Description
One, technical field:
The utility model relates to a kind of automobile double Fuel Control System, particularly a kind of new-energy automobile methyl alcohol and gasoline dual-fuel control system.
Two, background technique:
Current methanol vehicle field major technique is presented as single methanol vehicle control unit, name is called " the free fuel control unit of FFV ", its effect just changes former car computer system fuel injection quantity parameter, the necessity of not making system principle and mechanical position changes, popularization exists wretched insufficiency for the methanol vehicle large size, because the monotony of system, subject matter shows as the corrosivity of methyl alcohol to the many positions of former car, swellability can't solve, for example, corrosion to former car electronic fuel pump and fuel level sensor, swelling to each rubber parts, and because there is the cold start-up difficulty in triangular web, cold reception heat difficulty, and when running into fault, do not have standby system and under certain environment, have to and gasoline is mixed and burnt the oil circuit that causes and stop up.Low temperature can not start, promptly use extraordinary mode cold-starting to get up since the methyl alcohol boiling point low cause discharging not up to standard and to cylinder body too much infringement cause vehicle frequent fault to occur.Laboratory data proves the road of can not running away, reduce engine life, can not cruising in addition the time the bad pump on the way of being everlasting, stop up oil circuit and make the oil pump feed deficiency, motor is undesired, do not know that many serious problems such as Fuel Oil Remaining cause methanol vehicle to have wretched insufficiency.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of new-energy automobile methyl alcohol and gasoline dual-fuel control system are provided, and no longer includes fault thereby reach methanol vehicle, safety, energy-conservation, simple to operate, prolong engine life, raise the efficiency etc.
Its technological scheme is: mainly be made up of methanol fuel system and Fuel Petroleum system, described methanol fuel system mainly is made up of corrosion-resistant fuel tank, corrosion-resistant methanol line, corrosion-resistant external oil pump, corrosion-resistant directional valve, air intake branch, corrosion-resistant return pressure valve, ECO control unit, corrosion-resistant fuel level sensor and circuit, corrosion-resistant fuel tank is communicated with motor by corrosion-resistant methanol line, main line, and corrosion-resistant external oil pump is set in the corrosion-resistant methanol line; Described Fuel Petroleum system mainly is made up of medium gasoline pipeline, Fuel Petroleum case, and the Fuel Petroleum case is communicated with main line and motor by medium gasoline pipeline, corrosion-resistant directional valve.
Above-mentioned corrosion-resistant methanol line is provided with corrosion-resistant filter, and is provided with corrosion-resistant return pressure valve on the loop of corrosion-resistant methanol line.
Be provided with corrosion-resistant fuel level sensor and circuit in the above-mentioned corrosion-resistant fuel tank.
Its working principle is: by corrosion-resistant external oil pump the methanol fuel in the corrosion-resistant fuel tank is sent to motor, this moment the engine combustion methanol fuel, stablize oil pressure by corrosion-resistant return pressure valve, threeway connects, unnecessary fuel is got back to corrosion-resistant fuel tank, this moment is by corrosion-resistant directional valve control stopping petrol system work, another methanol fuel system then works, the conversion work principle is to be finished by circuit control by corrosion-resistant return pressure valve of corrosion-resistant external oil pump and corrosion-resistant directional valve mutually, when the cold preheating of needs cold start-up, then open petrol system, the methyl alcohol system closing, conversion is by circuit switch control in the cockpit mutually, and process is simply free, can freely change as required.
The beneficial effects of the utility model are: methanol fuel also belongs to novel energy fuel, the same with other New-type fuel, all has unique property, away from the auxiliary of conventional gasoline fuel be incomplete, and gasoline has had accompanying of methyl alcohol, few minutes of operation all is sufficient combustion and allows the very important effect of oneself having brought into play, be to make something perfect even more perfect, but main effect has solved methyl alcohol, 1: the cold start-up difficulty, especially in the winter time easily finish startup by gasoline, 2, automobile uses methanol fuel not only to make engine emission not up to standard when low temperature, and because the insufficient dynamics of mixing meeting booster engine cylinder wear with the cylinder inner engine oil of the low burning of methyl alcohol boiling point, reduce engine life (laboratory data is arranged), then can avoid this problem with the hot car of gasoline, use methyl alcohol instead behind the hot on the contrary car, because rising to 68 degree back methyl alcohol boiling points, improves engine temperature, the methyl alcohol oxygen content is higher than gasoline in addition, so firing effect surmounts gasoline more, prolong engine life, fully reach energy-conservation, environmental protection, low-carbon (LC), can also maximal efficiency save the fuel of unnecessary waste, reduce fault.3, because this mounting type stores at methanol fuel, improvement on supplying with and filtering, stifled burn into swelling of having cut off methanol fuel to each system of former car.4, article two, the system that works alone is that muddy combustion does not take place two kinds of fuel, and filtration system cleans more, do not stop up for a long time, methanol vehicle is no longer frequently broken down because stop up oil circuit, 5, because fuel is supplied with separately, can use the pure fuel of M100 methyl alcohol for a long time, need not mix gasoline, reduce fuel cost, improve energy-conservation, saving and environment protection effect greatly.
Four, description of drawings:
Accompanying drawing 1 is a worm's eye view of the present utility model;
