Description
Technical field
The present invention relates to a kind of automobile fuel saving discharge-reducing method, particularly a kind of oil-saving discharging-reducing device and application process thereof of fuel-engined vehicle.
Background technique
Current, save the energy and discharge the focus that becomes worldwide attention with reducing.The year consumption of China's fuel oil surpasses 200,000,000 tons, saves fuel oil and reduces noxious gas emission, and is significant.With hydrogen as fuel is the target that people pursue always, because compare with fuel oil, the combustion value of hydrogen is higher, and does not have discharge of poisonous waste fully.Among hydrogen-burning automobile is being developed always, comprise being the automobile of power with the fuel cell at home and abroad with hydrogen storing alloy, High Pressure Hydrogen or liquid hydrogen automobile as hydrogen source, and fuel oil/hydrogen PHEV.These are with the automobile of hydrogen as main fuel or part of fuel; Also need technical important breakthrough at present: with the hydrogen storing alloy is the hydrogen-burning automobile of hydrogen source; The deadweight of hydrogen source is too big; The mileage that once fills the hydrogen drivable when being hydrogen source with High Pressure Hydrogen (at present upper limit 70MPa) still adds once the mileage of oily drivable, the supply of the hydrogen fuel when being hydrogen source with the liquid hydrogen, the efficient of fuel cell and price much smaller than fuel-engined vehicle; Adding the Security of hydrogen source system and the construction of Economy and hydrogen supply network etc., all is an open question still at present.
Summary of the invention
To the problem that existing fuel-engined vehicle exists aspect practical, the present invention provides a kind of oil-saving discharging-reducing device and application process thereof of fuel-engined vehicle, through in fuel oil, adding micro-hydrogen, to improve firing behavior, increases combustion efficiency.

The material of above-mentioned hydrogen basin is that aluminum alloy, steel or resin strengthen metallic material.
Above-mentioned hydrogen storing alloy is selected LaNi for use
5, MmNi
5(Mm is a mishmetal) or modification V, the equilibrium at room temperature Hydrogen Vapor Pressure of hydrogen storing alloy is 0.1 ~ 0.5MPa.
The valve lower end of above-mentioned hydrogen basin is provided with the porous material filter sheet; Its material is a stainless steel, and the aperture is 0.1 ~ 0.5 micron.
Above-mentioned hydrogen pipeline is selected withstand voltage plastic cement pipe or Stainless Steel Tube for use.
Above-mentioned flow dontroller is selected gas rotameter or control metering-orifice for use.
The solenoid valve that is connected in series in the above-mentioned hydrogen pipeline be connected both synchronous operations with the FP Fuel Pump Relay of motor.
The application process of the oil-saving discharging-reducing device of fuel-engined vehicle of the present invention does; Ato unit, solenoid valve is opened with FP Fuel Pump Relay simultaneously, and the oil in the fuel tank enters into the firing chamber of motor; Hydrogen under the situation of valve open in the hydrogen basin gets into hydrogen pipeline through valve; Enter into engine intake manifold through solenoid valve and flow dontroller again, arrive the gas handling system of motor, finally get into the firing chamber; The flow of control hydrogen in hydrogen pipeline is 50 ~ 500mL/min.
The hydrogen methods that fills of above-mentioned hydrogen basin is: the hydrogen storing alloy fragmentation is placed in the hydrogen basin and fills; Hydrogen gas cylinder is connected with the hydrogen basin; Charge into for the first time the time 30 ~ 50h of hydrogen; Fill equilibrium hydrogen pressure that hydrogen accomplishes hydrogen storing alloy in the hydrogen basin of back at 0.1 ~ 0.5MPa, activation also is ground into particle in small, broken bits to hydrogen storing alloy automatically in the hydrogen process charging into for the first time; When filling hydrogen once more later on, can reach 50 ~ 80% of total storage hydrogen capacity at the 0.5-2h hydrogen storage amount.
In the said method, when the subsidiary pressure gauge of hydrogen basin shows that hydrogen pressure < during 0.1MPa, fills hydrogen to the hydrogen basin once more.
Above-mentioned porous material filter sheet can prevent that the hydrogen storing alloy particle after the activation from getting into hydrogen pipeline with the hydrogen effusion from the hydrogen basin.
The present invention compared with prior art; The good effect of outstanding feature and generation is: utilize the reversible hydrogen of hydrogen storing alloy big (the storage hydrogen density is far above high-pressure gaseous storage hydrogen and liquid storage hydrogen), inhale and put that hydrogen (is inhaled hydrogen and can be reached semi-saturation) rapidly in a few minutes, equilibrium hydrogen forces down thereby the characteristics of safety (equilibrium hydrogen pressure during room temperature＜0.5MPa) with put hydrogen purity height (> 99.999%); It is positioned in the hydrogen basin, becomes high, the safe in utilization hydrogen source of storage hydrogen density; When oil inflame, add small quantity of hydrogen, can significantly improve the firing behavior of fuel oil, comprise and reduce ignition energy (the about 0.02mJ of the ignition energy of hydrogen; Be merely the gasoline ignition energy 1/10th), (the igniting velocity of propagation of hydrogen is 4.85m/s, fast 5 times than gasoline to increase the igniting velocity of propagation;), (flame-out gap has only 0.06 second during combustion of hydrogen, is 1/3rd of gasoline to improve flame distribution; Less flame-out gap makes flame distribution arrive the arbitrary portion of automobile cylinder, comprises the piston ring inner width, helps removing rapidly original carbon distribution; Avoid producing new carbon distribution simultaneously, can effectively protect motor, increase the service life); Thereby reach the saving fuel consume, reduce disposal of pollutants and the effect that increases automobile power.Through overtesting, compare with not adding hydrogen, the present invention can make fuel-engined vehicle save fuel oil 5 ~ 22%, obviously reduces smog emission, increases power output, reduces the user cost of fuel-engined vehicle; The hydrogen basin can fill hydrogen-put hydrogen repeatedly to be used more than 500 times, and cost safe and convenient to use is low, needs hardly to safeguard.
