System and method for estimating and controlling temperature of engine component

摘要

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.

1. An engine system comprising:
an ambient condition module configured to generate a signal indicative of a state of ambient air during an operation of an engine; an operational parameter sensor configured to generate a signal indicative of one or more operational parameters associated with the engine, the one or more operational parameters including a temperature of an intake manifold of the engine; and a controller operably coupled to the ambient condition module and the operational parameter sensor, the controller configured to:
receive the signal indicative of the state of ambient air;receive the signal indicative of the one or more operational parameters associated with the engine;estimate a 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; andderate the engine maximum power rating when the estimated temperature of at least one of the valve, the piston, the liner, the cylinder head, and the pre-chamber exceeds a respective predetermined threshold.
