Study of Handling Behavior of a Passenger Vehicle after addition of CNG Tank

Objective The objective of this paper is to achieve a comparable handling performance from a vehicle fitted with a CNG tank to that of its gasoline counterpart. A validated CarSim model is run through standard handling evaluation tests before and after the addition of CNG tank. The simulation results are used to compare the handling characteristics of the CNG vehicle with the Base vehicle. Further these results are used to tune the suspension parameters to find an optimum set-up for the actual CNG vehicle. The final parameters are then evaluated in the actual vehicle to verify the study. Methodology A mix of Actual Mule vehicle testing backed by quik Car Sim Model. Full car model is first developed using CarSim by using the parameters of the actual base gasoline vehicle. The modeled vehicle is then tested for standard handling maneuvers such Double Lane Change, Constant Radius Constant Speed and Pulse Input.
