Abstract: An integrated exhaust manifold for use with an internal combustion engine and dual scroll turbocharger. The integrated exhaust manifold includes a first exhaust passageway fluidly connected between a first pair of piston cylinders and the dual scroll turbocharger for transporting exhaust gas from the first pair of piston cylinders to a first input of dual scroll turbocharger. The integrated exhaust manifold includes a second exhaust passageway fluidly connected between a second pair of piston cylinders and the dual scroll turbocharger for transporting exhaust gas from the second pair of piston cylinders to a second input of the dual scroll turbocharger. The second exhaust passageway is fluidly independent from the first exhaust passageway and the first and second exhaust passageways are positioned to define a septum area therebetween.

Abstract: A variable compression ratio (VCR) internal combustion engine includes an engine block defining a cylinder and a cylinder head mounted to the engine block and defining at least a part of a combustion chamber. The engine also includes a reciprocating primary piston arranged inside the cylinder and configured to compress a mixture of air and fuel and a crankshaft arranged in the engine block and rotated by an application of a combustion force to the primary piston. The engine additionally includes a secondary piston mounted in the cylinder head, movably with respect to the combustion chamber and a mechanism configured to shift the secondary piston in the cylinder head and thereby vary a volume of the combustion chamber and a compression ratio of the engine. A vehicle employing such an engine is also disclosed.

Abstract: An engine assembly includes an oil pan including an oil pan body defining a cavity. The oil pan body includes a dividing wall separating the cavity into a first compartment and a second compartment. The dividing wall defines a compartment opening extending therethrough, and the compartment opening fluidly interconnects the first compartment and the second compartment. The engine assembly also includes an oil pump at least partially disposed inside the first compartment of the oil pan. The oil pump includes a pump pickup conduit in fluid communication with the first compartment. The engine assembly additionally includes a temperature sensor disposed inside the pump pickup conduit of the oil pump. The temperature sensor can measure the temperature of oil flowing into the oil pump. In other words, the temperature sensor can sense the temperature of the oil pumped in the engine.

Abstract: An engine assembly includes an oil pan having an oil pan body. The oil pan body includes an inner pan surface defining a cavity configured to collect oil and an outer pan surface opposite the inner pan surface. Further, the oil pan includes a dividing wall disposed within the cavity and coupled to the oil pan body. The dividing wall divides the cavity into a first compartment and a second compartment. The oil pan defines an opening extending through the dividing wall. A valve is disposed in the opening and can move between an open position and a closed position. When the valve is in the open position, the first compartment is in fluid communication with the second compartment. When the valve is in the closed position, the valve blocks fluid flow between the first compartment and the second compartment via the opening.

Abstract: A variable compression ratio (VCR) internal combustion engine having a compression stroke and an expansion stroke includes an engine block defining a cylinder and a cylinder head mounted to the engine block and defining at least a part of a combustion chamber. The VCR engine also includes a reciprocating piston arranged inside the cylinder and configured to compress a mixture of air and fuel and receive a combustion force, wherein the compression stroke of the piston defines a compression ratio of the engine. The VCR engine additionally includes a six-bar linkage mechanism configured to operatively connect the piston to the engine block, articulate on seven distinct parallel axes, decouple the compression stroke from the expansion stroke, and continuously and selectively vary the compression stroke of the piston and the compression ratio of the engine.
