Supply control system and method for engine oxygen-enriched micro-nano bubble fuel

Abstract

The invention relates to the technical field of vehicle engine fuel pretreatment. The invention provides a supply control system for engine oxygen-enriched micro-nano bubble fuel, which comprises a fuel tank, an air filter, a fuel tank valve, a fuel filter, a controllable four-way valve, a transmission mechanism, an oxygen-enriched micro-nano fuel generation system, an oxygen-enriched micro-nano bubble fuel storage device, a pressure limiting valve, a fuel-gas separation device, a fuel flow sensor, a high-pressure fuel pump, a high-pressure fuel rail, a fuel sprayer, a fuel pressure regulating valve, an ECU, a fuel tank pressure sensor, a fuel tank position sensor and a first bubble concentration sensor. The invention further provides a supply control method of engine oxygen-enriched micro-nano bubble fuel. The fuel preparation quality of an engine under different rotating speeds and working conditions can be effectively improved, the oxygen content in the engine is improved, the atomization characteristic of the fuel is improved, and therefore the combustion process of the engine is optimized.

Description

technical field [0001] The invention is applied in the technical field of vehicle engine fuel pretreatment, and specifically relates to a supply control system and method for engine oxygen-enriched micronano-bubble fuel. Background technique [0002] At present, the technologies for improving the atomization quality of fuel and the oxygen content in the cylinder mainly include variable supercharging, variable valve, blended fuel, high-pressure injection, cavitation injection, dual-fuel injection, etc. Although the above-mentioned technologies can improve engine fuel The effect of atomization quality and oxygen content in the cylinder, but these technologies have fallen into a bottleneck at present, further improving the atomization quality of fuel and the oxygen content in the cylinder through these technologies will lead to a more complex engine structure and an increase in the pressure and temperature in the engine cylinder. High, the load of each load part increases, the ...
