  "textContent": "An object of this invention is, even when executing WGV control, to stably control an air-fuel ratio in parallel therewith. An engine 10 includes a supercharger 36, a waste gate valve (WGV) 40 and the like. An ECU 60 calculates a wall-surface fuel adherence amount FMW that is an amount of fuel adhering to a wall surface of an intake port 20 based on a plurality of parameters including a degree of opening of the WGV 40 or an indicator corresponding to the degree of opening. The calculated wall-surface fuel adherence amount FMw is reflected in a fuel injection amount ETAUout. Thus, even when executing WGV control, a state of a blowback amount of exhaust gas that varies with the degree of opening of the WGV can be reflected in the wall-surface fuel adherence amount, in other words, the fuel injection amount, and thus a disturbance of the air-fuel ratio or the like caused by changes in the blowback amount can be suppressed.",
