The lower parts of the first fuel tank 6, the second fuel tank 7 and the third fuel tank 8 are connected in series through oil pipelines, and the upper parts are connected with the outside through ventilation pipelines; the reserve first fuel tank 6, the electric fuel delivery pump I9 and the daily first fuel tank 2 are sequentially connected through an oil pipeline; the third reserved fuel tank 8, the second electric fuel delivery pump 10 and the daily second fuel tank 3 are connected in sequence through a fuel delivery pipeline.
An oil mass sensor flange arranged on the first daily fuel tank 2 is connected with the first oil mass sensor 5, so that the oil mass of the daily fuel tank is monitored in real time, and signals are sent to an instrument desk of a cab. An air filter flange is arranged above the first daily fuel tank 2 and connected with an air filter; an air filter flange is arranged above the second fuel tank 3 and connected with an air filter.
The oil mass sensor flange that first fuel tank 6 of deposit set up be connected with oil mass sensor two 11, the oil mass of real time monitoring daily fuel tank is on sending the driver's cabin instrument desk with the signal.
After the vehicle is started, the fuel oil in the daily first fuel tank 2 flows into the fuel supply pipeline through the oil pipe of the daily first fuel tank 2, flows into the engine 1 after being filtered by the oil-water separator 4, and simultaneously the fuel oil in the daily second fuel tank 3 flows into the daily first fuel tank 2 through the oil pipe, and the liquid levels of the two fuel tanks are kept consistent. The redundant fuel oil flows into an oil return pipeline through an oil return opening of the engine 1 and flows back to the first daily fuel tank 2. When the oil quantity is insufficient, a first oil quantity sensor 5 on the first daily fuel tank 2 sends a signal to the instrument, when the instrument displays that the fuel oil is insufficient, switches of a first electric fuel oil delivery pump 9 and a second electric fuel oil delivery pump 10 are turned on, so that the fuel oil in the first reserved fuel tank 6, the second reserved fuel oil tank 7 and the third reserved fuel oil tank 8 flows into the first electric fuel oil delivery pump 9 and the second electric fuel oil delivery pump 10 through oil delivery pipelines and then flows into the first daily fuel oil tank 2 and the second daily fuel oil tank 3, when the first oil quantity sensor 5 on the first daily fuel oil tank 2 sends a signal to the instrument, and when the instrument displays FULL, the first electric fuel oil delivery pump 9 and the second electric fuel oil delivery pump 10 are turned off.
