RE:RE:NHHH Fault seekers are swarming again.I agree. I have asked about what happens to the nitrofen forming NO, maybe not NO2. At that combustion temperature I am suspicous that no NOx is formed. California has a 4 ppm limit on NOx for gas turbines, and steam injection is used to bring down the temperature, but in a auto ICE this is not feasible. Maybe on a huge diesel.
