Gasohol pump

Abstract

The invention discloses a gasohol pump, and belongs to the technical field of fuel additive adding devices. The gasohol pump mainly comprises a shell sleeve, a rotary cover, a gas return base, a control sleeve and a ferrule, wherein a gas return pipe is inserted into the gas return base; a gas return channel is formed in the gas return base; a liquid flowing channel is formed between the gas return base and the ferrule; a first protrusion and a second protrusion are arranged in the control sleeve; the first protrusion is used for blocking the gas return channel; the second protrusion is used for blocking the liquid flowing channel; a gas return port and a liquid outlet are formed in the end part of the control sleeve. According to the gasohol pump, the adding quantity of gasohol can be accurately controlled, and waste of the gasohol can be avoided. The gasohol pump is widely applied to use and maintenance of automobiles.

Description

technical field [0001] The invention relates to a fuel additive adding device, in particular to a gasoline fine pump, which belongs to the field of fuel adding devices for mechanical power devices. Background technique [0002] The popularity of automobiles as a means of transportation has entered the daily lives of more and more ordinary people. However, most people just use cars and hope that car maintenance can be foolish, which puts forward higher requirements on the economical fuel economy, emission standards and maintenance-free properties of cars. Studies have shown that adding appropriate additives to automobile fuel (domestic cars are mainly gasoline) can effectively improve the performance of the fuel and increase the combustion speed of the fuel to an appropriate range. Because after the fuel additive is added to the gasoline, it can form a protective layer on the surface of the intake system of the intake valve to prevent a large amount of deposits inside the en...

AI Technical Summary

Problems solved by technology

But there are also certain defects. For example, when part of the fuel additive needs to be added, it is necessary to close the liquid outlet channel of the inner hole through the first partition in time, and because the first partition is far away from the liquid outlet, the gasoline essence When the pump is removed, the fuel additive will remain in the inner hole between the liquid outlet and the first spacer

These disadvantages not only lead to inaccurate dosing of fuel additives, but also lead to waste of fuel additives

Especially when used on a large scale, it can seriously increase the overall consumption of fuel additives and increase the cost of daily use
