“…Ghazal [11] investigated the effect of H 2 /diesel blend fuel ratio, engine speed, and air/fuel ratio on CI engine performance and emissions. The results showed that the hydrogen concentration between (30%-40%) with (A/F) ratio range (15)(16)(17)(18)(19)(20) improves the engine production power and brake thermal efficiency with a reduction of emissions. The reactivity controlled compression ignition engine (RCCI) which combines two or more fuels with different reactivity (such as diesel and gasoline) is another promising technology to provide low emissions and high engine performance compared to a conventional diesel engine.…”

“…In addition, the ignition delay is increased as the gasoline ration increased in the mixture. Cha et al [17] studied the effect of gasoline quantity in the fuel mixture and the diesel injection timing on the combustion and emission characteristic for compression ignition engine. The results showed that gasoline addition reduces soot and NO emissions by eliminating the high temperature region in the combustion chamber.…”

Several automobile manufacturers are interested in investigating of dual fuel internal combustion engines, due to high efficiency and low emissions. Many alternative fuels have been used in dual fuel mode for IC engine, such as methane, hydrogen, and natural gas. In the present study, a reactivity controlled compression ignition (RCCI) engine using gasoline/diesel (G/D) dual fuel has been investigated. The effect of mixing gasoline with diesel fuel on combustion characteristic, engine performance and emissions has been studied. The gasoline was injected in the engine intake port, to produce a homogeneous mixture with air. The diesel fuel was injected directly to the combustion chamber during compression stroke to initiate the combustion process. A direct injection compression ignition engine has been built and simulated using ANSYS Forte professional code. The gasoline amount in the simulation varied from (50%-80%) by volume. The diesel fuel was injected to the cylinder in two stages. The model has been validated and calibrated for neat diesel fuel using available data from the literature. The results show that the heat release rate and the cylinder pressure increased when the amount of added gasoline is between 50%-60% volume of the total injected fuels, compared to the neat diesel fuel. Further addition of gasoline will have a contrary effect. In addition, the combustion duration is extended drastically when the gasoline ratio is higher than 60% which results in an incomplete combustion. The NO emission decreased drastically as the gasoline ratio increased. Moreover, addition of gasoline to the mixture increased the engine power, thermal efficiency and combustion efficiency compared to neat diesel fuel.

One of the various efforts to reduce PM and NO emissions from modern diesel engines is the use of light fuels fumigation as supplement to pilot injected diesel fuel. Present work aims at developing a fumigation system for introduction of gasoline in a diesel engine with mechanically‐controlled fuel injection pump and to determine its effects on emission. Experiments were performed on a 4‐cylinder direct‐injection diesel engine operating at two constant engine speeds for different engine loads. Diesel fuel was considered as baseline fuel and gasoline was inducted as fumigation in intake manifold at two different ratio on every operation modes. The experimental results show that with gasoline fumigation, the specific NOx and CO2 emission decreased to about 28, and 7% (averaged on all engine loads), respectively in comparison with baseline diesel case. While smoke opacity decreases at high loads up to 50%. However, increase in the specific CO and HC emission have been found after use of premixed gasoline at all loading conditions. Moreover, gasoline fumigation can improve brake thermal efficiency slightly at intermediate and high loads. Thus, gasoline fuel as premixed fuel with fumigation method showed a favorable potential in terms of reduction of main emissions and improvement performance in diesel engines with mechanically‐controlled fuel injection pump. © 2017 American Institute of Chemical Engineers Environ Prog, 37: 1845–1852, 2018

In recent years there has been a significant rise in crude glycerol generation due to the booming biodiesel industries. Despite having immense benefits, the presence of poisonous methanol and fatty acids, glycerol is treated as a waste by‐product of biodiesel. In the present study, investigations have been carried out on utilizing the potential of glycerol derived bio‐propanol as an extender fuel with diesel/gasoline blends. Test fuels containing ternary blends of diesel/gasoline/bio‐propanol in different volume concentrations were prepared. The crude glycerol was procured from transesterified Kusum (Schleichera oleosa) oil. The physicochemical properties, along with stability and homogeneity of the test fuels were evaluated as per ASTM/EN standards and compared with the neat diesel. To study the effect of fuel properties on atomization process, the sauter mean diameter of the test fuels were observed using Malvern spraytec test. The engine performance, combustion and emission characteristics of a single‐cylinder diesel engine fuelled with different test fuels were also conducted. Due to the enhancement in mixing rate promoted by low cetane fuels, the ignition delay and heat release rate was higher than diesel. Moreover, the results also reveal upto 5% increase in brake thermal efficiency and a significant reduction in harmful exhaust emission with an increase in the gasoline and bio‐propanol share in the blend. The oxide of nitrogen (NOx) emissions was also lower than diesel for all the fuel blends. In comparison to diesel, the maximum reduction in NOx, HC, CO and smoke emissions is 7.4%, 33.3%, 55.7%, and 17.2%, respectively, for D40:G30:P30 fuel blend.
