Description

Technical Field

[0001] The utility model relates to the technical field of diesel vehicles, in particular to an intelligent diesel management system for preventing diesel from waxing. Background Art

[0002] During the use of diesel engines, due to the low-temperature crystallization characteristics of diesel, especially in low-temperature environments in winter, diesel is prone to waxing, which makes it difficult to start the engine or even impossible to start. At present, there are some preheating systems applied to diesel engines on vehicles. When the vehicle stops, the controller will start the heating element in the preheating tank to preheat the diesel. At the same time, the controller will monitor the temperature in the preheating tank in real time. When the temperature reaches the set value, the heating element will be automatically turned off to avoid energy waste and overheating risks. Before the vehicle starts, the diesel in the preheating tank is transported to the diesel filter and oil pump through an electronic pump. Since the diesel has been preheated, its fluidity is greatly improved, which can effectively eliminate the waxing phenomenon and enable the engine to start smoothly.

[0003] Although the above-mentioned preheating system can preheat the diesel in the fuel tank, there is still a small amount of diesel in the filter element after the vehicle is shut down. In cold weather, the diesel in the filter element will still wax. Therefore, in order to prevent the diesel from waxing in the filter element, this device proposes an intelligent diesel management system that prevents the diesel from waxing. Utility Model Content
