Description

technical field [0001] The invention relates to the technical field of engine fuel pretreatment, in particular to a bubble flow premixed hydrocarbon fuel preparation and supply system and a control method thereof. Background technique [0002] At present, the mixing uniformity of fuel and air is mainly improved through the use of high-pressure injection technology, variable valve technology and intake coordination control. Although the application of the above technology can improve the atomization degree of fuel and improve the mixing uniformity, if the current technical route is adopted to further improve the mixing uniformity, the complexity of the engine system and control will be greatly increased, and the actuator’s influence on the material strength will be increased. requirements, greatly increasing the manufacturing cost of the vehicle. [0003] By premixing fuel and air at the nanometer scale, the properties of the fuel can be improved, the mixing uniformity of th...
