In this paper, methods for performance characterization testing of Dual Mass Flywheel system (DMF) are presented. The DMF system is used to reduce the torsional vibration and noise occurring in automotive powertrain. It isolates rotational irregularities largely from engine rotational fluctuation. To measure the performance characteristics of DMF, real vehicle testing modes are investigated and measuring equipments are installed in three types of powertrain of a vehicle.<br/> The performance characterization testing of three systems are performed and compared to each other. And the investigated testing methods will be used to test the performance of DMF systems.<br/>

This study include about emission and fuel economy characteristics of the Lupo 3L TDI is the<br/> world's first-ever production-line unit inj ector type 3 liter car. On the results of test, the fuel<br/> economy was below then of volkswagen's reports. But that was very considerable because to<br/> consider the research trend of the vehicle makers, most of all research is focused to reduce<br/> the CO2 and high performance than another advanced vehicle. In case of emission, the test<br/> results was be satisfied with the EURO3 regulation but to be unreliable the EURO4.

The Lupo 3L TDI model is the world's first-ever production line 3 liter, a milestone of energy<br/> conservation in automobile engineering was tested and benchmarked. this model is high fuel<br/> economy performance in terms of 3liter car level of diesel fueled engine producted in the<br/> world. Some several items were tested compared with korean products. in this paper, the<br/> benchmarking test results are included and described the characteristics of Vehicle components.

The accelerated testing technique using the equivalent load condition plays an important part in the automotive industry. However, the theoretical background and advantages of this technique have been on the rise recently. The environmental durability condition forms the foundation of the accelerated testing technique, so it is important to analyze the loading components and damage in service environment. We developed the GUI program for the determination of the accelerated testing condition under the multi-axial loading, and introduce the theoretical background and process for application of the program.
