About the Lab
Professor Choongsik Bae's research lab specializes in advanced internal combustion engine technologies, focusing on combustion optimization, emission reduction, and alternative fuel strategies. The lab investigates innovative injection techniques—such as water and dual-fuel direct injection—aimed at improving engine efficiency and mitigating knock under high-compression conditions. Research also emphasizes fundamental studies on fuel-air mixing, ignition delay, and combustion characteristics under HCCI-like and low-temperature combustion regimes. The lab combines experimental analysis with advanced diagnostics, including in-cylinder pressure measurements and spray imaging, to develop cleaner and more efficient engine systems.

15Water was directly injected into the cylinder with an injection pressure of 5 MPa to investigate its effect on engine performance and emissions in a gasoline engine. The test engine was a 1.6-L naturally aspirated prototype engine consisted of water direct injection and port fuel injection systems. The engine featured a compression ratio of 13.5. Commercial gasoline direct injection injectors were used to inject the water. The water was injected at a fixed timing of −120 crank angle degrees afte
