Abstract
An engine system is provided with an adjustment apparatus, which adjusts an engine output parameter; and an exhaust gas recirculation (EGR) passage, which connects an exhaust passage on a downstream side relative to exhaust gas purification apparatuses with an intake passage, and returns EGR gas as a part of exhaust gas to the intake passage. Restriction control is carried out to control the adjustment apparatus such that when a purification apparatus temperature is lower than a predetermined reference temperature, an upper limit value of the engine output parameter is set to lower than a maximum value and the engine output parameter has a value equal to or lower than the upper limit value, such that when the outside air temperature is low, the upper limit value is set to a lower value than when the outside air temperature is high.
