I know Nos injection works but how about water injection seen it in magazines ?

Question

How do,s that work is it anything 2 do with hydrogen gas ?

Answer 1

Water injection is not direct into the interior of the cylinders, but a cooling spray used to reduce temperature in the manifold and other high temperature areas. This means the engine can operate for longer periods at higher revs, slightly increasing the horsepower.

It also has a similar effect to an intercooler, by reducing the ambient temperature, the fuel/air mixture (or vapour in the case of injected engines) takes up less volume by weight, and therefore more fuel and air (in terms of mass) can be forced into the cylinder, again increasing explosive power and therefore bhp.

As this forms part of an external cooling unit, it (as far as I am aware) does not impact insurance costs, but you may have to declare it as an enhancement.

Only realy has a marked effect (>2%) on top of the range cars, and engines which run VERY hot (track racers etc) and needs maintenance. Nos is still the way forward if you want cheap power!

G'luck

Answer 2

I agree with chris M, you can use lower octane fuel too. Jules, auto tech and lecturer. Australia.
