Supercharging has always been an appropriate method to enhance performance and to improve the efficiency of internal
combustion engines. Downsizing (less engine displacement - less cylinders) leads to a higher level of supercharging,
the process conduct is improved and a significant increase in efficiency can be achieved. This applies to gasoline
and diesel engines in the same degree and goes along with a higher customer's benefit. Supercharging assists in
complying with CO2-emission standards which means the biggest challenge of engine development, since exhaust emissions
are limited simultaneously with new emission standards.
To observe NOx and particle limitations, high rates of exhaust gas recirculation up to the range of engine full load
are necessary. This increases the level of supercharging further and applies to both high- and low-pressure exhaust
gas recirculation.
The challenge to reach the dynamic engine torque very fast leads to complex solutions, which do not only affect the
charging systems, but also the gas exchange control and other actuating and regulating devices. Model-based control
becomes indispensable to accomplish this challenge.
Supercharged gasoline engines are configured with more cost-efficient packages for emission reduction than diesel engines.
But spark ignition engines fall into the trade-off between increased requirements in terms of exhaust gas temperatures
(1050 °C) and for this reason higher costs for exhaust manifolds and charging units. The new challenge consists in keeping
the heat within the exhaust system and avoiding thermal transfer into bordering components. For this purpose novel materials
and coating technologies are necessary, which have already become accepted on other fields of application.
As a key technology supercharging requires the optimization of the complete system where transient operation definitely
comes to the fore. Today's successfully practised methods of developing are close to process numeric simulation and hardware-in-the-loop
simulation. The complete system then will be tested at the highly dynamic engines test stand.
At the 15th SUPERCHARGING CONFERENCE in September 2010 the most current methods and results of development will
be presented. Engine developing engineers and manufacturers of supercharging systems and other important components
will contribute their part. The diversity of engines will reach from car engines up to slow running two-cycle ship
engines.
Main focus subjects
- New supercharging conceptions
- New supercharged engines
- Components for supercharging (compressors, turbocharger, intercooler, impulse chargers, electrical auxiliary systems)
- Methods of numeric simulation
- Supercharged engines versus exhaust emission limits
- Control strategies
- Performance of the complete system (hardware-in-the-loop simulation)
- Sensor technology, actuator technology, diagnostics and testing
- Methods and tools of development for components and power train
The conference will be held in two languages (German and English) supported by simultaneous translation.
As a specialist conference the 15th SUPERCHARGING CONFERENCE
represents a forum for all those who work for the development of supercharged combustion engines.
More over Dresden as the conference's place is offering quite interesting cultural programmes both during the forum's agenda and during the weekend.
