Patent number: 8805606Abstract: An apparatus and method for improving vehicle performance by application of pneumatic boost to vehicle engines, including diesel engines having at least one turbocharger supplying air to the engine, in a manner which increases engine torque output while minimizing the potential for exceed various operating limits to the maximum practicable extent. The vehicle's pneumatic booster system controller implements strategies for shaping the rate of the air injection during a boost event, tailoring the air injection to obtain maximum engine torque output while respecting the operating limits, by controlling the timing, duration, quantity and/or injection pattern during a boost event to achieve a refined distribution of compressed air injection over the course of the boost event to provide desired engine torque output and fuel efficiency while minimizing the potential for exceeding a wide variety of operation limits, regulatory, engineering and passenger comfort limits.Type: GrantFiled: May 19, 2010Date of Patent: August 12, 2014Assignee: Bendix Commercial Vehicle Systems LLCInventors: William J. Schaffeld, Nicholas Asmis, Mark W. McCollough, Richard Beyer

Publication number: 20140158099Abstract: A system and method for improving exhaust gas recirculation performance is provided to induce improved exhaust gas recirculation flow during engine operating transients, including transients in which exhaust gas flow conditions are unfavorable. The apparatus includes an exhaust line including a mechatronic exhaust brake valve, an intake system including a PBS compressed air injection system, an exhaust gas recirculation passage between the exhaust and intake lines, and a controller which coordinates operation of the PBS and MEB. The controller is programmed to command the MEB to close for a period before the compressed air injection is initiated so as to build exhaust line backpressure pressure and maintain a desired pressure differential across the EGR passage so that recirculated exhaust gas flow continues to enter the intake during to PBS injection event to suppress formation of undesired excess NOx, particulate and other emissions.Type: ApplicationFiled: December 10, 2012Publication date: June 12, 2014Applicant: Bendix Commercial Vehicle Systems LLCInventors: Nicholas A.
