There's a choice of a 1.2-litre 69hp petrol engine, with manual or automatic transmission, or Fiat's 0.9-litre 85hp petrol Twin Air engine
with six-speed manual transmission.
Moreover, the compressed air engine
is considered as a viscous-damping, that is, a relation proportional to the angular velocity of the wheel of the system multiplied by a constant, as given by
The inclusion of a regenerator differentiates the Stirling engine from other closed cycle hot air engine
The new two-cylinder Twin/ Air engine
, the latest development of the TwinAir uses a high-efficiency turbocharger; an exhaust manifold integrated into the cylinder head; a Start&Stop fuel-saving system and a new intake valve control system to provide an even more enticing combination of power and efficiency.
The aircraft has also witnessed mid- air engine
failures, particularly in the last two years.
The system combines a gasoline engine with an air engine
which is used at speeds under 70mph.

Transportation could be the first market with a secured a grant from the Technology Strategy Board, the UK's innovation agency, to build and test a liquid air engine
fitted in a commercial vehicle.
Utilizing more than three times the waveform memory of the previous generation, the AiR engine
provides sensational dynamics, damper resonance and even compensates for the speed at which hammers strike strings at different velocities and key ranges.
The agreement covered two phases of activity encompassing the technology transfer and proof of the technical concept in the first phase, and in the second phase completing detailed development of the compressed air engine
into specific vehicle and stationary applications.
Naturally, there are skeptics who say that the air engine
is far less efficient than claimed.
