A system includes an engine adapted to output a torque, a parasitic load adapted to receive a portion of the torque from the engine, and a controller communicably coupled to the parasitic load. The controller is configured to determine an actual exhaust temperature value of an exhaust gas flow exiting the engine and a minimum fuel amount to be injected into the engine. The controller is configured to compare the actual exhaust temperature value with an exhaust temperature threshold value of the exhaust gas flow to determine a first difference between the actual exhaust temperature value and the exhaust temperature threshold value. The controller is configured to determine a target torque output of the engine based on the first difference and the minimum fuel amount. The controller is configured to cause the torque to be increased to attain the target torque output using the parasitic load.

System including engine and method of operating engine

An interlock lever for actuating a latch member of a machine is disclosed. The latch member is configured to lock a hood of the machine in a closed position thereof. The machine has an input member being movable in a first direction to move the hood towards an opened position and a second direction to move the hood towards the closed position. The interlock lever includes a body coupled to a frame of the machine and a slot defined in the body. The body is movable between a first position and a second position. In the second position of the body, the slot allows movement of the input member in the first direction and actuates the latch member to allow the hood to move from the closed position. In the first position of the body, the slot prevents movement of the input member in the first direction.

A mounting member for an actuator of a machine is disclosed. The actuator has a cylinder defining a longitudinal direction and a motor disposed adjacent to a mounting end of the cylinder. The actuator has a first angular orientation and a second angular orientation about the longitudinal direction with respect to the mounting member. The motor is disposed proximal to the mounting member in the first angular orientation and disposed distal to the mounting member in the second angular orientation. The mounting member includes a base portion to couple to a frame of the machine and a bracket portion extending from the base portion. The bracket portion is coupled to the mounting end of the cylinder. The mounting member further includes a guide portion extending from the base portion to prevent coupling of the actuator to the bracket portion in the first angular orientation.
