Because method (1) relates to the new substitute fuel of research and development and improves the petroleum refining technology, large-scale promotion still remains time; Method (3) is primarily aimed at purification, the processing of tail gas, does not relate to the clean combustion technology, can only cure the symptoms, not the disease.Therefore method (2) is at present uniquely fundamentally to control the tail gas pollution problem of diesel engine by effective transformation can realize the technology of clean combustion to existing diesel engine, has been subjected to the high praise of each side.
But in the research of method (2), following technical problem: a, variable-area turbocharger appear, thereby the pressure that utilizes variable cross section to regulate waste gas increases the rotating speed of pressurized machine, but the variable cross section in this technology uses material requirements very high, at present domestic can't finishing.B, the gas compressor that adopts multistage supercharging or direct current generator to drive abroad, the one, mechanism is very complicated, and manufacture difficulty is big, cost is high, and the 2nd, the consumption of direct current electric energy is many, and inrush current is very big, and existing vehicle power can't satisfy.C, the domestic high pressure air that has the unit employing to brake gas tank are carried out tonifying Qi, repeatedly use the back to influence brake safe.D, utilize electric booster, but pressurized effect and not obvious, reason is: 1, the electric booster revolution does not reach the revolution of exhaust-gas turbocharger far away, and the pressure of gas is lower than the gas pressure after the exhaust-gas turbocharger supercharging after the supercharging; 2, electric booster still exists hysteresis effect starting time.
The model utility content
The technical problems to be solved in the utility model is: propose a kind of structure and relate to the diesel engine combustion oil gas intelligent control proportioning device accurate, easy for installation, that cost is low, effective, safe.
The technological scheme that the utility model adopted is: a kind of diesel engine combustion oil gas intelligent control proportioning device, comprise the ICS intercooler system that turbine increases device and is connected with turbosupercharger, ICS intercooler system also connects the suction tude of motor, be parallel with one group of blowdown pipe on the suction tude of described motor, add solenoid valve on the described blowdown pipe successively, first gas bag, pressure regulator valve, second gas bag and air compressor, described air compressor is the inflation of second gas bag, by after the pressure regulator valve pressure regulation gas in second gas bag being put to first gas bag, utilize the solenoid valve unlatching or close pressure required when engine speed moment change is provided.
Further, in order in engine air inlet tube, to set up a fraction of pressure earlier, and prevent that returning of gas scurried after the tonifying Qi, add on the connecting tube of turbosupercharger described in the utility model and ICS intercooler system on the connecting tube of one-way valve or ICS intercooler system and motor and add one-way valve.
Further, for can be accurately to carrying out supercharging in the engine air inlet tube, solenoid valve described in the utility model be controlled by ECU (Electrical Control Unit), and ECU (Electrical Control Unit) is gathered the unlatching of control electromagnetic valve behind the throttle signal or closed.
Again further specifically, be provided with pressure transducer in second gas bag described in the utility model, air compressor is accepted the signal change working state that described pressure transducer sends.The pressure transducer acknowledge(ment) signal makes compressor with the race of engine when the pressure in second gas bag reaches certain value; When the pressure in second gas bag was lower than certain value, air compressor was accepted sensor signal normally with engine operation.
The beneficial effects of the utility model are: after using the utility model, the required tolerance satisfaction of motor moment acceleration strengthens, smoke intensity reduces significantly, utilize the smoke opacity method to measure, the smoke intensity reduced rate is 30～60%, other effulents also have corresponding minimizing, quicken power and are significantly improved.From the angle of social effect, reduce the pollutant of city bus discharging, improve the urban life environment, really the living environment of the realization green on the meaning, environmental protection, low-carbon (LC).
