Sentence examples for decrease in the soot from inspiring English sources

The results of experiment and numerical modeling agree quite well in terms of the levels of soot volume fraction and they both show a decrease in the soot loading as more ethanol is added in the fuel stream.

The Co/CeO2 (0.8) fibre catalysts showed improvements in soot combustion at low temperatures of around 400 °C with 10% O2 and a decrease in the peak soot combustion temperature at about 40 °C was observed with the addition of 500 ppm NO.

For a set of temperatures, computed PAH structures were analysed to determine the functional groups responsible for the decrease in the reactivity of soot with NO with increasing reaction time.

Following World War II, with the transition from coal-based home heating to natural gas and the resulting decrease in internal soot, and the introduction of washable vinyl-based wallpaper, the market for wallpaper cleaning putty decreased substantially.

Electron paramagnetic resonance (EPR) measurements were performed on the soot both before and after supercritical fluid and Soxhlet extraction, and a substantial decrease in the spin density of soot following extraction indicates that extractable molecules are associated with 40 50% of the unpaired electrons in soot.

In the pressure range of 20 to 40 atm both the model and experiment show a diminishing sensitivity of sooting propensity to pressure with a greater decrease in the predicted sensitivity of soot propensity to pressure than the experimental results.

Interestingly, the H/C and the O/C ratios of soot particles increased after thermal treatment, and thus, they do not support the decrease in soot reactivity.

The decrease in soot emission is found to be about 21% at 1,500 rpm and decreases until it reaches 0% at 1,900 rpm.

The gas temperature also decreases due to the large heat capacity of aromatic species considered in the soot formation reaction mechanism.

The addition of oxygen to the mixture promotes soot formation in its early stages by decreasing the soot induction delay time.
