Research Abstract |
The maicro-nano air-bubble mixed into the gas oil is used for the energy saving and environmental load reduction of diesel engine. The maicro-nano air-bubble was mixed into the fuel line continually by super miniature ejector-type micro and nano air-bubble generator(outer diameter is 20mm, length is 30mm). After the micro air-bubble was separated with a nano air-bubble in a mixing tank, diesel engine performance test with a common-rail injection type was experimented. The results showed that 3% improvement on load average of specific fuel consumption, the 1% improvement of the charging efficiency and a slight decrease in the density of the exhaust smoke, etc. were admitted by mixing the nano air-bubble into the gas oil. It is comfirmed that combustion was promoted and improved by a physical and chemical action in mixing the maicro-nano air-bubble into the gas oil.
