Abstract

[Problem] To avoid deterioration of an exhaust gas purification catalyst by suppressing influence of responsiveness of an apparatus. [Solution] An engine system comprises: an engine including a first fuel supplying portion that supplies a first fuel to a combustion chamber and a second fuel supplying portion that supplies a second fuel to the combustion chamber; an exhaust gas purification catalyst that is disposed in an exhaust passage of the engine and purifies components derived from the second fuel; a bypass passage that is connected to the exhaust passage and bypasses the exhaust gas purification catalyst; a control valve that adjusts a passage ratio of an exhaust gas of the engine through the exhaust gas purification catalyst and through the bypass passage; and a controller that controls the control valve; wherein a first mode in which the first fuel supplying portion is operated and a second mode in which operation of the first fuel supplying portion is stopped and the second fuel supplying portion is operated are provided to be selectable, and the controller controls the control valve to increase a passage ratio of the exhaust gas through the bypass passage when selection of the first mode is detected during operation in the second mode.
