ABSTRACT:
A control apparatus for an internal combustion engine includes an exhaust gas recirculation unit; an intercooler that is provided in the intake passage, at a position downstream of a position to which the exhaust gas is recirculated back; a bypass passage through which an intake air flow bypasses the intercooler. When it is determined that the pH of the condensed water obtained from the exhaust gas is at the level at which the intercooler corrodes in the state where the exhaust gas is recirculated back by the exhaust gas recirculation unit, the control apparatus executes a control for cutting off an intake air flow toward the intercooler to direct the intake air flow only to the bypass passage. Thus, it is possible to ensure reliability of the intercooler.
