Abstract: Systems and methods to update the calibration data of a control system includes a calibration system. The calibration system includes a first cloud connected application system structured to communicatively couple to a second cloud connected application system, determine, via at least one of the first cloud connected application system or the second cloud connected application system, a calibration update request corresponding to a control system, generate custom calibration data including preference data based on at least one of the calibration update request or the preference data, and provide the custom calibration data during at least one of an active engine state or an inactive engine state, wherein the custom calibration data is transmitted from the second memory portion to the first memory portion in response to the inactive engine state.

Abstract: Systems, methods and techniques for exhaust gas recirculation are provided. The system includes controlling the mixing of exhaust flow from at least one cylinder of an engine with air in an air intake system prior to combustion in response to an EGR fraction deviation condition. The exhaust flow from the at least one cylinder is accumulated prior to mixing and distributed into the intake air system in a controlled manner to mitigate or prevent the EGR flow from deviating from an expected EGR fraction.

Abstract: Disclosed herein is an internal combustion engine includes a cylinder with a mid-stop shelf and a liner positioned within the cylinder. The liner includes a seat supported on the mid-stop shelf. Further, the liner defines a piston channel. The engine also includes a coolant conduit between the cylinder and the liner. The coolant conduit located above the mid-stop shelf and seat. Additionally, the engine includes a piston with a head portion and a skirt portion. The piston is movable within the piston channel between an upper-most position and a lowermost position. In the upper-most position, the skirt portion of the piston is positioned below the mid-stop shelf and seat.

Abstract: An EGR system for an internal combustion engine has a separate, secondary high-temperature cooling loop, in addition to a primary cooling loop. In the secondary cooling loop, coolant flows through a secondary high-temperature exhaust gas cooler, which is located upstream of the primary exhaust gas cooler. A large amount of heat is transferred from the exhaust gases to the coolant in the secondary high-temperature cooling loop. The heat absorbed by the high-temperature coolant is rejected in a secondary high-temperature radiator. Heat absorbed by the primary coolant is rejected in a primary radiator. The two radiators occupy the same amount of frontal area as a single radiator used in a conventional single-stage EGR cooling system, but overall reject more heat to the ambient. In an alternate arrangement, the EGR system for a liquid-cooled internal combustion engine has a single exhaust gas cooler which is cooled by an EGR cooling loop that is independent of the engine cooling system.
