Abstract

See full text

An internal combustion engine (1) has an electric heating catalyst (5) in an exhaust passage (2). When it is detected that a door has been opened, the electric heating catalyst (5) is preheated. If power of an engine controller (8) is lost during the preheating, information on an estimated temperature, which is stored in the engine controller (8), is lost. The engine controller (8) forbids energization of the electric heating catalyst (5) until a cooling period necessary for temperature of the electric heating catalyst (5) to fall elapses after recovery of the power of the engine controller (8). After the cooling period elapses, the preheating is started again.
