Abstract
A controlled engine shutdown method is disclosed that includes monitoring exhaust system temperature, monitoring operator shutdown commands, and delaying engine shutdown based on exhaust system temperature. The method can include inhibiting any process that affects exhaust temperatures, for example DPF regeneration. The method can use a shutdown timer, allow operator override of the shutdown delay, and display a delay notification message. The method can also include predicting when an engine shutdown is expected, and delaying or aborting any process that would affect exhaust temperatures when an engine shutdown is predicted. Predicting can include monitoring various machine states, determining an average activity interval for the machine, determining a geographic shutdown area, determining a shutdown time of day and/or monitoring a machine fluid level.
