Problems solved by technology

However, due to the poor miscibility between alcohol fuel and diesel oil, it is impossible to achieve a large proportion of miscibility with diesel oil without the aid of co-solvents. The value is obviously reduced, so it is not suitable for use as plateau oxygen-containing diesel oil

Embodiment Construction

[0014] The present invention will be further described below in conjunction with embodiment.

[0015] A new type of plateau oxygen-containing diesel oil, mixing the diesel substitute component and No. 0 diesel oil on the market at room temperature, fully stirring and then standing for 5-10 hours, which is the plateau oxygen-containing diesel oil of the present invention, and then applying it in areas with an altitude of 3000m On diesel locomotives, compared with pure diesel, see Tables 1, 2, 3, 4, 5 and 6, where A represents polyethylene glycol dimethyl ether, B represents polyethylene glycol diethyl ether, and C represents polyethylene glycol diethyl ether. Formaldehyde dimethyl ether, D is the percentage that diesel oil of the present invention compares with pure diesel oil, and its external characteristic power of the engine improves on average; E is the percentage that its oil consumption reduces on average for diesel oil of the present invention and pure diesel oil; F is t...

Abstract

The invention discloses novel plateau oxygen-containing diesel oil. The novel plateau oxygen-containing diesel oil is characterized by comprising the following ingredients by volume fraction: 5%-30% of a diesel oil alternative ingredient and 70%-95% of diesel oil, wherein the diesel oil alternative ingredient is composed of polyethylene glycol dimethyl ether or polyethylene glycol diethyl ether, or is composed of two or more of polyethylene glycol dimethyl ether, polyethylene glycol diethyl ether and metaformaldehyde dimethyl ether; polyethylene glycol dimethyl ether comprises 1-4 polymers; polyethylene glycol diethyl ether comprises 1-4 polymers; metaformaldehyde dimethyl ether is a trimer or a tetramer. The novel plateau oxygen diesel oil can relieve incomplete combustion of diesel oil caused by poor plateau oxygen, improves the dynamic performance of a diesel engine, and reduces oil consumption and soot emission; the diesel engine does not need transformation, the cost for developing a plateau diesel engine is saved, and the novel plateau oxygen diesel oil has relatively high social benefit and economic benefits, and is strong in practicability.

Description

technical field [0001] The invention belongs to the technical field of plateau diesel oil, and in particular relates to a novel plateau oxygen-containing diesel oil. Background technique [0002] When diesel engines operate in plateau areas, due to the influence of special geographical environment and climatic conditions, their power, economy, reliability and exhaust emissions are all greatly reduced. Some researchers have found through experimental research that compared with an altitude of 500m, the maximum power of the test points at 2000m, 3000m and 4000m decreased by 12.1%, 17.3% and 43.8% respectively, and the fuel consumption rate increased by 9.5%, 20.2% and 34% respectively, and Soot emissions also increase significantly with altitude. [0003] This situation is mainly due to the gradual decrease of atmospheric temperature and pressure with the increase of altitude. The decrease in temperature leads to an increase in the viscosity of the fuel oil, resulting in poo...
