Kinda!

Obviously, this is a completely unworkable delivery method of getting CO2 into the cylinders to begin with.

But engines actually use their own exhaust (which is mostly water and CO2 in nitrogen) to displace some air/fuel by just sucking exhaust back into the cylinder (exhaust gas recirculation or EGR). This alters the thermodynamics of combustion and can reduce nitrogen oxides formation, and reduce power loss due to throttle pressure drop, among other benefits.
