by an increase of a deposit accumulation amount, in a certain period of time immediately after changing from fuel injection by only an intake passage injection injector to fuel injection by a cylinder injection injector. SOLUTION: A cylinder injection condition setting section 530 sets conditions for fuel injection from the cylinder injection injector. The cylinder injection condition setting section 530 includes a normal condition setting part 532 and a deposit separating condition setting part 534. The deposit separating condition setting part 534 compares with the fuel injection conditions set by the normal condition setting part 532 and sets fuel injection conditions which are more effective in separating the deposit of the cylinder injection injector in an initial period from the point of changing from a PFI mode in which the cylinder injection is stopped to a cylinder injection mode. More specifically, as compared with the normal time fuel injection conditions, at least one of steps of raising the fuel injection pressure and increasing the number of times of fuel injection per cycle is performed.
