Abstract: An engine control system includes a cylinder control module and a pump control module. The cylinder control module selectively deactivates cylinders of an engine. In response to a determination that at least one of the cylinders is deactivated, the pump control module: selectively increases a target displacement for an oil pump that is driven by a balance shaft of the engine; and selectively adjusts displacement of the oil pump based on the target displacement.

Abstract: A control system for an engine includes a torque modifier module that selects one of a plurality of torque modifier values based on variations in an accessory load. A torque calculating module calculates a maximum torque value for operation in a cylinder deactivation mode based on the selected one of the plurality of torque modifier values. A torque control module selectively switches the engine between the cylinder deactivation mode and a cylinder activation mode based on the maximum torque value.

Abstract: A crankshaft assembly for a vehicle, a method of operating a crankshaft assembly, and a method of manufacturing a crankshaft assembly. The crankshaft assembly includes a crankshaft, a first pin bearing journal and a main journal, an oil passage having a main passage wall, the oil passage extending from the first pin bearing journal to or through the main bearing journal, a crankpin exit hole located in the main passage wall, and a blocking element positioned in the oil passage, wherein the blocking element is located in a radially outward position with respect to the crankpin exit hole.

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.
