Problems solved by technology

The above surfactant-containing additives, because the surfactant can better disperse the dissolved water in the fuel, can lower the freezing point of the fuel, clean the sludge and deposits in the fuel system, improve combustion, and reduce NO x and many other functions, but the dosage is relatively large, and the combustion-supporting and pollution-reducing performance is limited

Embodiment 1

[0034] The preparation method of the ashless diesel oil additive of the present invention is to use a mechanical stirrer or an ultrasonic stirrer to mix 30 grams of sorbitan monostearate, 20 grams of lauryl alcohol polyoxyethylene ether, and 5 grams of nonylphenol polyoxyethylene ether , 15 grams of alcohol acetal glyoxal, 10 grams of distilled water, 10 grams of n-butanol, 10 grams of 200 # Solvent oil, fully mixed evenly, made into a transparent ashless diesel oil cleaning additive. When the amount added to diesel is 1000ppm, the idling emission results of diesel vehicles show that CO31%, HC37%, NO x 12%, smoke 32%.

Embodiment 2

[0036] The preparation method of the ashless diesel oil additive of the present invention is to use a mechanical stirrer or an ultrasonic stirrer to mix 20 grams of sorbitan monostearate, 20 grams of lauryl alcohol polyoxyethylene ether, and 20 grams of nonylphenol polyoxyethylene ether Nitrates, 15 grams of alcohol acetal, 10 grams of distilled water, 10 grams of n-butanol, 10 grams of 200 #Solvent oil, fully mixed evenly, made into a transparent ashless diesel oil cleaning additive. When the amount added to diesel is 1000ppm (body), the idling emission results of diesel vehicles show that CO34%, HC35%, NO x 12.8%, smoke 34%.

Embodiment 3

[0038] The preparation method of the ashless diesel oil additive of the present invention is to use a mechanical stirrer or an ultrasonic stirrer to mix 5 grams of sorbitan monostearate, 20 grams of polyoxyethylene lauryl ether nitrate, and 20 grams of nonylphenol polyoxyethylene Vinyl ether nitrate, 15 grams of octylphenol polyoxyethylene ether, 15 grams of alcohol acetal, 10 grams of distilled water, 10 grams of n-butanol, 10 grams of 200# solvent oil, fully mixed to make a transparent ash-free Diesel cleaning additive. When the amount added to diesel is 1000ppm (body), the idling emission results of diesel vehicles show that CO36%, HC39%, NO x 14.3%, smoke 35%.

Abstract

The present invention relates to an ash-less diesel oil additive, its preparation and application method. Said additive is formed from sorbitan monostearate, alkylolpolyethenoxyether and its derivative, alkylphenolpolyethenoxyether and its derivative, alcohol diethoxyethane, water, medium carbon alcohol and solvent oil, and its preparation method includes: mixing sorbiton nanostearate, alkylolpolyethenoxyether and its derivative and alkylphenol polyethenoxyether and its derivative by using mechanical stirring device or ultrasonic stirrer, then adding other materials successively and fully stirring them to obtain the transparent solution, i.e. said invented product which can improve combustion property of diesel oil and reduce discharge of CO, NOx, HC and PM pollutants in the tail gas, andcan prevent secondary pollution.

Description

technical field [0001] The invention belongs to the field of fuel additives, in particular to an ashless diesel oil additive for improving the combustion performance of diesel oil and reducing the discharge of diesel engine tail gas pollutants, as well as its preparation method and use method. Background technique [0002] Diesel is combusted in a compression ignition engine. Due to various reasons, the incomplete combustion discharges a large amount of pollutants, which seriously pollutes the environment. The main pollutants emitted by diesel engine exhaust are: carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NO x ) and particulate matter. The main method to reduce diesel engine pollutant emissions is to improve the quality of diesel, improve the engine structure and use diesel additives. At present, there are two types of diesel additives: ash-free additives and ash-containing additives. There are ash additives, such as ferrocene, barium petroleum sulfonate, e...
