Description
Technical field
The present invention relates to a kind of being arranged on and in outlet pipe, be used for the catalyst conversion equipment of hydrogen manufacturing, it mainly can improve the efficiency of drawing engine heat, to manufacture hydrogen, sends in engine, makes the complete combustion of fuel in engine, reaches fuel-efficient, subtracts dirty object.
Background technique
Because vehicle use itself is greenhouse gas emission important sources, be again the use department of highly relying on oil simultaneously, therefore automobile energy-saving subtracts carbon, be important policy direction.
General for motor vehicle internal combustion engine is to reach good ignition efficiency, and depot, in its best air fuel ratio A value (ratio of mixture of air and fuel, is generally 14.5-15.0) of inner setting, can make fuel bring into play maximum burning benefit under this numerical value.Internationally recognizable automaker, when producing fuel-efficient vehicle, mixes at oil, gas, with accurate control gear, makes air fuel ratio approach this best A value.
The content of the higher expression fuel of air fuel ratio is fewer, more can be fuel-efficient, but often cause the unstable and concussion of engine, be also short of enough horsepower and travel.When air fuel ratio is greater than A value, represent that fuel is for relatively thin.It while lighting a fire, in engine, is the state of lean combustion.The time of lean combustion meeting hangfire, make generation phenomenon of detonation in engine, 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, to car body and in-vehicle apparatus easily because pinking damages.
The air of the oil that fuel tank is sent and intake manifold input enters ignition in engine, blast after mixing, and piston work done in drive engine.In combustion process, approximately there is 1/3 fuel unburned complete, and discharged by outlet pipe with waste gas, pollute.When air fuel ratio is too low, can there is the incomplete phenomenon of fuel combustion, 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, the professors of Massachusetts Institute Technology hydrogenation in engine, combustion-supporting to improve fuel oil in the combustion efficiency of engine by hydrogen, make originally cannot complete stability burning fuel moment burning totally, also exempt the pinking of engine, the carbon content in the waste gas that more makes to discharge reduces, and reduces and pollutes.
The practice of present stage, desired hydrogen is a kind of from high pressure hydrogen steel cylinder or hydrogen storing tank, the hydrogen that the another kind of electrolysis from water or electricity slurry restructuring (Plasma reforming) produce.The former storage hydrogen storage equipment used is heavy, costliness, storage volume is limited, cannot use continuously for a long time, these drawbacks limit the practicability of this method.
Brine electrolysis obtains the method for hydrogen, has following shortcoming:
1) hydrogen producing mixes (67% hydrogen and 33% oxygen), (4-74%H within the scope of the spontaneous combustion of hydrogen with the ratio of oxygen 2 to 1
2), there is the danger of blast,
2) the desired electric power of water electrolysis (4-5 degree/cubic meter hydrogen) produces in the running of engine from fuel oil indirectly, if amounts of hydrogen height causes the waste of fuel oil, offsets the combustion-supporting benefit of hydrogen, if the amounts of hydrogen of injecting is low, benefit is unclear.So method is also difficult to reach the benefit of expection.
With electricity slurry recombination method, obtain hydrogen, must take out the electric energy with battery, on car, by gasoline transformation of ownership hydrogen, carry out the combustion-supporting of hydrogen.Researcher by Massachusetts Institute Technology is developed, and be modified to by means of producing hydrogen storage equipment on car with the IAV of automotive engineering company of German automobiles, add 15 ~ 30% hydrogen in existing car engine, reach and promote 30% energy efficiency reduction fuel cost, and because the help of hydrogen is burnt fuel more completely, the discharge amount that reduces waste gas, more effectively reducing being disposed to almost of NOx does not 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 lack so far commercial product.
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 is usingd novel equipment utilization engine heat 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 arranges in the mode of the outlet pipe 11 that reclines, to absorb the heat of the waste gas that engine 12 discharged.Yet the outlet pipe 11 made from the pig iron has many micro-pores, the property led is poor, by starting that heat is conducted to methyl alcohol reformer 10, to methyl alcohol reformer 10, absorbs enough priming task heats, while costing 20 ~ 30 minutes, too slow.
