Engine carburetor liquid level control device

Abstract

The invention discloses an engine carburetor liquid level height regulating device. The engine carburetor liquid level height regulating device comprises an oil storage cup, a lifting mechanism, a displacement sensor, a liquid level sensor, a control device and an oil storage cup support, wherein one side of the lifting mechanism is movably connected with the oil storage cup support, the other side of the lifting mechanism is fixedly connected with a gasoline octane value measuring machine body, the displacement sensor and the liquid level sensor are connected to the oil storage cup support and the oil storage cup, and the control device controls the movement of the lifting mechanism relative to a carburetor and measures the liquid level height of the oil surface of the oil storage cup in real time according to signals input by the displacement sensor and the liquid level sensor. Compared with the prior art, the device has the advantages that the liquid level height of the carburetor is regulated through the displacement sensor and the liquid level sensor, so that the problem of testing lag is effectively controlled, and reliability and sensitivity of a system are improved. In addition, the device is suitable for the technical field of gasoline octane value measurement.

Description

technical field [0001] The invention relates to an engine oil supply control device, in particular to an engine carburetor control device, which is applied in the technical fields of automobile gasoline octane number measurement and engine fuel supply devices. Background technique [0002] The octane number is the most important anti-knock index of motor gasoline, which is determined by the knock index when it is burned in a special gasoline engine. When the gasoline octane number tester measures the gasoline octane number, the knock index of the oil product is related to the oil-gas mixing ratio. The air intake of a fixed-displacement engine is fixed, and the supply of oil is determined by the liquid level of the carburetor. Therefore, the correct adjustment of the liquid level of the carburetor is the key to accurately measuring the octane number. . [0003] The existing technology generally realizes the regulation of the liquid level of the carburetor through the struct...

AI Technical Summary

Problems solved by technology

[0004] 1. Affected by the cleanliness of the oil, the needle valve in the float chamber is easily blocked or closed tightly, causing the liquid level to be out of control;

[0005] 2. This liquid level automatic control system has significant hysteresis characteristics, and then affected by external vibrations, the float repeatedly shifts to control the liquid level, causing liquid level fluctuations in the float chamber, resulting in inaccurate octane number measurement results
