Abstract
A system for achieving temporary increase in performance in a turbo-charged combustion engine comprises a microprocessor in which there are stored a value of the maximum permissible charge pressure at constant load and a higher value of the maximum permissible charge pressure at increasing load. The processor senses the charge pressure and is connected to means which sense the rate of opening of the throttle. At a certain rate of opening, the processor permits an increase in the charge pressure to the higher pressure and thereafter effects timed reduction of the charge pressure to the maximum permissible pressure at constant load.
