Abstract: The presentation discusses the concept of a reciprocating internal combustion engine (ICE) operating with oxy-fuel combustion and patented by CMT-UPV. The ICE is comprising a mixed ionic-electronic conducting (MIEC) membrane that separates the O2 from the air, so that the suction comburent stream is free of N2, and a second Brayton cycle binarily combined with the ICE compression ignitio cycle. The perovskite MIECs have been developed and patented by ITQ (CSIC-UPV) and have been manufactured by the start-up KERIONICS. The ICE cycle transmits thermal energy to the Brayton cycle. The Brayton cycle provides to the ICE air compressed for the MIEC membrane. By means of this engine, the emission of NOx into the atmosphere is avoided by the separation of N2 in the MIEC membrane. The oxy-fuel combustion facilitates the capture and liquefaction of CO2 through compression. In such a way, a negative tank-to-wheel emissions ICE is achieved using conventional fossil -soft blended with bio fuels (B7). This will be possible based in three pillars: 1) It is an oxifuel combustion engine concept; 2) it is able to procure its own O2 supply and 3) it is able to densify and capture its CO2 emissions. 1) allows avoiding NOx emissions and breaking through the NOx/Soot trade off, concentrating combustion strategies in PM abatement. 2) is possible by recovering the exhaust gases energy and using it to separate O2 from N2, with infinite sensibility, in perovskite MIECs. 3) is done using engine mechanical energy to compress CO2 until super-critical conditions (over 70 bar). The project has been economically supported by Valencia local government: Generalitat Valenciana through Agència Valenciana de la Innovació.
