Abstract: A powertrain includes a housing and a crankshaft-balancing assembly that is at least partially disposed inside the housing. The crankshaft-balancing assembly includes a crankshaft rotatable about a longitudinal axis. The crankshaft-balancing assembly further includes a drive member secured to the crankshaft. The crankshaft-balancing assembly also includes a first shaft rotatable about a first pivot axis. The first shaft is rotatable in response to rotation of the crankshaft. The crankshaft-balancing assembly includes a weight member that extends from the first shaft. The weight member is positioned along the first shaft to balance the crankshaft during rotation of the crankshaft and the first shaft. The crankshaft-balancing assembly also includes a drive member that surrounds the first shaft and a portion of the weight member. The drive member of the first shaft defines a void that opposes the portion of the weight member.

Abstract: A fluidic valve assembly is disposed in a thermal management system for an internal combustion engine, and includes a unitary housing including a first rotary valve, a second rotary valve and a third rotary valve. The first, second and third rotary valves include a respective first, second and third rotatable valve body that is coupled to a respective first, second and third actuator. The first, second and third rotary valves are disposed to regulate fluidic flow between heat exchange elements of the thermal management system. The second and third rotary valves are coaxially disposed about a first axis of rotation and the first rotary valve is coaxially disposed about a second axis of rotation, with the first axis of rotation being non-parallel to the second axis of rotation.

Abstract: A heat exchanger includes a heat exchanger body arranged along an axis and having an external surface in contact with a surrounding first fluid. The body defines a first fluid passage centered on and extending along the axis. The body also defines a second fluid passage extending parallel with respect to the axis and spaced away from the axis by a second passage distance, and a third fluid passage extending parallel with respect to the axis and spaced away from the axis by a third passage distance. The first, second, and third passages are parallel to one another, while the third passage distance is greater than the second passage distance. Each of the first and third passages is configured to accept a flow of a second fluid and the second fluid passage is configured to hold a volume of air to thermally insulate the first passage from the third passage.

Abstract: An internal combustion engine includes an engine block defining a plurality of cylinders. A cylinder head casting is mounted to the engine block. The cylinder head casting defines intake ports and exhaust ports communicating with the plurality of cylinders. The cylinder head casting defines an air passage in connection with the intake ports and includes elongated extruded cooling elements defining liquid coolant passages integrated into the cylinder head casting within the air passage for cooling intake air passing through the air passage.

Abstract: An internal combustion engine includes an engine block including a plurality of cylinders. A cylinder head is mounted to the engine block and includes intake and exhaust passages in communication with the plurality of cylinders. A cylinder head cover is mounted to the cylinder head and defines a cavity between the cylinder head and the cylinder head cover. An oil passage is disposed in the cavity and includes at least one oil jet for spraying oil at a surface of the cylinder head that is heated by the exhaust passages.
