自加热柴油机燃油供油系统及供油方法
摘要：
本发明涉及柴油发动机供油系统，为解决现有柴油机在低温环境下不能使用高牌号的柴油问题；提供一种自加热柴油机燃油供油系统，包括柴油发动机、储装高牌号柴油的主油箱；其特征在于还包括储装低牌号柴油的副油箱，所述柴油发动机的燃油受油端经输油管路与所述主油箱和副油箱连接，所述输油管路上设置有开关阀；所述主油箱内设置有流体供热的热交换器，所述热交换器的出入口连接在所述发动机的冷却液循环通道上。本发明具有柴油加热功能，可以保证在超低温环境中持续使用高牌号的燃油，获得燃油使用经济性。
摘要（英）：

The invention relates to a diesel engine fuel oil supply system, which aims to solve the problem that an existing diesel engine cannot use high-grade diesel oil under a low-temperature environment. The invention provides a self-heating diesel engine fuel oil supply system, which comprises a diesel engine, and a main oil tank for storing and filling the high-grade diesel oil, and is characterized by further comprising an auxiliary oil tank for storing and filling low-grade diesel oil. A fuel oil receiving end of the diesel engine is connected with the main oil tank and the auxiliary oil tank through an oil conveying pipeline; a switch valve is arranged on the oil conveying pipeline; a heat exchanger with a fluid for supplying heat is arranged in the main oil tank; and an inlet and an outlet of the heat exchanger are connected onto a cooling liquid circulation channel of the engine. The self-heating diesel engine fuel oil supply system provided by the invention has a diesel oil heating function, and the high-grade diesel oil can be continuously used under the ultralow-temperature environment, and the using economic effectiveness of fuel oil is achieved.
