Embodiment Construction
[0013] The present invention is described in more detail below in conjunction with accompanying drawing example:
[0014] combine figure 1 , including diesel engine 1, water tank 4, water pump 7, steam generator 8, water circulation pipeline 9, semipermeable membranes 2, 3, EGR pipeline 14, variable semipermeable membrane baffles 12, 13, etc. The water circulation system is composed of a water tank 4, a water pump 7, a steam generator 8, and a variable semi-permeable membrane baffle 12, and is connected to the rear air inlet of the compressor through the semi-permeable membrane 3. , lead it to the rear air inlet of the compressor, and connect with the air inlet 10 through the semi-permeable membrane 2 . When the diesel engine is working, because the air in the intake passage 10 is compressed by the compressor, the concentration of oxygen molecules and nitrogen molecules is high, while the concentration of water molecules in the waterway 9 is high, and the concentration of res...
