“…Therefore, the total heating value calculation formula was expressed as follows:

Q_{Z} = Q_{Y} - 94.1 \times S

where Q Y is the oxygen bomb heating value in J/g, and S is the sulfur content of blends in %. The LHV was calculated as follows:

Q_{D} = Q_{Z} - 225.7 H or Q_{D} = Q_{Z} - 225.7 (0.005 Q_{Y} - 41.4)

where Q D is the LHV in J/g, and H is the hydrogen content of blends in %. The formula for the LHV is stated as follows :

Q_{H L V, m i x} = \frac{\sum V_{i} \times ρ_{i} \times Q_{H L V, i}}{\sum V_{i} \times ρ_{i}} = \frac{V_{g} \times ρ_{g} \times Q_{H L V, g} + V_{b} \times ρ_{b} \times Q_{H L V, b}}{V_{g} \times ρ_{g} + V_{b} \times ρ_{b}}

Blended fuels were obtained with isobutanol contents of 10,20, 30, 40, 50, 60, 70, 80, and 90 vol % with pure gasoline fuel. The physical and chemical properties of isobutanolgasoline blends were investigated using test methods from standards and codes or calculation. No phase separation occurred in isobutanol-gasoline blends at specific temperatures, and isobutanol and gasoline could be blended successfully in every ratio volume. The blended fuel properties were determined, that is, density, low heating value (LHV), 10% volume fraction, kinematic viscosity, stoichiometric air/fuel ratio, octane number, copper corrosiveness, and oxygen content. Moreover, the results of the density, LHV, and octane number of the isobutanol-gasoline blends obtained from calculations can be used as a reference, but the results of the kinematic viscosity cannot.

This article investigates theoretically 12 combustion products, which are CO 2 , H 2 O, N 2 , O 2 , CO, H 2 , NO, O, H, OH, N, and NO 2 , of gasoline, diesel, ethanol, and methanol fuels at the same thermodynamics conditions. CO, CO 2 , and NO x pollutants of petroleum fuel-alcohol blends are also investigated. Petroleum fuel amount is numerically decreased in the ratios of 5-20%, and decreased amount is compensated with more alcohol to obtain the same reactant energy. Results demonstrate that concentrations of the combustion products change more with temperature and relative air fuel ratio compared to pressure. Alcohol addition into petroleum fuels decreases mostly CO and CO 2 , but no clear results exist on NO x . Blends with methanol are more effective on pollutants compared to those with ethanol.

“…Therefore numerous authors studied on prediction of emissions for particular engine parameters. Some of those concerning reciprocating internal combustion engines are given in [39][40][41][42][43][44]. Apart from those some research on emission prediction from gas turbine engines are given in [45][46][47][48][49].…”
