    Abstract: A vehicle includes an engine assembly configured to power a vehicle. The engine assembly defines a first engine end and a second engine end opposite the first engine end. The first engine end is spaced apart from the second engine end along a first direction. The engine assembly defines a third engine end and a fourth engine end opposite the third engine end. The third engine end is spaced apart from the fourth engine end along a second direction. The second direction is substantially perpendicular to the first direction. The vehicle further includes a steering assembly disposed in close proximity to the engine assembly. The steering assembly includes a steering body disposed closer to the first engine end than to the second engine end.

    Abstract: An engine assembly includes an engine block having a first bank of cylinders and a second bank of cylinders. A crankshaft is supported by the engine block and is configured to be driven by torque due to combustion energy in the first and second banks of cylinders. A first set of valves is operable to control air flow into and out of the first bank of cylinders. Camshafts driven by the crankshaft are operatively connected to the first set of valves to control opening and closing of the first set of valves. A second set of valves is operable to control air flow into and out of the second bank of cylinders. A controller is operatively connected to the second set of valves and is configured to vary at least one of lift, duration, and timing of the second set of valves based on commanded torque at the crankshaft.

    Abstract: Disclosed are integrated exhaust manifold (IEM) cylinder heads, methods for making and methods for using IEM cylinder heads, and motor vehicles with an engine and IEM cylinder head assembly. Disclosed, for example, is an IEM cylinder head for a motor vehicle with an engine and an exhaust system. The IEM cylinder head includes a body that mounts to the engine's cylinder block. The cylinder head body integrally defines: multiple chamber surfaces each aligning with a cylinder bore and piston to define a combustion chamber; multiple exhaust ports each communicating with a cylinder bore to evacuate exhaust gas therefrom; multiple exit ports communicating with the exhaust system to evacuate exhaust gas from the cylinder head; and multiple exhaust runners each extending from an exhaust port to one exit port. These exhaust runners are fluidly isolated from each other to each transmit exhaust gases from a single one of the cylinder bores.

    Abstract: A camshaft assembly for an internal combustion engine includes a camshaft, a first lobe set, and a second lobe set, extending along, and rotatable about, a cam axis. The first lobe set includes a first, second, and third lobe. The second lobe set includes a first and second lobe. The first lobe set is movable along the cam axis between a first, second, and third position. The second lobe set is movable along the cam axis between a first and second position. The first and second position of each of the first and second lobe sets corresponds to lift of a respective valve stem in the engine. The third position of the first lobe set corresponds to zero lift of the respective valve stem to provide cylinder deactivation of a corresponding cylinder within the engine.

    Abstract: A crankshaft includes a plurality of crankpins. The crankpins are defined on the crankshaft and are longitudinally spaced apart from each other along a rotational axis. Each of the crankpins is configured to be operatively connected to a piston of an engine including a plurality of cylinders. The engine is configured to deactivate one of the cylinders. At least two of the crankpins are substantially aligned with each other along a pin axis. At least one of the crankpins is rotationally offset from the pin axis in a rotational direction of the crankshaft such that the engine has an even firing order even when one of the cylinders is deactivated.

    Abstract: An inlet manifold comprises a plenum, a pair of intermediate runners, and two pair of terminal runners. A common EGR passage is in fluid communication with a pair of EGR injectors, each being in fluid communication with a respective intermediate runner. Each intermediate runner receives a split stream of EGR from its respective EGR injector and combines the split stream of EGR with a split stream of inlet air from the plenum to form an EGR-loaded stream. Each intermediate runner is in fluid communication a pair of terminal runners for distributing its EGR-loaded stream among the terminal runners.

    Abstract: An engine assembly includes a cylinder head having an intake side and an exhaust side opposite the intake side. The cylinder head has an intake port, an exhaust port, and a combustion chamber in fluid communication with the intake port and the exhaust port. The engine assembly further includes a port fuel injector coupled to the cylinder head. The port fuel injector is disposed closer to the exhaust side than to the intake side of the cylinder head. Further, the port fuel injector is fluid communication with the intake port to allow fuel to be injected directly into the intake port. The engine assembly further includes a direct fuel injector coupled to the cylinder head. The direct injector is in fluid communication with the combustion chamber to allow fuel to be injected directly into the combustion chamber.
