All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1 to 2, an embodiment of the present application discloses a fuel consumption measuring system, including: the device comprises a fuel tank 1, a constant flow fuel pump 2, a testing mechanism 3 and an engine 4; the fuel tank 1 is respectively connected with the engine 4 and the testing mechanism 3; one end of a constant flow fuel pump 2 is connected with the fuel tank 1, and the other end is connected with a testing mechanism 3; the fuel tank 1 is used for containing fuel, the testing mechanism 3 is used for measuring the fuel consumption of the fuel, and the constant flow fuel pump 2 is used for controlling the opening or closing state of a fuel transmission channel from the fuel tank 1 to the testing mechanism 3.
In the embodiment of the application, a fuel consumption measuring system is provided, and a testing mechanism 3 on the system can measure the fuel consumption of an engine 4 in real time in the process that the engine 4 runs through fuel, so that the fuel economy of a whole vehicle can be analyzed according to measured data while the manual measuring cost is reduced.
Alternatively, before the fuel consumption of the engine 4 is measured, a sample of the fuel to be drawn is sent to the testing entity 3, the testing mechanism 3 therefore comprises a testing tank 21 for containing the fuel to be measured delivered by the fuel tank 1, and a first fuel level sensor 22 for sensing the level of the fuel in the testing tank 21, wherein the first fuel level sensor 22 is provided with a sensing height as a condition for triggering the turning on of the constant flow fuel pump 2, for example, when the constant flow fuel pump 2 has been switched on, during the process of filling the fuel tank 1 into the test fuel tank 21, the fuel level in the test fuel tank 21 reaches the sensing height of the first fuel level sensor 22, the constant flow fuel pump 2 is triggered to shut down and the fuel tank 1 stops filling the test tank 21.
In practical application, in a common process of an oil supply and return loop of an oil tank, fuel oil flows out of the fuel tank 1 and supplies oil to the engine 4 through a pipeline, then the fuel oil is mixed with air in a cylinder of the engine 4 for combustion, gas generated during combustion expands to push a piston to make linear motion, a crankshaft rotates through a crank-link mechanism, then combustion heat energy is converted into mechanical energy, and finally the residual fuel oil after combustion work is returned to the fuel tank 1 from the engine 4 through an oil return pipeline. In order to measure the economy of the whole vehicle, a measuring system for measuring the fuel consumption condition needs to be arranged. In order to ensure the continuity of the measuring process, the measuring system can comprise a first three-way electromagnetic valve 5 and a second three-way electromagnetic valve 6, wherein the first three-way electromagnetic valve 5 and the second three-way electromagnetic valve 6 are used for controlling the transmission direction of fuel oil, the two electromagnetic valves are arranged on a loop pipeline for supplying and returning fuel oil to the fuel tank 1, and specifically, a port of the fuel tank 1 is respectively connected with one end of an engine 4 and a port of a test fuel tank 21 through the first three-way electromagnetic valve 5; the other end of the engine 4 is respectively connected with the interface of the fuel tank 1 and the interface of the test fuel tank 21 through a second three-way electromagnetic valve 6. The two three-way electromagnetic valves are two-position three-way electromagnetic valves, the opening and closing states of the three-way electromagnetic valves are controlled by electromagnetic valve coils, when the electromagnetic valve coils are electrified, the second three-way electromagnetic valve 6 is used for transmitting fuel oil from the fuel tank 1 to the engine 4, and the first three-way electromagnetic valve 5 is used for returning the fuel oil from the engine 4 to the fuel tank 1; when the solenoid valve coil is powered off, the second three-way solenoid valve 6 is used for transferring fuel from the test fuel tank 21 to the engine 4, and the first three-way solenoid valve 5 is used for returning fuel from the engine 4 to the test fuel tank 21.

In the process of testing oil supply and oil return of the oil tank 21 and the engine 4, if the liquid level height of the fuel in the test oil tank 21 reaches the sensing height of the second fuel level sensor 23 within the preset time, the first three-way electromagnetic valve 5 and the second three-way electromagnetic valve 6 are switched to a pipeline of the fuel tank 1 to form a loop for oil supply and oil return between the fuel tank 1 and the engine 4, meanwhile, the second fuel level sensor 23 triggers the constant flow fuel pump 2 to be started, the fuel tank 1 transmits the fuel to the test oil tank 21 again until the liquid level height of the fuel added into the test oil tank 21 reaches the sensing height of the first fuel level sensor 22, and the fuel tank 1 stops supplying the fuel to the test oil tank 21 again.
Alternatively, after the fuel tank 1 transfers fuel to the test fuel tank 21 again until the fuel level in the test fuel tank 21 reaches the sensing height of the first fuel level sensor 22, the consumption of fuel in the measurement process can be obtained only by calculation and analysis.
