Figure 2-2. Start Fuel Limit

Transient Overfuel

This feature allows the user to set the Maximum Fuel Limit near the rated engine
horsepower. The Transient Overfuel will allow exceeding this Maximum Fuel
Limit for a tunable percentage for a tunable time (Transient Time). This ensures
good transient load acceptance while maintaining safe steady-state-horsepower
limiting.
