I guess they add more fuel with dry too, it is just increased open time of injectors that gives extra fuel. Then it's game of, "are my injectors big enough".
Yeah, those 2 replies are correct. You can map a dry system with stock injector or injector position to provide more fuel, and AFAIK if you use a wet system ive read some people just remove the older injectors and use them instead. Basically there is no logic as to why one should provide more power than the other, and there is no example of doing that. Its just that wet systems are slightly more complex to install.
No, the way you do that is to make a tube that sprays fuel on the exhaust tips. When the gas hits the hot exhaust, the fuel vaporizes, then combusts.
It's mostly a drag racers' thing, but there are drag cars in the game, so... Any decent implementation would also include size of shot as a tuning option, along with the possibility of fragging your engine if it's set too high.
In some regards wet is easier. Adding an extra injector isn't complex but not everyone knows how to retune efi accordingly and you don't have the choice at all on a carb. Just throwing an injector that's pumping X amount of extra fuel ain't so bad if you assume open throttle conditions. It is more dangerous though.
Yea which has nothing to do with a N2O injection... Interestingly most german things talking about the matter actually consider the "dry" version without the use of additional fuel, the Americans on the other hand do what was posted above (location of additional fuel injection).
Just about everything in UK talks of dry requiring ECU remap to be aware that it needs to inject additional fuel. Hence systems like the haltech and omex aftermarket ECUs specifically advertising n2o switch support
But wouldn't you lean out without adding extra fuel at all? I mean if you add only oxygen to cylinder, you practically lean air:fuel mixture. Maybe with small amounts ECU can correct situation, but adjustment window usually is quite small.
I think the idea is to not even reach the temperatures needed to break up the N2O, so it doesn't act as additional oxygen. It's only used to cool down the intake air...
If nitrous oxide doesn't make your hot hatch spit flames, then where did that originate? Probably offtopic but just wondering.
As far as I know, there are two different injection methods for N2O. - Single port (fog plate). Usually one nitrous injector somewhere in the intake tube coming from air filter to throttle body. - Direct port. Uses a nitrous injector for each fuel injector on the fuel rail. (injects n20 in the air intake manifold, above intake valve) Both types can be wet or dry setups, as stated above. The fogger type is prone to uneven distribution to cylinders, which is why direct port is generally safer - especially for larger amounts of n2o injection. If you look at it as 'simple' combustion - you have heat, fuel, and oxygen. The nitrous oxide hyper-oxygenates the combustion process, making it burn faster and hotter. (like oxyacetylene torch) When this is done under the pressure of the cylinders, it become a more powerful explosion. You don't really have to worry about it leaning out from nitrous, because the fuel is still there, and it's not really altering the air/fuel mixture much, but rather making the combustion process that normally takes place, happen with more energy. What you do a have to worry about, is creating too much energy from the combustion process, that the mechanical limits of the engine are exceeded. === Flame throwing exhaust I always thought was done by running a rich fuel mixture, and welding spark plugs into the exhaust pipes, triggered by a switch or button. Speaking of that though (sorry this is turning into long boring post)... I am guessing it's theoretically possible to make make flame, smoke, and steam 'shooter' in BeamNG? Like a way to position a particle effects emitter that is triggered by button? Is that possible? I really want to add purge function for N2O...
Same place where regenerating N2O tanks originated from, video game fantasies Although having said that, in theory a wet shot of nitrous could cause backfiring if the engine is tuned to run rich (unburned fuel will pass through the exhaust at combustion temperature, but the lack of oxygen will make it so that the fuel only ignites upon exiting the exhaust, causing backfiring/flames) but I'm not sure.
I don't know, this sounds bit odd to me. Purpose of cooling air is to get more air (oxygen) to engine (you have certain space and you want maximum amount of air/oxygen to that space). To make more power it does not help to add the air, you have to add more fuel too, 8-12:1 air:fuel ratio for maximum power, depending from many variables, 14.7:1 is nice compromise and leaner you go, less fuel consumption you will have, but not very easy to do without engine damage at WOT. Then again it is probably quite unimportant in game wise, one just have to have a button that makes engine power to multiply for defined time, well maybe blowing engine might be nice possibility, important is thrill which risk creates, everything else is quite secondary.
In BeamNG if you increase the power too much, it melts the engine... literally. It would not be hard to have it randomly increase too much... that's a good thought actually... I think I can do that.
Ah no, the engine detects the cooler (denser) air by itself via the mass airflow sensor, so it will inject more fuel for the more dense intake air anyway.
You know the BeamNG devs; they'll want to do it right. The turbo simulation isn't quite perfect (and would apparently be more trouble than it's worth to make perfect, even if the payoff would be independently damageable turbos on multi-turbo setups), but how well they did it, and the fact that they actually bothered with supercharger simulation where most games (even Gran Turismo, and in GT6 you can verify this by installing a boost gauge on an SC car; it will just sit at 0 the entire time you're driving) just treat supercharged engines as if they were NA, indicates that they might not be satisfied with just a timed power multiplier. If they were going to make it official, they'd almost certainly try to make it as realistic as possible with adjustable shot size, varying bottle pressure (possibly along with availability of nitrogen-assisted setups to increase consistency), and, of course, possibility of engine demolition from excessive mechanical stress, a poor setup, or bad driving (there's a video somewhere on YouTube of a guy in a CRX who suffered an engine fire and turned his intake tube into a projectile weapon because he tried to launch while purging or something).
