Abstract: A method for controlling an engine in response to an increase in a load on the engine is disclosed. The engine includes a cylinder with a piston slidably disposed therein between a top dead center position and a bottom dead center position. The cylinder and the piston define a combustion chamber. The method includes initiating a first injection event and a second injection event. The first injection event includes introducing a first predetermined quantity of fuel into the combustion chamber at least 5 degrees before the piston reaches the top dead center position. The second injection event includes introducing a second predetermined quantity of fuel into the combustion chamber not earlier than 30 degrees after the piston moves away from the top dead center position.

Abstract: 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.

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.
