Stuttgart, Germany, Jun 25, 2008 - Computer simulations and the visualisation of injection and combustion are providing detailed insights into the combustion process in the automotive engine. To control, regulate and monitor the engine online, Daimler AG makes use of electronic control units. The researchers and the advanced and series development engineers are working toward optimising these instruments and the software they use by means of novel control methods.
Optimal engine power, with minimal fuel consumption and exhaust emissions: these are the conflicting aims facing Daimler's engine experts. At the same time, they must be thoroughly familiar with the electronic control units and the accompanying complex software. And with each new technology or specification introduced, such as an emissions directive, the number of functions and volume of data stored in the control unit drastically rises. Each modification influences all existing software components.
Algorithms for new combustion processes and exhaust gas aftertreatment are thus a key focus of development. The aim is to directly influence the combustion process in the cylinder through model-based engine management control. Engine output is also to be increased, smooth running optimised and emission levels reduced even further.
