Abstract
An internal combustion engine in which when an ECU receives an engine stop command by an ON-operation of an engine stop switch, a supply of fuel from an injector to a fuel reformation chamber is stopped while a supply of fuel from an injector to a combustion chamber is continued, and the residual amount of a reformed fuel in passages is estimated, in this state. When the estimated residual amount reaches a predetermined amount or zero, the fuel supply from the injector to the combustion chamber is stopped, and an internal combustion engine is stopped.
