。 a mixture ratio correction coefficient storage means that stores a mixture ratio correction coefficient corresponding to the engine speed and load; a search means that searches for a mixture ratio correction coefficient from the engine speed and load; and a searched mixture ratio correction coefficient. In the mixture ratio control device for a turbocharged engine, the mixture ratio correction coefficient storage means is configured to have two types of mixture ratio correction coefficients with different values. In addition to providing high rotation,
Switching means is provided for switching the search target of the search means from the commonly used first mixture ratio correction coefficient storage means to the second mixture ratio correction coefficient storage means having a rich characteristic when the high load state continues for a predetermined time or more. A mixture ratio control device for an engine equipped with a turbocharger.
