Abstract: A method includes detecting a change in a loading condition on an engine based on use of an implement system including a pump driven by the engine, an actuator fluidly coupled to the pump, and an implement repositionable with the actuator. The change in the loading condition is detected based on a variation in a command signal from a joystick that controls movement of the implement, an outlet pressure of the pump, a displacement of the pump, and/or an engagement signal of a clutch positioned to selectively couple the pump to the engine. The method further includes commanding a fueling system to increase an amount of fuel provided to the engine and/or an air handling system of the machine to increase an amount of air and/or a boost pressure of the air provided to the engine in response to detection of an increasing loading condition based on the variation.

Abstract: A method for controlling air and fuel supply to an engine of a machine includes: detecting, by a processing circuit, a change in a loading condition on the engine of the machine based on use of an implement system of the machine; and providing, by the processing circuit, a command to (i) a fueling system of the machine to increase an amount of fuel provided to the engine by the fueling system and (ii) an air handling system of the machine to increase at least one of (a) an amount of air or (b) a boost pressure of the air provided to the engine by the air handling system in response to an increase in the loading condition.
