Air System Management to Improve a Diesel Engine 2011-01-1829

The paper presents the structure of an air system controller and its application to a modern boosted dual loop EGR Diesel engine. Results over a U.S. FTP cycle which show improvements in emissions and fuel consumption with future opportunities for increased performance are discussed. A recent application of the controller is also shown where standard engine sensors are eliminated to reduce cost and their function is replaced with in-cylinder pressure measurement combined with signal processing techniques.
