Abstract
The invention relates to an energy-saving cooling fluid which takes glycol as a base material, and has the following components according to mass percentage: 92 to 95 of the glycol, 1 to 3 of deionized water, 0.5 to 1.5 of decanedioic acid, 0.6 to 2 of n-octanoic acid, 0.4 to 1.5 of potassium hydroxide, and 0.3 to 0.8 of methenamine. The cooling fluid has low freezing point, wide boiling spread, excellent heat conductivility at high temperature, and energy-saving efficiency, prevents frozen injury and occurrence of steam blocking layer when the engine works, improves the thermal equilibrium temperature when the engine works, with the fuel completely combusted, reduces tail gas discharge, and obviously promotes the power.
Description
One, technical field
The present invention relates to the cooling fluid of a kind of motor car engine (engine) usefulness, specifically a kind of energy-conservation cooling fluid.
Two, background technology
It is water mostly that present all vehicles use products such as deicing fluid, cooling fluid basically.The characteristics of deicing fluid are cheap but corrodibility is very big, and all need change every year; The time limit of service of cooling fluid is 2 years, and on the high side have corrodibility simultaneously, and inner water route of time one long hair motivation and water tank all can be because of corrosion damage, though water easily get use long-time after, can make engine interior produce a large amount of incrustation scales, thereby stop up the water route.Above cooling media can make a large amount of engines produce high temperature duration of service after the length, and then damages engine.
Three, summary of the invention
The present invention aims to provide the energy-conservation cooling fluid that a kind of car engine is used, and technical problem to be solved is that long-time use can not damage engine.
Technical scheme of the present invention is to be base-material with ethylene glycol, comprises following components by mass percentage:
Ethylene glycol 92～95%
Deionized water 1～3%
Sebacic acid 0.5～1.5%
N-caprylic acid 0.6～2%
Potassium hydroxide 0.4～1.5%
Hexamethylenetetramine 0.3～0.8%.
The preparation method of this cooling fluid is as follows:
Ethylene glycol is joined in the reactor, stir, add sebacic acid, n-caprylic acid, be heated to 80～100 ℃.Be incubated 30 minutes, get transparent liquid.Potassium hydroxide is dissolved in the deionization, slowly joins in the solution, make the pH value of solution value reach 7.5～8.5.Add hexamethylenetetramine (urotropine) at last, cooling.
This cooling fluid is base-material with ethylene glycol, and all glycols cooling fluids are at high temperature moved, and continuous oxidation and acidifying process are all arranged.The corrosion inhibition of metal is to be achieved in corresponding pH value scope.So the glycols cooling fluid all has certain life-span, this cooling fluid has been added a kind of auxiliary agent: hexamethylenetetramine, even the pH value that makes this cooling fluid under 4.5 situation, each metalloid still can well be protected.This cooling fluid is applicable to all internal combustion engines, does not need in 800,000 kilometers or 10 years of the expendables to change.
This cooling fluid freezing point low (40 ℃), when freezing point and following temperature thereof are solidified, volumetric shrinkage, bad cylinder body can not expand.Boiling point height (170～180 ℃), thermal conductivity is the strongest in the boiling point interval range, more helps heat exchange, engine is operated under the higher temperature, and can draw bad cylinder body.Improve 5-15 ℃ of engine thermal equilibrium temperature, have the raising fuel efficiency, reduce the effect of carbon deposit and maintenance engine.Improved the safety performance of engine greatly.
The size of fuel efficiency is that can fuel oil fully burning in engine.The high boiling point characteristic of this cooling fluid has promoted the working temperature of engine and superpower thermal equilibrium ability, provides safe optimal working temp environment to engine.Make oil inflame more complete.Same oil consumption can produce more power, can guarantee to reduce about oil consumption 3%-5%, and this is one of mechanism of saving fuel oil.
In order to prevent the too high injury that causes of engine temperature, present engine all is equipped with the too high protection mechanism of temperature, and when engine temperature reaches capacity, protection mechanism just can move:---to making ignition lag,---power descends,---temperature reduces.This is to be cost with consumption of power and oil consumption, the purpose of the temperature that is reduced.This is the means of the passiveness of doing something against one's will.This cooling fluid has the automatic thermal balance design of hommization, has the function of low temperature heat accumulation and high temperature heat radiation.When engine temperature is high, cooling fluid high boiling point characteristic, " complex reaction " principle is used.During (complex reacts promptly: liquid is the strongest at the interval heat conductivility of ebullient nearly) engine high temperature, the high boiling point characteristic of cooling fluid has been eliminated the steam resistance layer, and effective heat exchanger effectiveness is taken engine high temperature out of and distributed.Prevent the work of engine securing system, make engine remain optimum Working.Under heavy loading, high temperature, the high and cold severe environment, powerful is lasting, and is unattenuated.This be save fuel oil mechanism two.
The oil cooling The Application of Technology, balanced heat radiation, the cylinder cap temperature greatly reduces, and has eliminated the formidable enemy " overheated summit " of engine, makes the working temperature interval of engine greatly reduce.Dwindling of cylinder bottom and cylinder cap temperature head, cylinder bottom sump temperature slightly improves, and the temperature of machine oil also and then improves, and the raising of oil temperature has reduced a level number corresponding to the viscosity of lubricating oil.The practice at home and abroad empirical evidence: in hydrodynamic lubrication region, the lubricating oil viscosity whenever differs the 1mm2./s. energy consumption and differs 0.5%-1% approximately; Viscosity differs a level number, and then energy consumption differs 1%-5%; Engine temperature improves about 10 ℃, and lubricity can not descend, and the reduction of viscosity reduces oil consumption on the contrary.It is the concrete manifestation of Saving Energy by Lubrication.This is to use " gentle " cooling fluid, three of the mechanism of saving fuel oil.
The design of this cooling fluid has temperature variant viscosity index, that is: below 100 ℃, it is slow to dispel the heat, and this characteristic very helps cold start.For fast warm engine, when engine did not reach working temperature, Automobile Design now was that thermostat is not opened, and electric fan does not change.All be for fast warm engine, and the cooling media of cooling system is selected this cooling fluid, will shorten the warm engine time equally greatly, this is to save four of fuel oil mechanism.
Four, embodiment
Non-limiting examples is described below:
Get in ethylene glycol 94kg, sebacic acid 1kg, the n-caprylic acid 1.2kg input modulation kettle, open stirring and be warming up to 85～95 ℃, be incubated half an hour; Get the stirring of potassium hydroxide 1kg and deionized water 2.2kg preparation potassium hydroxide solution and drop in the modulation kettle down, add urotropine 0.6kg at last to stir postcooling promptly cooling fluid pH value 7.8～8.2.
