Combustion Engineering Lab
Machine-translated · View original
A lab that explores the combustion and ignition of next-generation fuels through experiments and analysis.
AboutAbout the lab
Unraveling how combustion works through measurement and analysis.
The Combustion Engineering Lab conducts research and development on the combustion of next-generation fuels such as ammonia, hydrogen, and biomass, as well as on new combustion and ignition technologies.
The lab investigates how soot and nitrogen oxides form in fields where pulverized coal and oil droplets burn, using laser measurement that does not disturb the combustion field.
It also works on combustion simulation and modeling that take reaction mechanisms into account, targeting jet flames and ammonia combustion furnaces, among others.
The lab belongs to the Department of Mechanical Engineering, Graduate School of Engineering, the University of Osaka, and is introduced under the name “Combustion Engineering Lab” on the lab's website.
Key terms
- Energy carrier
- A medium that carries hydrogen energy from where it is produced to where it is consumed. Ammonia is attracting attention for this role.
- Plasma-assisted combustion
- A field combining plasma engineering and combustion engineering. It is attracting attention for lean combustion and for burning fuels that are hard to ignite.
- Elementary reaction
- An individual reaction that takes place in the course of combustion. The whole set of elementary reactions is called a reaction mechanism.

ResearchResearch themes
The Combustion Engineering Lab researches the combustion of next-generation fuels such as ammonia, hydrogen, and biomass, as well as plasma-assisted combustion and ignition. It approaches the mechanisms of combustion through both experimental measurement and numerical analysis that takes reaction mechanisms into account.
*Illustrative imageCombustion of next-generation fuels
Aiming at the use of hydrogen and of ammonia, which is attracting attention as an energy carrier, as fuels, the lab clarifies combustion characteristics and develops fundamental technologies through experiments and numerical analysis. It also works on the effective use of biomass fuels and on drafting scenarios for societal implementation.
*Illustrative imageNew combustion and ignition technologies
Focusing on plasma-assisted combustion and ignition, the lab studies the ignition of ultra-lean mixtures using laser-induced breakdown, and combustion assistance using non-equilibrium plasma.
Measuring combustion fields with lasers
To clarify the mechanisms by which soot and nitrogen oxides form in pulverized coal combustion fields and oil droplet cluster combustion fields, the lab captures these phenomena in detail with non-contact applied laser measurement that does not disturb the combustion field, and works on proposing physical models.
Combustion simulation and modeling
Combustion proceeds through many elementary reactions. Targeting jet flames, spray flames, diesel engines, ammonia combustion furnaces, and more, the lab uses analysis that takes reaction mechanisms into account to propose physical models and clarify combustion mechanisms.
