Scientific analyzes and evaluations on MDI Air Engine by J. Benouali, D. Clodic from the Ecole des Mines de Paris, July 2003.
The concept of MDI CAT is based on different ideas:
- a compressed air motor
- reversibility of the motor that can be used as an air compressor (braking)
- a light urban vehicle
- small-scale vehicle manufacturing (micro factories) to limit delivery costs
This study is based on figures provided by MDI. The current design of the MDI engine named 34p01-4 is a 3 stage air expansion design with 2 intermediate heat exchangers to heat the air between 2 expansions.
