Diesel exhaust gas contains low molecular aliphatic carbonyl compounds and strongly smelling organic acids, which are known to have an irritant influence on eyes, nose and mucous membranes. Thus, diesel exhaust aftertreatment has to be considered more critically than that of gasoline engines, with respect to the formation of undesired by-products. The results presented here have been carried out as research work sponsored by the German Research Association for Internal Combustion Engines (FVV). The main objective of the three year project was to evaluate the behaviour of current and future catalyst technology on the one hand (oxidation catalyst, CRT system, SCR process), and regulated and certain selected non-regulated exhaust gas emission components and exhaust gas odour on the other hand.

The AUTomotive Open System ARchitecture (AUTOSAR) Development Partnership has published early 2008 the specifications Release 3.0 [1], with a prime focus on the overall architecture, basic software, run time environment, communication stacks and methodology. Heavy developments have taken place in the OEM and supplier community to deliver AUTOSAR loaded cars on the streets starting 2008 [2]. The 2008 achievements have been: Improving the specifications in order to secure the exploitation for body, chassis and powertrain applications Adding major features: safety related functionalities, OBD II and Telematics application interfaces.

Volkswagen has built a simulation model of the EA 111 Motors assembly line. It was an important model to study the plant capacity increasing. The study was made in two phases: 500 motors/day and then 1.200motors/day. Using this model, the company could run different scenarios quickly and identify the bottlenecks in the system. So, they could take better decisions in this capacity planning study avoiding future problems in this assembly line.

Reduction of nitrogen oxides in Diesel exhaust gas is a challenging task. This paper reports results from an extensive study using Pt-based catalysts involving synthetic gas activity testing (SCAT), engine bench testing and tests on passenger cars. Preliminary SCAT work highlighted the importance of Pt-dispersion, and both SCAT and bench engine testing yielded comparable NOx conversions under steady state conditions at high HC:NOx ratios. On passenger cars in the European cycle without secondary fuel injection NOx conversion was lower than obtained in the steady state tests. Better conversion was obtained in the FTP cycle, where secondary injection was employed. Higher HC:NOx, ratios and more favourable temperature conditions which were present in the exhaust contributed to this higher conversion.

The objective of this paper is to explore the influence of freestream turbulence on heat transfer processes to passenger cars in climatic wind tunnels. This will include a consideration of different flow zones on the vehicles. It will be shown up to which value of the turbulence intensity the influence on the heat transfer to the passenger compartment remains insignificant. The effects of freestream turbulence on the design and operation of climatic wind tunnels are discussed. The upper limit for the turbulence intensity can be regarded as a sizing quantity to be used in planning and operating vehicle-climatic wind tunnels in the future.
