AI Technical Summary
Technical Problem
In existing diesel dual-tank systems, the vehicle cannot move and there is insufficient fuel supply pressure when the main tank fails.
Method used
Design a fuel system that allows the first and second fuel tanks to supply fuel to the engine independently, and prevents fuel from entering each other through a one-way valve. Set up a level sensor and fuel pump control method to ensure independent fuel supply and stable fuel supply pressure.
Benefits of technology
It reduced the failure rate, increased the vehicle's driving range, and ensured that the other fuel tank could still supply fuel normally if one fuel tank failed, thus avoiding insufficient fuel supply pressure.

Abstract
本发明公开了一种燃油系统及燃油系统的控制方法、车辆。该燃油系统包括：发动机、第一和第二油箱、回油管、第一和第二油泵、第一和第二单向阀，第一油箱和第二油箱的出油口均与发动机的进油口相连；回油管连接发动机与第一油箱的回油口；第一油泵驱动第一油箱油液流向发动机；第二油泵驱动第二油箱油液流向发动机；第一单向阀设在第一油箱与发动机之间且允许第一油箱的油液向发动机流动；第二单向阀设在第二油箱与发动机之间且允许第二油箱的油液向发动机流动。根据本发明的燃油系统，第一油箱和第二油箱可以独立向发动机供油，保证了某一个油箱失效时，另外一个油箱依然可以工作保证汽车行驶，降低了故障率，单向阀可以改善供油压力不足。
