The tail gas discharged after engine operation carries out purified treatment outside machine, mainly for contaminant particle (PM) and nitrogen oxide (NO
x) carry out purified treatment, dedusting is absorbed, to nitrogen oxide (NO to particulate (PM) aqueous slkali physical dissolution
x) adopt the denitration of same aqueous slkali chemical absorption, then by the particulate (PM) of remnants and nitrogen oxide (NO
x) use solid matter physical absorption further, after two kinds of Combination of Methods purified treatment, the tail gas of motor discharge can qualified discharge.
Above-mentioned engine booster and tail gas clean-up process are controlled by the isochronous controller assembly of microprocessor, make its engine booster and tail gas clean-up process become integrated synchronous and run, to obtain the maximal efficiency of engine booster and tail gas clean-up.
Summary of the invention
Two turbine air pump is arranged in naturally aspirated engine air-strainer or in corresponding engine air inlet tube.
Automatically controlled pair of turbine gas pump power adopts high-performance brushless direct-current external rotor electric machine, external rotor magnetic poles rare earth material makes high magnetic conduction magnetic pole, to reduce motor volume and to increase motor torque and rotating speed, external rotor rotating shaft two ends respectively fill one group of turbine blade, form single motor single axle double-turbine structure, motor Vehicular accumulator cell provides electric energy.
Two turbine air pump is passed through by the filtered air of air-strainer, two turbine gas pump motor is under the control of isochronous controller assembly, two turbine air pump is driven to carry out twice dual precompression supercharging to filtered air, along with the increase of air quantity, oil sprayer also adds fuel delivery per cycle accordingly under the instruction of vehicle-mounted (ECU), the air fuel ratio maintaining motor is substantially constant, after mixed gas compresses by piston, improve the relative compression ratio of motor, light mixed gas Thorough combustion, heat energy and the thermal efficiency obtain and improve, the power performance of motor is improved and improves, simultaneously after mixed gas Thorough combustion, the growing amount of exhaust pollutant is reduced accordingly, the exhaust pollutant of motor discharge reduces thereupon.
The consumption rate reducing fuel oil after engine booster is embodied in two aspects: the first improves starts relative compression ratio, after mixed gas Thorough combustion, the thermal efficiency improves, under the original power of motor and torque, the consumption rate of fuel oil declines, it two is under ensureing the original power of motor and torque, suitably can reduce the rotating speed of motor, mechanical loss and the wearing and tearing of motor reduce, Motor Vehicle car load kinetic energy increases, it is still higher that driver need not refuel the speed of a motor vehicle, is reduced and declines relative to the consumption rate of fuel oil.
For ensureing that amount of charge air supplies consistent with engine operating condition demand, isochronous controller assembly has supercharging synchronization control characteristic.
