Abstract:
1. A method of operating a vehicle equipped with a pneumatic booster system, said pneumatic booster system being configured to inject compressed air into an intake of an engine of the vehicle during a current pneumatic boost event and configured to adjust at least two of compressed air injection rate, duration and timing of at least two air injection pulses within said pneumatic boost event, the method comprising the acts of: initiating the current pneumatic boost event to inject compressed air into the engine; monitoring at least one operating parameter of the vehicle; determining whether the at least one operating parameter is within a predetermined range; adjusting, based the determination of whether the at least one operating parameter is within the predetermined range, at least one of the compressed air injection rate, injection duration and injection timing to maintain the at least one operating parameter within the predetermined range; comparing a response of the at least one operating parameter of the vehicle during the current pneumatic boost event with a response of the at least one operating parameter during a previous pneumatic boost event; and determining whether a difference between the response of the at least one operating parameter during the current pneumatic boost event and the response monitored during the previous pneumatic boost event exceeds a predetermined difference indicative of having reached an operational limit of a component of the vehicle.
