Abstract

An engine system includes: a first flow-rate-control-valve configured to control a flow rate of air supplied to an engine; a first fuel-injection-valve configured to inject fuel toward the engine; a reformer configured to reform fuel to generate a reformed gas containing hydrogen; a second flow-rate-control-valve configured to control a flow rate of air supplied to the reformer; a second fuel-injection-valve configured to inject fuel toward the reformer; and a control unit configured to control the first flow-rate-control-valve, the first fuel-injection-valve, the second flow-rate-control-valve, and the second fuel-injection-valve based on a command value for the engine. When the command value changes during operation of the engine, the control unit sets a target-opening-degree of the first flow-rate-control-valve corresponding to the command value as a first target-opening-degree, sets a target-opening-degree of the second flow-rate-control-valve corresponding to the command value as a second target-opening-degree, and controls the first flow-rate-control-valve and the second flow-rate-control-valve so that a timing at which an opening-degree of the first flow-rate-control-valve reaches the first target-opening-degree is later than a timing at which an opening-degree of the second flow-rate-control-valve reaches the second target-opening-degree.
