Ashless diesel fuel additive, and its preparing method and use method

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...
