A study of reducing exhaust gas emissions such as diesel engine has been progressing actively due to unstable international oil prices and strict emission regulations. However, it is very difficult to reduce exhaust gas emissions since there is a trade-off between fuel efficiency and reducing exhaust gas emissions. Therefore, a lot of study started being interested in alternative energy such as hydrogen, bio-diesel, fuel cell and solar system. Especially hydrogen energy(H2) which is pollution free energy can be used in any fields like fossil fuel.
In this study, small amount of H2 was added into intake air to improve fuel-efficiency and reduce exhaust gas emissions as enhance of combustion ability of internal combustion engine.
The H2 is produced by water electrolytic method which is called proton exchange membrane water electrolyzer(PEMWE). Furthermore, experimental method is RPM(1000~2000 RPM) and load conditions(BMEP 2.0 - 10.0bar) influences fuel-efficiency and exhaust gas emission.
There was a no outstanding effect of diesel combustion by adding small amount of H2 gas, however there was the reduction of exhaust gas emission and improvement of fuel consumption up to 6% related to some amount of supply of H2.
According to these variety of hydrogen experiments, this study showed that diesel engines with some amount of H2 can be used effectively for transportation such as Ship’s Engine and Vehicle to reduce exhaust gas emissions and improve fuel efficiency.
