Description

Technical Field

[0001] The utility model relates to the technical field of vehicle water circuits, in particular to a vehicle integrated water circuit assembly system. Background Art

[0002] In northern China and the Qinghai-Tibet Plateau region, winter is long and the lowest temperature can reach below -30°C. Using high-grade diesel in such cold conditions can cause fuel waxing. At the same time, the viscosity of commercial vehicle fuel diesel is greatly affected by the ambient temperature. The lower the temperature, the greater the viscosity, and it is easy to form a milky viscous mixture, resulting in a decrease in fluidity and causing the phenomenon of oil circuit blockage (waxing). In serious cases, it will block the entire supply system and prevent the vehicle from starting normally.

[0003] To solve the above problems, many fuel system heating devices have emerged on the market. There are mainly two fuel system heating schemes, namely electric heating and water heating. Electric heating is the electric heating type oil level sensor scheme, and its power source is the on-vehicle battery of the commercial vehicle. The electricity of the battery is led to the oil level sensor of the fuel supply system. The fuel oil level sensor integrates a heater and a control circuit to heat the fuel near the oil suction port of the fuel tank. After the fuel is heated, it can be used as the fuel supply system for normal driving. The water heating scheme is the engine coolant heating scheme. Generally, a main and auxiliary fuel tank design is adopted to heat the fuel in the main fuel tank of the fuel supply system. Because the coolant needs to have a high temperature after the engine starts and the fuel burns, low-grade fuel is needed to start the engine first, and then the coolant is used to heat the high-grade fuel. After the fuel is heated, it can be used as the fuel supply system for normal driving.

[0004] For the water heating system, the existing commercial vehicle water heating systems generally adopt a non-integrated water circuit, that is, the urea nozzle cooling pipeline, the urea tank heating pipeline, and the fuel tank heating pipeline all take and return water from the engine. This design not only has high costs, but also has low space utilization, difficult installation and maintenance, resulting in waste of space and labor. Content of the Utility Model
