Benefits of technology

[0008] An object of the present invention consists in providing a novel fuel oil additive having effects on improving the quality of oils, lowering the oil consumption, decreasing carbon deposit and redu-cing harmful substances in tail gas of automobile and smoke dust of oil burning boiler as well as reducing abrasion and corrosion of parts of engine.

Problems solved by technology

In order to produce a high-octane number gasoline, one method is the improvement of petroleum refining technology by means of catalytic cracking, alkylation, platinum reforming, or the like, but the technological improvement is limited by a variety of factors, including reform and renovation of equipments, funds, a complete set of techniques, and so on; and another method is the addition of a suitable antiknock agent into gasoline.
It has been found in uses that the former is unfavorable to the storage of oils, and the latter results in abrasion of engine and causes new environmental pollution.
Problems common to these antiknock agents are low effectiveness, large amount, and diseconomy and inconvenience.
Tetraethyl lead used for many years has been prohibited because of the toxicity of lead.
Among these compounds, ferrocene has been prohibited because of a harmful effect on engine, the manganese-base antiknock agents have been limited and prohibited because of its poisonous effect on human nerves and environment, and complexes of cerium and .A-inverted., -diones have a too high cost to popularize.

Description

[0001] The present invention relates to an improvement of fuel oil performance, and particularly to a fuel oil additive capable of effectively improving the combustion performance of fuel oils in a combustion chamber of automobile and an oil burning boiler and having energy-saving, decontamination and antifriction effects, and the present invention also relates to fuel oil products added to this kind of additive. This invention particularly relates to a gasoline antiknock additive and a gasoline product containing the antiknock additive.[0002] The combustion performance in a combustion chamber of automobile and an oil burning boiler is one of important performance indexes, and it determines whether a fuel oil has properties of energy-saving, environment protection, and the like. For a gasoline product, an important performance index is the antiknock property, and its antiknock index is generally expressed as the average value of an octane number determined by research method (RON) a...
