Abstract
When an engine is to be started, operation of the engine is started with injection of fuel from a port fuel injection valve, without injecting fuel from an in-cylinder fuel injection valve (S100). If a gear rattling noise is produced (S110), the engine is operated with fuel injection, from the in-cylinder fuel injection valve, without injecting fuel from the port fuel injection valve (S120). This restrains occurrence of a gear rattling noise.
