Fuel reformer and fuel supply system using the same

Abstract

A fuel reformer for fully reforming (fine-graining) liquid fuel fed to an internal combustion engine including an internal combustion engine with large displacement and a fuel supply system using the same. A fuel reformer comprising an inflow port which is provided in a pipe connecting a fuel tank and an internal combustion engine and into which fuel flows, an outflow port out of which the fuel flows, a reforming space located between the inflow port and the outflow port, a vibrating portion provided on at least one side of the reforming space, and an ultrasonic vibrator for vibrating the vibrating portion, and generating nanobubbles by applying an ultrasonic wave to the fuel which is passing, comprises a fuel rotating mechanism for rotating the liquid fuel which flows in from the inflow port along the vibrating surface of the vibrating portion by the vibration of the vibrating portion and a perpendicular moving mechanism for spirally moving the liquid fuel perpendicularly to the vibrating surface toward the outflow port.

Description

technical field [0001] The present invention relates to a fuel reforming device and a fuel supply system using the fuel reforming device. To upgrade. Background technique [0002] Patent Document 1 provides a device for the purpose of pre-gasifying fuel supplied to an internal combustion engine for complete combustion. Ultrasonic vibrations are generated in a tank containing fuel for an internal combustion engine to decompose the fuel into ultrafine particles, and then the fuel is supplied to the internal combustion engine. Vaporize it before feeding it to the internal combustion engine. Specifically, the gasification generating device is composed of a gasification box, an output vibrating element built in the gasification box, and an empty burning prevention switch. [0003] Patent Document 2 provides a fuel improvement device in which an ultrasonic vibrator is installed on a fuel path to atomize fuel, and a magnet or electromagnet is installed downstream thereof to furth...

AI Technical Summary

Problems solved by technology

However, as disclosed in Patent Document 1 and Patent Document 4, when ultrasonic vibration is applied to the liquid fuel in the fuel tank to reform the liquid fuel, the reformed fuel undergoes a mixing process with air to reach Combustion stroke, but since there is a distance from the tank to the combustion stroke, there is a possibility of reforming and deteriorating, and it is impossible to reform the entire fuel contained in the tank equally, so the disadvantage of uneven combustion performance occurs

[0011] Moreover, in the fuel improvement device described in Patent Document 2, since the ultrasonic vibration device is arranged on a normal pipe, the efficiency of atomization of the passing liquid fuel is poor. In the fuel oil reforming device, the liquid fuel that is vibrated by the ultrasonic vibrator is only the fuel that passes through the fuel oil filter bracket before being sent to the fuel oil outflow pipe. Since the passing speed of the fuel is fast, there is a problem that it cannot be fully processed. Defects of modification (micronization)

[0012] In addition, since fuel is supplied at a large flow rate to a large-displacement internal combustion engine such as a ship or a diesel engine, there is a disadvantage that a sufficient effect cannot be obtained by the conventional method.

In addition, in the case of a fuel-injected internal combustion engine having a common rail, there is a problem of insufficient pressure when installed immediately after the fuel pump.
