Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1, a kind of diesel engine is mixed the Brown Gas device, comprise a Brown Gas generator 20 to diesel engine 10 air feed, Brown Gas generator 20 is connected to by steam line 30 on the intake manifold 101 of diesel engine 10, and the Brown Gas that Brown Gas generator 20 is produced mixes diesel engine 10 cylinders as combustion improver and participates in burning; Brown Gas generator 20 adopts the mode of the outer air feed of cylinder to diesel engine 10 air feed, and the outer air feed of cylinder is divided into again the suction tude mixed gas supply and two kinds of forms are sprayed in air inlet;
The suction tude mixed gas supply is that the intake manifold is upper sends mixed gas into motor, suction pressure maximum while also making at full capacity by certain control unit, suction pressure minimum during low-load by the Brown Gas generator is arranged on; The valve opening angle of perhaps controlling in steam line by mechanical device is regulated air demand, and usings a small amount of diesel oil as light fluid;
The air inlet spray regime is that mixed gas is introduced to intake manifold or suction port place, gas control system utilizes gas spray valve to realize controlling, the injection valve that high-speed electromagnetic valve is housed adopts the pulse width modulation controlled mode, according to the instruction of ECU (Electrical Control Unit), regularly to the intake manifold injection mixed gas of cylinder, the mixed gas of ejection is mixed into cylinder with the fresh air that enters motor; If a large flow mixed gas injection valve is arranged on to the intake manifold of internal-combustion engine, be called the automatically controlled single-point discharge formula of mixed gas aeration motor, relatively be typically the jet charge inter cooling natural gas engine of the C automatically controlled intake duct single-point of series of Cummins, this mode adopts automatically controlled single-point discharge, and carry out closed loop control in conjunction with lambda sensor, can more accurately control air fuel ratio, thereby make motor there is Economy and emission performance preferably;
Tempering is that steam line is mixed the common abnormal combustion phenomenon of Brown Gas motor, and it makes engine running undesired, and hydraulic performance decline easily damages again component.Tempering easily occurs in the situation of high compression ratio, high load (the agent mixed gas is denseer).Reason is under high compression ratio, high load, and the heat that fuel is put into is many, to such an extent as to row's temperature raises to some extent, high-speed working condition easily makes burning delay also can the row's of making temperature rise.After IO Intake Valve Opens, residual gas still keeps higher temperature like this, because the ignition energy of Brown Gas is low, the boundary line that catches fire is wide, so very easily make Brown Gas be lighted by the residual gas of high temperature in air inlet forms, scurries into intake duct, produces tempering phenomenon.In addition, under the high compression ratio high load, cylinder temperature is high, easily causes some incandescent spot (spark plug, exhaust valve head etc.), and mixed gas is easily lighted by these incandescent spots and caused pre-ignition and tempering.Some sediments also can become incandescent spot as carbon distribution in cylinder, and this class tempering rich mixture rear engine of being in can be recovered steady running again.This tempering may be due in weak mixture, and the residual gas relative amount is many, and under this weak mixture, velocity of propagation of flame is very low, and burning is delayed, Exhaust temperature rise, and the oxygen content in residual gas is high, therefore may be lighted and be caused tempering in suction tude by Brown Gas.
The method of inhibition commonly used and elimination tempering has: (1) sprays Brown Gas in the intake process later stage; (2) adopt Brown Gas spray regime in cylinder; (3) adopt EGR; (4) the reduction intake temperature of adopting an effective measure, as spray liquid hydrogen, water spray or water spray cool air etc.This device adopts engine inlets to add the Brown Gas mode, without engine structure is transformed, has higher practicability.Therefore this device adopts two-stage tempering design, as shown in Figure 2, one one-way valve 301 and a water resistance are installed every intake duct 302 on the admission line between Brown Gas generator 20 and diesel engine 10 intake manifolds, adopt the design of two-stage backfireproof, first order one-way valve 301 can guarantee the one-way flow of Brown Gas, the second level adopts the mode of water resistance every intake duct 302 and Brown Gas, and simple in structure, backfireproof is effective.
As shown in Figure 3, Brown Gas generator 20 comprises in one presses SPE brine electrolysis oxygenerator and connected SPE electrolytic bath 201, and SPE electrolytic bath 201 is connected with the high-frequency electrolysis signal plate through DC current regulator power supply, and water electrolysis is become to Brown Gas; Middle pressure SPE brine electrolysis oxygenerator comprises hydrogen moisture trap 202, oxygen moisture trap 203, water circulation system, gas system, cooling system, water charging system and safety system;
