摘要： A method of controlling fuel supplied to an engine is provided. In one example, a cylinder includes port and direct fuel injection. The method includes supplying a second fuel type from a second tank to the direct injector and supplying a first fuel type from a first tank to the port injector; and responsive to mis-fueling, supplying the first fuel type from the first tank to the direct injector. In response to receiving an indication of a mis-fuel, the direct fuel injector may be supplied with the second type of fuel from the second fuel storage tank. By supplying at least some fuel to the direct injector from a different source, fuel may be supplied to the DI fuel injector at various conditions to cool the DI fuel injector. In this way, overheating of the DI fuel injector may be reduced.

摘要： Embodiments for controlling boost pressure are provided. In one example, a method of controlling a turbocharger of an engine via a multi-staged wastegate comprises during a first condition, actuating a first stage of the wastegate based on boost pressure generated by the turbocharger, and actuating a second stage of the wastegate based on a temperature of a catalyst downstream of the turbocharger. In this way, catalyst heating and boost control may be provided by a common wastegate.
