With the emission standard shift from BS4 to BS6, numerous development and validation activities need to be carried out to achieve the necessary emission targets within a very short time. The conventional iterative development approach, irrespective of any work package at the engine/vehicle level, requires huge efforts in terms of calibration and validation to meet the emission standards and overcome the challenges specific to the Indian market.

The Diesel Particulate Filter (DPF) to trap soot is state of the art in Diesel engine-powered vehicles and Diesel devices. With the introduction of DPF, robust model-based calibration is required for effective monitoring and removal of soot. The DPF calibration includes work packages such as the soot model, thermal management, soot burning model, and fleet validation. These work packages must be accurately calibrated and validated under all environmental and driving conditions to meet the above targets.

Simulation tools are necessary to create the application efficiently, in a short time, and with high quality. With the introduction of simulation tools, the overall effort and development time required to calibrate each function can be minimized and higher accuracy can be reached. In addition, data visualization also simplifies fleet data analysis.
