Problems solved by technology

In addition, the concentration of toxic and harmful gases in the exhaust of diesel engines is too high, which may easily cause the concentration of harmful gases to exceed the standard in some areas of the coal mine, which will bring greater pressure to the management of underground ventilation, and may even affect the normal operation of underground operations in severe cases.

Abstract

The invention discloses a composite diesel oil additive and special diesel oil for mining machinery, which is prepared by adding the composite diesel oil additive into diesel oil and coal-based Fischer-Tropsch synthetic oil which are blended according to a certain ratio and carrying out further blending. The invention also discloses an application and a production method of the special diesel oilfor mining machinery. The composite diesel oil additive disclosed by the invention is simple in formula, and the addition amount does not exceed 2% of the mass of diesel. A diesel oil product added with the composite diesel oil additive is water white in color, high in cetane number and oxidation stability, low in sulfur content and acidity and low in NOx, CO, HC and PM in combustion tail gas, andcan be used as special diesel oil for mining machinery.

Description

technical field [0001] The invention belongs to the technical field of engine fuels, and in particular relates to a composite diesel additive, a special diesel product for mining machinery containing the composite diesel additive, and an application and production method thereof. The special diesel for mining machinery described in the invention is especially suitable for application as special diesel for coal mine underground diesel engines. Background technique [0002] Explosion-proof diesel engines have the advantages of high thermal efficiency and high engine power per unit mass. They are favored by major enterprises and help China's coal mining industry to develop rapidly. The underground trackless transportation equipment with explosion-proof diesel engine as the main power source has been more and more widely used due to its obvious advantages such as good underground adaptability, safety, quickness, flexibility, no need to drag cables, and long-distance and long-ter...
