The core function of a diesel fuel tank is to provide safe, stable and continuous fuel storage and supply for diesel engines. It is an indispensable key component in diesel power systems. Its specific core functions can be elaborated in detail from the following aspects:
1. Fuel storage
This is the most basic and core function of a diesel fuel tank. It can store a certain amount of diesel according to the fuel consumption requirements of equipment (such as cars, trucks, generators, ships, etc.) to ensure that the engine can maintain normal operation for a period of time without external fuel supply. For example, the large-capacity fuel tank of a long-distance freight truck can support the vehicle to travel thousands of kilometers and reduce the number of refueling in the middle.
2. Fuel protection
The fuel tank provides a relatively closed environment for diesel, which can effectively protect the fuel from external contamination.
Prevent impurities such as dust, sand, and moisture from entering the fuel, and prevent these impurities from clogging the engine fuel pipeline, fuel injector and other precision parts, thereby reducing engine failures.
Some fuel tanks are also designed with ventilation devices, which can not only balance the air pressure inside and outside the tank (avoid vacuum or excessive pressure when fuel is filled or consumed), but also filter the air entering the tank to further improve the cleanliness of the fuel.
3. Stable fuel supply
The structural design of the fuel tank (such as the built-in fuel pump, the position of the fuel suction pipe, etc.) helps to ensure that the fuel is stably delivered to the engine. For example, the bottom of the fuel tank is usually designed to be inclined or grooved to ensure that when the fuel volume is low, the fuel can be concentrated near the fuel suction port to avoid the engine from stalling due to insufficient fuel supply. In addition, some fuel tanks are also equipped with fuel filters (or integrated with filters) to filter the fuel again before it enters the engine to improve the fuel supply quality.
