HxCy + O2 --> Heat + H2O + CO2
where HxCy is some hydrocarbon fuel. Just like carbon dioxide, water is a natural byproduct of "perfect" combustion. (Balancing the equation requires first defining what fuel is being burned.)
The product of a hydrocarbon combustion is co2 and water. The heating value realized is higher, so the phase state of the fluid is liquid due to exhaust pipe cooling.
too expensive to practically process the water for each vehicle, even though idea is novel. nothing violates the 1st law, so processing the water will cost an additional input of energy - fuel. either to actually do it, or to make the parts to do it.

Proper Chemical Reaction in Cylinder gives water as by product with other burned product and unburned products.
Moisture in air can increase the water in exhaust and decrease the power output.
Believe it or not, some water injection in the cylinders can actually increase power output, by helping to delay pre-detonation. This permits the use of higher compression ratios or of higher supercharger or turbocharger pressure, for any given octane rating..
