Summary

The ultimate goal of current powertrain development efforts is to achieve power, fuel consumption and emissions targets by applying cost effective processes and tools. Due to the increasing number of variables, a simulation of the entire system is required in order to evaluate the global optimum and the potential of the individual subsystems entailed. A proper base engine design can be a comparably cost effective way to reduce fuel consumption. A future oriented design approach allows for engine weight optimization and thermal management while simultaneously reducing engine friction. Furthermore, the thermodynamic potential in the areas of valve train, boosting and combustion has to be utilized such that besides low fleet emissions for new vehicles the customer benefits in terms of attractive vehicle cost and low in-use fuel consumption.
