Problems solved by technology

[0004] 1. Since the volume of fuel oil changes with temperature, the measurement accuracy is greatly affected by the change of working temperature
[0005] 2. The flow detection head is connected in series in the fuel pipeline to affect the fuel supply pressure of the engine, so it also affects the fuel consumption rate of the engine
[0006] 3. The current volume flow detection heads are all driven by oil pressure, and there is a fuel pressure difference between the inlet and outlet, which will inevitably cause internal leakage of fuel between the inlet and outlet, which will affect the measurement accuracy

Embodiment 1

[0016] Embodiment 1: as figure 1 As shown, the fuel consumption tester is mainly composed of a computer (1) and a flow detection head (16). Such as figure 2 and image 3 As shown, there are two DC motors in the flow detection head, two flow sensors of the same size, two pressure difference and temperature sensors and a difference counter. The oil inlet motor 9 drives the oil inlet flow sensor 9 and the oil inlet gear 25, the oil return motor 3 drives the oil return flow sensor 4 and the oil return gear 19, and there are two pipes connected to the inlet of the flow sensor respectively on the pressure difference and temperature sensor 10. On the oil port 28 and the oil outlet 35, the DC motor, the difference counter, the differential pressure and the temperature sensor all have wires to be connected with the computer 1 . Difference counter 6 is composed of oil return motor shaft 18, oil return gear 19, difference counter housing 20, planetary gear 21, planetary gear shaft 22...

Embodiment 2

[0017] Embodiment 2: as Figure 5 As shown, there are two DC motors inside the flow detection head, two flow sensors of the same size, two differential pressure and temperature sensors and two electronic counters 11, the oil inlet motor drives the oil inlet flow sensor and the electronic counter, and the oil return motor Drive the oil return flow sensor and the electronic counter. There are two tubes on the pressure difference and temperature sensors respectively connected to the oil inlet 28 and the oil outlet 35 of the flow sensor. The DC motor, the electronic counter, the pressure difference and the temperature sensor all have wires Connect to computer 1. The working principle is basically the same as that of Embodiment 1, except that there is no differential timer in the sensor, but electronic counters 11 are respectively installed on the two flow sensors. The electronic counter records the rotational speeds of the two flow sensors respectively, and then transmits the two...

Abstract

The invention discloses an oil consumption tester for testing the oil consumption of an engine, belonging to the field of mechanical and electrical technologies. The oil consumption tester mainly comprises a flow measuring head and a computer, wherein the flow measuring head comprises two motors, two flow sensors, an oil pressure and temperature sensor and the like. Firstly, the computer receives an oil pressure signal sent by the oil pressure and temperature sensor and then gives a command to control the corresponding motor to drive the corresponding flow sensor to rotate. Because oil consumptions of two oil tubes are different, the numbers of turns for the rotation of the two flow sensors are different, and the oil consumption of the engine can be obtained by measuring the difference between the numbers of turns. Because oil pressure drive is replaced with motor drive, the oil supply pressure of the engine can not be influenced, oil leakage can also not be caused, and the measuring precision is improved. Errors caused by temperature change can be eliminated due to the existence of the temperature sensor.

Description

[0001] Field [0002] The invention relates to a device for measuring the fuel consumption of an engine, which belongs to the field of electromechanical technology. technical background [0003] Currently used fuel consumption detection devices are divided into weighing method and volume method according to the principle. The volumetric method is now widely used. The advantages of the volume method are: convenient application, not limited by factors such as occasions and models; the disadvantages are: [0004] 1. Since the volume of fuel oil changes with temperature, the measurement accuracy is greatly affected by the change of working temperature. [0005] 2. The flow detection head is connected in series in the fuel pipeline to affect the fuel supply pressure of the engine, so it also affects the fuel consumption rate of the engine. [0006] 3. The current volumetric flow detection heads are all driven by oil pressure, and there is a fuel pressure difference between the i...
