“…To reduce environmental pollution and harm to public health caused by diesel engines, oxygenated fuel has become a prospective solution because it can improve the combustion condition of engines and decrease PM emissions (Awad et al, 2018;Nayyar et al, 2019). As a new type of renewable oxygen-containing fuel, polyoxymethylene dimethyl ethers (PODEn) is actually a low molecular weight acetal-based polymer that is synthesized by dimethyl ether, methanol and paraformaldehyde as raw materials (Ren et al, 2019).…”

The physicochemical characteristics of particulate matter (PM) produced by polyoxymethylene dimethyl ethers (PODE2-4)/diesel blended fuel at different blend ratios was characterized using transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR) and Xray photoelectron spectroscopy (XPS). TEM analysis indicated that the overall size of PM decreased with an increasing PODE2-4 concentration. TEM images using fractal theory showed that the fractal dimension of PM increased as the PODE2-4 blending ratio increased. These trends increased the oxidation activity. FTIR was used to analyze the aliphatic C-H on the surface of PM and found that the ratio IC-H/IC=C and the aliphatic C-H functional group on the surface of PM decreased with an increasing PODE2-4 blending ratio. According to XPS data, with increments of the PODE2-4 blending ratio, the contents of O/C, sp 3 /sp 2 , C-OH, C=O and total oxygen-containing functional groups of the PM increased, demonstrating that the oxygen-containing functional group and disorder of the PM nanostructure was correlated with a faster oxidation rate. Results thus demonstrated that the addition of PODE2-4 can affect the nanostructure and oxidation activity of PM, making it easier to oxidize to reduce environmental pollution.

“…On the other hand, oxygenates and bio-additives are known to be more environmentally friendly. Nayyar et al [19] in their recent work stated that the addition of compounds rich in oxygen (oxygenates) into diesel fuel could reduce smoke and NO X production by 61.85% and 8.07%, respectively. This finding was also supported by other research [20][21][22][23], which explained how soot reduction is linearly related to the increasing oxygen mass fraction in the fuel.…”

A study on the application of oxygenated turpentine oil as a bio-additive in diesel fuel was conducted. The purpose of this research was to investigate the effect of oxygenated turpentine oil additive in diesel fuel on the performance and emission characteristics in diesel engines. Oxygenated turpentine oil is obtained from the oxidation process of turpentine oil. In this experimental study, the influences of oxygenated turpentine oil-diesel blended fuel OT0.2 (0.2% vol oxygenated turpentine oil and 99.8% vol diesel) were compared with pure diesel on engine performance, and emission characteristics were examined in a one-cylinder four-stroke CI engine. The test was performed at two engine loads (25% and 50%) and seven engine speeds (from 1200–2400 rpm with intervals of 200 rpm). The physiochemical characteristics of test fuels were acquired. The engine indicated power, indicated torque, fuel flow rate, and emissions (carbon dioxide, CO2; carbon monoxide, CO; and nitrogen oxide, NOX) were examined. The results revealed that the engine power shows slight increments of 0.7–1.1%, whereas the engine torque slightly decreased with oxygenated turpentine usage compared to pure diesel in most conditions. Furthermore, a reduction in NOX emission decreased by about 0.3–66% with the addition of oxygenated turpentine in diesel compared to diesel. However, usage of OT0.2 decreased fuel flow rate in most speeds at low load but gave a similar value to diesel at 50% load. CO emissions slightly increased with an average of 1.2% compared to diesel while CO2 emissions increased up to 37.5% than diesel. The high-water content, low cetane number, and low heating value of oxygenated turpentine oil were the reasons for the inverse effect found in the engine performances.
