Abstract: A system and method for cylinder deactivation in a multi-cylinder diesel engine comprises pumping air in to an intake manifold of the diesel engine using a turbocharger. Air is pumped in to the intake manifold using an intake air assisting device. And, fuel injection is selectively deactivated to at least one of the cylinders in the diesel engine. An intake valve and an exhaust valve is selectively deactivated for the at least one of the cylinders of the diesel engine.

Abstract: A friction loss management system for an engine, comprises a combustion engine comprising a crankshaft and a plurality of cylinders, a reciprocating piston assembly connected to the crankshaft, a fuel injector connected to an injection controller, an intake valve connected to an intake valve controller, and an exhaust valve connected to an exhaust valve controller. A control unit comprises at least one set of control algorithms configured to receive engine power demand data, and determine a number of cylinders of the plurality of cylinders for deactivation based on the received engine power demand data and further based on sensed or stored friction values for the plurality of cylinders. Determining the number of cylinders of for deactivation minimizes friction between the plurality of cylinders and their respective reciprocating piston assembly by selecting a cylinder combination of active cylinders and deactivated cylinders with the lowest total friction while meeting engine power demand.

Abstract: A rocker arm assembly can comprise a cam side rocker arm portion configured to selectively rotate about a pivot location. The cam side rocker arm portion can comprise a first socket above the pivot location, and a cam end configured to receive a lift profile from a cam lobe. A valve side rocker arm portion can be configured to rotate about the pivot location relative to the cam side rocker arm portion. The valve side rocker arm portion can comprise a second socket above the pivot location. A lost motion spring can span between the first socket and the second socket.

Abstract: A computer control network is connected to a multiple-cylinder engine and implements aftertreatment temperature management. Processors are configured to determine an aftertreatment temperature-efficient air to fuel ratio that satisfies the sensed power output request, determine an air to fuel ratio adjustment, select an in-cylinder exhaust gas recirculation technique, select at least one EGR cylinder of the multiple-cylinder engine to implement the in-cylinder exhaust gas recirculation technique, and control the intake valves to open and the exhaust valves to close for the selected at least one EGR cylinder to adjust the oxygen and particulate content of the exhaust gas by applying at least a second compression stroke of the respective reciprocating piston of the at least one EGR cylinder to the exhaust gas to push the exhaust gas through to the intake manifold.
