Long-duration sparks

Nitric oxide is the most stable oxide of nitrogen. It decomps above 1000° and will not support combustion below this temp. When mixed with hydrogen, it can be expld by a long duration, intense electric spark (Ref 8). It is very endothermic, its Qf being —21,575cal/g at RT (Ref 5)... 

Remember, the objective is thus to create the longest reasonable spark arc duration in order to maximize the electron flow for the plasma cold fog reaction, but not so long as to melt the plug electrodes. Obviously, Sir s timing Is within reasonable limits, though it may not be optimized for maximum performance.
