Emulsified diesel oil for automobile

Abstract

The invention discloses emulsified diesel oil for vehicle. According to volume portion, the composition formulation comprises 40 to 70 portions of diesel oil, 10 to 30 portions of methanol, 10 to 20 portions of water, 0.5 to 1.5 portions of ethyl nitrate, 0.8 to 1.8 portions of polyoxyethylene nonyl phenyl ether, 0.2 to 0.7 portions of cyclopentyl ferrocene, 1.0 to 2.0 portions of acetone, 0.0 to 0.7 portions of petroleum sodium sulfonate, 1.0 to 1.5 portions of isoamyl alcohol and 1.3 to 1.8 portions of normal hexane. The viscosity, condensation point, flash point and cetane value of the emulsified diesel oil are all accorded with the index requirements of diesel oil for vehicle, and the source of the required raw materials and auxiliary materials is wide, the price is low and the exhaust emission is accorded with the requirements of the 3# European standard; by using the emulsified diesel oil, the fuel saving rate can reach 28%, the wearing of the cylinder jacket and the piston ring of the diesel engine is reduced by 25% for running 3,500 hours comparing with using pure diesel oil; the implementation of the invention has important economic value and social significance.

Description

technical field [0001] The invention relates to an emulsified diesel oil for vehicles and belongs to the technical field of clean fuels. Background technique [0002] In the late 20th century, affected by the rise in international oil prices and the shortage of oil resource supply, there was a serious shortage of diesel oil at home and abroad, which brought great inconvenience to economic development and people's lives; Sufficiently, the content of particulate matter, nitrogen oxides and hydrocarbons in the exhaust gas is very high, causing serious pollution to the environment. In order to reduce the consumption of non-renewable energy, reduce the amount of diesel used by diesel engines and reduce environmental pollution, emulsified diesel came into being. As research results at home and abroad show that emulsified diesel oil does not corrode and increase wear on internal combustion engines, but can act as a cleaning agent and reduce maintenance costs for internal combustio...

Problems solved by technology

[0002] In the late 20th century, affected by the rise in international oil prices and the shortage of oil resource supply, there was a serious shortage of diesel oil at home and abroad, which brought great inconvenience to economic development and people's lives; Sufficient, so that the content of particulate matter, nitrogen oxides and hydrocarbons in the exhaust gas is very high, causing serious pollution to the environment

Because the viscosity, freezing point, flash point and cetane number of emulsified diesel oil can meet the index requirements of vehicle diesel oil, a certain amount of emulsifier is required to prepare emulsified diesel oil, and the emulsifier disclosed in the prior art either has a price It is more expensive, and there is a phenomenon of saving fuel and not saving money, which greatly affects the economy of emulsified diesel oil; or the stability of emulsified diesel oil is not good, and it will be deformed or demulsified as the environment and conditions change and the storage time becomes longer. and other unstable phenomena, which affect the safety of emulsified diesel oil; or it cannot solve the problems of viscosity, freezing point, flash point, cetane number, etc., and cannot be used in diesel vehicles
