Abstract
The present invention discloses a clean fuel special for a diesel engine, which is composed of 50 to 95 wt% of pentane and 5 to 50 wt% of diesel oil. Compared with the prior art, the present invention has the following characteristics that tail gas pollution can be sufficiently and effectively reduced, flames are stable and thorough when combustion is carried out, nitric oxide and black smoke are substantially reduced when exhaust is carried out, and FSN values are lower than 0.5; economic performance is good, production costs can be reduced, and the oil consumption of a motor vehicle is effectively reduced; the present invention is easy to popularize and use. The present invention can be used by the existing filling station system which is slightly and properly adjusted, fuel filling systems need not be reconstructed, and favorable conditions are created to popularize and use a clean fuel.
Description
The present invention relates to a kind of diesel engine fuel.
According to showing about statistical information both at home and abroad, the air ambient of metropolitan area pollutes and comes from various Motor vehicles more than 70%, because the height of Motor vehicles Waste gas outlet position is lower, after its diffusion very easily near people's breathing zone height, so physically and mentally healthy very harmful to the people, particularly commercialization and load-carrying vehicle, this two classes vehicle mainly adopts diesel motor.The used fuel performance of engine, component are depended in the generation of motor vehicle exhaust gases.Most of commercializations of present stage and load-carrying vehicle diesel engine, because the diesel oil chemical composition is quite complicated, flame is stable inadequately, thoroughly when burning, particulate in the waste gas of being discharged, black smoke, oxynitrides content are very high, and environment has been caused severe contamination.In order to solve diesel engine vent gas black smoke problem better, each industrial power of the world is all taking various technique means to promote the innovation and the development of diesel technology, as improve the operating pressure of diesel injector, adopt the above high pressure of 200Mpa, update firing system, adopt advanced design to lower oil consumption, increase electrical control system or the like.But, the poor effect that these technical measures have, have not conform to reality or cost very high and can't effectively be applied.
The purpose of this invention is to provide a kind of diesel engine vent gas that can reduce fully, effectively and pollute, the with low cost and clean fuel special for diesel engine that is easy to apply.
For reaching above-mentioned purpose, clean fuel special for diesel engine provided by the invention, its composition are main raw material with the pentane, and wherein each components contents (weight) is: pentane 50～95%, diesel oil 5～50%.Component concentration of the present invention (weight) is preferably: pentane 70～90%, diesel oil 10～30%.Best composition content of the present invention (weight) is: pentane 70%, diesel oil 30%.
Compared with prior art, the present invention has following characteristics: (1) can reduce tail gas pollution fully effectively.In the molecular structure of fuel element of the present invention, carbon atom all is that covalent single bond links, and the atom valency of carbon is all saturated by hydrogen atom institute, and stability of characteristics belongs to stable hydrocarbon.Pentane accounts for more than 50% in the fuel component, the molecular weight of pentane is little, simple in structure, viscosity is little, and coefficient of surface tension is low, easily gasification, diesel combustion is indoor can be with molecular form and oxygen molecule uniform distribution, flame stabilization, thorough when therefore burning, nitrogen protoxide, black smoke decline to a great extent during exhaust, and the FSN value is below 0.5.(2) economic performance is good.Because the resource utilization of current pentane is extremely low, belong to the petrochemical industry byproduct, and price is low than diesel oil, again because of himself physical property, the present invention and general diesel oil and existing improved products are compared, can reduce production costs, and can effectively reduce the oil consumption of motor vehicle.(3) be easy to promote the use of.Because pentane is liquid under normal temperature, normal pressure, physicochemical property and high-grade gasoline are suitable, therefore aspect transportation, the storage and bring great convenience in the use, existing filling station system is slightly suitably adjusted and can be used, need not reconstruct fueling system, create advantageous conditions promoting the use of clean fuel.
The salient features that following table has provided clean fuel special for diesel engine of the present invention and other fuel compares.
