Abstract: A turbocharger control system of a vehicle includes a trigger module that generates a trigger signal when a transmission of the vehicle is in one of (i) park and (ii) neutral. A wastegate target module, in response to the generation of the trigger signal, sets a target opening of a turbocharger wastegate to a predetermined opening and independently of a position of an accelerator pedal. The predetermined opening is greater than zero percent opening of the turbocharger wastegate. A wastegate actuator module actuates the turbocharger wastegate based on the target opening of the turbocharger wastegate.

Abstract: An automotive vehicle includes a body with a central plane extending vertically along a longitudinal center of the body, with first and second sides on opposing sides of the central plane. The vehicle additionally includes a first movable member coupled to the first side. The first movable member has a first stowed position and a first deployed position. In the first deployed position the first movable member induces a first pressure differential between the first side and the second side. The vehicle also includes a first actuator configured to move the first movable member between the first stowed position and the first deployed position. The vehicle further includes a controller configured to, in response to satisfaction of a first operating condition, control the first actuator to move the first movable member from the first stowed position to the first deployed position.

Abstract: A gerotor assembly is provided which includes a crankshaft, an inner drive gear, an outer driven gear and a housing defining an oil groove. The inner drive gear defines a plurality of inner gear teeth. The outer driven gear defines a plurality of outer gear teeth operatively configured to engage with the inner gear teeth. The outer drive gear may define a plurality of passageways to form a hydrodynamic film between the outer driven gear and the housing. Alternatively, a high pressure oil pump may feed oil into the oil groove in order to distribute a hydrodynamic film.

Abstract: An engine includes a cylinder block defining a bank of cylinders having physically adjacent first and second cylinders. The engine also has a gas compressor configured to pressurize an ambient airflow for delivery to the first cylinder and the second cylinder. The engine additionally has intake valves configured to control delivery of the pressurized airflow as a first airstream to the first cylinder and a second airstream to the second cylinder for combustion therein. A firing interval for the two adjacent cylinders results in the first airstream temporally overlapping the second airstream. A charge-air cooler is configured to cool the pressurized airflow prior to delivery thereof to the first and second cylinders and includes a cold-side plenum for discharging the pressurized airflow toward the first and second cylinders. A partition in the cold-side plenum is configured to separate the first airstream from the second airstream and thereby minimize interference therebetween.

Abstract: An engine assembly generally includes an engine and an intake manifold. The engine includes a plurality of cylinders. The plurality of cylinders includes a pair of cylinders. The engine is configured to sequentially fire the pair of cylinders. The intake manifold defines a plurality of ports. Each port is in fluid communication with one of the plurality of cylinders. The plurality of ports includes a pair of ports. Each of the pair of ports is disposed in fluid communication with one of the pair of cylinders. The intake manifold further includes a baffle disposed between the pair of ports to restrict fluid flow within the intake manifold between the pair of ports.
