4. VDE Propulsion is composed by two units:
1. Compressor Unit
2. Expander Unit
• Variation of the displacement
• Variation of the compression ratio
• Variation of the phase of the intake/exhaust port in respect of the TDC/BDC

VDE Propulsion: the Patent
International extension N° PCT/IB2015/057610 of 10- 05-2015
14. Forecast by the European
Association including ALL
Automotive representatives:
- Development of electric systems
expected slow
- Use of conventional and bio-fuels
expected very large still in 2050
Note: VDE Propulsion technology can use
any fuel in the same engine
15. VDE Propulsion: expected results
• Dramatic reduction of pollutants especially NOx
• Reduction of the engine weight parts up to –
70%
• Reduction of vibrations up to – 95%
• Noise reduction (possibly values below 50db)
16. VDE Propulsion: expected results
of the rpm
• Higher thermal efficiency average from 18% of traditional
engines to 30-35% of VDE Propulsion
• Greater concentration of power from current 1/0.9 to 1/0.22
• Greater torque constancy from current 30% to 90% of the rpm
17. Braking Energy Recovery when absorbed power is
higher than power output
VDE Propulsion: expected results
18. • Multi fuel mode (the engine can use all types of fuel)
• Simplicity and extreme functionality of the function
Start & Stop
VDE Propulsion: expected results
