Methanol gasoline

Provided is methanol gasoline. The invention relates to the technical field of energy, and specifically relates to a methanol gasoline formula. The methanol gasoline formula includes adding a methanol gasoline compound additive to methanol by weight ratio of 0.05% for denaturation, and mixing 15-65 parts of methanol, 20-30 parts of 90 # gasoline, 10-30 parts of light aromatic hydrocarbons, and 10 parts of naphtha by weight after denaturation. The methanol gasoline is good in corrosion resistance, and generates chemical and physical adsorption to resist corrosion by inhibiting basic groups of molecules. The methanol gasoline is powerful in dynamic property, high in octane value, good in antiknock property, low in fuel consumption, and safe and reliable in use. The method makes alcohol and gasoline dissolve organically, and helps to enhance the stability without delamination and emulsification. The methanol gasoline can be used with ordinary gasoline by mixing or crossing. By using the methanol gasoline, motors are easy to start under the low temperature condition of -35 DEG C, and have no air resistance at high temperature, thereby being started normally. The methanol gasoline is suitable for gasoline and liquid fuels, and can help to save 10-25% of the fuel oil, to reduce the amount of smoke and exhaust gases, and to reduce pollution.

Oil supply type compressor

The objective of the present invention is to reduce the pressure reduction time while preventing foaming in an oil separation device during capacity control of a compressor, and to avoid startup congestion and thus enable normal starting even when a portion provided in an air release pipe and having a small flow path cross-sectional area becomes clogged. This oil supply type compressor is equipped with a compressor main body, an oil separation device, and an air discharge passage for discharging compressed air during capacity control of the compressor. Furthermore, the air discharge passage is equipped with a passage having a large flow volume and a passage having a small flow volume, and when compressed air is discharged from the air discharge passage to the atmosphere during capacity control, the pressure in the oil separation device is discharged using the passage having a large flow volume, until the pressure reaches or falls below a restarting-possible pressure, which is the pressure at which startup congestion does not occur when the compressor main body is restarted. When the pressure in the oil separation device reaches a prescribed pressure, which is less than or equal to the restarting-possible pressure and is higher than a foaming pressure, which is the pressure at which foaming occurs when the pressure in the oil separation device is discharged quickly, the pressure is discharged using the passage having a small flow volume.
