Problems solved by technology
The structure of the automobile air flowmeter mainly includes a tubular shell and a flowmeter body. The air flowing through the surface of the flowmeter is detected through the flowmeter body. In order to test more data to achieve the detection of the air flowing through it, it will be used in the automobile engine. Add relevant detection sensors on the engine to make the engine fuel burn more fully and reduce exhaust emissions, but it is cumbersome to set them up separately
However, many car manufacturers are still using old design schemes, which do not meet the national call for energy conservation and emission reduction

Embodiment Construction
[0018] The present invention will be further described below in conjunction with the drawings and preferred embodiments.
[0019] Such as Figure 1 to Figure 4 As shown, the four-in-one high-precision automobile air flow meter involved in this embodiment includes a wiring harness socket 1, a connecting end 2, and a detection column 3 in sequence. The detection column 3 is provided with a control circuit board (not shown in the figure), A hot wire flow sensor 4 is electrically connected to the control circuit board, and the control circuit board is also electrically connected to a pressure sensor 5, a temperature and humidity sensor 6 and a thermistor 7, and the thermistor 7 is a negative temperature coefficient thermistor. When the temperature is higher, the resistance value is lower. Through the integrated setting of each sensor, the overall mass of the flow meter is reduced and the detection function is diversified. The detection column 3 includes a detection front end 31 and a...

The invention discloses a four-in-one high-precision vehicle air flow meter which sequentially comprises a wire harness socket, a connecting end and a detecting column. A control circuit board is arranged in the detecting column, electrically connected with a hot wire type flow sensor and further electrically connected with a pressure sensor, a temperature and humidity sensor and a thermistor. Through the four-in-one integrated arrangement, the whole flow meter is lower in weight, oil consumption is reduced, and the manufacturing cost is reduced; due to the chamfering design of an air duct opening, fluid design is optimized, air flow resistance is reduced, engine fuel is more sufficient in combustion, emission is reduced, and the flow meter is more environmentally friendly; due to the integrated design, measuring points are integrated on one basis, efficiency and performance are further improved, overall functions are complete, and practicability is strong.
Description
Technical field [0001] The invention relates to an automobile air flow meter, in particular to a four-in-one high-precision automobile air flow meter. Background technique [0002] Air flow meter, also known as air flow sensor, is one of the important sensors of EFI engine. It converts the inhaled air flow into an electrical signal and sends it to the electronic control unit (ECU). As one of the basic signals for determining fuel injection, it is a sensor that measures the air flow into the engine. [0003] At present, an air flow meter is usually installed on the intake system of an automobile engine to accurately detect the air flow rate, so that the engine electronic injection system can work with high quality and high efficiency, thereby reducing engine fuel consumption. The structure of an automobile air flow meter mainly includes a tubular casing and a flow meter body. The air flow through the surface of the air flow through the flow meter body is tested. In order to test mo...
