Fuel system of special equipment: what is important to know and how to choose spare parts

The fuel system is one of the key components of any special equipment, determining its power, efficiency and durability. Not only fuel consumption, but also the overall productivity of machines, especially those used in difficult operating conditions: in quarries, construction, agriculture or industry, depends on the correct operation of the fuel system.

The main components of the fuel system are:

1. Fuel pump (high-pressure fuel pump PNVT, or low-pressure fuel pump PNNT), which is responsible for supplying fuel
2. Fuel injectors - provide precise dosing of fuel into the combustion chamber
3. Fuel filter - is responsible for cleaning fuel from water or mechanical impurities
4. Plunger - ensures the creation of high pressure
5. Fuel rail - responsible for fuel distribution
6. Shut-off valve - responsible for stable system operation, without leaks and pressure drops
7. Temperature sensors and fuel pressure sensors - adjust fuel supply and injection for stable engine operation in various conditions, and also adjust the temperature regime
8. Injector nozzles - providing fine and uniform atomization of diesel fuel - are one of the most important components
9. Oil seals - prevent fuel leakage and air ingress into joints and rotating parts
10. Plain bearings - are responsible for absorbing loads and maintaining the correct axis of rotation
11. The cage - acts as a support element and ensures the correct position of the bearings

One of the typical problems with the fuel system is wear of parts.

During intensive operation, the entire fuel system is subjected to high loads, which leads to damage and wear of its elements.

The most common malfunctions:

1. Pressure drop in the system due to pump failure
2. Leaks in fuel lines
3. Contamination of injectors and filters
4. Electronics and sensor malfunctions

Such breakdowns cause increased fuel loss, general instability in engine operation, or even a complete stop of the equipment.

How to choose spare parts for the fuel system of special equipment?

When choosing spare parts, it is very important to consider the following factors:

1. Originality - it is better to give preference to original fuel system spare parts to avoid repeated breakdowns
2. Compatibility - you must be sure that you have selected the exact part that fits your specific model of equipment (by serial number or brand)
3. Source of purchase: buy fuel system parts only from trusted suppliers who specialize in fuel systems, have good experience and are specialists who can select the necessary parts by engine number, or according to the table, or part marking.
