SYSTEM AND METHOD FOR ESTIMATING AND CONTROLLING TEMPERATURE OF ENGINE COMPONENT

摘要

An engine system is provided. The engine system includes an ambient air pressure sensor configured to generate a signal indicative of a pressure 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 air pressure sensor 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 in a single fuel cycle of the engine.

1. An engine system comprising:
an ambient air pressure sensor configured to generate a signal indicative of a pressure of ambient air during an engine operation; an operational parameter sensor configured to generate a signal indicative of one or more operational parameters associated with the engine; and a controller communicably coupled to the ambient air pressure sensor and the operational parameter sensor, the controller configured to:
receive the signal indicative of the pressure of ambient air;receive the signal indicative of the one or more operational parameters associated with the engine; andestimate 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 in a single fuel cycle of the engine.
