I believe the outcome would in effect,be like lowering the displacement of the engine,with loss of power,efficiency,mpg,with all the original canibalistic internal losses.------------- The CO2 is already fully oxidized,will act as an inert gas,displacing valuable oxygen,reduce the charge density,lower BSFC.----------------- Beside all that,how could you possibly hope to monitor and adjust" stoiciometric" ratios.---------------- Co2 is used in fire extinguishers,and plenty believe we already have plenty in the atmosphere.-------------------------- I think you should look elsewhere for a solution to driveability issues.
