Four key points for diesel engine seasonal change

1, change the oil

Due to the large number of diesel engine types, specifications and models, and the requirements of the used oil are not consistent, two kinds of replacement methods are proposed: (1) If there is no explicit requirement for oil in the diesel manual, or if there is no “winter or summer” distinction, it shall be When the diesel engine is hot or after the operation is completed, the water temperature is about 80 degrees, and the engine oil is released. The oil is precipitated for not less than 24 hours and then used again. Precipitated oil base should be drained and new oil should be added when the amount of oil is insufficient. 2 In the diesel manual, if there is winter or summer oil, the engine oil should be replaced and used. The method is: to make the water temperature of the diesel engine reach eighty degrees, and then put the engine oil on hot oil (be careful not to burn hands). Wait 30 minutes, tighten the drain plug, add the same amount of diesel oil to the oil pan, and run at medium speed for 1 to 2 minutes. The cleaned diesel oil will be released and used for washing. In this way, the oil can be drained and cleaned, and the oil passage can be unimpeded, which creates the conditions for the fault-free operation of the lubricant. Add summer oil.

2, hygiene cleaning

Remove the insulation and clean the machine. Clean dirt, debris, grease, and wash your face thoroughly. During the process of cleaning, cleaning and cleaning, loose nuts, rivets, and defects on the exterior can be found and replaced and repaired.

3, cleaning three filters, three nets

Air filters, diesel filters, and oil filters are commonly referred to as triple filters. The main points of attention when cleaning the three filters are: 1 The three-filter is a paper filter, and it is best to replace the new ones with the exception that the air filter is available after cleaning. 2 Metal filters, filter elements, can only be cleaned with clean oil, brush or gas cylinder, use gas to blow out dirt, must not be fired. "Triple-net" refers to the filter of diesel filling port, oil filling port, and exhaust gas outlet, and should be thoroughly cleaned to ensure smooth access.

4, rotating oil indicator

Any diesel engine engraved with the "Winter and Summer" rotation indicator in the lubricating oil circuit (generally installed at the filter) should be rotated to point to the word "summer" in order to realize a large oil circulation. In this way, the oil temperature can be effectively avoided and the oil pressure can be reduced and the wear of the machine parts can be reduced.

Why choose aspheric lens?
Aspherical Lens is a single optical component with one or two aspheric surfaces. An aspheric lens or asphere is a lens whose surface profiles are not portions of a sphere or cylinder. As optical systems are pushed to be better, faster, and cheaper, it becomes necessary to explore aspheric solutions. Aspherical elements eliminate monochromatic aberrations (e.g. spherical aberration) and improve focusing and collimating accuracy. The whole system will be smaller and lighter, and possibly cheaper than the multi-lens design. 

Our aspheric lenses are made by grinding & polishing. So they are more precise than traditional mould pressed. And also the tooling cost for grinding & polishign would be cheap and small quantity order would be accept.
