Technology Features and Development Methods for Spark Ignited Powertrain to Meet 2020 CO2 Emission Targets

For achieving the forthcoming CO2 emission targets of 95g/km by 2020 and for the years beyond, comprehensive activities for powertrain technology as well as development methodology has to be utilized. It will by far not be enough to add a few single technology features to achieve the desired result. More and more the success will result from comprehensive combining of synergetic utilization of complementary effects. This will be the powertrain perfectly matched to the vehicle, including the energy source, and all together integrated by means of advanced development tools and methodology.

Shorter Engine Development Periods through Modern Fuel Consumption Measuring Technique

New combustion principle concepts combined with enormous application efforts as well as rapid development of gasoline- and diesel injection systems, make high demands on the fuel consumption measuring system. Because of the high degree of automated test bed applications, challenging requirements to reliability and plausibility of measuring results at simultaneously shorter measuring times arise. The following paper describes a new fuel consumption measuring system by presenting specific application examples and shows how efficient utilisation of resources, regarding manpower and test bed capacity, can be reached and how a significant timesaving can be realised.
