The operating current of thick-film resistor fuel level sensor is generally the mA of several mA~hundreds of, and operating voltage is 0~12V, work
It is equivalent to a variable potentiometer as principle, when thick-film resistor is high resistance, operating voltage just increases, on the contrary then reduce.
Fig. 2 and Fig. 3 is to breathe out the Song Hua River minicar for flying to produce to travel using the automobile-used high-clean gasolines of M80 in embodiment 3
After 10000 kilometers, the platinum resistance of the 678201 thick-film resistor fuel level sensor of model of Ruian Chuan Chi motor vehicle fittings factory production
Situation of change.As can be seen from the figure：The anode plate face and anode contact of thick-film resistor are passivated by methanol gasoline preservative,
Its metalwork, rubber parts and plastic part do not change, are detected with multimeter：Circuit each point is logical.
Fig. 4 and Fig. 5 is that figure is the methanol and 93# national standards that the thick mould resistance of model 678201 is 80% in usual methanol content
Gasoline configuration usual methanol clean gasoline laboratory lead to 12V DC electricity 6 hours after situation of change.Fig. 4 platinum resistance is
Blackening corrosion is bad, and the contact of Fig. 5 resistance is corroded, and supply lines falls off.The anode plate face of platinum resistance is burnt, and is detected with multimeter：
Circuit is obstructed.
It is the automobile-used high-clean gasolines of M80 of 678201 thick mould resistance in embodiment 3 in reality that Fig. 6 and Fig. 7, which is the upper figure number of being,
It tests room and leads to situation of change of the 12V DC electricity after 120 hours.Fig. 6 can be seen that the platinum resistance still bright blackening that is not corroded, figure
7 it can be seen that wiring electric shock still falls off with connected be not corroded of wiring.Platinum resistance anode plate face and anode contact are by methanol
Gasoline preservative is passivated；It is detected with multimeter：Circuit each point is logical.

There are various metals component, the antiseptic properties such as pump case, armature laminate patch and electrical plug bad in electric fuel punp
The substances such as the formic acid that methanol gasoline is generated due to oxidation have corrosivity to metals such as copper, aluminium, magnesium and zinc, lead to methanol vapor
It on the one hand can accelerate the abrasion of pump body portion containing the corrosion products such as a large amount of positive metal ions, corrosion product in oil, separately
On the one hand it is readily adsorbed in the negative terminal surface of carbon brush, makes carbon brush and commutator poor contact, leads to the decline of pump speed, the pump housing
Abrasion and the lower general who has surrendered of pump revolution reduce the working efficiency of pump and shorten the service life of pump, while corrosivity product will
Cause fuel oil filter to block, makes vehicle can not normally travel.
Fig. 9 and Figure 10 is to breathe out the Song Hua River minicar for flying to produce to travel using the automobile-used high-clean gasolines of M80 in embodiment 3
After 50000 kilometers, the situation of change of fuel filter net, Fig. 9 fuel screens surface is totally miscellaneous without adsorbing the metal of any corrosion
Matter, Figure 10 illustrate that the fixed plastics part of oil pump is intact without there is corrosion swelling set, illustrate that M80 Vehicular methanol petrols are using
In without generate corrosion product.
Figure 11 and Figure 12 is to breathe out the Song Hua River minicar for flying to produce to use the automobile-used high-clean gasoline rows of M80 in embodiment 3
After sailing 50000 kilometers, the situation of change of electric pump inserted sheet.It can be seen that from figure：Electric pump anode tab is by methanol gasoline preservative
Passivation, does not occur corrosion phenomenon.
Methanol molecules amount is small, and molecular structure is simple, is easier to penetrate into the non-metal workpieces such as plastics, rubber than gasoline,
Plastics and rubber part are made to be swollen.When the methanol ratio in methanol gasoline is less than 15%, negligible methanol gasoline is to oil pump
In influenced for the swelling of the resinous material and adhesive material for sealing of insulation；When the methanol ratio in methanol gasoline is big
When 15%, after the resinous material of the insulation used in oil pump armature and the adhesive material for sealing are swollen by methanol gasoline
Being easy to fall off causes to block fuel system, influences the normal work of electric pump.
