Summary:

This paper describes the results of an investigation into alternative control strategies for diesel engines equipped with Exhaust Gas Recirculation (EGR) and Variable Geometry Turbocharging (VGT). The objectives of the research were to improve the engine aircharge performance during transient manoeuvres, thus bringing benefits for fuel economy, exhaust emissions and engine transient performance. Two of the investigated areas are detailed in this paper;A simple and effective method for coordinating the EGR-VGT system is demonstrated to improve airflow response to tip-ins and tip-outs. The exhaust pressure feedback method is shown to overcome difficulties in the transient control of VGT systems, offering improved engine torque response and reduced transient backpressure
