Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0030] figure 1 It is a schematic diagram of the usage status of the engine fuel consumption metering device according to an embodiment of the present invention; figure 2 for figure 1 The schematic diagram of the cooperation of the piston valve and the float in the figure. It should be pointed out that, figure 1 The middle piston valve part is shown simplified. Such as figure 1 and figure 2 As shown, the engine fuel consumption metering device of an embodiment of the present invention includes a flow meter 2 and a check valve 5 arranged on the fuel supply pipe 61 of the engine, and the fuel pumped from the fuel tank 1 passes through the flow meter 2 and the check valve in sequence. Enter the engine 6 to the valve 5, and burn to do work. When the fuel passes through the flowmet...

Abstract

The invention discloses an engine oil consumption measuring device and an automobile oil consumption management system using the engine oil consumption measuring device. The engine oil consumption measuring device comprises a flow meter, a one-way valve and an oil storage box, wherein the flow meter and the one-way valve are arranged on an oil supply pipe of an engine, the oil storage box is used for collecting fuel returning from an oil return pipe of the engine and conveying the fuel to the oil supply pipe of the engine, the upper portion of the oil storage box is provided with an oil inlet connected with the oil return pipe, the bottom of the oil storage box is provided with an oil outlet connected with the oil supply pipe, the connecting portion of the oil outlet and the oil supply pipe is located on the downstream of the one-way valve, and a control part used for controlling the opening and closing state of the oil outlet according to the height of the fuel in the oil storage box is arranged in the oil storage box. Due to the fact that the oil storage box is additionally arranged, the problem that measurement precision is influenced due to that the engine return oil is high in temperature and contains bubbles is effectively solved, real-time fuel consumption amount of the engine is precisely measured, and accurate oil consumption measurement is provided for engines of different types.

Description

technical field [0001] The invention relates to an engine oil consumption metering device and an automobile oil consumption management system, which can accurately measure the oil consumption of an engine with two oil inlet and oil return circuits. Background technique [0002] There are currently two types of fuel consumption metering devices known in the market. One is a liquid level sensor meter, which uses a fuel consumption sensor (the original car oil float and an additional liquid level sensor) to rise and fall inside the fuel tank with the increase or decrease of the oil volume. The principle is to obtain the detection signals of different liquid levels, calculate the oil volume in the fuel tank according to the liquid level, and analyze the fuel consumption data according to the change of oil volume; this method is greatly affected by the accuracy of the original car oil float and liquid level sensor, and the measurement can be obtained The data fluctuates greatly, ...
