Study at TCU


Name ITO Akemi
Official Title Professor
Affiliation Mechanical Engineering, Sience and Engineering
Profile My research interest is laid on the areas of engine tribology and advanced power source for mobility. For the former area, the mechanism of lubrication for piston/cylinder system, i.e. oil consumption, piston friction and so on, are analyzed using a lot of unique measurement methods in my laboratory. For the latter area, the research for a hydrogen fueled engine of practical use are carried out.
Research Field(Keyword & Summary)
  1. 1) Internal combustion engine, Tribology, Measurement

    Tribological research for internal conbustion engines aims optimization of sliding surface of engine components. The shape of the sliding surface, temperature, load and velocity are required for analysis and development of measurement method for those parameter is essencial.

  2. 2) Hydrogen, Internal combustion engine

    Carbon free power sources for mobility are required for curb geenhouse effects. Heavy duty vehicles are an area that is difficult to electrify, and it is difficult to drive them with an electric motor. Hydrogen fueled engiknes can be one of the important candidates for heavy duty vehicle power sources. Improving the durability of hydrogen fueled engines is the future issue.
