ok
so 2 stroke engines do not normally get water injection on the intake side. Water is often injected on the exhaust side to change the temperature of the exhaust gas, and thus changing the tuning of the exhaust chamber, alot like playing with the valve timing of an engine, this lets you shift peak torque around.
BUT i want to inject water on the intake side.
Most jetski engines are designed with intake systems to prevent injestion of water. Generally when water is injested by the engine, it is often highly uncontrolled and often at much greater then safe amounts. When this happens it often causes piston seizures. I beleive this is due to gross and uncontrolled amounts of water causing rapid localized piston cooling. yes no?
NOTE: nothing happens to the crank system. I beleive this is due to the operating temps of the lower end and the fact most 2 stroke marine oils are highly water resistant and the crank is entirely supported by needle and ball bearings.
What i want to do is safely inject water into the intake side of the engine, for its obviously well known benefits.
Can anyone chime in here with technical reasons or ideas why this would not work? Ideas on the seizures?
I also beleive this is why these engines enjoy gross overfueling as the extra fuel is utilized for combustion cooling as in the case of turbo engines without proper intercooling/water injection.
NOTE: i want to use PURE water injection, this is for a jetski so i would have a virtually unlimited amount of available water. no methanol or other additives please.
anyone's help or experience would be welcomed
sorry for any spelling mistakes or whatnot, im watching futurama at the same time as writing this
