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 discloses a hydraulic retarder for small and medium-sized vehicles. The hydraulic retarder for the small and medium-sized vehicles comprises a stator and a rotor; a stator cavity is formed in the stator; the inner side wall of the stator cavity is provided with at least two work oil grooves; work oil cavities are defined by the outer side wall of the rotor and the work oil grooves; each work oil cavity is sequentially divided into a low pressure area and a high pressure area in the rotating direction of the rotor; oil liquid is arranged in the work oil cavities; the oil liquid isadsorbed to the outer side wall of the rotor by being close to the surface layer of the rotor; the rotor drives the oil liquid in the work oil cavities to flow in the circumferential direction of therotor so that the pressure of oil liquid in the high pressure areas can be larger than that of oil liquid in the low pressure areas; the stator is provided with oil supplying channels communicating with the low pressure areas of the work oil cavities; and the inner side wall of the stator is provided with an oil returning groove. The hydraulic retarder for the small and medium-sized vehicles is small in volume, and therefore the hydraulic retarder is applicable to the small and medium-sized vehicles; and the damping force is large, and therefore the hydraulic retarder for the small and medium-sized vehicles can be used under the steep gradient condition.

On a facing surface (12a) of a pad (12) that faces a rotation shaft, an oil supply unit (24) is provided in an end region downstream of the rotation shaft in the rotation direction, and the oil supply unit (24) is formed along part of an isopleth of the pressure distribution on the facing surface (12a) generated by a lubricant being caught between the rotation shaft and the facing surface (12a), said part of the isopleth being downstream, in the rotation direction, of the pressure maximum of the pressure distribution.

The invention provides a lubricating structure for an output shaft of a liquid booster pump. A first eccentric part of the output shaft bears the maximum load in the liquid boosting process; a telescopic piston of an oil feeder is directly pushed and pressed by a second eccentric part to act mainly by means of power of the output shaft; lubricating oil in a round core hole is sucked and is pushed, pressed and fed to a deep oil supplying hole in the output shaft; and the lubricating oil is forced to be discharged out of an oil outlet and then is subjected to cyclic supplementation on the surface of the first eccentric part, so that good lubrication is maintained for a long time when a rotating wheel of a contact plunger rotates on the first eccentric part, and the service life of the output shaft or the rotating wheel is effectively prolonged.

A chain tensioner includes a sleeve fixedly disposed in the cylinder, with one end thereof inserted in the plunger and the other end protruding out of the plunger. A cylindrical space is formed between the outer periphery of the sleeve and the inner periphery of the cylinder. An oil supply passage opens to the cylindrical space. A communication passage is defined in the sleeve and provides communication between the cylindrical space and the reservoir chamber.

The invention provides a lubricating system for a double-stroke gasoline engine which comprises a cylinder, an oil pump and an oil tank. The oil pump is connected with the oil tank by an oil tube. The oil pump is connected with a crank shaft of the double-stroke gasoline engine by a gear pair. The oil pump is connected with an oil dividing box by an oil transportation tube. The oil dividing box is communicated with a plurality of oil holes on the cylinder by a plurality of oil supply tubes. An oil ring is arranged under a gas ring on the periphery of a piston in the cylinder. The oil pump and the gear pair are replaced by a diaphragm pump. An air inlet of the diaphragm pump is communicated with a crank shaft tank of the double-stroke gasoline engine by an air tube. An oil inlet of the diaphragm pump is communicated with the oil tank by the oil tube and an oil outlet is communicated with the oil dividing box by the oil transportation tube. The invention has reasonable structure, overcomes the shortcomings that the discharging effect is inferior due to the oil and gasoline mixture in the prior art, ensures the standard discharge of the double-stroke gasoline engine, and promotes the power and the service life of the double-stroke gasoline engine.
