Abstract

The invention discloses an engine hybrid power system based on alternative fuel. The engine hybrid power system is composed of a traditional internal combustion engine, a three-stage energy utilization device composed of a waste gas turbocharger, a high-temperature cracker and a fuel pre-heater, a proton exchange membrane fuel cell, a hydrogen palladium membrane purifier for improving the purity of high hydrogen on site, a fuel high-pressure common rail jetting device used for meeting the alternative fuel supply and a system electronic control unit. According to the novel hybrid power system disclosed by the invention, the energy multi-level utilization management is comprehensively applied, so that the hundred percent of the fuel can be fully utilized, aims at overcoming the technical problems that the alternative fuel is difficult to burn in a direct engine and the power generation efficiency of a direct fuel cell is low, meanwhile, the technical short plates that the hydrogen fuel cell is difficult to store hydrogen, the power consumption of the waste gas turbocharger is large are made up; an internal combustion type and electrochemical hybrid power generation mode is adopted, and provides a novel method for efficiently utilizing biological oil to replace fuel.

Description

technical field [0001] The invention relates to an engine, in particular to a combustion-type and electrochemical-type engine hybrid power system based on alternative fuels, which is suitable for the fields of transportation tools, emergency backup power supplies, and the like. Background technique [0002] With the rapid development of social science and technology and the substantial improvement of living standards, human beings' demand for energy and power is becoming more and more urgent, especially in industries such as electricity and transportation, which consume a large amount of oil resources every day, causing deterioration of the atmospheric environment. In addition, oil is a non-renewable resource. At present, oil supply is in short supply and international oil prices continue to rise. It is increasingly urgent to find suitable alternative fuels and new power devices. [0003] Alternative fuels such as general alcohols and bio-oils have superior characteristics s...
