We are the specialists in engine research.

Engine Laboratory is devoted to fundamental research on internal combustion engines including spark ignition and diesel engines. It is one of the several thermo-fluid research laboratories in Department of Mechanical Engineering, KAIST.

Our research efforts are under way with an eye on a highly efficient and clean engines utilizing new technologies such as homogeneous charge compression ignition (HCCI), low-temperature diesel combustion, alternative fuel, direct injection spark-ignition(DISI) and high speed direct-injection(HSDI) diesel engines for the sake of developing next generation engines. Also, lots of diagnostic techniques such as pressure measurement, visualization using high-speed camera, laser applications (LDV, PDA, LIF, LII) are used to clarify the physical sources occuring in engine combustion.

(*More details can be found in “Project” section.)

Around 15 reseachers including post-doc fellows, ph.d. and masters students are working on their own research topics. We welcomes two or three new masters students every year. If you are interested in post-doc, ph.d. students or visiting researcher positions, please contact Prof. Bae directly.

LTC (Low Temperature Combustion)

Background: Internal Combustion Engines are primary power sources of the commercial vehicles. But its hazardous emissions threaten our health. Especially in diesel engines, high level of nitrogen oxides (NOx) and particulate matter (PM) emissions are serious problems which should be solved. Therefore, recent researches about diesel engines have been ?focused on low …

Alternative Fuels

Background: Fuel economy and emission reductions became the most important issues in power-plants or energy conversion systems as the environmental regulations gets stricter together with green-house-gas (GHG) regulations while the drought of petroleum is coming soon. CO2 has been regarded as a main component among the GHGs. ┬áSome alternative fuels are spotlighted …

DISI (Direct Injection Spark Ignition)

Background: In order to reduce hazardous emissions and the fuel consumption, a direct-injection spark-ignition (DISI) concept was introduced in the gasoline engine technologies. The uniqueness of DISI engines is its operation in stratified mode during low loads and idling by injecting small amount of fuel in a limited region within the combustion …

HCCI (Homogeneous Charge Compression Ignition)

Background: Homogeneous Charge Compression Ignition (HCCI) also termed as Controlled Auto-Ignition (CAI) is a combustion technology for ICE and a potential future-engine-strategy for automobile companies. HCCI is an alternative piston-engine combustion process that can provide efficiencies as high as compression-ignition, direct-injection (CIDI) engines (an advanced version of the commonly known diesel engine) …

HSDI (High Speed Direct Injection)

The KAIST Engine laboratory is focused on researching the combustion and emissions for changing the FIE(Fuel Injection Equipment) and the engine component. For instance, we studied difference between the solenoid type and the piezo-actuated injectors. Also, we research the effect the combustion bowl shape on combustion and emission in diesel engine.
