Relatively vague/unimportant question
1. at what temperatures in the cylinder (or exhaust gas) does nitrogen start to break down into nitrous oxides at an environmentally harmful level?
More important/actually would like to know question
2. what is the average level of NOx ppm at 1600 degrees F of exhaust gas temperature?
i've been wanting to talk to combustion engineers to get this answer to then see if creating an affordable nitrous oxide sensor would be beneficial or redundant for tuning....with the intention of warning the user if they're reaching a level where knocking/pre-detonation is more likely to occur.
then establish whether it's redundant or more effective than just measuring egt's alone or if it's a waste since it's measuring a by product of egt's essentially....
basically just brain storming whether or not this sensor could be more or less useful/accurate than just an egt guage since instead of just measuring the heat and not knowing the chemical composition, it can measure the chemical composition similar to a wide band a/f guage, thus possibly being a useful tool for tuning....or a redundant waste of time and money
