Document Type and Number:
Japanese Patent JP6197822
Kind Code:
B2
Abstract:
A fuel supply device includes an injector (31), a fuel pressurization device and an ECU (36). The fuel pressurization device includes an electromagnetic valve (28). The fuel pressurization device is configured to pressurize a fuel in accordance with opening/closing of the electromagnetic valve and discharge the fuel toward the injector. The ECU is configured: to control the opening/closing of the electromagnetic valve to adjust the fuel amount discharged toward the injector; to execute an operation sound suppression control during a low-load operation of an engine by reducing an opening/closing frequency of the electromagnetic valve and increasing the fuel amount discharged for each opening/closing of the electromagnetic valve; not to execute the operation sound suppression control when a partial lift injection is in progress; and to execute the operation sound suppression control when the partial lift injection is not in progress.
