Abstract
The invention relates to a gasoline detergent which can notably reduce deposited matters in the firebox of the gasoline motor. The detergent includes a high-surfactivity polyether amine, a kind of polyether carrier liquid with excellent oil solubility and functional agents of cosolvent, antioxidant, anti-rust agent, preservative and demulsifier thereof. The weigh percentages of the above components are that polyether amine is 40-50 percent; polyether carrier liquid is 40-50 percent; cosolvent and other functional agents are 5-20 percent. When 250-500ppm dosage of the detergent of the invention is added into the commercial car gasoline, not only the oil nozzle and the air inlet valve in the fuel gas inlet system of the motor of the car can be inhibited and cleaned, but also the deposited matters in the firebox of the gasoline motor can be obviously reduced. The increment of deposited matters of the car gasoline using the detergent of the invention in the firebox can be 70 percent above less than the increment of deposited matters of the car gasoline containing the detergent on the market in the firebox.
Description
Technical field
The present invention relates to a kind of motor spirit purification agent and preparation method thereof.This purification agent with the good polyethers of the polyetheramine of high surface and oil soluble for mainly containing effective constituent.The invention still further relates to the purposes of this purification agent in motor spirit.
Background technology
Along with rapid development of automobile industry, the recoverable amount of China's automobile is increasing sharply.Being accompanied by automobile produces, when life brings convenience, has also strengthened consumption of petroleum resources and tail gas emission of harmful substances to people.How to allow motor car engine be in good work condition state for a long time, fuel gasoline is burnt fully, reduce oil consumption, improve discharging.This just necessarily requires the fuel oil inlet system of motor car engine to keep clean for a long time.For this reason, in the motor spirit that uses, must add gasoline cleaning agent.
Yet, mainly containing effective constituent among disclosed at present motor spirit purification agent such as CN1133873A, CN1167136A, the CN1227866A is polyisobutene succinimide, common PIBA and mineral oil carrier fluid, such gasoline cleaning agent has good keeping a public place clean and cleanup action to petrolic oil nozzle, intake valve, can effectively suppress and clean petrol engine and form carbon distribution at these positions.But such gasoline cleaning agent is brought the carbon distribution that washes down in the fuel oil inlet system into combustion chamber.Usually, during total sedimental standard bench testing, compare, contain such marketable gasolines purification agent, the settling of combustion chamber is obviously increased with the basic motor spirit that does not contain purification agent in implementation evaluation intake valve and combustion chamber.Clearly stipulate to contain the motor spirit of purification agent in motor spirit purification agent GB GB19592-2004, through engine rig test, the total settling in the combustion chamber contrasts basic motor spirit increasing amount must not surpass 40%.At present, the marketable gasolines purification agent that adds in China's motor spirit causes the total settling increasing amount in combustion chamber in the 20-30% level.To this, at US 6,136, existing clear and definite elaboration in 051 patent.
The total settling of gasoline engine combustion chamber significantly increases, the compression ratio of engine is increased, and be difficult for heat radiation, to cause compression end of a period gas temperature rising in the combustion chamber, OR Octane Requirements (ORI) increases, increase the mechanical disturbance between top land and the cylinder cap when serious, produce " carbon engine knock ", will cause that finally engine consumption increases, deterioration of emission.Seek a kind of settling that can suppress and clean the generation of vehicle fuel inlet system, can obviously reduce the total sedimental gasoline cleaning agent of automotive engine combustion chamber technical object of the present invention just again.And gasoline cleaning agent of the present invention can reduce more than 70% at the settling increment of engine chamber than present commercially available gasoline cleaning agent therefore.
Summary of the invention
The purpose of this invention is to provide a kind of gasoline cleaning agent that can remarkably reducing deposit of gasoline engine combustion chamber, this agent not only can improve the quality of motor spirit, make it more abundant in the motor car engine burning, improve thermo-efficiency, produce settling but also can suppress and clean the vehicle fuel inlet system, reduce the total settling of automotive engine combustion chamber significantly.Thereby make motor car engine be in good operation condition state for a long time, reduce oil consumption, reduce the tail gas emission of harmful substances, prolong engine work-ing life.
