Description
Technical field
The present invention relates to a kind of being arranged in outlet pipe and be used for the catalyst conversion equipment of hydrogen manufacturing, it mainly can improve the efficiency drawing engine heat, sends in engine, make the complete combustion of fuel in engine, reach fuel-efficient, subtract dirty object to manufacture hydrogen.
Background technique
Because vehicle use itself is greenhouse gas emission important sources, be again simultaneously the use department of highly dependence oil, therefore automobile energy-saving subtract carbon is important policy direction.
General for motor vehicle internal combustion engine is reach good ignition efficiency, depot is in the air fuel ratio A value (ratio of mixture of air and fuel of its best of inner setting, be generally 14.5-15.0), fuel can be made under this numerical value to play maximum combustion benefits.Internationally recognizable automaker, when producing fuel-efficient vehicle, in oil, gas mixing, makes air fuel ratio close to this best A value with accurate control gear.
The content of air fuel ratio higher expression fuel is fewer, more can be fuel-efficient, but often causes engine instability and concussion, is also short of enough horsepower to travel.When air fuel ratio is greater than A value, represent that fuel is relatively thin.Be then the state of lean combustion in engine during igniting.The time of lean combustion meeting hangfire, make, in engine, phenomenon of detonation occurs, to such an extent as to engine running has some setbacks.When the engine generation phenomenon of detonation of automobile, vehicle can produce strenuous vibration, causes the decline of engine efficiency, and has flame-out misgivings, easily damages because of pinking car body and in-vehicle apparatus.
The oil that fuel tank is sent and the air that intake manifold inputs, enter ignition in engine, blast upon mixing, and the piston work done in drive engine.About there is the fuel unburned of 1/3 complete in combustion, and discharged by outlet pipe with waste gas, pollute.When air fuel ratio is too low, the incomplete phenomenon of fuel combustion can be there is, make exhaust emission pollution degree higher, affect air quality, harmful environmental protection.Extremely low (the 0.017MJ in Combustion Energy rank due to hydrogen; Gasoline, 0.29MJ), rapid combustion and its flame velocity (3.2-4.4m/s) are fast more than the flame velocity (0.34m/s) of gasoline, therefore, professors' hydrogenation in engine of Massachusetts Institute Technology, combustion-supporting to improve the combustion efficiency of fuel oil at engine by hydrogen, make originally cannot complete stability burning fuel burn instantaneously totally, also exempt the pinking of engine, more make the carbon content in the waste gas of discharge reduce, decreasing pollution.
The practice of present stage, desired hydrogen is a kind of from high-pressure hydrogen cylinder or hydrogen storing tank, the hydrogen that the another kind of electrolysis from water or electricity slurry restructuring (Plasmareforming) produce.The former storage hydrogen storage equipment used is heavy, and expensive, storage volume is limited, cannot use continuously for a long time, and these shortcomings limit the practicability of this method.
Brine electrolysis obtains the method for hydrogen, has following shortcoming:
1) hydrogen produced mixes with the ratio of oxygen 2 to 1 (67% hydrogen and 33% oxygen), (4-74%H in the auto-ignition ranges of hydrogen
2), there is the danger of blast,
2) the desired electric power of water electrolysis (4-5 degree/cubic meter hydrogen) produced from the running of fuel oil at engine indirectly, if amounts of hydrogen is high, causes the waste of fuel oil, offsets the benefit that hydrogen is combustion-supporting, if the amounts of hydrogen injected is low, then benefit is unevident.So method is also difficult to the benefit reaching expection.
Obtain hydrogen with electricity slurry recombination method, the electric energy with battery must be taken out, by gasoline transformation of ownership hydrogen on car, carry out the combustion-supporting of hydrogen.Developed by the researcher of Massachusetts Institute Technology, and be modified to the automotive engineering company IAV of German automobiles and produce hydrogen storage equipment by means of on car, add 15 ~ 30% hydrogen in existing car engine, reach lifting 30% energy efficiency and reduce fuel cost, and because the help of hydrogen makes fuel burn more completely, reduce the discharge amount of waste gas, more effectively reducing being disposed to of NOx does not almost have, and the equipment of this method is complicated, expensive, and its density of hydrogen is very low, about 12-18%, benefit is limited.Therefore commercial product is lacked so far.
For breaking through shortcoming and the restriction of above-mentioned three kinds of methods, do not changing in original Structure of Internal-Combustion Engine situation, the present invention, using the equipment utilization engine heat of novelty as the hydrogen manufacturing energy, produces hydrogen, injects engine and reaches the combustion-supporting benefit 20-30% of hydrogen.Figure 1 shows that methyl alcohol reformer 10 is arranged in the mode of the outlet pipe 11 that reclines, to absorb the heat of the waste gas that engine 12 discharges.But the outlet pipe 11 made with the pig iron has many micro-pores, and the property led is poor, by by heat conduction to methyl alcohol reformer 10, absorb enough priming task heats to methyl alcohol reformer 10, when costing 20 ~ 30 minutes, too slowly.
