Is water injection effective on turbo diesels?
Yes, Water injection can improve the torque output of the diesel engine, simply due to extra cylinder pressure during the evaporation of water. Further information links can be found on the “design/reference” section on this site. 21. Do you have any practical example of a water injected vehicle ? Not exactly, the only example we have encountered was a 11.5 litre, boost pressure of 4.6 bars (absolute) !!! The Skoda truck was run by a very dedicated team from Czech Republic, and they are currently running the European truck Championship.
