Abstract

The invention discloses an engine fuel cooling device, a cooling method and engineering machinery. The engine fuel cooling device comprises a water pump, a water tank and a water cooling cavity, wherein the water tank is connected with the water pump, and the water cooling cavity is arranged in an engine fuel filter and formed by a water cooling pipeline. Moreover, a water inlet pipe and a water return pipe of the water cooling pipeline are respectively communicated with the water tank. The engine fuel cooling device and the engine fuel filter are integrated, so that arrangement space can be effectively decreased. Moreover, as engine fuel is cooled by means of water cooling, compared with an active method for cooling the fuel by the aid of a fan and the like, cooling energy consumption can be reduced, and cooling effects are further improved.

Description

technical field [0001] The invention relates to the technical field of motor vehicle fuel cooling, in particular to an engine fuel cooling device, a cooling method and engineering machinery. Background technique [0002] The fuel system of the engine directly affects the power, economy and safety of the vehicle. With the development of engine technology, the temperature requirements of fuel are also raised. The temperature of the engine fuel must not be too high. The fuel is delivered to the engine, part of it is burned, and the remaining heated fuel returns to the fuel tank, increasing the temperature inside the fuel tank. Due to the frequent operation of the engine, the fuel is not cooled and enters the engine, which will affect the operation of the engine. [0003] At present, fuel cooling is mainly achieved through cooling fins to reduce the temperature. For example, Chinese patent CN201620978U discloses a fuel cooling structure for vehicles, which includes a first o...
