Overview

Background & Policy context

Future European HD diesel engine technology is facing extremely low exhaust emission standards (EURO IV) combined with a new engine test procedure (European Transient Cycle ETC) as well as increased customer demands with regard to high engine performance, improved efficiency and reliability. Therefore appropriate technologies such as exhaust gas recirculation (EGR), variable nozzle turbine turbocharger (VNT) and exhaust gas after-treatment systems have to be applied to future HD diesel engines. Especially high-precision control of EGR in combination with a VNT-turbocharger
requires new engine control strategies.

Objectives

The objective of the proposed project was a research program focusing on a new advanced truck engine control system ATECS to reduce application effort and improve engine control within transient operation. Furthermore a new approach towards ECU control algorithms with uncoupling control of EGR and VNT was to be applied and tested within the new European Transient Test cycle (ETC).

Methodology

Two state-of-the-art EURO III truck diesel engines (7l and 12l) were equipped with EGR systems and VNT turbochargers. With the modified engines steady-state and transient investigations were carried out on the test bench. From these results a realistic simulation model, as needed for the controller design, has been generated. For the development of the model component measurements of the actuators, the turbocharger and detailed thermodynamic calculations were required. Finally the truck engine model included the four components of engine, VNT turbine, compressor and EGR system, and allowed the simulation of real engine transient behaviour, for investigation of an uncoupling truck engine control system for EGR and VNT. After improvement of the Advanced Truck Engine Control System and transfer from the investigation platform to an engine control platform the application work of the prototype engines within the European Transient Cycle ETC was carried out.

Results

The S&T workplan for this project contained the investigations of two Diesel engines (7l bus engine and 12l HD engine) equipped with EGR and VNT systems including steady-state and transient measurements and in parallel the research of an engine simulation model with advanced control strategies for EGR and VNT. After improvement and validation of the simulation model the new control strategies were transfered to the prototype engines. Afterwards the application work for the prototype engines within the European transient cycle ETC was carried out with close response to the simulation model for additional improvements. The main project output was advanced truck engine control strategies with uncoupling control of EGR and VNT as well as ETC exhaust emissions and fuel consumption results from two different truck engines.

All Project targets were attained.
