1.2. 295700-4410 Diesel Injection Application Scenarios
Common rail system is an oil supply method refers to the Fuel oil from the fuel tank sucked out by the gear pump through the oil-water separator and the gear pump to Fuel fine filter, high-pressure pump, common rail pipe, and diesel injection, all together with the closed-loop fuel supply system composed of sensors and ECU that completely separates the generation of injection pressure and the injection process from each other.

1.3. Reasons for 295700-4410 Diesel Injection Not Working Normally
- There is air in the oil circuit of the engine fuel system.
- Vehicle oil pump oil supply system is not normal.
- Engine common rail system oil leakage or pressure limiting valve is damaged.
- There is a short circuit, cutting out and poor contact in the wiring harness connected to the diesel injection of the vehicle.
- The long-term placement of the diesel injection causes the anti-rust oil to solidify, and the internal components are stuck or the oil holes are blocked.
- Before installing, carefully check whether other components in the common rail system except the diesel injections are damaged so as to prevent the diesel injection from not working properly after being replaced.
1.4. 295700-4410 Diesel Injection Storage Standard
- Choose a Suitable Storage Place
The warehouse and cargo yard where the diesel injection is stored should be kept clean and dry, and away from the factory buildings that generate harmful gases and dust; do not mix with acid, alkali, salt and other substances; the storage place should have a good drainage system; the cargo yard should be flattened with gravel or furnace ash etc. to enhance the water permeability of the surface layer to keep the reservoir area dry.
- Strict Requirements of Warehousing
Strict inspections should be carried out when the diesel injections are put into storage, the surface cleaning work should be done well to remove water traces, oil stains, ash and other dirt, remove the rust and do anti-rust treatment in time. Packaged diesel injections must be protected from damage.
- Keep the warehouse dry and preventing moisture
The relative humidity is usually below 70% for the diesel injections placed in the room, and the corrosion of the diesel injections is significantly reduced.
Diesel injections must be stored in the warehouse, and they are forbidden to store in the same warehouse with commodities with high water content.
After the diesel injection is exposed to rain, the corrosion rate will increase significantly. The purpose of sealing is to isolate the diesel injection from rainwater and humid air, so the warehouse window should be checked in time to avoid rainwater entering the warehouse.
If the diesel injection package is damaged, it should be repaired or replaced; when the package is damp, the packaging material should be dried; if the original anti-corrosion and oil applied at the factory is found to be damaged or dried up, it should be cleaned and re-applied oil in time.
- It is forbidden to leave the diesel injection exposed in the air for a long time.
- It is forbidden to store acid, alkali, salt and other substances together with the diesel injection.
- The unpacked diesel injection must be rust-proof during secondary storage.
