Problems solved by technology

[0002] Energy shortage is one of the problems faced by human development. In order to save the existing petrochemical energy, people have carried out extensive research, such as the improvement of internal combustion engines, the modification of fuel oil, and the development of fuel additives. However, in practical applications, many There are different degrees of deficiencies. The modification of internal combustion engines is often too cumbersome, and in the actual use process, new problems are caused due to the difference in fuel quality. Insufficient power, low calorific value, etc., and various fuel additives on the market are mostly designed for a specific aspect of the problem, and often contain harmful corrosion, toxic substances, and flammable and explosive substances that will bring safety hazards chemicals

Embodiment 1

[0014] One way to improve fuel efficiency:

[0015] (1) Preparation of fuel additive: the fuel additive is made from the following raw materials in weight ratio:

[0016] 90 parts of SF grade engine oil for gasoline engine, 0.5 part of BHT, and 0.5 part of lanthanum; the preparation method is as follows: heat all raw materials to 85°C under anaerobic conditions, keep them warm for 24 hours, then cool to room temperature, concentrate, separate, and remove more than The liquid particle of 5 microns promptly gets the fuel additive of the present invention;

[0017] (2) Atomization of fuel additive: inject and atomize the fuel additive, control the atomized particle size to be less than 5 microns, and the injection amount is 0.08% of the fuel amount. The atomized steam and air are sent into the combustion chamber and mixed with fuel for combustion.

Embodiment 2

[0019] (1) Preparation of fuel additive: the fuel additive is made from the following raw materials in weight ratio:

[0020] 90 parts of SF grade engine oil for gasoline engine, 0.5 part of BHT, and 0.5 part of lanthanum; the preparation method is as follows: heat all raw materials to 85°C under anaerobic conditions, keep them warm for 24 hours, then cool to room temperature, concentrate, separate, and remove more than The liquid particle of 5 microns promptly gets the fuel additive of the present invention;

[0021] (2) Atomization of fuel additives: evaporate and atomize fuel additives, control the evaporation particle size to be less than 5 microns, inject 0.03% of the fuel, and send the atomized steam and air into the combustion chamber for mixed combustion with the fuel.

Abstract

The invention discloses a fuel efficiency improvement method. The method includes the steps of: (1) preparation of a fuel additive: the fuel additive is prepared from the following raw materials by weight: 90-100 parts of lubricating oil, 0.5-2 parts of an antioxidant and 0.5-2 parts of a lanthanide rare earth metal, the lubricating oil is internal combustion engine lubricating oil with mineral oil as the base oil, preferably gasoline engine SF grade engine oil and diesel engine CD grade engine oil; the antioxidant is BHT, diphenylamine antioxidant or 3, 7-diisooctyl phenothiazine; the lanthanide rare earth metal is lanthanum, praseodymium or erbium; and (2) atomization of the fuel additive: subjecting the fuel additive to jet atomization or evaporation atomization, and sending atomizationsteam and air into a combustion chamber together for mixed combustion with fuel. The method achieves a fuel saving rate of at least 20%, at the same time discharges NOx, CO and hydrocarbon substancesin the tail gas, the tail gas emission is far superior to the state V standard, the discharge of pollutants is greatly reduced, and the carbon emissions are significantly reduced.
