In order to ensure the normal operation of the tractor, in addition to the health of the various components of the machine, the selection of diesel oil must also meet certain quality requirements. To meet these requirements, you need to do the following six things:

1, should have good flow properties and atomization properties. That is, there must be a lower cloud point and a pour point (relative to the ambient temperature of use), the viscosity is moderate, and it can ensure good atomization of the oil supply without interruption.

2, good combustion performance, that is, there should be a certain cetane number. Diesel should be able to evaporate quickly in the engine cylinders and ignite at the appropriate temperature and pressure. The burning should be complete and stable, no black smoke, no carbon deposits.

3. Have good stability. The nature is stable, it is not easy to oxidize to form colloid, avoid oil supply failure, and ensure the normal operation of the engine.

4. Non-corrosive. Diesel is required to have low levels of sulfur and sulfides, acids and bases. These materials or their combustion products can cause corrosion to engine parts and containers.

5, the flash point should be high. It is not easy to ignite when exposed to fire during storage and use, so as not to cause fire.

6, should be clean, no mechanical impurities and moisture. (Yizhu)
