The invention provides a high-precision fuel consumption meter and relates to the technical field of fuel consumption meters. The present invention includes a first fuel consumption meter housing and a second fuel consumption meter housing. A three-way valve is provided inside the first fuel consumption meter housing. The three openings of the three-way valve are respectively provided with a main oil supply pipe, an oil outlet pipe, and an oil return pipe. The ends of the main oil supply pipe and the oil outlet pipe far away from the three-way valve pass through the shell of the first fuel consumption meter, and a buffer oil tank is arranged inside the casing of the second fuel consumption meter. The housing of the meter and the second fuel consumption meter are in communication with the inner cavity of the buffer oil tank. The housing of the second fuel consumption meter is provided with multiple oil return tanks. The plurality of oil return tanks are connected with the inner cavity of the buffer oil tank. The lower side of the tank is provided with a force sensor for weighing. The invention solves the problem that the detection accuracy of the existing gravimetric fuel consumption meter is not high.
Description
technical field [0001] The invention relates to the technical field of fuel consumption meters, in particular to a high-precision fuel consumption meter. Background technique [0002] In the prior art, automobile testing stations mainly use fuel consumption meters to detect changes in vehicle fuel consumption during use. Fuel consumption meters can detect not only the technical status of fuel, but also the technical status of the engine and the entire vehicle. [0003] Although there are various fuel consumption meters at home and abroad at present, they all have their own deficiencies. Fuel consumption meters produced abroad have good performance and high reliability, but are expensive. Domestically produced fuel consumption meters have poor reliability and low measurement accuracy. Accurately detecting the fuel economy of a car can reduce the cost of using the car, save oil resources, and achieve the purpose of saving energy. [0004] There are many types of fuel consum...
