PROBLEM TO BE SOLVED: To improve an in-cylinder combustion state, regarding a control device controlling fuel pressure of an engine.SOLUTION: A calculation unit 2 calculates acceleration intensity of a vehicle mounted with an engine 10. Also, a control unit 3 executes rail pressure control that makes fuel pressure of the engine 10 lower and makes a reduction amount of fuel pressure per unit acceleration intensity smaller, as the acceleration intensity calculated by the calculation unit 2 is made larger.SELECTED DRAWING: Figure 1 |
