In our Combustion Laboratory, we conduct studies on combustion and its new utilizations including internal combustion engines for automotives and aircrafts and low emission, development of micro-combustors, fire safety in space and surface modification by flame. Humanity obtains energy through combustion, and clean and efficient combustion technology is a recent important issue. For higher thermal efficiency and lower emission of internal combustion engines, we study on HCCI combustion phenomena and development of non-intrusive temperature distribution measurement technique with infrared emission method, which can be applied to measurement inside the cylinder and high enthalpy supersonic exhaust jet of the pre-cooled turbojet engine, which is developed for an aircraft's engine of next generation. We also study on micro-combustors, which keep combustion inside a very small volume less than quenching distance, and develop a handy personal micro-cogenerator which consists of a micro-combustor, thermo-electric modules and fuel-air supplying system. For fire safety study, we are now carrying out the study on flammability of solid materials in microgravity environment, which is an international project to propose a new fire safety standard in space, and orbital experiments are planned in Kibo module of International Space Station.
