Background technique
At present, along with development of modernization, the traffic tool increase day by day; the environmental pollution that exhaust emissions caused of motor vehicle exhaust gases is more serious; on the other hand, worldwide be faced with serious energy crisis, only enough human the uses 40 years of the underground petroleum reserves of verifying.Therefore, administer to pollute energy saving and arrived instant place, reduce motor vehicle exhaust gases discharging and the fuel-economizing problem generally be concerned about of people just.Existing Motor Vehicle is that gasoline, diesel oil are done fuel mostly, utilizes airborne comburant oxygen.Because the air oxygen content is lower, it is insufficient directly to cause burning, and the burning energy consumption is big, increases oil consumption greatly, increases user cost, and this also is the problem that automobile industry is concerned about for many years always.For many years, motor car engine enterprise is improving the cylinder body structure and the air inlet system of motor car engine always, comprise turbosupercharging etc., and the manufacturer of many fuel economizers also releases dissimilar fuel economizers, comprise magnetization method and pre-heating mean etc., all be what to adopt with oily fuel-economizing, effect is undesirable, because oil inflame needs sufficient oxygen to participate in combustion reaction, and a large amount of oxygen derives from a large amount of air, and oxygen only accounts for about 21% in air, and nitrogen accounts for about 79%, therefore, a large amount of air participates in combustion process and has taken away a large amount of heats, therefore, even fully burning, because temperature of exhaust fume approaches 700 degree, taking away a large amount of used heat becomes the main cause of internal-combustion engine thermal loss, and same, a large amount of nitrogen can hinder the abundant combustion reaction of oxygen and fuel oil in the air, therefore, insufficient generation carbon monoxide of oil inflame and hydrocarbon are another low main causes of the efficiency of internal combustion engine.
Fuel combustion process be a complexity the chain reaction process, as shown in Figure 2, in the combustion process, hydrocarbon fuel (RH) dehydrogenation generates alkyl (R '), alkyl (R ') continue oxidation generate superoxide (R ' O
3), superoxide (R ' O
3) being degenerated to aldehydes (R ' CHO), the aldehydes decarburization generates CO and alkyl (R '), and alkyl (R ') repeats above-mentioned chain reaction. in combustion process, hydrocarbon fuel becomes CO through such chain reaction step initial oxidation, continues to be oxidized to CO then
2The velocity of combustion of carbon monoxide and air mixture is very little, and when having hydrogenous material to exist, velocity of combustion will significantly improve.When " drying " carbon monoxide unwatering and hydrogen contacts with oxygen, then can not react below 700 ℃.The condition that the oxidative chain lock reactor (as shown in Figure 3) of carbon monoxide is set up is that H must be arranged, and the active centre that atoms such as O and OH (group) are formed participates in reaction, because OH+CO-〉CO
2+ H reaction constantly produces new H, in case reaction starts, will circulate down, even stop to send into Blang's gas, reaction also can be kept, hydrogen " participated in reaction but finally get back to ortho states ".H
2And products of combustion H
2O also has very intense influence to detonation and flame radiation.
Therefore, the method that fundamentally solves motor-driven overall height oil consumption is to send into H to car combustion engine, O, radicals such as OH promote oil inflame chain reaction and and feed oxygen-rich gas reducing the demand of internal-combustion engine to car combustion engine to air, thereby avoid waste-heat rejection.
