And water adds 1kg per ltr to start weight. (But! burning a ltr of fuel produces well over a ltr of water, so can it be recovered?)PlatinumZealot wrote: ↑Sun Aug 19, 2018 12:37 amSteam injection?NL_Fer wrote: ↑Thu Jul 26, 2018 10:27 pmWith a sharp limit on oil consumption, the tech-heads must be looking for other ways of adding some to the combustion. How about coolant? What is possible to add in the fluid and what could be gained?
Even if a combustable additive is not possible, how about preventing knock or even just cool the charge temperature. Any ideas if such is possible or why not.
It could add power but you need a whole lotta water to last a race. The fuel injectors are 300 to 500bar.. But no need for the water injector to be that high since it will be injectected after peak cylinder pressure. So you would set up a water pump that can do say 200 bar than a heater to heat the water to about 370 Degrees Celcius. Upon Injection into the cylinder whose pressure will have fallen to less than 200 bar, the water will expand into steam and push the piston down.
You are basically putting a steam engine into the PU.
The problem is do you have enough water for this? And where do you get the heat to go to 370*C? The brakes? Electric heater? The exhaust pipe?
