Problems solved by technology
However, the voltage after its series connection just intensifies the electrochemical corrosion in the fuel tank, and the viscous colloidal liquid precipitated will inevitably block the fuel filter and the fuel injector of the original car.
[0005] At present, the working life of the fuel pump of gasoline vehicles is more than 8000h, but the methanol pump is far from meeting the requirements of use

Embodiment Construction
[0011] The present invention is a kind of methanol pump (the content above M60 fully refers to the present invention, the result of the fuel of M85 is almost the same as the present invention, so the scope of application of the present invention is especially above M60, because the electrochemical corrosion of methanol exceeds ethanol, so the present invention In terms of application, it is completely suitable for the application of the working power supply of ethanol fuel (grade E65 or above), so it can also be called ethanol pump), based on the discovery that after passing a DC voltage of 13V or more in methanol, methanol will produce extreme power in about ten hours. Strong decomposition, the color changes from watery transparent to the color of strong tea water, and the monopole appears obvious blue (should be divalent copper ions); from this mechanism, it can be considered that methanol has pumped copper at a voltage above 13V. Cords and power connectors produce extremely ...

The invention discloses a method for setting an alcohol type fuel motor-driven pump, wherein the method is applied to the alcohol type fuel motor-driven pump and is used for setting the working voltage of the motor-driven pump to be 6-10.4V. The method is particularly applied to the alcohol type fuel motor-driven pump with the output direct-current working voltage being 7-9V or being more than 9V and smaller than 10.4V. In the alcohol type fuel motor-driven pump, the turn number of a rotor winding of a driving motor is intentionally reduced by 15-50%. According to the invention, the corrosion to the pump due to electrochemical reaction during working can be greatly reduced, the service life of a fuel pump with adoption of the working voltage, such as 8-8.9V, can completely meet the operating requirements of the engine, and the defect of blocking a filter and an oil nozzle can be basically eliminated.
Description
technical field [0001] The invention relates to a fuel supply method and device for a methanol engine, in particular to a method and a device for setting a built-in fuel pump. Background technique [0002] The built-in fuel pump is the driving force for the fuel supply of the vehicle in the EFI system. On July 2, 2009, the National Standardization Management Committee announced that the "Methanol Gasoline for Vehicles (M85)" standard was officially approved for promulgation and implementation. It is understood that this standard is the first product standard for methanol gasoline. Methanol gasoline (such as M85, above M60) or single pure methanol (M100) is an economical fuel to replace gasoline. Methanol gasoline or single pure methanol and another kind of alcohol fuel (ethanol gasoline) can be completely used in existing automobile engines use. That is to say, existing cars can be driven by a single methanol fuel, and only use a small amount of gasoline to start combusti...
