Description
Technical field
The present invention relates to a kind of anti-icing fluid, more particularly to a kind of anti-icing fluid on LNG automobiles.
Background technology
Vehicular liquefied natural gas is stored in gas cylinder with the liquid of low temperature and gaseous form, can be with pure liquid form or gas
Liquid mixed form is extracted from gas cylinder, and gaseous state is heated it into by liquified natural gas vaporizer and its pipeline.Vaporization
Device is arranged between gas cylinder and engine.Vaporizer is connected with engine-cooling system, coolant（Engine provides）Flow through vapour
Change device shell side and tube side is heated.When liquefied natural gas enters vaporizer, the high temperature coolant from engine is by its gas
Change and heat, be subsequently fed to engine.
Automobile-used LNG liquefaction points are -161.5 DEG C, and anti-icing fluid big calorimetric is absorbed when gasifying through vaporizer, causes anti-icing fluid in vapour
Change freezed in winter in device, anti-icing fluid is unable to proper flow, influences the normal use of automobile.Therefore, traditional anti-icing fluid resistance to frost
The requirement of LNG heavy trucks cold district is not in the winter time reached.
The content of the invention
For deficiency of the prior art, new there is excellent anti-corrosion, antirust, antiscale, height boiling the invention provides a kind of
Point, low freezing point cold district LNG automobile specifieds anti-icing fluid.
In order to solve the above problems, this kind of LNG motor vehicle antifreeze fluid, it is characterised in that be by following substances in percentage by weight
Composition：
The beneficial effects of the invention are as follows：The LNG automobile engine winterization fluids of the present invention.In traditional ethylene glycol type anti-icing fluid
On the basis of add second of antifreezing agent dimethyl sulfoxide (DMSO), significantly lower anti-icing fluid freezing point, good freezing protection effect, freeze point depression
Amplitude is big, and minimum freezing point as little as -65 DEG C of low temperature, which use, not to freeze.It is good to suppress corrosive effect, it is little to aluminium, steel and iron corrosion.
Additive BTA can improve anti-icing fluid and intermetallic heat conduction velocity, and can slow down the precipitation of rust deposite.
