Problems solved by technology

However, many years of practical experience have shown that low-temperature stratification and immediate stratification when encountering excess water are the most critical factors restricting the large-scale application of methanol gasoline
Of course, adding 2-4% co-solvent is a relatively recognized method in the industry, but the high cost limits its application, so it is very necessary to develop a low-cost solubilization technology

Embodiment 1

[0029] Embodiment one: the configuration of mixed alcohol gasoline sample

[0030] Numbering

Embodiment 2

[0032] The sample prepared in Example 1 was subjected to the M111E engine bench test according to the national standard GB19592 gasoline detergent, and the average value of the intake valve deposits was 29 mg, which was far less than the average value of the gas valve deposits specified in the standard. 70 mg limit

Embodiment 3

[0033] Embodiment 3: Simulated emission test

[0034] Choose engine bench rapid aging or engine oil gasoline catalytic aging system (FOCAS-Fuel Oil Catalyst Aging System) for rapid aging. This proprietary equipment can be flexibly applied to various oil products, and has higher control accuracy and flexibility. At the same time, it is required to select a prototype car that meets the National III standard, which requires good mechanical properties and a driving mileage between 3000 and 5000km. Purchase 2 catalytic converters that were recorded during the type approval of the vehicle. The required volume and precious metal formula are the same, and the precious metal content of one catalytic converter is about 1.5 times that of the other catalytic converter;

[0035] Follow these steps to experiment:

[0036] According to national standard GB18352.3-2005, use the gasoline that embodiment one provides, carry out type I emission test on sample car;

[0037] According to the na...

Abstract

The invention relates to the technical field of vehicle fuel, in particular to a fuel composition capable of meeting a motor vehicle pollutant emission limit. In the invention, a mixture of lower alcohol, a nitro compound, a cosolvent, a gasoline detergent, an antioxidant and a rust inhibitor are added into gasoline according to a certain mixture ratio, and gasoline which is generally recognized as low quality can also enable the emission of the motor vehicle pollutant to reach the level of gasoline with high quality. Simultaneously, the use properties comprising gasoline consumption, dynamicproperties and the like basically approach to those of common gasoline. The usage amount of the cosolvent with high cost is farthest reduced under the condition of ensuring that the use properties ofmixed alcohol gasoline, especially on a water-resistant sublayer and a low-temperature sublayer, with similarity to those of common ethanol gasoline. Compared with common methanol gasoline, the usageamount of the cosolvent is reduced by more than 65%.

Description

technical field [0001] The present invention relates to the technical field of automobile fuels, in particular to a fuel composition that satisfies motor vehicle pollutant discharge limits; The combined effect of these agents can make motor vehicle pollutant emissions reach the level of high-quality gasoline even on gasoline that is generally considered to be low-quality. At the same time, in terms of performance, including fuel consumption and power, it is basically close to ordinary gasoline. Background technique [0002] As early as 1930, ethanol / gasoline blended fuel was available in the Nebraska region of the United States; in 1978, gasoline containing 10% ethanol was used on a large scale in the state; in 1979, the US Congress to reduce dependence on imported crude oil From the perspective of alternative energy, the federal government's "ethanol development plan (using E10, reducing federal consumption tax)" was established, and began to vigorously promote the use of ...
