Preface

In the field of creation, manufacturing and testing of modern automobiles are mani￾fested demands and requirements, sometimes contradictory, related to: security, aero￾dynamics, design, energy efficiency, comfort, noise, vibrations, entertainment, respect

for the environment, reliability, preservation of resources, technological optimization,

costs and recycling. The automotive industry is characterized, on the other hand, by a

strong competition in inventiveness and high technology products. Rapid and large￾scale evolution is dependent on the capacity of the research and design departments

of the manufacturing companies to assimilate and work with innovative engineering

methods. Numeric simulation represents one of the effective environment that support

the activities related to:

– New materials engineering

– Product–process interdependency

– Development of future automotive concepts: hybrids, autonomous and

interconnected

– Virtual reality: simulation, optimization of process management

– Topological and technological optimization

– Cost efficiency of research and development.

Introduction of RDE (Real Driving Emissions) measure starting from September

2017 for Euro 6c (new models) and Euro 7 (starting with January 2020) is a new

challenge for large automotive manufacturers. The advancement in internal combustion

engines and electronic systems used in control and analysis constitutes guaranties for

future solutions for treating and filtering the noxious and particulate emissions.

To respond to the major challenges faced by the automotive world, the authors

of the papers presented in the technical sections of CONAT 2016 International Con￾gress offer their vision and solutions in the following areas:

– Advanced Engineering Methods

– Innovative Solution for Motor Vehicles

– Heavy and Special Vehicles

– Automobile and Environment

– New Materials, Manufacturing Technologies and Logistics

– Advanced Transport Systems and Road Traffic

– Accident Research and Analysis.

The presented papers were selected from 222 proposals submitted. All papers were

developed by 218 specialists from 14 countries. Assessment and systematization of

presentations were performed by an international scientific committee. They were

analyzed for the novelty and scientific content, as well as for the layout of each paper,

following the requirements imposed by FISITA, SIAR, SAE International and Springer

Publishing.

The initiation, implementation and completion of activities for preparing, collecting

and finalizing of the volume containing the Proceedings of CONAT 2016 Congress

were possible, thanks to the involvement and professionalism of Dr. Dinu Covaciu, the

Coordinator of the Technical Programme of Congress. We thank him for all his efforts.

We also express our gratitude to our colleagues from Transilvania University, and to

the members of the scientific committee and reviewers, to organizers and partners from

the companies Schaeffler, Renault Romania, Atlassib, Horiba, AVL, Tedata and

Brahms, for their support and involvement in all activities of organization of the XIIth

edition of the International Congress of Automotive and Transport Engineering

CONAT 2016.
