Present and Future of Heavy-Duty Engines Strategies for Compliance to the Emission Legislation
Published September 10, 2002 by CMT in Spain
Due to their high efficiency diesel engines with further increased specific power output will dominate in truck application for the next 15 ... 20 years. Nevertheless the engine technology will change to intelligent and even more flexible components for fuel and air supply, compression ratio and valve timing. With integrated exhaust gas aftertreatment technologies gaseous and PM-emissions will be negligible beyond 2015. Main challenge will be to optimize the interaction of this components using model-based ""closed-loop"" control strategies and the development of low-cost components of this integrated technique with flexible features. Detailed knowledge of combustion and aftertreatment technology for improved modelling will be necessary. Therefore further efforts on basic research are needed though engine technology will not change on principle.
