“…Biodiesel obtained from nonedible sources is a viable option in CI engines for commercial applications. Compared to mineral diesel, biodiesel has many advantages such as biodegradability, safer storage, better lubricity, low toxicity, and environ-ment friendly [1]. Algae oils with low to medium viscosity can be modified to obtain the properties equivalent to diesel by a suitable chemical process.…”

Numerous Algae oils with low and medium viscosity were investigated as fuel for CI engines. However, high viscous algae oil has not been explored in detail as a replacement for diesel in CI engines due to operational problems and poor performance characteristics. Esterification of neat algae oil to obtain its biodiesel is a complex process. The biodiesel obtained also has viscosity nearly five times more than diesel viscosity. Hence, research efforts on CI engines using algae oil methyl ester are lacking, particularly in combustion characteristics. This work focuses on utilizing algae oil as a fuel in CI engines. Algae oil has more affinity for alcohols due to a higher percentage of ricinoleic acid which aids in forming a homogeneous mixture. Alcohols with better fuel properties improve the combustion capability of algae oils with low and medium viscosity. However, not much research has been carried out in alcohols with very high viscous algae oil. Hence, in this work, higher and lower-order alcohols were blended with algae oil in their neat form and their biodiesel with Al2O3 nanoadditives for performance improvement.

“…To reduce NO x -soot emissions, the reactivity of fuel and air–fuel mixture formation should be controlled with low-temperature combustion. The engine PPCI mode has received substantial attention in the current time as mentioned in previous studies. ,, Furthermore, the RCCI engine was developed by Kokjohn et al through varying equivalence ratio stratification and the fuel reactivity inside the engine using high and low reactivity of fuels. The dual fuel-based PPCI engine has been introduced by Inagaki et al, which extends the engine operating range over high operation conditions of engine load and reduces the charge dilution levels.…”

“…The PPCI combustion improves the mixing between air and fuel, in which premixed combustion can occur in the combustion chamber without diffusion flame . The concept of PPCI can be achieved during the combination of high exhaust gas recirculation (EGR) levels and manipulation in the injection timing . Hountalas et al reported that the poor combustion process can occur due to the reduced oxygen availability inside the cylinder under higher EGR temperature.…”

Reducing the Effect of High Sulfur Content in Diesel Fuel on NO_x Emissions and PM Characteristics Using a PPCI Mode Engine and Gasoline–Diesel Blends

et al. 2022

Recently, high sulfur content in diesel fuel is one of the main problems that have an effect on combustion and emission characteristics. Iraq is one of many countries in the world that use diesel fuel with high sulfur content. Therefore, the partially premixed combustion ignition (PPCI) concept and different blend ratios of gasoline–diesel (GD30, GD40, and GD50) were suggested in this study to reduce the sulfur content in the fuel, improve the engine performance, and reduce the exhaust emissions. The combined effect of adding gasoline to the diesel fuel and manipulating the fuel injection timings can lead to better and clean combustion. For the same engine operating conditions, it is found that the brake thermal efficiency (BTE) decreases during the combustion of GD blends in comparison with diesel fuel. Furthermore, the results of using GD blends showed a small reduction in brake-specific fuel consumption (BSFC) compared to the conventional diesel fuel. The exhaust gas temperature reduces from the combination effect of PPCI mode and GD blends, which in turn decreases the NO x emission concentration under variable conditions of engine loads and speeds. It is indicated that the NO x emissions significantly decreased during the combustion of GD30, GD40, and GD50 blends by 25.94, 50.9, and 84%, respectively, in comparison with diesel fuel. In addition, higher reduction in CO and HC formation was obtained during the combustion of conventional fuel in comparison with the combustion of GD blends. The results showed that the number and concentration of PM reduced more when using GD blends and PPCI mode. The average particle diameter (d p) decreased from the combustion of GD blends in comparison with diesel fuel. The particle diameter of the GD blend was varied from 25 to 26 nm compared to those of diesel fuel of 35 and 36 nm under the same engine operating conditions. Reducing the sulfur content in GD blends contributed to a clear reduction in SO2 and H2S emissions by 57.85 and 50.12%, respectively.

“…There are many effective solutions to reduce emissions from diesel engines such as improving combustion quality, adjusting the engine structure, and installing an exhaust gas treatment system, as described in Figure 1. Although the community of researchers has implemented emission treatment solutions such as exhaust gas recirculation (Hoang, 2018), catalytic reduction selectivity (Pham, 2019), optimization for injection strategy (Hoang, 2020a) (Nayak and Mishra, 2016) (Hoang, 2020b) and piston-top geometry and adding nanoparticles (Hoang, 2021). However, those solutions are complex and have to accept their tradeoffs for other emissions or engine modifications.…”

Today, most of the essential energy needs of humans and production are met by fossil fuels that are expected to be exhausted in the next century. Furthermore, fossil fuels are not renewable and sensitive to the environment. In particular, there is growing concerned about the negative impact of internal combustion engine emissions on climate change and global environmental pollution. Fuel and alcohol-based additives are being considered as good candidates for sustainable alternative fuels used on compression ignition engines. In this review, the different key production pathways and properties of each of the five alcohol additive candidates were discussed. Besides, their effects on the emission characteristics of diesel engines when alcohol additives are added to diesel fuel are also carefully considered. Five candidates including methanol, ethanol, propanol, butanol, and pentanol have been shown to control pollutants from combustion engines while using alcohol-based additives. This is of great significance in the strategy of coping with the threats of pollution and climate change caused by the operation of transport vehicles
