“…To deeply investigate the reduction in total PN emissions, nucleation and accumulation mode particles are estimated in Figure 6. The smaller particles are much more hazardous than the bigger particles [52]. It is observed from Figure 6 that the concentration of nucleation particles is higher in comparison to that of accumulation particles at all engine loads.…”

“…In summary, the hydrous ethanol gasoline blends showed the highest reduction of the concentration of total PN compared with the anhydrous ethanol gasoline blend and gasoline. The PM emissions from the DI gasoline engine can be characterized based on size spectra as: nucleation mode particles (5 nm < Dp ≤ 30 nm), accumulation mode particles (30 nm < Dp < 100 nm) [52], and coarse mode particles (Dp >1000 nm). To deeply investigate the reduction in total PN emissions, nucleation and accumulation mode particles are estimated in Figure 6.…”

“…Therefore, researchers have used different strategies to decrease the PM emissions from PFI and DI gasoline engines [52][53][54][55][56]. Moreover, the properties of Chinese fuel are highly different, typified by higher emissions and lower engine performance [54]; thereby, the China 6a legislation has applied a particulate number limit to all engines (PFI, DI, and compression ignition (CI)) .Therefore, the purpose of this investigation is to comprehensively elucidate the effects of fuel type and blend concentration for hydrous ethanol and anhydrous ethanol gasoline blends (HE0, HE10, HE20, and E20) on the in-cylinder pressure, particulate matter emissions (size distribution, particle number, mass concentrations, and count median diameter of particles), and gaseous emissions (NO x and HC) from a port-injected gasoline engine at a speed of 2000 rev/min and various load conditions to find a correlation between PM emissions and gaseous emissions.…”

Abstract:The industrialization that increases day by day needs more and more power/fuel sources that are commonly available, abundant, renewable, and environmentally friendly. Recently, nearly all of the cities in China (PRC) have been influenced by haze. However, the pollutants from automobiles have always been seriously considered to be the main contamination causes of the haze and that influence human health. This study concerns the impact of hydrous ethanol on in-cylinder pressure, particulate matter (PM), and gaseous emissions (oxides of nitrogen (NO x ) and unburned hydrocarbon (HC)) from a port fuel injection (PFI) gasoline engine. Tests were conducted on a four-cylinder port injection gasoline engine at different engine loads at an engine speed of 2000 rev/min for commercial gasoline, hydrous ethanol-gasoline blends (10% and 20% hydrous ethanol by volume), and an anhydrous ethanol-gasoline blend (20% anhydrous ethanol by volume). The results show that the peak in-cylinder pressure with the use of gasoline was the highest compared with the hydrous ethanol and anhydrous ethanol blends. Compared with the anhydrous ethanol blend, the hydrous ethanol blends performed well at a high load condition, equivalent to a low load. In addition, the total particulate number (PN) declines with an increase in engine operating loads for all of the fuels tested. The outcome of this study is an important reduction in PM number, mass emissions, and mean diameters of particles as the use of hydrous ethanol blends increases, while the form of the particulate size distribution remains the same. Furthermore, the NO x emission is raised with a rise in engine load, and NO x and HC emissions are reduced with the use of hydrous ethanol and anhydrous ethanol blend as equated with pure gasoline. Moreover, the correlation between the total particle number against NO x and HC has been found; the number of particles increases when the NO x emission decreases, and the opposite trend is exhibited for the HC emission. Therefore, it can be concluded that hydrous ethanol blends look to be a good selection for PM, NO x , and HC reduction for gasoline engines.

Most parts of China suffer often from haze pollution, which has a huge impact on human health. Road traffic has made the largest contribution to the haze. Of all the kinds of vehicular systems, the diesel engine produces the most PM; therefore, to reduce haze pollution, it is necessary research methods to reduce the PM produced by diesel engines. HHO (Brown's gas, Rhode's gas and HRG) is formed from H 2 (60.79%) and O 2 (30.39%) as well as a small amount of water vapour and active substances, such as oxygen radicals (O) and hydroxyl radicals (OH), which have quite strong oxidizing properties in the engine process, stimulating the C-H chain reaction during the combustion period and accelerating the oxidation of HC, CO and PM emissions as a result. The influence of blending HHO with diesel on diesel engine emission characteristics is well-researched, based on an 186FA single-cylinder diesel engine. The HHO was combined with air in the intake pipe. The influence of HHO on the amount of CO, HC, NO and PM emissions was analysed by collecting data under various speeds and loads. Through MOUDI, particles of various diameters under the highest torque working conditions and declared working conditions were collected to analyse how HHO affected the particle mass distribution in different diameter ranges. The analysis showed that when the speed was stable, the quantities of CO, HC and PM created were decreased by adding HHO; in addition, HHO had the greatest effect on PM. As the load increased, the amount of CO, HC and smoke declined gradually, but the decline of NO was smaller comparatively. Moreover, after blending with HHO, the quantity of NO created increased by 9.52% when the diesel engine operated according to external characteristics, and the quantity of HC, CO and PM created decreased by 31.6%, 11.3% and 20.71%, respectively. Finally, the gross mass of the particles dropped 67.48% and 42.53% under the highest torque working conditions and declared working conditions, respectively, with the distribution of diameters moving to smaller sizes. Introducing HHO into diesel can effectively reduce the generation of PM, which plays a positive role in reducing haze pollution.
