Abstract

An engine control device () having a supercharger () includes an injection controller () that controls injections of fuel through a cylinder injection valve () and through a port injection valve (), based on a rotation speed Ne of an engine (), and a variable valve controller () that controls a variable valve actuating mechanism () based on the rotation speed Ne. The variable valve controller () provides a valve overlap period in a first rotation speed region, and shortens the valve overlap period in a second rotation speed region of greater rotation speeds Ne than in the first rotation speed region. The injection controller (), in the period during which the rotation speed is shifting from the first rotation speed region to the second rotation speed region, carries out a cylinder injection and a port injection, and advances timing for injecting the fuel through the port injection valve ().
