Abstract
A warm-up system for an exhaust gas apparatus includes the exhaust gas apparatus having a turbocharger provided with a turbine, a first exhaust gas control catalyst provided downstream of the turbine, a bypass passage bypassing the turbine, and an adjustment unit adjusting a turbine inflow exhaust gas flow rate and an electronic control unit. The electronic control unit is configured to perform a warm-up control which warms the turbine by controlling the turbine inflow exhaust gas flow rate, by using the adjustment unit, to reach a flow rate higher than zero and lower than the post-warm-up flow rate when an operating state of the internal combustion engine remains constant, such that a warmed state of the first exhaust gas control catalyst is maintained after the first exhaust gas control catalyst is warmed.
