Ultrasonic atomization fuel auxiliary supply system

Abstract

The invention discloses an ultrasonic atomization fuel auxiliary supply system. The system is characterized in that an ultrasonic atomization generator is matched with a Venturi mixer for use, so thatpremixed fuel gas with a certain proportion of fresh charge entering an engine is realized, the combustion heat efficiency of the engine is effectively improved, the emission of harmful gas of the engine is reduced. The system mainly aims at a fuel supply system of methanol which is a clean fuel, utilizes the ultrasonic atomization unit to atomize methanol into methanol mist, is matched with thenegative pressure adsorption principle of the Venturi tube, and realizes premixing of air and methanol mist through the adjusting function of an electronic throttle valve on the air inlet flow; and the heat efficiency of the engine is improved in an auxiliary fuel gas supply mode of the premixing part, and emission of the engine is improved.

Description

technical field [0001] The invention mainly relates to the field of engine fuel supply systems, in particular to an ultrasonic atomized fuel auxiliary supply system for methanol vehicles. Background technique [0002] With the increasingly stringent requirements for energy saving and emission reduction, the technological progress of internal combustion engines is an inevitable requirement of the development of the times. In order to adapt to increasingly stringent emission regulations, engines generally follow two technical routes for technological transformation. The first technical route is to carry out technical transformation of traditional engines to improve the thermal efficiency of transmission engines and reduce emissions; the second technical route It is to use cleaner fuels to improve engine emissions and improve fuel thermal efficiency. [0003] In recent years, a variety of clean fuels have been used in automobiles, such as reformulated gasoline, ethanol, biodie...

AI Technical Summary

Problems solved by technology

[0003] In recent years, a variety of clean fuels have been used in automobiles, such as reformulated gasoline, ethanol, biodiesel, natural gas methanol, hydrogen, etc. Among them, methanol is a recognized clean energy with fast combustion rate, good antiknock performance, low Pollution and no smoke are the preferred alternative fuels for vehicles. Many countries in the world are applying methanol to vehicles, and research in this field has also made great progress. Methanol vehicles have also achieved road running. , but there are still many problems, such as the mechanism of methanol combustion and low emissions, the life and reliability of alcohol-resistant key components, etc.
