valuation calculations of the autonomy of an air car: vehicle use CAT technology (MDI compressed air engine)Adeline Fabre and supervised by Jacky Mochel Benouali J and R. El Chammas October 2003

This study has set itself the object evaluating energy performance engine with compressed air designed by the company MDI; then we could deduce an approximation of the autonomy of the CAT vehicle using this technology.

Based on the current pattern of engine operation, achieving a relaxation of the tiered air, Air Expansion software developed by the Energy Center of the Ecole des Mines de Paris, was the support of all the simulations.

At first we considered air as an ideal gas and conducted simulations for different engine operating speeds. Then we defined a class size of three-story displacements, optimizing the driving range at constant speed.

The dynamic simulation, after the addition to the simulation model, of the characteristics of an urban cycle as defined in the regulations, made it possible to evaluate the autonomy of the vehicle under "real" operating conditions.

In addition to the vehicle speed, it was shown that the ambient temperature was also a strong impact on the driving range. That is why we have added to the simulation model a burner system for heating the air at the entrance to each floor, and this more than just exchangers.
