I was always under the impression that the performance advantage of water-injection systems for diesel vehicles were:
1. It reduces exhaust gas temperatures, thus allowing the engine to be used at its highest level of power with reduced risk of heat damage.
2. When methanol is added to the water, the engine can realize some enhanced power along with fuel mileage as a result of burning the methanol as a fuel. However, the cost of methanol can negate the fuel mileage enhancement.
Water itself has no calories to burn, but some say the water can turn into energy by converting into steam in the cylinders. I question how much energy actually can be realized this way inside a fuel-burning diesel engine.
I considered a water-injection system for a diesel truck that has no intercooler in order to control EGTs, but gave up the idea for various reasons.
