TWO-CHAMBER FUEL VEHICLE TANK

摘要

The utility model relates to the fuel systems of internal combustion engines, and in particular to the fuel tanks of vehicles. The two-chamber fuel tank contains a main chamber 1 and an additional chamber 2, separated by a saddle 3. In the main chamber 1 there is a cup 4, in which the first fuel pump 5, the second fuel pump 6 and the intake jet pump 7. In the additional chamber 2 there is an overflow jet pump 8. The output of the first pump 5 is connected to the pressure line 9, connected to the fuel supply line 11 and to the input ohm bypass valve 12. The output of the bypass valve 12 is connected to the inputs of the intake and overflow jet pumps 7 and 8. The output of the second fuel pump 6 is connected to the inputs of the intake and overflow jet pumps 7 and 8 and is connected to the pressure line 9 through a spring-loaded check valve 13. B The fuel tank 14 is located in the main chamber 1 of the tank, and the fuel level sensor 15 is located in the additional chamber 2. At the outlet of the fuel supply line 11 and at the outlet of the second fuel pump 6, pressure sensors 16 and 17 are installed. The fuel level sensors 14 and 15 and the pressure sensors 16 and 17 are connected to the input of the electronic unit 18, the outputs of which are electrically connected to the fuel pumps 5 and 6. Improved reliability and efficiency of fuel supply to the engine from the two-chamber fuel tank. 1 ill.
