Embodiment 1
[0096] Embodiment 1 Oxalate is used as the miscibility research of alternative fuel oil or fuel oil additive
[0097] There are many kinds of organic compounds that can be used as alternative fuels. The physical and chemical properties of common fuels and common alcohol ether esters are shown in Table 1.
[0098] Since dimethyl oxalate is solid at room temperature and has poor compatibility with gasoline and diesel, there has been no research on dimethyl oxalate and its derivatives including asymmetric oxalate as a large-scale fuel additive or substitute. At present, there are only reports on the use of diethyl oxalate, diisoamyl oxalate, and butyl oxalate as additives in the literature, and there is no detailed evaluation of a large number of substitutions and use effects. Due to reasons such as high production costs, no one develops it as a large-scale fuel additive or substitute.

Embodiment 2
[0126] The fuel performance evaluation of embodiment 2 oxalates
[0127] In order to compare the work efficiency and emission effect, we carried out the bench test evaluation of the mixed fuel engine. The experiment was carried out on a 4G15S four-cylinder gasoline engine with a speed of 3000r / min. The emission of mixed gasoline mixed with 40%wt methyl ethyl oxalate was compared with that of pure gasoline, which proved that the gasoline sample mixed with oxalic acid mixed ester was more fully combusted, and PM2.5 and CO emissions were significantly reduced. The equivalent fuel consumption rate is reduced and the thermal efficiency is improved, indicating that the addition of mixed esters can increase the output, improve the combustion effect, and reduce pollutant emissions. It has the advantages of being more environmentally friendly and safer than gasoline and diesel (see Examples 5-8 for details).
[0128] It can be seen from Table 8 below that the energy density of gasoli...
Embodiment 3
[0140] The combustion performance research of embodiment 3 oxalic acid esters
[0141] The oxalate compound itself requires a lower oxygen consumption and a lower air-fuel ratio for combustion. For specific indicators, see Table 10 below.
[0142] The performance index measurement of table 10 oxalate
[0143] fuel or additive oxygen consumption air-fuel ratio Dimethyl oxalate 0.95 4.07 Ethyl Oxalate 1.21 5.20 Diethyl oxalate 1.42 6.11 Methyl butyl oxalate 1.60 6.87 ethyl butyl oxalate 1.75 7.50 Dibutyl oxalate 1.98 8.50 Methyl octyl oxalate 2.07 8.90 Methyl oxalate C18 ester 2.61 11.19 Methyl oxalate C22 ester 2.72 11.67 Methanol 1.50 6.44 ethanol 2.09 8.96 Isooctane 3.51 15.06 gasoline 14.70
[0144] It can be seen from Table 10 above that the oxygen consumption of oxalate ester combustion is greater than or equal to 0.95 and less than or equal to 2.8, and the air-fu...
