Hi,
now don't shoot me, but i got a strange question: would it theoretically work, to inject water into the exhaust manifold, to spool big turbos? the injected water would become steam and thus expand rapidly. that would be a kind of antilag, or am i missing something? i said theoretically, because you obviously would have to work out something special, since you can't just screw in a water nozzle in a super hot manifold and expect it to work. but what about the idea itself?

kinda how a train works? hmm i wonder if water expands enough to matter?
|
Any water that ended up in the combustion chamber would **** up the process because water doesn't compress in any state. Therefore you would have to be able to purge all of the water somehow.
|
He ment into the exhaust manifold. It would not go back into the combustion chamber
|
i think the sudden drop of temperature will greatly slow down the exhaust air because warm air moves faster , and also, it will make the exhaust gas more dense, so whatever expansion the water will make will make the exhaust more dense.... i could be wrong though
|
It would certainly make it blow a lot of smoke, or steam rather.

When you inject water into the exhaust it will boil and increase the manifold pressure and decrease the exhaust gas temp. This will allow the turbine to extract more work, however the increase in manifold pressure will also mean increased backpressure on the engine.
This will make for an interesting thermo problem. What is the typical flow rate and pressure through the manifold? |
Neat idea, but repeatedly spraying cool water into an exhaust manifold will cause it to crack.
|
i had a thought about this too, but my ideal was to shot Nitrous Oxide at an angle from the manifold to the turbine to serve as a pre-spool
