Introduction of Diesel Engine Fuel Filter and Shock Absorber

Fuel filter assembly (including primary filter)

In order to obtain a fine filter for diesel oil, to prevent the abrasion and corrosion of diesel oil, etc., many precision parts in the fuel supply, in diesel engines, in addition to the precipitation cup (most diesel engines do not have a precipitation cup) Stage filters (small single-cylinder diesel engines are mostly first-stage filters). Diesel primary filters generally have larger filter slots to filter out larger particles of impurities. The diesel fine filter has a small filter gap, and it is necessary to filter out foreign particles that can be harmful to the fuel supply system. After passing through the two-stage filtration, the diesel has become cleaner and then pressed into the fuel injection pump through the fuel transfer pump.

Shock absorber

The main function of the shock absorber is to absorb vibration energy to achieve the purpose of vibration reduction. At present, silicone oil shock absorbers are mainly used in engines. The vibration damping principle of silicone oil shock absorbers is that when resonance occurs, a certain relative displacement occurs between the silicone oil shock absorber housing and the inertia block, and the silicone oil in the gap is affected by shear force As a result, viscous friction torque occurs, thereby absorbing vibration energy to achieve the purpose of vibration reduction.
