“…47 Moreover, the smoke precursors is inhibited by the complete combustion because of the oxygen content of ethanol and the less multi-ring aromatic in the microemulsions, so the large sized particles are reduced. 48,49 With the advance of PIT or the increase of PIQ, PNC of each sized particles is slightly decreased. For two-stage injection strategy, the pilot fuel has enough time to mix with air, thus the smoke is mainly produced by the combustion of main fuel.…”

This study investigated the effect of pilot injection timing (PIT) and pilot injection quantity (PIQ) on the performance of a common rail direct injection (CRDI) diesel engine with two-stage injection system operating with diesel-palm oil-ethanol micro-emulsions. The results indicated that, at low engine load, the maximum in-cylinder pressure (Pmax) and peak of heat release rate (HRR) of D35P35E30 were highest, and those of D100 were lowest. At high engine load, the Pmax of D100 was highest, that of D60P30E10 was lowest, and the peaks of HRR were almost identical for all test fuels. The Pmax and peak of HRR were slightly increased with the advance of PIT. Increasing PIQ increased the first peak of HRR and reduced the second one. At low engine load, the coefficient of variation (COV) of Pmax and the indicated mean effective pressure (IMEP) presented a slight decrease for the micro-emulsions, but did for D100 at high engine loads. The brake specific fuel consumption (BSFC) of the micro-emulsions was higher, and the brake thermal efficiency (BTE) was also slightly higher when compared with diesel (D100). With the advance of PIT and the increase of PIQ, BSFC was increased, BTE was decreased, and hydrocarbon (HC) emissions were reduced. The variation of PIT and PIQ had little effect on the particle number concentration (PNC), but had evident effect on nitrogen oxides (NOx) emissions. It was concluded that the micro-emulsions can be used to reduce NOx and particulate matter (PM) simultaneously combined with injection strategy in a diesel engine.

“…(El-Seessy et al2018) studied the impact of nanoparticle additives blended biodiesel to study the performance characteristics of diesel engine on various loading conditions by adding different ANPs (aluminium oxide nanoparticles) concentrations and reported that at full load condition, there was a decrease in various exhaust emissions like hydrocarbons reduced by 80%, nitrogen oxides by 70% and carbon monoxide reduced by 60%. Ghadikolaei et al (2019) studied the formation of particulate matter and chemical properties of ternary fuel blend of ethanol-biodiesel-diesel, at various load conditions. They found out that this type of blend has a better impact on DPFE (diesel particulate lter e ciency) and the obtained value of metal elements was 0.7% and ions 1.9% and diesel particulate matter was 85.8%.…”

This paper deals with the study on the in uence of the effects of iron oxide nanoparticle additives when added to ternary fuel (diesel + Mahua methyl ester + Pentanol) on the emission, combustion and performance characteristics of a four stroke, single cylinder, common rail direct injection diesel engine working at a constant speed and varying operating scenarios. Doping is done in various proportions to the nanoparticle additives with the help of a homogenizer and ultrasonicator where the cationic surfactant used is CTAB (cetyl trimethyl ammonium bromide). Iron oxide nanoparticles were used as additives in fuel in the dosages of 40 ppm, 80 ppm & 120 ppm respectively and TF (Ternary fuel) is obtained by mixing 10% pentanol, 20% Mahua and 70% diesel together is used for the experimental study. The experimental study revealed that while using the nanoparticle additives blended ternary fuel (i.e., TF80) the number of harmful pollutants like smoke (5.38%), HC (6.39%), carbon monoxide (10.24%) and NO x etc. has reduced to a considerable extent and there was a commendable improvement in the BTE by 8.8%. So, we can summarize that when ternary fuel and nano additives are blended together the combustion and performance of the engine was improved considerably and pollutant emissions were decreased.

“…Carbon dioxide, although harmless to living organisms, is considered one of the main causes of climate warming. On the other hand, the exhaust contains some number of small particles of solid, liquid, and gaseous substances [1] forming an aerosol with the air, so-called "smog". This makes breathing difficult, and some of the individual substances contained in it can cause various diseases or lead to poisoning.…”

The trend to replace traditional fossil fuel vehicles is becoming increasingly apparent. The replacement concerns the use of pure biofuels or in blends with traditional fuels, the use of hydrogen as an alternative fuel and, above all, the introduction of electric propulsion. The introduction of new types of vehicle propulsion affects the demand for specific fuels, the needs for new infrastructure, or the nature of the emissions to the environment generated by fuel production and vehicle operation. The article presents a mathematical model using the difference of two logistic functions, the first of which describes the development of the production of a specific type of vehicle, and the second, the withdrawal of this type of vehicle from traffic after its use. The model makes it possible to forecast both the number of vehicles of each generation as a function of time, as well as changes in energy demand from various sources and changes in exhaust emissions. The results of the numerical simulation show replacing classic vehicles with alternative vehicles increases the total energy demand if the generation of the next generation occurs earlier than the decay of the previous generation of vehicles and may decrease in the case of overlapping or delays in the creation of new vehicles compared to the course of the decay function of the previous generation. For electric vehicles, carbon dioxide emissions are largely dependent on the emissions from electricity generation. The proposed model can be used to forecast technology development variants, as well as analyze the current situation based on the approximation of real data from Vehicle Registration Offices.
