The curve between the critical … Zwolinski and Wilhoit defined, in 1972, "gross" and "net" values for heats of combustion. In the gross definition the products are the most stable compounds, e.g. H 2O(l), Br 2(l), I 2(s) and H 2SO 4(l). In the net definition the products are the gases produced when the compound is burned in an open flame, e.g. H 2O(g), Br 2(g), I 2(g) and SO 2(g). In both definitions the products for C, F, Cl and N are CO 2(g), HF(g), Cl 2(g) and N 2(g), respectively.

Research suggests that LTC has the …

WebEGR dilutes the air-fuel mixture, lowers combustion chamber temperature, and reduces flame speed. When operated at a steady state of about 50 km/h, five percent EGR on a typical engine can reduce NOX emissions by as much as forty percent. Ten percent EGR can reduce NOX emissions about eighty percent. WebOne way to address the pollution problem is to alter combustion so that fewer pollutants are created in the first place. Low-temperature combustion (LTC) is a leading strategy …

WebAs the humidity of the combustion air increases, the temperature of the flame decreases. For example, the temperature of the flame decreases by approximately 2.3% when the humidity increases from 0 to 120 grains. Although the change in flame temperature is small, it can have a significant impact on the thermal NOx production.
