A method of casting an assembly is provided that includes forming a structural insert, over-molding the structural insert with a temporary core, and positioning the over-molded structural insert within a cavity of a casting die. The over-molded structural insert is cast within a part, to form the assembly, and the temporary core is removed. The method may also include a temporary core configured to define an alloy flash trim location or locating features to position the structural insert within the cavity of the casting die. Further, the temporary core may define shared features with the structural insert. The part and structural insert may be dissimilar materials such as a part of an aluminum alloy material and a structural insert of a steel alloy material.

Method for providing preformed internal features, passages, and machining clearances for over-molded inserts

A system and method for improving engine emissions is described. In one example, engine emissions may be improved via increasing rotational resistance of a turbocharger while a temperature of an exhaust after treatment device is less than a threshold temperature. The system and method may reduce an amount of time for the after treatment device to reach an operating temperature.

Method and system for improving starting of a turbocharged engine

Systems and methods are provided for forming an engine comprising a thermoset composite engine block. One example method includes reinforcing the engine block with a plurality of metal strips, wherein a first portion of the plurality of metal strips are positioned in a substantially transverse direction of the engine block and a second portion of the plurality of metal strips are positioned in a substantially longitudinal direction of the engine block. The plurality of metal reinforcing strips may provide additional reinforcement to the engine block.

Reinforced composite cylinder block

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.

Multi-staged wastegate

A system and method for operating an engine turbocharger is described. In one example, the turbocharger is rotated in different directions in response to operating conditions. The system and method may reduce engine emissions.

Method and system for operating an engine turbocharger

An engine system is provided. The engine system includes a drive component coupled to a first end of a camshaft and mechanically coupled to a crankshaft and a cam phaser coupled to a second end of the camshaft and mechanically coupled to and spaced away from the drive component, the cam phaser configured to alter the timing of the camshaft.

Cam phaser system and method

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.

Approach for reducing overheating of direct injection fuel injectors

A method of controlling fuel supplied to an engine is provided. The engine includes at least one cylinder having a port injection fuel injector being supplied with fuel from at least one of a first fuel storage tank and a second fuel storage tank and a direct injection fuel injector being selectively supplied with fuel from one of the first fuel storage tank and the second fuel storage tank. The method includes at a first condition, supplying at least some of a second type of fuel from the second fuel storage tank to the direct injection fuel injector and supplying at least some of a first type of fuel from the first fuel storage tank to the port injection fuel injector, and at a second condition, supplying at least some of the first type of fuel from the first fuel storage tank to the direct injection fuel injector.
