Description
Technical field
The present invention relates to a kind of fuel reproduction system of internal-combustion engine, particularly a kind of fuel reproduction system that is applied to the internal-combustion engine of landway traffic tool.
Background technique
From excavating oil in 1859 and from German's Otto in 1876 after (Nikolaus Otto) improve internal-combustion engine, the standard that oil and internal-combustion engine become rapidly human traffic and generating is equipped with, and because oil energy density height and convenient transportation, become the main energy sources of traffic, industrial chemistry raw material and generating, and then drive the Fast Growth of global economy.
Since the industrial revolution, owing to human a large amount of fossil fuels that use cause the discharge amount of carbon dioxide sharply to increase, cause global greenhouse gases effect, the global warming temperature is risen and climatic anomaly, threaten human health and existence.Particularly internal-combustion engine is when using fossil fuel burning switching energy, can cause the discharging of waste gas used heat, and contain the hydrocarbon (HC) of carbon monoxide (CO), incomplete combustion, nitrogen oxide (NOx) and oxysulfide (SOx) that can be carcinogenic in the waste gas, and the harmful gas such as soot particle (PM).And enter in the atmosphere because harmful gas is mode with hot gas, can produce serious heat island effect, and then the high temperature in aggravation city.
According to (the Environmental Protection Agency of U.S. environment protection mechanism; EPA) analyze; in fossil fuel and the CO2 emission; the discharging of petrochemical industry generating accounts for 35%; account for 27% with fossil fuel as the discharging of traffic; industrial discharge accounts for 20%, and the people's livelihood and family's discharging account for 11%, and the agricultural pollution discharging accounts for 7%.Wherein generating, traffic and industrial discharge account for the discharge amount more than 80% altogether, and are used for the fossil fuel discharging of traffic, and the small size gasoline locomotive accounts for 58%, bus and lorry account for 17%, railway traffic accounts for 2%, and boats and ships account for 5%, and air traffic accounts for 10% etc.Wherein, land communications have accounted for the discharging more than 80% altogether.Therefore, the pollution utmost point that causes of fossil fuel and internal-combustion engine need solve.
And with the internal-combustion engine technology of fossil fuel as the energy, serious efficient blind spot is arranged.Take gasoline as example, after the stroke operation of gasoline via air inlet, compression, power and the exhaust of internal-combustion engine, chemical energy can be transformed into mechanical energy comes for load and traffic circulation, wherein the running during auto idle speed consumes 17.2% chemical energy approximately, consume approximately and reach 62.4% chemical energy and convert the waste gas such as CO, CO2, NOx, SOx and PM and used heat to, and the chemical energy of internal-combustion engine consumption 18.2% is converted to mechanical energy, to supply periphery, rain brush, sound equipment, air-conditioning and generator, internal-combustion engine to the transmission of gearbox consumes about 5.6% chemical energy.Yet, the chemical energy that applies to the traffic transmission only is 12.6%, and 12.6% chemical energy more consumes in windage, brake and rolling resistance etc., therefore can learn in 100% the fossil fuel, only change about 12.6% chemical energy in transmission, and convert waste gas and waste heat discharge to up to 62.4% chemical energy, cause fossil energy consumption and befouling environment.

When one, the gas source of internal-combustion engine is air, because the ratio about 78% of nitrogen in the air, the ratio of oxygen about 21%, therefore it is main that the high-temp waste gas that produces is mainly carbon dioxide, water vapor and nitrogen oxide, and also might produce CO (carbon monoxide converter) gas and hydrocarbon when incomplete combustion; In addition, utilizing molecular particle size screening unit mainly is that carbon dioxide is separated with water vapour, and then the cooled liquid water of brine electrolysis steam produces hydrogen and oxygen, the final reaction device can carry out carbon dioxide and hydrogen are carried out the synthetic reaction of generative fuel, and reacting required temperature then provides heat to reach by high-temp waste gas during through reaction device.
Two, because with air during as the gas source of internal-combustion engine, in the high-temp waste gas that internal-combustion engine produces, therefore nitrogen oxide and CO (carbon monoxide converter) gas are to the unfriendly gas of environment, screen at internal-combustion engine and molecular particle size between the unit converting unit to be set nitrogen oxide, CO (carbon monoxide converter) gas are become nitrogen, oxygen, carbon dioxide and water vapour with hydrocarbon conversion; Therefore, the content that converting unit not only can improve carbon dioxide and water vapour is synthetic in order to generative fuel, more can thereby reduce the pollution to environment.In addition, molecular particle size screening unit more can utilize the nitrogen molecule sieve to isolate nitrogen to synthesize generative fuel for reaction device.
Three, when the gas separation unit in order to separation of nitrogen and oxygen is arranged on before the internal-combustion engine, because the employed gas source of internal-combustion engine is the isolated oxygen of gas separation unit, therefore can make internal-combustion engine have enough oxygen and come and fossil fuel mixed combustion, and then be difficult for producing CO (carbon monoxide converter) gas and the hydrocarbon of incomplete combustion.In addition, because main gas is carbon dioxide and water vapour in the high-temp waste gas, so can omit the nitrogen molecule sieve in the molecular particle size screening unit.
Four, mainly be to utilize the first reaction member carbon dioxide and water vapour to be carried out the synthetic reaction of methyl alcohol in the reaction device, but reaction device also can utilize the second reaction member, the 3rd reaction member or the 4th reaction member according to user's demand, synthesizes other generative fuel with corresponding gas.In addition, between the screening of reaction device and molecular particle size unit, electrolysis cells or the gas separation unit, also the pressure that pressurization device increases gas can be set, use auxiliary each reaction member and reach and carry out the required pressure of synthetic reaction.
Certainly; the present invention also can have other various embodiments; in the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make according to the present invention various corresponding changes and distortion, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
