The invention relates to a carbon cloth load nickel oxide coated iron oxide nanorod composite material and a preparation method thereof. Iron oxide nanorods are loaded on the surface of carbon cloth, the diameters of the iron oxide nanorods are 60 to 80 nm, the lengths of the iron oxide nanorods are 400 to 600 nm, and the thickness of dendritic nickel oxide coated on the surfaces of the nanorods is 2 to 100 nm. The iron oxide nanorods are uniformly loaded on the surface of carbon cloth by using a hydrothermal method with simple technology and controllable experiment parameters, a dendritic nickel oxide nano-structure is synthesized on the surface of iron oxide by using a secondary hydrothermal method, and the coated dendritic structure can improve the electrical conductivity of the iron oxide nanorods but cannot influence the contact of the internal nanorod-shaped iron oxide structure and an electrolyte so as to realize a synergistic effect of the internal nanorod-shaped iron oxide structure and the electrolyte preferably. The structure has large specific surface area and high porosity, the contact area with the electrode can be further increased, and then the circulation and multiplying power performance are improved.

The invention discloses methanol gasoline. The methanol gasoline is prepared from the following components in percentage by mass: 60-70% of methanol, 6-7% of aromatic hydrocarbon, 40-46% of naphtha, 0.004-0.0043% of sodium hydroxide, 0.3-0.33% of corrosion inhibitors, 0.2-0.23% of antioxidants, 0.5-0.53% of lubricants and 2-2.2% of stabilizers. The methanol gasoline has the following beneficial effects: (1) additives adopt raw materials with abundant sources, stable performance and clean emission after combustion, the mixing process is simple, the production cost is low, and the production process is free emission of three wastes; (2) the environment can be effectively protected, the fuel cost can be reduced, and the petroleum resource can be saved; and (3) the methanol gasoline has good protection effects on power systems and oil supply systems of vehicles. Actual test and inspection of the methanol gasoline show that power performance, lubrication performance, corrosion resistance, oxidation resistance, low-temperature ignition and oil consumption of the methanol gasoline are superior to that of 92# national 5 standard gasoline. The methanol gasoline fuel is simple in composition, wide in raw material resources, low in production cost, high in combustion performance, long in storage time, free of stratification and free of deterioration, and is worth of mass production, popularization and application.

The invention provides a method and a device for controlling the power assisting function of a vehicle. The method comprises the steps that a current working mode fed back by a vehicle control unit is obtained; the working modes comprise a pure electric mode, a traditional mode and a hybrid mode; if the obtained working mode is a traditional mode or a hybrid mode, a dynamic power assisting function is executed, and the execution of the dynamic power assisting function comprises the steps that a motor dynamic power assisting torque demand is sent to a motor, and an actual motor dynamic power assisting torque returned by the motor is received; and the power performance of the engine is compensated according to the actual dynamic power-assisted torque of the motor. According to the dynamic torque compensation method, device, the whole vehicle controller controls the motor with the fast response to conduct dynamic torque compensation, the whole vehicle requirement can be met in a short time, the whole vehicle acceleration performance is improved, and the driving feeling is improved.

The invention provides a vehicle-used methanol gasoline clean fuel, which not only comprises methanol, but also ethanol and additive so as to form a methanol and ethanol gasoline clean fuel. The clean fuel comprises low mixture ratio, medium mixture ratio and high mixture ratio in volume by weight. The invention also discloses a preparation method of the clean fuel: mixing the methanol, the ethanol, the addictive and the gasoline; according to three ratios, the steps are as follows: step 1, measuring the methanol and the ethanol and adding into a measuring cylinder; step 2, adding the addictive into the mixed liquid according to the mixture ratio, and stirring the mixture to be evenly mixed; and step 3, adding gasoline into the mixed liquid according to the mixed ratio, and stirring the mixed liquid again to be evenly mixed. The vehicle-used methanol gasoline clean fuel effectively improves the stability of mixed fuel, reduces the layering temperature of the system, makes up the defect that the methanol is limited by the raw materials by using rich methanol source, can be mixed according to three proportions, can ensure that the power performance is as same as the gasoline car, and obviously improves the pollutant emission.
