The ultrasonic fuel excitation device can be widely applied to equipment for acquiring energy through various fuels, and has strong adaptability.

Description

technical field [0001] The invention relates to an ultrasonic excitation device, in particular to an ultrasonic fuel excitation device. Background technique [0002] An engine is a mechanical device that uses some kind of fuel to generate power, that is, a machine that converts fuel into heat energy through chemical energy, and finally into mechanical energy. Engine efficiency has two indicators: mechanical efficiency and thermal efficiency. Among them, the thermal efficiency is the ratio of the heat used to do work after the fuel is burned to the total heat that can be generated. Part of the heat generated by the complete combustion of fuel is taken away by the engine cooling system, part of it is discharged with the exhaust gas, and only a small part of the heat is used to do work. The thermal efficiency of existing internal combustion engines is very low, generally 20% to 25% for four-stroke gasoline engines, and even for high-performance engines, its thermal efficiency...
