3D model of the AT IC motor 1 (gasoline version) shown in 4 setups. This motor is designed specifically for running on 2++ generation biofuels. The upper 2 models show 2 setups with only an internal combustion motor (one running on 2nd generation bioalcohols -ie bioethanol, biomethanol or biobutanol- the other running on bioethanol or nitrous oxide). The lower 2 models show 2 setups with both an internal combustion and a (alpha-type) stirling motor. The efficiency of the first two are about 30%, the lower two have a 70% efficiency. Due to the large size however of the lower 2 (Beta-stirling motors are smaller) are mostly intented for stationary use, ie to generate electricity using alternators, … The models with motors that can run on 2 fuels (ethanol/nitrous oxide), do so using seperate lines (the fuels are not mixed). Due to the high temperature required to ignite nitrous oxide, the motor is switched to nitrous oxide once the motor is sufficiently hot (from first running on ethanol).
