22nd Supercharging Conference 2017
The 22nd SUPERCHARGING CONFERENCE in Dresden provides on September 28th / 29th 2017 in Dresden a forum to experts from all over the world, where the latest developments in supercharger techniques are presented by OEMs and suppliers.
The aim of the supercharging was the increase of the brake mean effective pressure. The engine power increase had to prove a significant reduction of the specific fuel consumption. In order to improve the delayed boost pressure while the high load demand increases, new solutions have been developed. Especially with regard to vehicle engines, nowadays downsizing (less cylinder, lower total displacement) makes a high demand on the dynamic behavior. Solutions are: smaller exhaust gas turbochargers, the variable turbine geometry or sequential turbocharging as well as multi-stage charging. In addition to these thermodynamic systems, other sources of energy have been used in order to make boost pressure temporarily available: kinetic energy with the help of a mechanical charge or electrical energy with the help of an additional electric charge. The exhaust gas recirculation provides an important contribution to reduce the NOx-emission. In addition to the recirculated exhaust gas the engine needs to be supplied with enough fresh air. Thus, a significant increase of the boost pressure is required. Studies on Real Driving Emission (RDE) show that high dynamic load demands increase the NOx and particle emission, supercharging can reduce them.
The optimization of the supercharging for internal combustion engines requires a precise knowledge of the whole system’s behavior. Simulation models help to predict the operational behavior very well. The 3D calculation is an important tool for the optimization of air and exhaust path. Nowadays the control of these systems is also done by real-time models. At the high dynamic engine test bench the whole system is tested and the model-based control is optimized by additional structures.
The 22nd SUPERCHARGING CONFERENCE on September 28h / 29th 2017 in Dresden focuses on recent results and development methods. Speakers will be engine developing engineers, manufacturers of supercharging systems and of other important components. The engines that will be discussed at the conference offer a wide range, from car engines up to the slow-speed two-stroke marine engine. The conference will be held in German and English supported by simultaneous translation.
This conference offers an excellent exchange of knowledge and experience for everyone working on the development of supercharged internal combustion engines.
