COMPRESSED AIR ENGINE

2 COMPRESSED AIR ENGINES

MDI have created 2 compressed air engines which is the base of Automotive and Energy applications.

Small 7 kW Engine @ 1,500 rpm, 45 NM, 430 c.c.

The engines can be grouped together (‘banked’) so, by way of example for electricity production, if 8 engines were banked with each engine providing 7 kW of electricity the total electricity provided would be 56 kW.
 

 

Larger 72 kW Engine @ 3,000 rpm, 230 NM, 1,000 c.c

The engines can be grouped together (‘banked’) so, by way of example for electricity production, if 8 of the larger engines banked together would provide over 500 kW of electricity.

ENGINE

Simple & Efficient

Based on the new MDI thermodynamic cycle.

The primary energy is made outside the engine, and this gives much greater efficiency than the internal combustion engine.

Overall energy efficiency more than twice that of internal combustion engines and
capable of reaching over 70%.

There is no internal combustion. That alone brings down the noise.

The engine itself needs very little maintenance at all. Just 1 litre of vegetable oil every 50,000km.

Efficient, clean and clean external combustion, multi-fuel capable, enables
competitive use of biomass fuels and direct thermal solar.

 


 

TORQUE

ADVANTAGES

  • Compressed Air Engine has a flat torque curve.

  • Expansion of the compressed air lowers its temperature; this may be exploited for use as air conditioning.

  • Compressed air engines reduce the cost of vehicle production, because there is no need to build a cooling system, spark plugs, starter motor.

  • Some mechanical configurations may allow energy recovery during braking by compressing and storing air.
  • Enables impressive cost reductions for manufacture, operation and maintenance of low cost, zero emission vehicles and environmentally sound distributed power generation.

  • Automatic door locking yes, no keys just an access card that can be read by the car from your pocket.

  • The company is able to offer very competitive prices by eliminating many of the traditional industry costs. They sell direct to customers with no dealers, no showrooms, no advertising, no brochures and no 'car salesmen'.
