Document Type and Number:
Japanese Patent JP7243431
Kind Code:
B2
Abstract:
To secure combustion stability while accurately removing deposits from an injection hole of a fuel injection valve.SOLUTION: An ECU 20 includes an injection control part 22 for controlling an injector 15, a deposit estimation part 27 for performing processing to estimate a deposit accumulation amount in an injection hole 15B of the injector 15 (step S4), a fuel temperature deriving part 28 for deriving the temperature of fuel, and a fuel pressure control part 26 for allowing the fuel pressure rise of the injector 15 when the deposit accumulation amount is equal to or greater than a predetermined value. The fuel pressure control part 26 controls a high pressure fuel pump 153 to allow the fuel pressure rise when the deposit accumulation amount estimated by the deposit estimation part 27 is equal to or greater than the predetermined value, and restricts the fuel pressure rise (steps S6, S7) when the fuel temperature derived by the fuel temperature deriving part 28 is higher than a preset reference temperature.SELECTED DRAWING: Figure 13
