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. A spout extends outwardly from the tubular member and at least two magnets disposed longitudinally along the tubular member are provided for exposing the water to a magnetic field as the water passes through the tubular member and spout. Various alternate controllers facilitate the use of additional driving schemes.
