M10, M15, M50 methanol gasoline and 93 # gasoline engine emission performance test were researched on the engine GW491QE. Always stayed in 60 N·m torque and rotational speed increased from 1000 r/min to 3000 r/min, recorded the corresponding data, performance, emission performance curve was drawn respectively, comparison and analysis, the influencing factors of GW491QE engine emission performance were discussed, practical application on engine GW491QE suitable blending ratio of methanol gasoline was chosen. The experimental results show that: three kinds of methanol gasoline of HC emissions is lower, M15 improvement is most obvious; NOx emissions are reduced. GW491QE engine emission performance is taken into account, M15 methanol gasoline is a good proportion of the actual application.

AbstractTightening noose on engine emission norms compelled manufacturers globally to design engines with low emission specially NOx and soot without compromising their performance. Amongst various parameters, shape of piston bowls, injection pressure and nozzle diameter are known to have significant influence over the thermal performance and emission emanating from the engine. This paper investigates the combined effect of fuel injection parameters such as pressure at which fuel is injected and the injection nozzle size along with shape of piston bowl on engine emission and performance. Numerical simulation is carried out using one cylinder naturally aspirated diesel engine using AVL FIRE commercial code. Three geometries of piston bowls with different tumble and swirl characteristics are considered while maintaining the volume of piston bowl, compression ratio, engine speed and fuel injected mass constant along with equal number of variations for injection nozzle size and pressures for this analysis. The investigation corroborates that high swirl and large turbulence kinetic energy (TKE) are crucial for better combustion. TKE and equivalence ratio also increased as the injection pressure increases during the injection period, hence, enhances combustion and reduces soot formation. Increase in nozzle diameter produces higher TKE and equivalence ratio, while CO and soot emission are found to be decreasing and NOx formation to be increasing. Further, optimization is carried out for twenty-seven cases created by combining fuel injection parameters and piston bowl geometries. The case D2H1P1 (H1 = 0.2 mm, P1 = 200 bar) found to be an optimum case because of its lowest emission level with slightly better performance.
