Problems solved by technology

The fuel additives used in the existing internal purification technology have the following defects: 1) Due to the addition of organic compounds that cannot really be burned, a large amount of metal deposits gradually accumulate in the combustion chamber, oxygen sensor, and three-way catalytic converter, which easily leads to carbon deposition in the combustion chamber Deposition, three-way catalytic converter and oxygen sensor failure, leading to various related failures
2) Unable to reduce the emissions of the three major pollutants in automobiles at the same time
Often while reducing CO and HC, the effect on NOx is not obvious

Embodiment 1

[0036] Take 18kg of 4-fluorobenzylmagnesium chloride, 13.5kg of 2-(tributylstannyl)furan and 19kg of diethyl phenylphosphonate and add them to the stirring tank, stir evenly at room temperature, then add 19kg of diethyldiselenide, 14.5 kg of boron trifluoride ether and 16 kg of vanadium (V) oxide tripropanol were uniformly mixed to obtain the finished additive composition product for improving the NOx emission of M85 methanol gasoline.

[0037] With national standard gasoline as a blank control, ordinary M85 methanol gasoline was prepared with the same brand of national standard gasoline, and 0.02% of the additive composition of Example 1 of the present invention was added to ordinary M85 methanol gasoline. Use the above three oil products for power performance and exhaust emission testing. The test method is carried out in accordance with the method stipulated in "Light Vehicle Pollutant Emission Limits and Measurement Methods" (GB18352.3-2005), and the transient conventional...

Embodiment 2

[0046] Take 18kg of 4-fluorobenzylmagnesium chloride, 14.5kg of 2-(tributylstannyl)furan and 20kg of diethyl phenylphosphonate and add them to the stirring tank, stir evenly at room temperature, then add 15kg of diethyldiselenide, 15kg of boron trifluoride ether and 17.5kg of vanadium (V) oxide tripropoxide were uniformly mixed to obtain the finished additive composition product for improving the NOx emission of M85 methanol gasoline.

[0047] Figure 5 , 6 , 7 are the emission comparison charts of exhaust pollutants CO, HC and NOx, respectively. It can be seen from the figure that for the conventional pollutants CO and CH in automobile exhaust, the emission of ordinary methanol gasoline is significantly lower than that of national standard gasoline, but the NOx emission is close to that of gasoline, and there is an increase under partial load conditions. After adding 0.02% of the additive composition of Example 2 of the present invention to ordinary M85 methanol gasoline, N...

Embodiment 3

[0049] Take 25kg of 4-fluorobenzylmagnesium chloride, 16kg of 2-(tributylstannyl)furan and 15kg of diethyl phenylphosphonate and add them to the stirring tank, stir evenly at normal temperature, add 16kg of diethyldiselenide, three 12kg of boron fluoride ether and 16kg of vanadium (V) oxide tripropoxide were uniformly mixed to obtain the finished additive composition product for improving NOx emissions of M85 methanol gasoline.

[0050] Figure 8 , 9 , 10 are the emission comparison charts of exhaust pollutants CO, HC and NOx respectively. Among them, after adding 0.04% of the additive composition of Example 3 of the present invention to ordinary M85 methanol gasoline, NOx emissions were significantly improved.

Abstract

The invention discloses an additive composition for improving NOx emission in M85 methanol gasoline. The additive composition is prepared by mixing the following components: 18.0-31.0% of 4-fluorobenzylmagnesium chloride, 15.0-29.5% of diethyl diselenide, 15.0-24.5% of diethyl benzylphosphonate, 13.0-24.0% of tripropanol vanadium oxide (V), 10.0-20.5% of trifluoride diethyl etherate and 9.0-19.5% of 2-(tributyltin alkyl) furan. The additive composition has an obvious effect of improving the NOx emission in M85 methanol gasoline at high proportion; when 0.02-0.05% of the additive composition is added into common M85 methanol gasoline, the NOx emission can be reduced by over 30%.

Description

technical field [0001] The invention belongs to the technical field of methanol replacing vehicle fuel, and relates to an additive for M85 methanol gasoline, in particular to an additive for improving the NOx emission of M85 methanol gasoline. Background technique [0002] As the world's oil resources become increasingly scarce and air pollution becomes increasingly serious, the energy crisis has become a bottleneck restricting economic development, and new alternative fuels have attracted the attention of all parties. my country's dependence on foreign oil has exceeded 53%, and energy and environmental issues restrict the rapid development of my country's economy. my country is a country that is poor in oil and gas but relatively rich in coal. It is entirely feasible to replace part of the oil with coal to produce methanol. Using methanol as a substitute fuel for internal combustion engines is an effective way to protect the environment and use energy rationally. [0003] ...
