Abstract: Identifying position of a first rotating shaft may comprise a first position detection system and a second position detection system. A controller may be coupled to a first sensor and a second sensor and may identify the position of the first shaft using the identified shaft position from either the first detection system or the second detection system, whichever is identified faster. The first shaft may have a first wheel disposed thereon with targets and one or more gaps disposed about the first wheel. A second shaft may have a second wheel disposed thereon with targets and one or more gaps disposed thereon. The second wheel is in a fixed relationship relative to the first wheel. The first detection system may use data simultaneously from the first sensor and the second sensor to eliminate targets to determine position. The second detection system uses data only from the first sensor.

Abstract: Systems and methods for managing excessive intake flow path pressure and counter flow are implemented to support enhanced engine braking applications, such as 2-stroke or 1.5-stroke engine braking implementations where the intake flow path may be exposed to excessive transient pressures in the combustion chamber during activation or deactivation of an engine brake. Intake throttle, exhaust gas recirculation (EGR) valve, intake manifold blow-off valve, compressor bypass valve, exhaust throttle, turbocharger geometry or turbocharger waste gate may be controlled to effectuate counter flow management separately or in combination. Excessive transient conditions may also be prevented or managed by sequential valve motion in which brake motion activation occurs first and then exhaust valve main event deactivation occurs second. Delay between brake activation and main event deactivation may be facilitated using mechanical and/or hydraulic implements as well as electronically.

Abstract: A system and method of providing real-time calculation of heat flow in an engine. A piston is disposed in a cylinder of an engine block and movable relative to the cylinder in response to combustion inside the cylinder. A temperature of the combustion inside the cylinder, an average temperature of the wall of the cylinder, and a surface area of the wall of the cylinder based on timing of combustion are determined. An estimated temperature of the piston is derived from calculating a heat fraction to the piston in real-time, via a controller, based on the determined temperature of the combustion, the determined average temperature of the wall of the cylinder, and the determined surface area of the wall of the cylinder. A state of the engine is controlled based on the estimated temperature of the piston as derived from the real-time calculation of the heat fraction to the piston.
