Patent ID: 8666634

Claim:
A system for increasing vehicle performance using pneumatic boosting, comprising: an engine having an intake, an exhaust and an exhaust gas recirculation passage for recirculation of a portion of exhaust gases from the engine from the exhaust to the intake; means for controlling air flow located in the intake, the air flow controlling means including an intake block-off element located in an intake, at least one compressed air injection passage open to the intake on an engine side of the intake block-off element, and a passage open to the through which exhaust gases passing through the exhaust gas recirculation passage are introduced into the intake; a compressed air source arranged to provide compressed air flow to the air control device; means for controlling pneumatic booster injection, wherein the pneumatic booster controller means controls a pneumatic boost event based on at least one monitored operating parameter of the vehicle by coordinating compressed air flow through the compressed air injection passage and the intake block-off element to supply compressed air to the engine via the intake, the pneumatic booster controller means controls the compressed air flow through the compressed air injection passage to provide the compressed air injection by adjusting at least two of compressed air injection rate, duration and timing of at least two air injection pulses during said pneumatic boost event so as to maintain the at least one monitored operating parameter of the vehicle within a predetermined range; and means for controlling an engine which controls fuel injection into the engine, wherein the means for controlling the engine controls injection of additional fuel into the engine upon learning of an impending and an actual pneumatic boost event, such that additional fuel corresponding to an impending or actual compressed air injection pattern associated with the impending or actual compressed air injection pattern is injected during the pneumatic boost event.
