Abstract: A ducted combustion system is disclosed. The ducted combustion system includes a combustion chamber bound by a flame deck surface of a cylinder head of an internal combustion engine and by a piston top surface of a piston disposed within the internal combustion engine. The system includes a fuel injector including one or more orifices, the one or more orifices injecting fuel into the combustion chamber as one or more fuel jets. The system includes one or more adjustable length ducts disposed within the combustion chamber between the flame deck surface and the piston top surface, the one or more adjustable length ducts being disposed such that each of the one or more fuel jets, at least partially, enters one of the one or more adjustable length ducts upon being injected into the combustion chamber.

Abstract: An engine system is provided. The engine system includes an ambient condition module configured to generate a signal indicative of a state of ambient air. The engine system also includes an operational parameter sensor configured to generate a signal indicative of one or more operational parameters associated with the engine. The engine system further includes a controller communicably coupled to the ambient condition module and the operational parameter sensor. The controller is configured to receive the signal indicative of the pressure of ambient air and the signal indicative of the one or more operational parameters associated with the engine. The controller estimates the temperature of at least one of a valve, a piston, a liner, a cylinder head, and a pre-chamber of the engine as a function of the received signals and parameters associated with fuel delivery to the engine.
